2.0 IMPORTANT: CONSIGNES DE SECURITE
3.1 Device Capabilities
The C2-1000 series uses the proprietary CORIO ® 2 Engine to perform its functions, being the second generation of the successful CORIO ® products. The CORIO ® 2 technology is a powerful toolset for any application requiring high quality video signal conversion or image manipulation.
All units feature a single video processing and scaling engine, with some unit's also featuring video mixing, keying and fader capabilities.
These functions allow the flexibility for handling a wide range of inputs and outputs, depending on the unit used.
All units are at one in the home and broadcast & display environments. The C2-1000 series offers a range of high-level image processing functions – with each model designed to fulfill a particular need.
The following is a summary of the main types of product available in the C2-1000 series, as marked on the front of each unit:
Down Converter
Down converting an image is when a computer PC or HD input is inputted to the unit. The input signal is then converted into a suitable signal which can then be displayed for use on a video screen or television, such as composite video.
Down Converter PLUS
This unit has all the features of a Down Converter, but it also has the added facility to superimpose the inputted computer image on top of an existing video signal. This is achieved with the unit's inbuilt facilities such as Keying, Picture in Picture (PIP), and Fading.
Video Scaler
This unit allows for a standard television video signal, such as Composite Video, to be input into the unit and then converted for use on a computer display. When using this function you can switch back to the computer image by pressing a button. This is known as bypass mode.
Video Scaler PLUS
Video Scaler PLUS has all the features of the Video Scaler unit, but with the added facility of superimposing the converted video signal over the top of an existing computer video signal. This is achieved by using the unit's inbuilt features such as Keying, Picture in Picture (PIP), Fading, and the facility to switch between overlaying the foreground over the background and vice versa – background/foreground priority.
Universal Scaler PLUS
This ‘all in one’ converter facility combines the abilities of a Down Converter PLUS and Video Scaler PLUS into one unit with added functionality for image superimposition. This is achieved by using the units inbuilt features such as Keying, Picture in Picture (PIP), Fading, and the facility to switch the between overlaying the foreground over the background and vice versa – background/foreground priority.
3.2 Device Features
General Topography
4:4:4 RGB / YUV sampling provides full bandwidth color which allows precise keying where included in the unit's capabilities. This can be achieved through the transparent (soft) keys on the front of the unit. Each unit's video inputs accommodate multiple video and computer signal formats and resolutions – see specifications at end of manual for full details.
Ultimate flexibility
The C2-1000 series' output signal format flexibility assures that the Native Resolution of virtually any display can be matched. Because of the resolution calculator (included in the Windows® Control Panel), even new resolutions can be added to the unit. Signal parameter adjustments can be made for each video input and are stored in individual non-volatile memories for retrieval once the unit's power has been removed. The Video Scaler units employ pixel adaptive motion compensation to de-interlace fast moving images, and automatic 3:2 Pull-down efficiently de-interlaces video from 24 fps NTSC film.
Simple Control
The unit can be controlled in various ways. One option is to control it from the front panel using the transparent (soft) keys on the front of the unit. Another option would be to control the unit from an infra-red remote control. It can also be controlled via RS-232 using the Windows Control Panel.
The Windows Control Panel is available for download from our Internet site and affords complete control of the unit and adds Scripting to facilitate long, complex sequence of commands.
Finally, a hardware based switcher like the CORIO ® console unit allows the user to control the unit by mimicking a classic video switcher device.
Upgradeability
All C2-1000 units benefit from firmware upgradeability, thus reducing product obsolescence by allowing the installation of the latest version of firmware. This not only applies to the software used to control the unit, but also to the range of resolutions stored inside the unit, the addition of new features, and upgrades to the heart of the image processing hardware – the CORIO®2 scaling engine. See http://www.tvone.com/support for more detail.
4 PRODUCT IMAGES
Your C2-1000 product should look like one of the units below.
Each unit has a different main function (Down Converter, Video Scaler, Universal Scaler) and a subsequently different ability to process video signals.
5 FRONT PANEL CONTROLS
The range of buttons on the front of the unit provides the user with quick easy access for selecting a variety of inputs and features. Since all the units in the C2-1000 series are different, not all of the descriptions below will be applicable to the unit in question. The most notable is the LOCK/MIX/KEY/FADE buttons that are on certain units only.
The multi-directional switch on the front panel provides the user with a way of navigating the on-screen-display (OSD) menu system. The RS232 interface and infra-red remote control also provide further ways of controlling the unit, which are detailed in a later section.
5.1 Button controls
A sub-set of the following buttons will be available on the front of the unit, depending on the model in use:
| Button Common Button Function | |
| Multi-directional switch | Press once to show the on-screen display (OSD). Hold in to cancel the OSD. Press and hold in to store current settings into memory. They will then be restored on power-on, or when RESTORE is pressed. See next section for more information. |
| RGB (n) Selects an RGB input as the current source for conversion. | |
| CV (n) Selects a CV input as the current source for conversion. | |
| YC (n) Selects a YC input as the current source for conversion. | |
| FREEZE Freezes the current image (does not affect any background image) | |
| ZOOM Jumps to the ‘Zoom’ menu item (also steps Zoom between 100%, 150%, 200% and 300% if OSD is not active) | |
| PAN Jumps to the Zoom pan menu item and allows immediate panning of a zoomed image using multi-directional switch. | |
| SIZE Jumps to the ‘Shrink’ menu item and allows immediate adjustment of PIP size. | |
| POS | Jumps to the Shrink pos % menu item and allows immediate adjustment of PIP position. |
| AUTOSET | Activates Autoset for the current analog RGB input |
| PIP | Activate picture-in-picture mode.(Activates and deactivates the Shrink value in the ‘Adjust windows’ menu in the OSD) |
| RESTORE | Hold in briefly to restore to last-saved (power-on) defaults – this is useful to ‘escape’ from non-displayable configurations. Hold in for longer (two beeps) to perform a Factory reset of user settings. |
| STANDBY | Hold in to put the unit into Standby (power-save) mode.Hold in briefly to come out of Standby mode. |
| LOCK Sets | Lock mode to Genlock.This locks the unit’s output to the current Lock source.See ‘Adjust outputs’ menu details. |
| MIX Sets | Lock mode to Lock & Mix, to overlay onto the current Lock source. Use with the KEY and FADE buttons for more flexibility.A 2nd press will swap foreground and background.See ‘Adjust outputs’ menu details. |
| KEY Enables keying – see ‘Adjust keyers’ menu.(Key color defaults to black, so black foreground will disappear.) | |
| FADE Fades out the current image – fades back in on next press. | |
5.2 Multi-directional switch
The on-screen display (OSD) is controlled from the front panel by using the multi-directional switch (m/d switch). This switch can be moved left, right, up or down and also pressed in. These functions let the user navigate through the menu structure or change a parameter, and are detailed in a later section.
5.3 Advanced menus
System
Advanced menus
[Off]
The above menu item must be ‘On’ to activate certain menu items. These typically control the more advanced items in the menus.
5.4 Special button combinations and functions
In addition to the ability to perform a factory reset and forcing certain output resolutions, other button combinations are available:
These button combinations only work when the unit is switched on and active i.e. with the STANDBY/ON LED is off. They will not work in Standby mode, or during power-up.
5.4.1 Locking front panel buttons & IR remote control
This can be performed by pressing STANDBY/ON and RESTORE at the same time. All front panel buttons and IR remote control commands will be disabled, with the exception of repeating the above combination to un-lock the unit and for storing the current locked buttons setting (thus letting you make sure the unit always starts up with the buttons locked). The IR remote's LOCK and STORE buttons will always be active, giving another way to turn button/IR remote locking off.
The STANDBY/ON LED will flash when the unit's buttons are locked.
5.4.2 Factory Reset
If you wish to restore all operational parameters to their original condition, first ensure the unit's in the operational mode, not in Standby where the red power led is illuminated. When it is in the operational mode, hold the RESTORE button in until two beeps are heard.
All stored settings except resolutions are lost when the unit is reset. A Firmware update is the only way to perform a complete factory reset (including resolution data).
5.4.3 Switching units between different resolutions (NTSC, PAL and Default)
Down converters will default to outputting NTSC after a Factory Reset, whilst Video Scalers will default to outputting XGA (1024x768 @ 60Hz). Should your display or output source not support the default resolution, or if you wish to have quick access to an alternate resolution, the following methods below can be used. When you are happy with the output resolution selected, press and hold the multi-directional switch in to store the current settings.
Please note that these changes will have no immediate effect if LOCK or MIX buttons are illuminated, as this means that the output resolution is locked to the Lock source.
5.4.4 Forcing NTSC output resolution
Press and hold the RGB(1) button and FREEZE button together, then release.
5.4.5 Forcing PAL output resolution
Press and hold the RGB(1) button and ZOOM button together, then release.
5.4.6 Forcing default output resolution
Press and hold the RGB(1) button and PAN button together, then release. The default output resolution depends on the type of unit you have – see above.
6 AUDIO / VIDEO INPUTS AND OUTPUTS
The C2-1000 series has a number of different inputs and outputs – see earlier front and rear panel diagrams to see what is available on your unit.
6.1 Computer & Video inputs
The PC/HD input can accept:
Analog RGBHV
RGsB (sync on green)
RGBS (separate sync at TTL levels)
YUV/YPbPr (including tri-level)
In most cases, the particular input being used will be auto-detected. See 'Adjust sources' for more information on manually selecting an input type. On some units such as Video Scalers, the PC/HD input is there just to loop the PC image through to the PC monitor in 'bypass' mode.
The YUV/YPbPr (component) input can also be switched to RGsB (sync on green) mode if desired – see 'Adjust sources' for more information on manually selecting an input type.
CV and YC inputs can accept either standard NTSC or PAL inputs – for example, from a video camera, VCR, DVD player, gaming device, etc. PAL and NTSC detection is automatic.
6.2 Computer & Video outputs
The PC/HD and RGBHV outputs can use:
Analog RGBHV
RGsB (sync on green)
RGBS (separate sync at TTL levels) YUV/YPbPr (including tri-level).
However, please note that on some units such as Down Converters, the RGB output is there just to loop the PC image through to the PC monitor. On Video Scalers, bypass mode (with the unit in Standby) will feed PC/HD in to PC/HD out directly.
YUV/YPbPr (component) outputs can also be switched to RGsB (sync on green) mode if desired - see 'Adjust outputs' for more information.
CV and YC outputs always function simultaneously and can be set to either standard NTSC or PAL – see 'Adjust outputs' for more information. Note that RGB/YUV/YPbPr outputs also function in this mode.
If your unit has a UTP output, this output reflects whatever is at the PC/HD/YUV output, but is encoded to be compatible with the following UTP receivers at up to 300 meters of UTP cable.
| Model Number Format Audio Max Distance | ||
| 1T-CT-442 RGBHV None 150m (500') | ||
| 1T-CT-444 RGBHV None 300m (1000') | ||
| 1T-CT-452* RGBHV None 150m (500') | ||
| 1T-CT-456* RGBHV None 300m (1000') | ||
| 1T-CT-464* YPbPr* | 2 | None 300m (1000') |
* These units are capable of also transmitting audio; however this feature is not supported when used with a C2-1200/1250 unit.
*2 When using a 1T-CT-464 (Serial Numbers < 223846700100x) you will need to swap the Pb and Y connectors on the receiver to achieve a correct image.
6.3 Audio inputs and outputs
Certain models (C2-1200, C2-1250, C2-1350) support audio switching, simultaneous with video switching. This means that audio input 1 might switch at the same time as RGB1, audio input 2 with YC1, etc. Each audio input connector can be configured to be 'linked' to a particular video input connector, so that they switch together.
Once switched, the audio input connector is linked to the audio output connector with no audio processing or buffering taking place. The only processing that is performed, is 'click-less' operation.

On the back of audio-equipped units are 5 x 3-way connector blocks. These can be removed individually (with care), or can be left in-situ whilst connections are made (by releasing each terminal using a small screwdriver, and then by clamping it back down again once a new cable has been inserted).
The diagram above shows the 5 connector blocks (as viewed from the rear of the unit), each with Left, Ground and Right terminals.
7 INFRA-RED REMOTE CONTROL
Your unit is compatible with an optional infra-red remote control as shown below:
The transmit range of the remote control depends on many factors, but is designed to be fairly directional. Therefore you should always aim it directly towards your unit.
The IR remote control can be disabled in the System menu. This can be used in situations where multiple units respond to the same remote control or are located close to one another.
8 MENU LAYOUT AND SETTINGS ADJUSTMENT
From here on, we'll be looking at the menu structure employed in your unit and, more importantly, the individual menu items that allow you to take advantage of the power of the unit.
You'll be using the multi-directional switch and the on-screen display (OSD) to view the options and settings available to you. First press the multi-directional button in once to reveal the menu. Next, move the multi-directional switch left or right to see where you are in the menu. Go into a sub menu by pressing the multi-directional switch once. To exit a sub menu, scroll the multi-directional button to the end of the sub menu to reveal Exit. Push in the multi-directional button to exit the sub menu. To exit the on-screen display hold in the multi-directional button until the menu disappears.
You can edit a value in brackets ‘[ ]’ by pressing the multi-directional switch once (you’ll note that the brackets surrounding a particular parameter’s value will begin to flash). Change the value by moving the switch left or right. Then finalise your adjustment by pressing the multi-directional switch once more.
A few menu items have multiple parameters within an individual menu selection. In those cases, you can adjust one item at a time. To do this, move to the next parameter by moving the multi-directional button left or right, etc.
Adjust windows
H/V zoom pan % [10] 20
Or, you can use the up/down positions of the multi-directional switch to alter the value following the one in brackets. Therefore, in the example above, where “[10]20” is displayed in a menu item, the one in brackets is adjusted using the left and right positions, and the second number be can be altered using the up and down positions of the multi-directional switch.
Holding the multi-directional switch left, right, up or down for a short time will keep adjusting the relevant value, therefore allowing fast changes to a setting – which is very useful for positioning something on screen.
Pressing the multi-directional switch in for a few seconds stores all changes in memory. Unless you intentionally change it again later, the adjustment will remain even after power is removed from the unit.
Holding the SELECT button in for a few seconds stores all changes in memory. Unless you intentionally change it again later, the adjustment will remain even after power is removed from the unit. The High Level Menu Structure
Menus are arranged so that a particular general function has a menu name on the top line and beneath that either a sub-menu or one or more related individual settings are displayed.
In some cases the functionality is global – meaning it has an effect on the unit as a whole (such as changing the output resolution). In the majority of cases, the function is related to a specific operational area of the unit, detailed by the text in the top line.
There are two screens that appear before the Group Menus (sub-menus) are accessed.
CORIO2
TV One
The first is the ‘welcome’ display shown above indicating the model of the unit.
www.tvone.com
SW: 65. PT: 12, BT: 13
Moving to the next menu item displays the firmware information screen (the numbers on your unit will be different to those shown). The SW number refers to the version of firmware loaded into the unit, this can be upgraded from the support website.
The PT and BT numbers refer to Hardware version information and are of interest to the Technical Support Group should you ever need assistance.
At the end of all Group Menus will be an 'Exit' item. Simply select this to exit the existing menu structure and return to the previous one in the hierarchy.
8.1 Group Names and Descriptions
| Menu Group Name Group Description |
| Adjust outputs Controls output parameters |
| Adjust windows Controls characteristics of the scaling windows |
| Adjust keyers* Controls the keying ability of the unit |
| Adjust sources Controls signal source input parameters |
| Adjust resolutions Controls unit's input/output resolution table |
| System Controls global system parameters for the unit |
*Note that not all units have this menu item.
Note that the ‘Advanced menus’ menu item must be ‘On’ to activate certain menu items.
8.2 Items Associated with the Adjust outputs group
This menu group allows adjustments to be made that specifically affect the output of the unit, including output resolution and locking/overlaying onto a computer or video source.
800 x 600 60Hz
Lock mode
[Off] [RGB1]
This menu item allows the lock mode to be selected and the lock source to be defined. The top line of the display shows the current detected resolution of the selected lock source (RGB1 in this example). The lock mode can be either Off, Genlock or Lock & Mix, with the operation of these shown in the following table:
| Lock mode Description | |
| Off The output resolution of the Output is defined by the setting for Output Resolution and there will be no background source visible. | |
| Genlock The output video will be “Genlocked” to the selected lock source. The output signal will be synchronous to the input sync and adjustable but there will still be no lock source visible. | |
| Lock & Mix The output video will be locked to the selected source, the syncs will be locked (but with an additional internal video processing delay) and the background for the output will be that of the Lock source (unless foreground and background are swapped). | |
| Frm.lock* The frame rate of the output will be locked to the frame rate of the input. This can only work if the output resolution frame rate matches that of the lock source frame rate. ‘Frm.lock’ will flash until a highly stable lock has been achieved. |
*Only certain models support this.
In both Genlock and Lock & Mix modes the source selected for the lock input determines the resolution of the Output image. The output resolution for the entire image can be no different than the resolution of the lock source. All synchronization signals are re-generated within the unit so they may look slightly different when compared on an oscilloscope to the original source.
In Frame-lock mode, the output resolution is independent of the lock source, but the frame-rate must match that of the source (e.g. 1280x1024 60Hz can be frame-locked to 640x480 60Hz). Frame-lock is very useful for synchronizing a HD-SDI output (e.g. 1080i 59.94Hz) to a composite video source (e.g. NTSC), or for scaling one resolution to another while avoiding any potential frame-rate conversion artifacts.
'H/V shift' can be used to align the output to the input more accurately, but this may cause instability until the lock is re-acquired ('Frm.lock' will flash).
Before turning the Lock feature on, you first must select a valid Lock source. Some units may not have all Lock sources available, depending on hardware limitations – see Specifications for details of limitations on your unit.
If the Lock source you choose is not valid, then Genlock or Lock & Mix will be temporarily disabled, until the Lock source becomes valid again. When disabled, the resolution previously specified in 'Output res' becomes the output resolution.
1024 x 768 60Hz Output res.
[28]
Your unit can handle a very wide array of inputs and convert them all to a single output signal with defined characteristics. This output resolution will remain in place until changed or it may be overridden by the lock mode and source.
The top line of the display will show the current output resolution selected. Some units will have a limited number of output resolutions depending on their function (e.g. Down Converters are more limited than Video Scalers).
1024 x 768 60Hz HDCP (Active) On
HDCP is handled only on certain units with DVI outputs, so this menu may not appear on your own unit. HDCP is a 'High-bandwidth Digital Content Protection' system, which can ensure that a high definition video signal cannot be received by units not equipped with a HDCP receiver.
This menu lets you see the current status of the output and whether HDCP is supported or active, and also lets you turn off the output's HDCP encryption system. Note, however, that turning HDCP off at the output will also prevent HDCP-encrypted signals from being received by the unit – see the table below.
By default, HDCP on the output is turned On - so that if your attached DVI display is HDCP-compliant, then your output will be encrypted (regardless of whether the input to the scaler is encrypted). Note that you don't have to attach a display to the output of the scaler – another unit can be connected instead, in which case that unit is known as a 'repeater'.
Please also see the HDCP menu item in 'Adjust sources', as this controls availability of HDCP at the DVI input. The status message given in brackets has the following meaning:
| Status message | Description Effect | |
| No display There is no display attached (HOTPLUG is low). | Nothing will be output on the DVI connector. | |
| Unavailable The device attached is not capable of supporting HDCP. | As the DVI output cannot be HDCP encrypted, then a HDCP-encrypted source cannot be selected for scaling. | |
| Supported The device attached is capable of HDCP, but the output is not currently encrypted. | As the DVI output is not HDCP encrypted, then a HDCP-encrypted source cannot be selected for scaling. | |
| Active The device attached is capable of HDCP, and the output from the unit is encrypted. | As the DVI output is HDCP encrypted, then a HDCP-encrypted source can be selected for scaling. Note that no other output connector (SDI, CV, YC, YUV or RGBHV) will function – since they are not encrypted. | |
| Rep. supprt The repeater unit (e.g. scaler) attached is capable of HDCP, but the output is not currently encrypted. | As the DVI output is not HDCP encrypted, then a HDCP-encrypted source cannot be selected for scaling. | |
| Rep. active The repeater unit (e.g. scaler) attached is capable of HDCP, and the output from the unit is encrypted. | As the DVI output is HDCP encrypted, then a HDCP-encrypted source can be selected for scaling. Note that no other output connector (SDI, CV, YC, YUV or RGBHV) will function – since they are not encrypted. | |
| Adjust outputsOutput type [RGBHV] | |
| Adjust outputsAnlog= [RGBHV] Dig= RGBHV |
This menu may appear as either of the above – depending on whether the analog and digital outputs are controlled separately.
This menu item allows you to select the type of signal output your unit will provide. Types of output vary depending on the resolution selected and include various types of component signals YUV or tIYUV (tri-level YUV) and the full range of RGB type signals RGBHV, RGBS and RGsB (Sync on green).
Note that this value is remembered for each resolution – so you can set 1024x768 60Hz to RGBHV and 1280x720 60Hz to tIYUV and both will be remembered separately. This value is not affected by a Factory reset – but is reset by a firmware update.
| Adjust outputsOptimize for SDI | [On] |
This menu item is only available on certain units with an SDI output and when locking to a CV or YC input. An internal de-jitter circuit ensures that the SDI output has a low jitter over the full 10Hz to 100kHz range, even though the CV or YC input may have a high jitter. However, this is not always compatible with a CV/YC output where the colour sub-carrier should not be de-jittered and needs to follow a Lock source's input – hence it should be turned Off it the CV/YC outputs are going to be used.
Adjust outputs
Stand. [NTSC-M/PAL-BDGHI]
This menu item is only available when the Output resolution is set to PAL or NTSC. With this you can change the output type to the PAL or NTSC standard with the further option of changing the output to the additional PAL & NSTC standards such as PAL-M or PAL-N. SECAM is also available as an output on some units, provided the 'Output res' is set to PAL / 50Hz.
Adjust outputs
Luma/chr BW [Med] / [Med]
This menu item is only available on certain units when the Output resolution is set to PAL or NTSC. With this you can change the output filtering system to increase or decrease the image sharpness. In general, high sharpness can result in increased colour disturbance.
Adjust outputs
Back Y/U/V [16] [128] [128]
Sets the value of the fixed background color, which is present when PIP is used with no Lock source background displayed. This menu item is only available for units with overlay, keying and fading abilities.
Adjust outputs
Audio emb. [On] [DVI-U1]
For certain units with HDMI and/or SDI-compatible inputs and outputs, the audio can be de-embedded from the video signal and sent to a compatible output.
‘On’ enables this to happen, and allows the audio source to be selected. ‘WinA’ sets the audio source to follow that of the main window’s video source.
8.3 Items Associated with the Adjust windows group
This menu group allows adjustment to be made to window specific parameters such as the window source, its position, size and zoom level.
Window size adjustment can be performed in a number of different ways according to whether 'Aspect adjust' is set to Simple, Advanced or Pixel. The main part of this text assumes Simple mode – see later for a detailed description of the other modes.
Adjust windows
Window to adjust [A]
This menu item only appears on units with multiple windows or PIPs. It is used to select which one you want to modify. Alternatively, use one of the dedicated buttons on the front panel to choose the window to adjust.
NTSC / 60Hz
Source
[ YC1]
The source display screen allows the input source for the currently selected window to be changed. The top line of the display shows the detected characteristics of the signal. Valid Input sources match those available on the front of the unit.
Certain units do not have full flexibility of Window source and Lock source when Genlock or Lock & Mix are active (in the Adjust outputs menu group). See the Specifications for your unit to see if any limitations are present.
Adjust windows
Window enable
[ On]
Available on certain units only, this quickly enables or disables the window being adjusted.
Adjust windows
Zoom level %
[100]
Changing this option, sets the amount of picture magnification you wish to use for the window Source. You are provided with the options to zoom the image from 100% to 1000% (10x zoom).
Adjust windows
H/V zoom pan % [50] [50]
Once an image has been ‘zoomed’, this control allows the image to be positioned within the window so that any portion can be seen, not just the middle.
Adjust windows
Image freeze
[Off]
This menu item allows the image to be frozen or unfrozen – thus keeping a single image on screen indefinitely. Note that images are not stored when power is removed from the unit.
Adjust windows
H/V crop % [0] 0
This allows the scaled image to be cropped at the top/bottom edges, or at the sides. Typically, this is used when performing a picture-in-picture (PIP) function (only available on certain models), where the incoming video signal has a letterbox or pillarbox size (i.e. it has black areas at the top/bottom or sides).
By adjusting the H/V values, you can crop out the black areas to correct the size on the final output screen. Note that it does not change the shape or aspect ratio of the image – but just removes the parts of the image that are not required.
Adjust windows
H/V out shift
[0][0]
This positions the selected Window horizontally and vertically on the monitor. This should only be used for 'fine tuning' and should not normally require adjustment – use the Shrink H/V adjustment when your image is less than 100% Shrink value.
Adjust windows
Shrink level%
[50][On]
Shrink Level determines the percentage of the monitor's total available screen space that the selected Window image occupies. Adjustment is provided for a reduction down to 10% of the overall output size. In most cases, this feature is used for picture-in-picture (PIP) when a background image is being used (for units with overlay abilities).
Note that some units do not have the [On] entry – this is only for units with a PIP button on the front, with turns this entry On and Off. On these units, this feature is 'Off' by default, so that the full image size of 100% is used. Shrink level will need to be turned On before any change to this value has an effect.
Adjust windows
H/V position %
[100] [50]
This menu option determines the position of the shrunken image on the monitor screen. This will move an image that is less than the full screen size left/right or up/down within the monitor's available screen space. It will not let you move the image off the screen, so certain values will appear to have no effect (unless you use a very low Shrink value like 10%).
Adjust windows
Aspect change
[Normal]
This item provides a simple way of changing the output screen aspect ratio, to suit the incoming video signal and final output display size. Use the zoom/shrink functions for occasions when the aspect ratio is an odd format.
Adjust windows
Aspect adjust
[Simple]
See later section for further details on this item.
Adjust windows
Temporal interp.
[Off]
This is a feature only present in advanced units only. It greatly improves the method of frame-rate conversion, by allowing the unit to merge frames together during the process.
When 'Off', the unit will use frame-repetition when converting 50Hz to 60Hz (i.e. it has to duplicate every 5th frame), or frame-dropping when converting 60Hz to 50Hz (i.e. it has to drop every 6th frame). When 'On', smooth blending is applied so that frames are not lost, but blended together at the appropriate times.
Adjust windows Flicker Reduction
[Low]
The Flicker Reduction menu item will only appear if you have selected a low resolution interlaced output such as PAL or NTSC. If you are using CV or YC outputs, this adjustment may be of interest, particularly when you have line drawings or similar fine detail. You can choose from four possible Flicker Reduction settings. You should use as little Flicker Reduction as possible because the Vertical detail will be softened at the highest setting.
| Flicker mode Function |
| Off Disables flicker reduction (sharpest mode). |
| Low Suitable for most input sources. |
| Med. Enough for most situations such as thin line drawings |
| High Highest amount of flicker reduction. Will cause loss of vertical detail in some images. |
Adjust windows Image smoothing
[Auto]
Image smoothing reduces the jagged-edges sometimes seen within an output image by softening it. It typically improves the quality of a scaled image greatly. There are four possible settings for this adjustment: "Off", "Med.", "High", and "Auto". The "Auto" setting is generally thought to be most desirable and will vary the smoothing process according to the amount of zoom taking place.
Adjust windows Image flip
[Off]
Occasionally, it's necessary to cause the output image to be flipped Vertically, Horizontally or both – most commonly when a video projector is ceiling-mounted, or for special effects.
Adjust windows Show source label
[On]
Units that support source labeling have this menu item available, which allows the label to be turned on or off on a window-by-window basis.
Adjust windows
Audio bars
[4]
Certain units can display audio bar measurements and this menu item displays how many stereo-bars are shown. A maximum of 4 stereo bars (8 bars in total, with left-right pairs next to each other) can be shown. Audio channels are always numbered from left to right, balanced to display bars on both sides of the each. A setting of 0 disables the audio bars from being shown.
Adjust windows
Max fade level %
[100]
This Menu item fades the selected layer, and is only available on models with overlay abilities. Adjustment range is from solid to fully transparent.
Note: This menu item only appears on multi-channel scalers:
Adjust Windows
Layer priority abABZ
[3]
This adjustment selects the order of the window layers. Layers are shown for 'a' and 'b' logo screens, Window 'A', Window 'B' and 'Z' is the Lock Source. The default condition is shown. The number shown is the current layer of the active window, when you adjust the layer number the layer stack indicator 'abABZ' will change to allow visualization of the layer stack. Note that layer 6 the Background Color is not shown as its layer position can not be altered – it will always be the background.
8.3.1 Extended scaling controls
The ‘Aspect adjust’ parameter is used to change the way that scaling of windows is controlled. By default it is set to ‘Simple’ which allows basic control of the window zoom and shrink sizes and positions – enough for simple tasks.
In ‘Advanced’ mode, it allows the horizontal (H) and vertical (V) components of the Zoom and Shrink functions to be adjusted independently, thus allowing custom aspect ratios to be created, or to convert from one aspect ratio to another.
In ‘Pixel’ mode, the user has direct access to pixel and line-accurate scaling functions. This lets the user specify the exact co-ordinates and size of the source image (within the video source), and the position and size of where this is placed in the output video signal.
The table below summarizes the different menu items in the different modes – the 'Simple' items have already been described earlier in this section, so only the 'Advanced' and 'Pixel' ones that are different (highlighted in bold) will be detailed here.
| Simple Advanced Pixel | ||
| Zoom level % [100] Zoom H/V [100]100 1.333:1 In [0],0 640,480 | ||
| H/V zoom pan% [50] 50 H/V zoom pan% [50] 50 Out [0],0 640,480 | ||
| H/V crop % [0] 0 H/V crop % [0] 0 | ||
| Shrink level % [50] Off ShrnkH/V [50] 50 1.333:1 | ||
| H/V position % [50] 50 H/V position % [50] 50 | ||
8.3.2 'Aspect adjust' = 'Advanced'
Adjust windows H/V zoom % [100] [100]1.333:1
This item allows the independent setting of the horizontal and vertical zoom values. The third number (1.333 in the example) is the Aspect Ratio resulting from the adjustments, which is automatically calculated for you based on the incoming resolution and the H & V Zoom values.
Most resolutions are 4:3 ratio, thus the third number will be 1.333 (4 divided by 3). Another common aspect ratio is 16:9 (16 divided by 9 = 1.777). PAL and NTSC inputs are physically 4:3 on your video monitor, but their actual pixel/line ratios are different and so will not display as 1.333.
Adjust windows Shrink H/V % [100] [100] 1.333
This item allows the setting of different Horizontal and Vertical 'shrink' sizes. The third number (1.333 in the example) is the Aspect Ratio resulting from the adjustments, which is automatically calculated for you based on the output resolution (the actual pixels & lines, not your physical screen size) and the H & V Shrink values.
Most resolutions are 4:3 ratio, thus the third number will be 1.333 (4 divided by 3). Another common aspect ratio is 16:9 (16 divided by 9 = 1.777). Therefore, to convert your 4:3 output into a 16:9 output, reduce the vertical (V) Shrink value to 75% and this will simulate a 16:9 output. PAL and NTSC inputs are physically 4:3 on your video monitor, but their actual pixel/line ratios are different and so will not display as 1.333.
8.3.3 'Aspect adjust' = 'Pixel'
Adjust windows In [300], 150 750, 400
Adjust windows Out [50], 50 250, 300
These menu items work together to specify the exact co-ordinates and size of the source image (within the video source) and the position and size of where this is placed in the output video signal – in other words the 'In' and 'Out' positions and sizes.
The diagram below should help to clarify the function of these values:
![graph TD A["IN"] -->|768| B["OUT"] B -->|1024| C["0"] style A fill:#f9f,stroke:#333 style B fill:#ccf,stroke:#333 style C fill:#dfd,stroke:#333](/content/2026/05/999607/images/782a9fb76982a21d2009b87385294390b0f7a336c3fcfd185e9769ebb66daeae.jpg)
In the example above, 'In' has been set to 300,150 as its top-left source co-ordinate, with a size of 750,400. 'Out' has been set to 50,50 (i.e. close to the top left) with a size of 250,300.
The scaler will then ensure that the whole of the source (of size 750 by 400) is scaled to the required output (of size 250 x 300).
8.4 Items Associated with the Adjust keyers group
Please note that not all units have this sub-menu – it is only present on units with overlaying abilities.
Towards the end of this manual you will find a section titled 'COMMON OPERATIONS' – this gives a step-by-step guide to keying out a particular color.
Adjust keyers Keyer enable
[Off]
This menu item turns keying On or Off for the current foreground. A keyed image is in essence one image superimposed over another – such that portions of the top image are made transparent (keyed out), so that the background image can show through. The following settings allow you to vary the colour(s) that are keyed out.
Adjust keyers
Swap fore/backgrnd
[Off]
This menu item is only present on single-channel scalers – dual and quad-channel scalers have the layer priority set within the 'Adjust Windows' menu.
This menu item allows you to swap the foreground and background images when Lock mode is set to Lock & Mix. It will have no effect in any other mode (since no background is present).
Normally, your foreground is the input (window) source and your background is the lock source. This then allows you to superimpose any graphics or video input on top of the lock source by keying out a certain color or range of colors in the input source. Swapping them means that the input source moves to the background and the lock source is now in front of it. Thus you are now keying out the lock source colors to reveal the input source behind it.
Note that this is different to simply swapping over the input and lock sources as that would affect the final output resolution – see examples below:
| Input source | Lock source | Swap F | foreground (keyed) | Background (non-keyed) | Output resolution |
| XGA NT | SC Off XG | A NTSC | NTSC | ||
| XGA NT | SC On NT | SC XGA | NTSC | ||
| NTSC XGA | Off NT | SC XGA | XGA | ||
| NTSC XGA | On XGA | A NTSC | XGA |
(XGA is 1024x768)
You will see that the Swap between foreground and background has no effect on the output resolution as this is always set by the Lock source.
Adjust keyers
Y Key min/max
[0][32]
The Min/Max parameters are used to select what range of Y (luminance/grey-scale) values are made transparent within the selected window/lock source. In order to key out part of an image, start with the max value and increase it until the required lighter parts within the window/lock source disappear. Then adjust the min level to bring back any darker parts of the image.
Adjust keyers
Y Key softness
[0]
The Y Key softness option removes noise from the keyed image, generally at the edges. Adjust as required to make the edges of the key as sharp or as soft as desired. The noise is where the analog to digital process (A/D conversion) may not sample a 50% brightness as being exactly 50% i.e. sometimes 49% and sometimes 51%. Increasing the softness value will broaden the range of keyed colors so that the keying of images varies depending on how close a color is to the keyed-out range.
Adjust keyers
Y Key invert
[Off]
The Y Key invert changes the keying characteristics with respect to what colors of the foreground image you wish to 'key out'.
Setting it to Off will cause the colour range that's defined to be removed - remove the desired colors. Setting it to On will cause the colour range that's defined to be kept - key out all other colors.
The descriptions above behave identically on the remaining U Key Invert & V Key Invert component versions. However they are directed at the U/B-Y (blue) colour component and V/R-Y (red) colour components respectively. Adjustment and effects are the same as explained above for Y Key Invert (brightness/grey-scale).
8.5 Edge Blend items within the Adjust keyers group
Please also see the section titled 'EDGE BLENDING SETUP' later in this manual.
Adjust keyers
Edge blend
[None]
This menu item controls which of the 4 edges are blending into the background. In general, only the left or right are blending, but the unit allows you to control the edge blending for any number of edges.
If any edges are set (e.g. [L ] for left) then Keying is no longer available and extra menu items will appear as follows:
Adjust keyers
E.blnd guides
[Off]
This menu item allows you change whether the red and green edge blending guides will appear. You can have them permanently Off, permanently On, or set to Auto (where they will only appear when you are in the Adjust keyers menu).
Adjust keyers
E.blnd size
[50]×[50]
This controls the blend width and height respectively. Left and Right blend sizes are adjusted together by the first number, and Top and Bottom blend sizes are adjusted together by the second number.
Adjust keyers
E.blnd gam.
[1.00] × [1.00]
This controls the gamma for the blend width and height respectively. Left and Right blend gamma values are adjusted together by the first number, and Top and Bottom blend gamma values are adjusted together by the second number.
The gamma values affect the linearity of the blended edges, allowing for the fact that projectors do not normally output a picture whose brightness is directly proportional
to the voltage within the video signal. These values are best adjusted once any overlapping images are aligned with each other
Adjust keyers Eb comp cent/side [0] [0]
This controls a ‘compensation’ value that sets the minimum brightness of the centre and side areas during edge-blending. It is used to compensate for the fact that projectors cannot generally output a purely black signal – and hence the overlap area would normally be brighter as a result. Increasing the centre area’s value will compensate for this.
For 2x2 (or higher) setups, the side value can also be adjusted to correct for corner brightness errors
8.6 Items Associated with the Adjust sources group
The ‘Adjust Sources’ menu group accesses the parameters associated with the processing amplifiers used for each input (RGB, CV, YC, etc.). They allow you to fine-tune an incoming signal to optimize its color, brightness or even sharpness.
Not all settings are available for all input types, and not all input types listed here may be available on your unit. Also note that many of these adjustments may not show without ‘Advanced menus’ set to On.
It is recommended that you Store your settings once you're happy with them in readiness for future use.
Source: RGB1 Source to adj [RGB1]
This menu item selects the input connection for which you want to make adjustments to. As in the image above, changes will only be made to the source connected to RGB1. Once the selection has been made, all changes made using the following operating parameters will only apply to the selected input.
Selection of a CV/YC source will reveal different menu items that allow adjustments beyond those used for RGB sources. The menu discussions that follow relate first to RGB sources, then to CV / YC type sources.
8.6.1 Menu items common to all inputs
Source: RGB1 Aspect correct [ Fill]
This menu item will be used to correct the aspect ratio of the video source when converted into the final output resolution. The following table details what happens in the available modes:
| Setting Result | |
| Fill (default) | The source is stretched to fill the output. |
| Aspect The source's aspect ratio is maintained on the output. | |
| H-fit The source is stretched to fill the horizontal dimension of the output, with the vertical dimension stretched by the same amount (and possibly clipped). | |
| V-fit The source is stretched to fill the vertical dimension of the output, with the horizontal dimension stretched by the same amount (and possibly clipped). | |
| 1:1 Each source pixel is represented by a single output pixel – no scaling will be performed. If the input resolution is higher than the output, then only part of the source will be seen. If the input resolution is lower than the output, then a black border will be present. | |
Source: RGB1
TL pos. adj. [0][0]
This menu item allows manual positioning of the Top and Left portion of the image. It is used to ensure that the input signal is captured correctly, eliminating any black borders. These settings are often used to correct the position of a PC signal on an input, or to eliminate any undesired noise at the top or bottom of a PAL or NTSC video source.
Source: RGB1
BR size adj. [0][0]
This menu item allows manual positioning of the Bottom and Right portion of the image. These settings are often used to correct the position of a PC signal on an input, or to eliminate any undesired noise at the top or bottom of a PAL or NTSC video source.
Source: RGB1
Audio input source [1]
If your unit has an internal audio switcher / selector, this menu item selects the desired Audio input for use with the active video source, allowing an audio-follow-video function.
Source: RGB1
OPTION audio source [1]
If an external audio switcher is connected via the OPTION bus, then this menu item selects the desired Audio input for use with the active video source, allowing an audio-follow-video function.
In most situations, the Audio input values would be different for each video source – so that when the first video source is selected, so is the first audio source (this is called 'audio follow video'). The second video source then selects the second audio source, etc. However, there is nothing to prevent all Audio input values being set to the same value, for 'audio breakaway'.
Source: RGB1
Audio Vol [ 1] Bal [ 0]
This menu item adjusts the audio volume and balance for the selected audio channel. This is only functional for certain units when an optional Audio Switcher is attached.

On source loss [Blue]
(This has replaced 'De-glitch' used on previous firmware versions.)
This option is used to tell the unit what to do if the video source is lost or becomes unstable. Options are:
| Option Description |
| Show Shows all picture break-up and instabilities. |
| Freeze Freezes the latest frame – un-freezes as soon as the source becomes stable again. |
| Blue (default) Turns the window blue, to represent source loss. |
| Black Turns the window black. |
| Remove Removes the window, thus showing any background (e.g. a Lock source). This is useful for MIX & PIP scenarios on units with overlay abilities. |
If you have a very unstable input, such as a video tape player with a poor (jumping) output signal, you may wish to turn the setting to 'Show'.

De-int [M.comp med]
An interlaced input consists of two fields separated in time. Both fields are required in order to make up the full resolution input image, but since they are sent one after the other, a moving image will have “motion artifacts” if the two fields are simply combined together. The most common artifact is a blurring at the point of maximum movement within an image. Your unit provides some tools to minimize the effects of de-interlacing of an image.
The following options are available for this menu item:
| Mode Function | |
| Normal/weave | The two interlaced fields are simply combined/weaved together. This will often show artifacts on moving images, but can be used when the input is known to be still. |
| Auto Automatically selects Film 3:2 or Medium Range Motion Compensation (M. Comp Med.) depending on whether Film Mode is detected or not. | |
| Film 3:2 Enables 3:2 pull down conversion of the incoming NTSC video. (This option should not be used if the source is not NTSC video). | |
| M. Comp Low M. Comp Med. M. Comp High | Enables Pixel Adaptive Motion Compensation. Three levels are available with ‘Low’ providing the least compensation for Motion and ‘High’ providing the most compensation. |
| Frame/bob The two fields are shown consecutively. | |
Source : RGB1 Diagonal interp. [Off]
This menu item allows the user to specify whether the source has diagonal interpolation applied to it when de-interlacing occurs. This reduces 'jagged' artifacts on moving images, however is not suitable for noisy sources where the noise could be mis-interpreted as a diagonal or sloping element of the picture.
Source : RGB1 Noise reduction [Off]
This menu item allows the user to specify whether the source has noise reduction applied to it. This is performed by averaging the video signal over a number of fields – but ignoring areas where motion has occurred. If motion blurring is seen, it is recommended to turn this setting off.
8.6.2 DVI Source Menu Items
Source: DVI1 HDCP [Inactive] [Off]
HDCP is supported on certain units only - and only on the DVI input connector. This menu item lets you change whether HDCP is active on this particular DVI input.
If turned 'Off', then a source that requires HDCP encryption will not send a video signal to your unit.
If turned 'On', and a HDCP-compliant display or device is attached to your unit's DVI output, then HDCP encrypted sources can be used.
The following table summarizes the message given in brackets:
| Status message | Description Effect | |
| Inactive HDCP is not active at the DVI connector. | HDCP-encrypted material cannot be received by the unit. | |
| Active HDCP is active at the DVI connector. | HDCP-encrypted material can be received by the unit, but only if a HDCP-compliant display or device is attached to the unit's output. | |
See ‘Adjust outputs’ for a description of how the HDCP system works on your scaler.
Source: DVI1
Display emul. EDID [DVI]
This feature is only present on certain units – it is used with the next menu item to form a simple 'EDID Manager'.
EDID is an information packet retrieved by a PC graphic card over a DVI link from a monitor which tells the graphic card which resolutions the display supports. In the case of your unit, it tells the graphic card what resolutions are compatible with it – by emulating a display.
The above menu lets the user select which of 8 EDID data blocks are 'shown' to a PC or other DVI/HDMI source. (It does not affect any other input.) Note that some graphic cards will usually only read the EDID data when the cable is first connected, or on power-up.
The 8 EDID blocks are as follows:
| EDID Usage | |
| Mem1 | User-definable – see ‘EDID capture’ |
| Mem2 | |
| Mem3 | |
| Mem4 | |
| Mem5 | |
| Mem6* | |
| HDMI* | Default HDMI EDID data for your unit |
| DVI | Default DVI EDID data for your unit |
| Mon | The attached monitor’s EDID data |
*Your unit will have either Mem6 or HDMI, but not both.
If you change this value, you'll need to store your settings and then re-boot the CORIO2 unit at least once to ensure that the source sees that the EDID data has changed.
It should also be noted that some graphic cards will require your PC to be re-booted before they see that a change has occurred.
If your unit allows 'HDMI' to be selected, this can also enable certain audio features depending on the abilities of your unit.
Source: DVI1
EDID capture [1] Grab
This menu provides a simple way of capturing EDID data from an attached DVI or HDMI monitor and storing it in one of the user-definable EDID memory data blocks (Mem1 to Mem6) – see previous menu.
To capture a different display's EDID, perform the following:
- Connect that display to the DVI output of the CORIO2 unit - the CORIO2 unit will then read it automatically and store it in the 'Mon' EDID entry.
- Select which EDID memory (Mem1 to Mem6) to copy this information to.
- Select 'Grab' and click on it - this will copy the current monitor's information to that EDID memory.
- Change 'EDID to use' to that memory location (Mem1 to Mem6).
- Store your unit's settings (see earlier in this manual on how to do this).
- Re-boot (turn off and on again) the CORIO2 unit to ensure that the graphic card uses this new EDID data (you may need to re-boot your computer as well).
Using the above, up to 6 custom EDID settings can be stored in the CORIO2 unit, ready for recall later. This is useful to simulate another display being attached to a graphic card.
8.6.3 RGB Source Menu Items
Source: RGB1
Autoset status [Inactive]
Once the Autoset sense setting has been made, this menu item is accessed and activated. The Autoset sense utility will then correct the pixel phase and then position the Top Left portion of the image and the Bottom Right portion of the image. Once complete it then resume inactive status.
Source: RGB1
Input pixel phase [16]
Since an image pixel is a very small element of the total image, it's possible for your unit's Analog to Digital converters to wrongly sample the picture on the edge of each pixel thereby losing image resolution and creating image noise. The Input pixel phase adjustment allows you to change the position (from 0 to 31) where the pixels are sampled, relative to the horizontal sync signal.
To make this adjustment, select an RGB source and then provide an image from that source with fine detail, preferably with very sharp vertical lines. Adjust this value until you see the sharpest image. Alternately, adjust this value to give the worst (noisiest/softest) image, and then add or subtract 16 to get the optimum value.
Note that the AUTOSET function (for RGB inputs only) will attempt to automatically work out the best value for this setting.
Source: RGB1
RGB input type
[RGBHV]
There are several types of signals that are called RGB signals as a generic term. Each has slightly different characteristics that set it apart from similar RGB signals – such as how the synchronization signal is sent. This menu item lets you set the input type to use.
Available options let you select whether the input is standard RGB or YUV (including YPbPr signals with a tri-level sync). For some units, it also allows selection of breakout BNC connectors to be used instead of the normal connector (signified by B- in front of the signal type).
Source: RGB1
RGB contr. [100] [100] [100]
This menu item lets you adjust the individual RGB or YUV/YPbPr signals, in case one component is at a different contrast to other, or if they all need to be boosted or lowered.
8.6.4 CV & YC Source Menu Items
Of the above Source Menu items, the Autoset sense and Autoset status functions, RGB type and Pixel phase are specific to RGB signals only. The rest of the Source menu items function with RGB, CV or YC type signals. In addition, there are four additional Menu items that are only used with CV or YC type signals and these are explained below:
Source: YC1
Bright [100]
Contrast [100]
Adjust the Brightness and Contrast of the image to your requirement.
Source: YC1
Satur [100]
Hue [0]
Saturation is the amount of color present in the image. Hue is the color “tint” parameter and the adjustment range is +90 degrees through to -90 degrees with 0 being the default.
Source: YC1
Sharpness
[0]
Within limits, you can enhance or soften the appearance of detail within an image. The Sharpness values go both negative and positive, with 0 being the default. Note that over-enhancing an image has the side effect of making it appear to be noisy and under-enhancing an image gives the appearance of poor video quality.
Source: YC1
Luma delay
[0]
On occasion, a video source will have the color portion of the signal offset from the luminance portion. If you've ever seen a poor quality comic book that has the outline of the cartoon character's head in one place on the page but the flesh tones for the head offset slightly, you are seeing the print equivalent of Luminance to Chrominance Phase Delay.
Fortunately, your unit provides a way for you to make the two signals occur at the same time on the selected image. The adjustment range provides both positive and negative levels of delay with 0 being the default.
8.6.5 Still Image Store / Testcard Source Menu Items
Source : TC1 Testcard [ 0
This item is only available for units supporting Still Image Stores (SIS) or Testcards (TC) – which are the same thing, but may be named differently depending on your unit.
Used to select the image from memory to use as a source for the SIS / TC source currently selected. Dedicated software can be used to upload user-defined images – see our website.
8.7 Items associated with the Adjust transitions group
Please note that not all units have this sub-menu – it is only available on some units with overlay and keying abilities.
Transitions control how your unit responds when a source is changed. Fades between sources, as well as wipes and cuts, are possible. The amount of time taken by a transition is controllable from instant transition (a 'cut') to several minutes.
Adjust transitions
Transition
[Fade]
This first adjustment controls the type of transition desired: 'Cut', 'Fade', 'Wipe' or 'Push'.
If you select 'Cut' or 'Fade', the only remaining menu items will be 'Switching Fade Time' and 'Exit'. Selecting 'Wipe' or 'Push' exposes additional parameters.
| Adjust transitionsSwitching fade time | [ .5] |
This parameter controls how long a transition from one input to another takes. The value can be 0 (a cut) or several minutes - adjustable in 1/10th second increments.
| Adjust transitions | |
| Wipe type | [Left -> Right] |
If you selected 'Wipe' or 'Push' for the transition type, then you will be able to specify the 'movement direction' of the transition that you want. Both 'Wipe' and 'Push' support: Left to Right, Right to Left, Up/Down (Top to Bottom), Down/Up (Bottom to Top). 'Wipe' also supports: Diagonal and Diamond effect.
| Adjust transitions | |
| Wipe size | [100] |
Wipe Size sets the ‘granularity’ of the ‘Wipe’ effect and so is only shown when ‘Wipe’ is the transition type. The smaller the number, the more elements there are to the wipe. To clarify by example, if you select the Diamond wipe effect and set a small number into the Wipe Size parameter, you will have a large number of Diamonds present in the transition. On the other hand, a large number loaded into the parameter will result in only one or two diamonds being present during the transition.
8.8 Items associated with the Adjust resolutions group
The Adjust Resolutions Menu Group only appears when the Advanced Menus function is turned on within the System Menu Group. To turn it on, go to the System Menu Group and then proceed to the item that says “Advanced Menus”. Turn the
function 'On', exit the Systems menu and return to this menu structure.
The Resolution Database is used by your unit to identify any incoming video signal and is also used to create an output resolution. It is therefore a very important part of the unit's infrastructure.
Important Cautionary Information
DO NOT ADJUST THESE ITEMS UNLESS YOU'RE CERTAIN YOU KNOW WHAT YOU'RE DOING! THE ONLY METHOD TO UNDO CERTAIN CHANGES IS TO UPDATE THE FIRMWARE.
TRY USING THE AUTOSET, SHRINK, SHRINK POS, TL & BR ADJUSTMENTS FIRST.
Making adjustments here risks creating a non-standard resolution that is not displayable on a monitor. The resolutions and values within the database are industry standards and should not normally be altered by the user. That said, there might be times when it is necessary to create a custom resolution with specific parameters. If circumstances require you to make such a change, please read the following specific notes:
- Any changes made to this database take effect instantly and are also stored immediately in non-volatile memory.
- Since this database is used for both input and output image processing, altering a resolution that is used for both (e.g. 1024x768 input and 1024x768 output) may give undesired effects.
800 x 600 60 Hz
Image to adjust [17]
Change the value to select resolution you want to alter.
Typically, the image number currently being used for input or output would be already be selected otherwise immediate feedback to your changes will not be available via your monitor.
800 x 600 60 Hz
Interlaced [Off]
This adjustment specifies whether the image is interlaced or progressive scan. It toggles simply On or Off, so there are no flashing brackets.
800 x 600 60 Hz
H.freq.crse [37.879] kHz
Course Frequency Adjust
The H freq.crse (Horizontal Sync Frequency - Course) adjustment provides the option for changing the Horizontal Sync timing Frequency in 100 Hz steps.
800 x 600 60 Hz
H.freq.fine [37.879] kHz
Fine Frequency Adjust
The H.freq.fine (Horizontal Sync Frequency) adjustment provides the option for changing the Horizontal Sync timing Frequency in 1 Hz steps. Use this option to fine tune after using the course adjust.
Please note that the internal sync generator may be unable to generate the exact frequency you want.
800 x 600 60 Hz
Clks/I [1056] = 40.000MHz
This option changes the total number of image pixels on one line of monitor video including the Horizontal sync pulse and blanking time. This is normally in a multiple of 8. It is very important to get this value correct, or many digital display devices, such as TFT monitors, will display an image with an odd moiré effect – such as soft vertical bands spread evenly across the image.
800 x 600 60 Hz
Lines/f [628] = 60.317 Hz
This menu controls the total number of lines of video present in the image which includes the vertical Sync pulse, the blanking period and the active video. Changing this option affects the final vertical sync frequency.
800 x 600 60 Hz
H/V active [800] × 600
A video frame includes both the active area, the portion of the image normally containing useful visual information, and a resolution value for a given display standard which only expresses the number of pixels visible in an image. The well-known 800 x 600 computer resolution standard simply means that there are 800 pixels/line visible horizontally and there are 600 lines visible vertically.
This item provides a way to change the number of active pixels and lines.
800 x 600 60 Hz
H/V Start [88] × 23
There is a period of time between the end of the Horizontal Sync pulse and the start of Active Video. This portion of the waveform signal is called the “Back Porch”, a term originating with the television broadcasting industry and its RS-170A specification. In practice, this will control where the video image starts on the left side of the monitor without changing the width of the sync pulse itself (another way to control where the image area starts). The two parameters control where the back porch is positioned and they interact to a degree.
By adjusting these parameters, you control the start of the back porch (with respect to the trailing edge of Horizontal Sync) and also its width. The place where the Back Porch begins with respect to the Horizontal Sync pulse and the width of the Back Porch have a direct bearing on where the active (visible) portion of the image begins. Do not attempt this adjustment without monitoring the results with an oscilloscope.
800 x 600 60 Hz
H/V Sync
[128]×4
There are standards for all current computer and broadcast resolutions that specify the correct width of both Vertical and Horizontal synchronizing pulses.
If you are creating a special, non-standard resolution, you may wish to adjust the pulse width to fit your new requirements. The H/V Sync screen is where that is accomplished.
Like the H/V Start adjustment, you must use an oscilloscope when making these adjustments so that you know exactly how many milliseconds or microseconds of pulse width you have created. The numbers shown are relative numbers and not an actual time measurement.
800 x 600 60 Hz
Sync polarity
Sync can be either negative polarity or positive polarity. To further complicate things, it is possible that you may want to make the Horizontal Sync polarity different from the Vertical Polarity. This control allows you to make that change. You have four possible selections:
+ H + V - H + V + H - V - H - V
8.9 Items Associated with the System group
The final Sub Menu is for adjustments of System parameters. The “System” in this case means the unit’s functions that are generally unrelated to individual inputs, outputs or any of the various production features.
System
SW: 16,
PT: 12,
BT: 13
This screen is an informational screen. Should you require technical assistance with your unit, the technical support personnel may request that you read the contents of this screen to them during the support call.
The first section, "SW", is the version of the software that is installed on your unit. You can update software via the User Support web site (procedure to be described later in this manual) and the updates are currently free of charge. "PT" refers to Product Type and "BT" means Board Type. Both of these are hardware designators and cannot be changed by the user however both designators are important to support personnel.
System
SW date: 2006-7-11
This is an information page showing when the currently installed software was released. The information is useful to the user as he or she compares the date to the website information describing the current software release.
Normally, the user will examine the added features of each new software release and determine if an update is worth doing in their particular operation. The greater period of time between the current date, and the date shown for the currently installed software, the greater the likelihood that there are useful changes and improvements present in the new release.
System
TAC# 27-AA-1C-93-F8-33
The TAC number is a unique identifier for the unit and is for use with the PPF value below.
System
PPF# 1A-67-2B-9D-50-4F
The PPF number is for units that support the 'Pay Per Feature' system. Extra features in the unit (such as Mix and Key) may be activated using this menu tiem by entering in the correct numbers and re-starting the unit.
System
Push to store
This screen provides a quick and easy way to store all current operating parameters. The unit will remember the set up you are currently using at the time of data storage and also when you next apply power. To store the current settings, press and release the control button.
System
Autoset sense [Medium]
In order for Autoset to work properly, it needs a sufficiently bright full-screen image to examine. The sense level lets you change the brightness threshold for detection of the screen edge between Low, Medium, High and V.high. Medium is the default level, which is recommended for normal use (Windows-type images, etc.)
System
OSD on power up [On]
This parameter controls whether the ‘welcome’ screen is displayed or not on power up for units with an on-screen display – it can be disabled as required. This is useful when a unit is installed as part of an overall system.
System
LED brightness % [90]
This parameter is available on certain units and controls how bright the LEDs on the front panel appear.
System
LCD backlight [On]
This parameter is available on certain units and allows the LCD backlight to be turned on and off.
System
LCD contrast [200]
This parameter is available on certain units and allows the LCD contrast (viewing angle) to be altered.
System
LED brightness % [90]
This parameter is available on certain units and controls how bright the LEDs on the front panel appear.
System
Serial type [RS-232]
This menu item controls the type of serial port in use on certain units (not all units support this feature). Options available are RS-232, RS-422 and RS-485. The default is RS-232.
System
RS232 baud rate [57600]
This menu item allows the adjustment of the serial baud rate used for RS-232 communications. The rate can be adjusted to 9600, 19200, 28800, 33600, 38800, 57600 and 115200. (This adjustment is provided for those instances where you wish to use the RS-232 control system for your own purposes.) The default baud rate is 57600.
System
Buzzer
[ On]
The screen labeled 'Buzzer' is actually the control for turning the "Beep" "On" or "Off". Normally this is left in the "On" position to provide positive feedback that your data entries and parameter changes have been accepted.
System
CC-300 A/B bus mode
[Off]
This menu item changes the function of an attached CC-300 CORIOconsole unit. When set to 'On' any 'Take' will result in the A & B windows ('buses') being swapped at the end of the Take – so that another 'Take' will put them back to as they were before. (Note that not all units support the CC-300.)
System
Resolutions
88
This screen is an informational screen showing the total number of the defined resolutions in the resolution database. Future firmware releases may increase the total number of resolutions defined in the database.
System
Logos / T-cards
1 / 4
If your units supports Logos or Still Images / Testcards then this screen will display how many are present in the memory of the units.
System
Power cycles
41
Power Cycles refers to how many times the unit has been powered since it left the factory. This is an informational screen. No action is taken regardless of the value shown here, however some users have an equipment cleaning or specification audit procedure and this information may be useful to those users.
System
Firmware updates
11
Indicates the total number of times the firmware has been changed over the life of the unit. It is quite possible for this to be more than 1, as a unit undergoes numerous tests during production.
System
Hours in Use
877
This is another informational display for usage audit purposes.
System
Temp.C
30 33 43 45
Certain units have built-in temperature sensors, and if yours has such a feature then the above menu item will appear. If the ambient temperature of the internal components becomes excessively high or low, the unit will shut down to prevent harm. This display shows the current value of the ambient temperature at four locations within the case and can be an early predictor of a shutdown before the shutdown actually occurs.
Should you experience problems with your unit, Technical Support may request that you give details of these values.
System
Fan speed (rpm) 6000
Certain units have built-in fans to keep the unit cool. The fan speed is monitored and if it deviates from normal parameters too much, this will be taken as an indication of insufficient airflow over critical components and shutdown action will be taken.
9 SERIAL PORT
9.1 Connection
Your unit is fitted with a standard 'D9' plug or socket allowing it to be controlled from a computer or other type of terminal or console with a similar interface. Most computers fitted with an RS232 port, known as a 'COM' port, will have a 'D9' plug on them. To enable connection between the two devices you will require one of two cables as shown below:
| D9 connector type on C2 unit | RS232 cable type required for linking to PC |
| Plug – common on earlier C2 units ‘Null-modem’ D9 socket to socket | |
| Socket – common on recent C2 units D9 plug to socket | |
Should your PC not have an RS232/COM port, it is possible to add an interface card into the PC to add this facility. Another option you could use is a USB to RS232 converter. Both methods will add a COM port to your PC, although you should be aware that these generally do not default to being 'COM1' which is the default most RS232 applications will use.
Some units are also RS-422/485 capable – see the Specifications section for more details.
The default baud rate is 57600 with 8 data bits, 1 stop bit and no parity. This baud rate can be changed in the System menu to suit other programs if need be.
9.2 Communications protocol
The standard communications protocol for your unit is text-based and is detailed on our website. Also on our website, you can find the Windows Control Panel or CORIO®tool Suite for your unit.
The protocol is also bi-directional (unit and computer both send messages to each other), so that you can send changes to the unit, and it will also respond with any changes made via alternate methods (front panel buttons, menu changes and infrared control). This enables any attached computer to be aware of any changes made to the unit from an alternative source rather than itself.
What this means is that you can easily find out the exact command to send to the unit to tell it to perform a certain function. This can be seen by the data that is sent back to the computer when changing values on the unit. For instance, just by turning FREEZE on, by pressing the FREEZE button, will cause RS232 data to be sent to the computer that represents the command required to set FREEZE on. A second press, to turn FREEZE off, then sends the computer the command required to turn the FREEZE off.
Note: Any command you send to the unit will be replied to either with an error code or with the actual changed value. This may be different to the one you sent; for example, if trying to set a value too high or too low.
10 SERIAL / IP CONTROL SPECIFICATION
PLEASE NOTE: Not all units support Serial and/or IP (Ethernet) communications – check to see if this feature is present on your unit.
This section outlines how to control a unit via a Serial or Ethernet link (if fitted to your unit), using ASCII-based commands. It details how to send and receive serial data to perform many of the functions that a user has access to on the unit.
Not all units will support the full range of adjustments listed – this will depend on the complexity of the unit you have.
10.1 Communication protocol basics
Packets of ASCII data containing hexadecimal numbers are exchanged between the unit and controller via a Serial or IP link (you cannot use both at the same time).
The Serial standard is 57600 baud, 8 bits, no parity and 1 stop bit, although this can be changed by the user (see 'System' menu).
No flow control is used - however all control packets start with an ASCII 'F', end with carriage-return (13 decimal, 0x0D hexadecimal) and all such packets sent to the unit will be acknowledged (thereby provided software handshaking). Note that a line-feed (LF) should not be sent.
It may take around 30ms (0.03 seconds) for an RS232 command to be actioned and acknowledged – this will vary between different models.
ASCII-hex data is used where a number is encoded into its hexadecimal equivalent with leading zeros – e.g. Where '00' is decimal value 0, '80' is decimal 128 and 'FF' is decimal 255. In other words, two characters are sent for each byte encoded.
Any gap of more than 1 second between the characters of a control command sent will cause a time-out - and previous characters sent will be lost.
Write packets (sending command functions to the unit) are always 20 characters long (including a carriage return at the end). The unit will respond with a full 20 character message indicating what has changed. This returned payload will reflect the actual value of the parameter changed. If the user requests a value out of bounds then the limit value is used, and the payload will then reflect the limited value used.
Read packets (sent to request information from the unit) are always 14 characters long (including a carriage return at the end), the response from the unit will be a 20 byte message with the Write flag (since it is 'writing' the value back to the host) and the ACK flag set.
The ACK flag will be returned as 0 if the command is invalid for some reason – for example a bad FUNCTION, WINDOW, OUTPUT or PAYLOAD value. An ACK=0 message will be otherwise identical to the one you sent, so you know exactly which message has the error.
Any changes made to the unit using the front panel controls will also cause the full 20 byte message to be sent indicating the change that has occurred, thus enabling a program to stay 'in-sync' with the unit. In some cases (such as the execution of a macro) multiple 20 bytes messages will be sent indicating all the parameters that have been changed.
Only one message should be sent to the unit, another message can't be sent until a specific response is received from the unit (the user should look for a message with the same WINDOW, OUTPUT and FUNCTION values as they sent). If no message is received back within 1 second, there is likely to be a hardware communication problem (or wrong baud rate, etc.).
If absolutely required, to simplify programming the user may send packets one after the other with around 100ms (100 milliseconds) between each one. However, this will not work for all packets (such as Zooming into Still Images / Testcards or changing Logos) since this will cause the unit's micro-controller to be busy, so the user must experiment and satisfy themselves that this is possible.
10.2 Packet format
Below is a representation of data bytes in a single packet for a 'Write' to the unit to set a value:
| SOP | CMD | CHA | WINDOW | OUTPUT/ FUNCTION | FUNCTION | PAYLOAD x 3 | CS | EOP |
Below is a representation of data bytes in a single packet for a 'Read' to the unit to get a value:
| SOP | CMD | CHA | WINDOW | OUTPUT/ FUNCTION | FUNCTION | CS | EOP |
The table below details the function of each part of the packet:
| Packet part | Function |
| SOP(Start of packet) | This is always the ASCII letter 'F' to indicate the packet start. |
| CMD(Command) | ASCII-hex byte to indicate the type of command being sent.Each bit in the byte has a different function. Currently only the following bits are defined:Bit 7 = Write (0) or Read (1) request. Messages from the unit are always Writes.Bit 6 = ACK bit. Should be set to 0 for messages to the unit. ACK=1 |

| CHA(Channel)SOURCEorMACRONUMBER | This byte has multiple uses, and defaults to 0 unless used for:CHAWhen a channel number is used in the Adjust Sources section (see later).SOURCEByte to indicate the source channel to be altered (if appropriate).0x10 = RGB1, 0x11 = RGB2, 0x12 = RGB3, etc.0x30 = CV1, 0x31 = CV2, 0x32 = CV3, etc.0x40 = YC1, 0x41 = YC2, 0x42 = YC3, etc.0x50 = SDI1, 0x51 = SDI2, etc.0xD0 = OUT1, 0xD1 = OUT2, etc.0xF0 = TC1, 0xF1 = TC2, etc.MACROOr – for Macro related commands:Bit 7..4 = 0 ReservedBit 3..0 = Macro number |
| WINDOW/LOGO/BORDER | Bit 7 = 0 (Reserved).Bit 6..0 = Represents the window to be adjusted (for multi-channel units only).E.g. Window ‘A’ (the default for single-channel units) is sent as ‘41’ since 0x41 is ASCII for ‘A’. 0x61 is ASCII for ‘a’ (a Logo) and is sent as ‘61’. |
| OUTPUT&FUNCTIONHIGH | Bit 7..4 = Number representing the output to adjust 0 = Output 1, 1 = Output 2 (for multi-channel units).Bit 3..2 = Reserved (set to 0).Bit 1..0 = Bits 9 & 8 of the function code. (Remainder of bits [7..0] are in FUNC LOW.)E.g. If the function code is 0x234, and we want to adjust Output 2, then this byte is 0x12 |
| FUNCTIONLOW | ASCII-hex byte to indicate the lowest 8 bits of the actual function to set or receive (e.g. change Zoom value).A later table details all the functions available. |
| PAYLOADx 3 bytes | A series of ASCII-hex bytes carrying the data to send.Read requests have no payload - the payload is in the data sent back.Write packets require a payload, and this is always in 'triple-bytes' - i.e. 3 bytes are required, MSB first.e.g. ‘000001’ is 1 in decimal, ‘010000’ is 65536 in decimal, and ‘FFFFFFF0’ is -16 in decimal. |
| CS ASCII-hex byte that is the (check) sum of all previous bytes (excluding the SOP 'F' character).E.g. The command F0400410082000001C8 has the checksum of 04+00+41+00+82+00+00+01=C8, so the complete command to send is F0400410082000001C8.A short-cut for debugging allows the checksum to be replaced by 2 question marks, so in the previous example you could send F0400410082000001?? Instead. This is purely for test and debugging - you should normally use a checksum to ensure data validity. |
| EOP This is a carriage return (no line-feed) - ASCII code 13 (decimal). |
10.3 Function list
These are grouped together into their associated on-screen menus.
Your unit and this manual should be used to determine the actual function of each of the following, as only the menu text is listed here. Where an equivalent menu item does not exist on your unit, then that feature is not supported on.
Function codes are given in hexadecimal and adjustment range is in decimal (but always sent as hexadecimal!).
For dual-channel units the mode of operation also restricts what Window and Output can be used the following table shows the allowed combinations:
| Mode Allowed | Window and Output combinations |
| Switcher Output 1 (0x00) and Window A (0x41) / Z (0x5A) / Logo a (0x61) | |
| Independent Output 1 (0x00) and Window A (0x41) / Z (0x5A) / Logo a (0x61)OROutput 2 (0x01) and Window B (0x42) / Z (0x5A) / Logo b (0x62) | |
| Dual PIP Any | combination of Output and Window |
The following table is a list of all menu functions, their related function number and valid range of adjustment.
Please note that not all items will be available on all units.

10.5 Reading and writing macros
Depending on the unit connected there can be up to 7 macros stored in the unit. These macros can be programmed to perform a specific task, for example enable PIP mode, Position pip window at H=0, V=0, Zoom in to 120%.
The WIN and OUT bytes are not used for macro reading or writing and should be set to WIN=1A and OUT = 0
The CHA byte indicates the macro we are programming / reading / running. Macro 1 to 5 are CHA 0..4, CHA=5 is restore, CHA 6..7 are Macros 6..7.
Macro Restore (CHA=5) is read only, the units restore state is set by sending the Store command (0C8).
| Menu text | CHA | FUNC (Hex) | Range of adjustment (decimal) |
| Macro | |||
| Run macro | 0..7 | F1 | 0..1 = Run, Erase macro |
| Number of items within macro | 0..7 | F4 | Read Only |
| Function to adjust | 0..7 | F2 | 0..4095 |
| Value | 0..7 | F3 | Value for Function |
10.5.1 Reading a previously stored Macro
In order to read a macro the following commands must be sent in this specific order – no other commands should be sent between these messages. The CHA in these cases relate not to the source but to the macro we are reading.

The above example shows the read for all the items within macro 0. The first command reads the number of items available in the macro and resets the read address. Then the following items read the function and then the data for each of the items in the preset/macro. Following a read of the data for a macro internally the next item in the macro is selected for reading so it is not possible to read the same item twice without first re-reading the number of items in the macro.

This section provides step by step instructions for some common operations.
10.6 Operation of the Keyer
Some units come equipped with a very powerful Luminance and Chrominance Keyer. The Keyer can take some time to master and below is a breakdown and series of simple steps to help you master the Keyer's operation
When adjusting the values, please bear in the mind the following:
The Y value is the Luminance value, so 0 is black and 255 is very bright (white).
The U value is the B-Y component. This is the difference between the Blue and the Luminance value. If part of an image is black, grey or white, then its value is 128 (being the mid-point).
The V value is the R-Y component. This is the difference between the Red and the Luminance value. If part of an image is black, grey or white, then its value is 128 (being the mid-point).
10.6.1 Preparation:
- Enter the Adjust windows menu.
- Select the Source (this will be the foreground).
- Exit the Adjust windows menu.
- Enter the Adjust keyers menu.
- Ensure the Keyer is Off.
- Set all Y, U and V min/max values to [0] [255].
- Set all Y, U and V softness values to 0.
- Set all Y, U and V invert values to Off.
- Turn the Keyer On.
At this point your source image will have disappeared, since all colors have been keyed out.
10.6.2 Adjustment:
Knowing which color(s) you want to key out from the image, e.g. black to disappear, perform the following set of steps:
- Increase the Y Key Min from 0 until just before the required color (Key Color) appears.
- Decrease the Y Key Max from 255 until just before the required color (Key Color) appears.
- Repeat steps 1 & 2 for the U and V min/max values as well.
Adjust any of the Softness values to improve the key. If your input signal is slightly noisy or if you want to soften the edges within the image, then this may require you
to decrease the 'min' values and increase the 'max' values to broaden the range of colors keyed out.
At this point, only the key color should remain transparent.
11 EDGE-BLENDING SETUP
11.1 Introduction
Edge-blending is a method whereby two or more video/data projectors are used together with part of their images overlapping, thereby creating a wider (or taller) display more suitable for showing wide-screen video images. The term edge-blending relates to the fact that the overlap needs to be carefully handled to prevent the overlap causing image brightness problems.
This guide is intended to summarise how to setup such projectors when used with a suitable number of TV One's CORIO®2 scaling engines. The C2-7000 series are dual processors and therefore require only a single unit to perform both tasks, whereas other units will generally require two units to be used together, with a distribution amplifier on the input so that both units receive an identical video source.
![graph TD A["Image 1 Image 2"] --> B C["Blank"] --> D](/content/2026/05/999607/images/f5044633c6f954f17aa0ff6bad0932ac5bccb8f4c3e2dde89d3234cedb38d802.jpg)
Basic method of overlapping two projection images to create a larger one.
Because the two overlapping areas will create a brighter than normal image, 'blending' is performed on the edges to allow seamless merging of the images together. The 'blend' is basically an S-shaped curve that is applied to gradually reduce the brightness of the image at the edge, so that they can overlap properly:
S-curves for left and right projectors, with edges blended.
S-curves, when properly overlapping, will add together to result in full brightness.
11.2 Edge-blending requirements
To obtain the best edge-blending results, you will need:
- A perfectly flat projection screen. This is vital, or it will not be possible to perfectly align your two projected images with each other.
- Two matched projectors. Every projector on the market is different, with different lenses, projection methods, brightness, contrast, etc. Ideally you will need to identical projectors to obtain the best results.
- A solid table or mounting bracket. Once you've set up your projectors and aligned them, you will not want them to move – so some method of holding them in place with brackets secured to walls or ceilings, or simply a sturdy table, will be vital.
- Adjustable mountings (or more preferably projectors with built-in advanced adjustments). Proper alignment of two projectors can be very difficult, but will be aided by using some sort of mounting bracket that is easily adjustable. You may need to be able to move the projectors independently in all directions: left, right, up, down, forward, backward and also be able to tilt them to correct for any rotational errors.
- Adjustable projectors. Most projectors will offer certain advanced features such as key-stone correction. This will be vital to ensure proper alignment, as it will partly compensate for mounting problems.
- Of course, you'll need one or more CORIO®2 units (depending on the model) with the latest firmware that supports edge-blending.
11.3 Basic setup of the two projectors
![graph TD A["Rectangular Unit 1"] --> B["Server Unit 1"] A --> C["Server Unit 2"] A --> D["Server Unit 3"] B --> E["Connected Point"] C --> E D --> E](/content/2026/05/999607/images/e34baaccd2133d9ab1ac2fa3ae046b72f8495d24c43f93cb5c0ebf16e0ac0056.jpg)
Basic video projector setup showing overlap.
The above diagram shows how the two projects should be placed to create a wider than normal image. The amount by which they overlap is very important, as this will also relate to the zooming values to be used for each of the CORIO®2 scaling engines.
Zooming is required because each projector is showing slightly more than half of the projected image, and thus each channel needs to be zoomed into a different area of the original source picture.
At this point, it is only necessary to place the projector roughly where you would like them to be, with around 15% overlap horizontally. If your projectors are already fixed into position, check that there is around 10% to 20% overlap, or edge-blending will not be possible.
You must also ensure that both projects are in focus with the same zoom settings (if your projector has this). It is often worth doing a 'factory reset' on them to ensure that no other settings (such as gamma correction or tilt) are active.
11.4 Connections to the scaler(s) and projectors
For CORIO®2 units with two scaling engines (such as the C2-7000 series), use outputs 1 and 2 to connect to the left and right projectors respectively.
If two single-channel scalers (such as the C2-1000 or C2-2000 series) are used, then connector unit '1' to the left-most projector, and unit '2' to your right-most projector. Hereafter, we'll talk about Output 1 and Output 2 as referring to unit 1's output and unit 2's output.
For use with dual-channel scalers such as the C2-7000 series, connect your video source (e.g. a DVD player or computer) to an input on the C2-7000 unit. It is not necessary to feed two signals – the C2-7000 unit can use the same signal for both outputs.
For 2 single-channel scalers, you can either use a distribution amplifier so that a single video source is split into 2 signals, or use the 'loop' output available on some units.
11.5 Initial setup
This section describes how to start setting your scaler up. It is vital that your scaler is 'clean' of any user settings, so it is advisable to perform a full factory reset by either re-updating the firmware, or doing a factory reset (see earlier in manual for how to do this).
![graph TD A["tvone"] --> B["tvone"] B --> C["tvone"]](/content/2026/05/999607/images/84ed8195a18a74ab34dcb9820ffa2e632da0eca3905591ccdc18ff804aafe1b2.jpg)
Showing setup of zoom for each channel.
Figures 'a', 'b' and 'c' show how an original wide-screen image is 'split' into two using identical zoom values on Output 1 and Output 2. Zoom values for around 10% to
20% overlap are usually around 180%. In other words, not quite 2x zooming (since that would give no overlap at all).
Figure ‘a’ shows the original image and ‘b’ shows the two zoomed images. Note that the two images are at different ‘Pan’ positions – i.e. they are zoomed into different areas of the image – the left and right-hand sides. Figure ‘c’ then shows the images re-combined as they should eventually appear on your projection screen.
To produce the above effect, you'll now need to change some settings on the units:
- On a dual-channel unit, set the unit into 'Independent' mode – this runs both scaling engines independently as 1A and 2B.
- Go into the 'Adjust outputs' menu and ensure that both scaling engines are outputting the same resolutions. (Hint: use Toggle 1 / 2 (Shift-1) to switch between 1A and 2B on the C2-7000 series.)
- Go into the ‘Adjust windows’ menu and ensure that both scalers are set to the same ‘Source’, which needs to be your original video signal (e.g. from a DVD player).
- For Output 1 (1A), change the 'Zoom' value to 190%, with H pan% of 0% (fully left).
- For Output 2 (2B), change the 'Zoom' value to 190%, with H pan% of 100% (fully right).
If your projectors are properly setup and connected, with the scaler active with the above settings, you should now have a very rough overlap of the two images on a single projection screen. Where they do overlap you will see an over-bright part of the image, and most probably some overlapping errors.
11.6 Edge-blending activation
Edge blending is activated in the 'Adjust keyers' part of the menu, as follows:
-
Go into the 'Adjust keyers' menu.
-
For Output 1 (1A), change 'Edge blend' from 'None' to 'R' – so that it's right-hand edge is blended.
-
For Output 2 (2B), change 'Edge blend' from 'None' to 'L' – so that it's left-hand edge is blended.
You will also notice that some red and green lines have appeared. The red lines indicate the edge of the screen, and the green lines indicate the start or end of the blend. If these lines are not present, change 'E blend guides' to 'Auto' or 'On'. 'Auto' makes them appear only whilst you are in the 'Adjust keyers' menu. 'On' forces them to be on all the time.
11.7 Edge-blending overlap / size
The blend size needs to be the same on both keyers, and is related to both the output resolution ('Output res' in 'Adjust outputs') and the zoom value ('Zoom' in 'Adjust windows').
There is a formula for calculating the edge blend size (E) from the zoom value (Z) and horizontal pixel width of the output (H):
E = 2 ^ H ^ (1 - Z / 2 0 0) [pixels]
For example, with zoom (Z) at 190%, output resolution of 1024x768 (H=1024), we can calculate E as:
E = 2 ^ 1 0 2 4 ^ (1 - 1 9 0 / 2 0 0) = 1 0 2. 4 [pixels]
There is also a formula for calculating the zoom value (Z) from the edge blend size (E) and horizontal pixel width of the output (H):
Z = (1 - E / (2 ^ H)) ^ 2 0 0
For example, with E at 150 pixels, an output resolution of 1920 × 1080i ( H = 1920 ), we can calculate Z as:
Z = (1 - 150 / (2 * 1920)) * 200 = 192 [%]
For the recommended zoom value of 190%, the following edge blend horizontal sizes should be used for various output resolutions:
| Zoom % Output resolution | Edge blend H size |
| 190 640 x 480 64 | |
| 190 800 x 600 80 | |
| 190 1024 x 768 102 | |
| 190 1280 x 720 128 | |
| 190 1280 x 1024 128 | |
| 190 1600 x 1200 160 | |
| 190 1920 x 1080i 192 |
To set these edge-blend widths, perform the following:
- Go into the 'Adjust keyers' menu.
- For Output 1 (1A), change 'E.blnd size' (the first number) to the H size recommended above.
- For Output 2 (2B), change 'E.blnd size' (the first number) to the H size recommended above.
It is very important for Outputs 1 and 2 to use the same blend width, or you will not be able to accurately blend your images. However, should your projectors be mismatched, changing the blend width on one or both of them can sometimes help – but this should be done as a last resort.
11.8 Edge-blending guide lines
These lines, as mentioned earlier, are used to aid the alignment of your projectors. They show the area to overlap – the red lines indicate the inside edge of the output resolution, whilst the green lines indicate the edge of blending. (G marks the green lines, R marks the red, Y marks the yellow, for those reading in black and white.)
Outputs 1 and 2 with guide lines shown.
Outputs 1A and 2B partly overlapping.
Outputs 1A and 2B perfectly overlapping – the red and green lines turn to yellow when aligned
11.9 Alignment of projectors
This is possibly the most difficult part of properly setting up edge blending. Using the guide lines, you need to fine-tune your projector positions and tilts so that the above-mentioned red and green vertical lines perfectly overlap to produce yellow ones.
Depending on how your projectors are aligned, you'll get different results, each with different solutions as detailed below:
Too far apart – you need around 15% overlap, such that the red and green lines overlap.
![graph TD A["Input 1"] --> B["Process Unit"] C["Input 2"] --> B B --> D["Output 1"] B --> E["Output 2"]](/content/2026/05/999607/images/8d917bdb631e31f4357c97d04408235a814fae2ba612a84b6767c0d6c084be90.jpg)
Offset – make sure your projectors are perfectly aligned both horizontally and vertically.
![graph TD A["Block 1"] --> B["Block 2"] B --> C["Block 3"] C --> A A --> D["Block 4"] B --> E["Block 5"] C --> F["Block 6"] D --> G["Block 7"] E --> H["Block 8"] F --> I["Block 9"]](/content/2026/05/999607/images/8fecdc97a9d315ee6808e52604c8d300b6aee57ae0379b0ab2be5b774d039065.jpg)
Key-stoning – ensure your projectors have the same keystone values, to produce perfectly aligned vertical lines.
![graph TD A["Box 1"] --> B["Box 2"] B --> C["Box 3"] C --> A A --> D["Box 4"] B --> E["Box 5"] C --> F["Box 6"] D --> G["Box 7"] E --> H["Box 8"] F --> I["Box 9"] G --> J["Box 10"] H --> K["Box 11"] I --> L["Box 12"]](/content/2026/05/999607/images/8bcf9140ad5b2c026878cf18966a9ca941b81abae46434429e2537b070de7275.jpg)
Rotation – one or both of the projectors has a slight tilt. Once corrected, you may then need to re-align them.
Perfect alignment – your red and green vertical lines should overlap to produce yellow ones.
11.10 Gamma correction
By now you should have two perfectly aligned projectors, but possibly with a brighter than normal overlap. This is most probably because a projector's luminance is not perfectly linear and therefore will need to have what's called 'gamma correction' applied.
Gamma correction is available within the same ‘Adjust keyers’ menu as the other adjustments. You will need to adjust both output channels gamma correction to be the same, unless you have non-matching projectors.
To change gamma correction:
- Go into the 'Adjust keyers' menu.
- For Output 1 (1A), change 'E.blnd gamma' (the first number) until the brighter area starts to dim – note the number required for this.
- For Output 2 (2B), change 'E.blnd gamma' (the first number) to the same gamma value as per above.
- Repeat steps 2 and 3, changing up or down as necessary until the bright patch has disappeared.
The 2nd number in the 'E.blnd gamma' is for where you have projectors stacked vertically - e.g. for a 2x2 edge blend arrangement. The 1st number adjust the horizontal blend's gamma value, whereas the 2nd controls the vertical blend's gamma value.
Note that it may not be possible to completely remove a bright patch – this is because some projectors can not actually output completely black images, with some light always leaking through. However, the next adjustment is designed specifically for this.
11.11 Brightness compensation
If you find it impossible to completely remove the centre overlap for all images (i.e. dark images and bright images being projected), then two extra compensation adjustments are provided to help with this.
The compensation is needed because most projectors cannot output pure black – there's always some light 'leaking' to the projection screen. Thus when you're trying to output black, there will be a 'hot area' where the two projectors are now overlapping, of twice the projector's 'black level' output.
The solution is to adjust the ‘Eb comp cent’ value (the first in the ‘Eb comp cent/side’ menu) to compensate for this centre brightness error. By increasing this value, it will increase the brightness of the non-overlap area.
To get this value right, you must first make sure that the units connected to the projectors are outputting black – e.g. in the Adjust windows menu you can disable the output. Then increase the 'Eb comp cent' value until the non-overlap area's brightness has increased to be the same as the overlap (centre) area.
The 2nd value ('Eg comp side') is for where horizontal and vertical edge blending is being performed – e.g. a 2x2 arrangement. This value increases the brightness of the overlapping areas, with the exception of the centre 'square' where all projectors overlap.
11.12 Aspect ratio adjustment
Since your original video source is probably 16:9 (or a similar aspect ratio), it will also be necessary to change your vertical zoom value differently to the horizontal one. This is best done after projector alignment by performing the following:
- Go to the ‘Adjust windows’ menu and change ‘Aspect adjust’ to ‘Advanced’. This enables separate H & V zoom adjustments.
- Go to 'Adjust windows' for Output 1 (1A) and you will now be able to adjust the vertical zoom independently of the horizontal zoom. H zoom should be left as it is, so adjust the V zoom until the correct aspect ratio of your output is achieved.
- Go to 'Adjust windows' for Output 2 (2B) and adjust the V zoom to the same value as Output 1 (1A).
11.13 Locking both outputs together
If your video source contains live (moving) video then it is worthwhile locking one channels' output to the other's – this will eliminate any line or frame drift, which may cause frame-rate conversion problems. This is best done by locking Output 2 to Output 1.
For dual-channel units such as the C2-7000 series, perform the following:
- Go to 'Adjust outputs'
- Ensure that '2B' is selected – press Toggle 1 / 2 (Shift-1) if not.
- Where 'Lock [Off] RGB1' is seen (where RGB1 is the default Lock source), change the Lock source to 'OUT1'.
- Then change the Lock method from 'Off' to 'Genlock'.
For single-channel units (such as the C2-1000 and C2-2000 series) you can probably only perform locking if RGB1 is available for use (i.e. you are using CV1 or YC1 as your video source). If so, perform the following:
- Either use a 2nd output from the unit with Output 1, or a distribution amplifier to generate a 2nd identical signal. Feed this into RGB1 on the unit handling Output 2.
- Go to 'Adjust outputs' for Output 2
- Where 'Lock [Off] RGB1' is seen (where RGB1 is the default Lock source), change the Lock source to 'OUT1'.
- Then change the Lock method from 'Off' to 'Genlock'.
11.14 Other setup approaches
The previous setup method relies on your projectors being moved and aligned to the 190% zoom factor. Other setup approaches are also used where the zoom factor is adjusted to the projectors' current position – for instance if they are already fixed into their final positions.
Assuming your projectors are in fixed positions and you can't move them, you will need to adjust the 'E.blnd' H-size for both Outputs 1 and 2 to be the same values such that they overlap, creating the yellow lines mentioned earlier. You will then need to adjust the zoom values according to the formula given earlier. For various zoom and output resolutions, the following values for the edge blending H-size can be used:
Table showing Zoom% values for various Horizontal resolutions and edge blend H size overlaps.
A powerful utility is available for the C2 product range and can be downloaded from our support web site or found on the Product CD (where supplied). To install the application click on the setup file and follow the on screen instructions.
Once installed you will be able to control your unit via either Ethernet or Serial (RS232) and be able to change and store all the settings of the unit.
12.1 Opening screens
When you start the application you will be presented with a splash screen showing the product version number and then the main screen. The toolbar menu for communications allows you to change the communications method that the application will use.
12.1.1 Selecting a serial port connection
Select the Communications item from the Communications toolbar. Then click the "Serial" option on the popup window.
Figure 1 Communications – Serial
The application will support up-to 10 serial ports, all other parameters normally associated with serial communications such as the baud rate are already configured. The application works with a baud rate of 57600 baud only, you should ensure that the baud rate is correctly set in the unit (System menu on the unit – see 8.9) before trying to connect.
12.1.2 Selecting an Ethernet connection
For units where an Ethernet port is provided, select the Communications item from the Toolbar Communications. Then select the "Ethernet" option on the popup window, the following options will be shown.
Figure 2 Communications - Ethernet
In the Ethernet section be sure to set the IP address to the same as the address you have set on the unit (units Ethernet menu). The port number used should also reflect the port number on the unit.
If there are multiple units on the network then this port number should be the same for all units, only the IP address must be unique.
12.2 Connecting to a unit
This main screen allows you to operate the application in one of two modes, firstly "Demo" mode which allows you to familiarize yourself with the unit control without having a unit connected. To use demo mode select the product to demo from the dropdown box and then press Demo mode.
Figure 3 Main screen
Secondly "Connect" mode which connects to a device that you have attached via Ethernet or Serial. On pressing the Connect button, the software will detect the unit connected and show the appropriate controls and features.
Figure 4 Detecting a unit
Once the application detects and connects to a unit you will be asked if you wish to "synchronize with the unit", this will read all the settings from the connected unit and update the application.
Figure 5 Synchronize application
Once synchronized any changes made on the unit or on the application will be reflected on the unit and the application.
12.3 Application menu's
12.3.1 File menu
Figure 6 File menu
Across the top of the application are the toolbar menu options. The first menu item is File within this menu you can Save and Load previous setups into the application, these setups contain all the settings of the unit. Following a Load the application will ask if you would like to synchronize the unit, if you do not synchronize then the unit and the application will show different values.
12.3.2 Communications menu
Figure 7 Communications menu
The communications menu provides the Connect item which provides a means to disconnect from the unit and return to the main screen. Read from unit is very important as it allows selective or all of the settings to be read from the unit. Depending on your unit some of the following Read from unit menu items are not available.
- The Read All option will read each of the setting sections from the unit and update the application. This item should be selected following connecting to a unit as it will synchronize the unit and the application.
- The Read Macros will read the macros that are stored within the unit.
- The Read Buttons will read the button assignments from the unit and update the buttons and the buttons tab within the application.
- The Read Resolutions will read the complete resolution database that is currently stored in the unit. This step must be performed in order to select resolutions by name and to be able to edit resolutions.
- The Read Parameters will read the all of the adjustments from the unit and update the applications.
The last menu available in Communications is Program into unit this allows selective or all the settings to be programmed into the unit.
- The Program All menu will program each of the settings sections into the scaler.
- The Program Macros menu will program only previously read or loaded macros into the unit.
- The Program Buttons menu will program the button assignments into the unit
- The Program Resolutions menu will program the resolutions into the unit as defined on the resolutions Tab.
- The Program Settings menu will program all adjustments into the unit
12.3.3 Tools menu
Figure 8 Tools menu
The tools menu provides access to the scripting tool, image loader and show settings. The Scripting tool provides the ability to create complex scripts, which can be used to instruct the unit to perform multiple operations with just a single button click.
The Image Loader provides the ability to program Logos and Still Images / Testcards into the unit. The source image can be in JPG, BMP or GIF format which is then compressed and downloaded to the unit. For Logos the Image Loader provides the ability to set two key colours that will appear transparent when downloaded into the unit.
Finally the Show Settings item will show all the settings that are currently active within the application.
12.3.4 Resolution menu
Figure 9 Resolution menu
The resolution menu provides the ability to Load previously saved or downloaded resolutions into the resolution editor. Once a resolution table has been modified then it can be saved to a resolution text file.
12.4 Scripting tool
The scripting tool is a very powerful feature of some units as it allows complex sequences of adjustments to be performed using a single button press.
Figure 10 Scripting button screen
Up to 24 buttons/functions can be defined, and each of these buttons/functions can perform multiple actions.
Figure 11 Script editor
In order to edit or create a script select Script->Edit from the menu, this will then present the script editor as shown above.
The script editor is based around a simple drag and drop interface, in order to create a button action you drag the required operations to the correct 'Define Button' section. As can be seen in the example above for Button2 we have multiple actions which are cycling sources and then waiting for 2000 milliseconds before selecting the next source.
12.5 Image Loader
On some units it is possible to store Logos and/or Still Images / Testcards. Still Images / Testcards are full screen images that operate much as another input source so they can be shrunk, zoomed, faded, keyed, blended and positioned anywhere on the screen. The Logos are pre keyed and of a fixed size on the unit. The Image loader provides the ability to key out a range of two separate colours, and set the logo size.
12.5.1 Loading Still Images / Testcards
Figure 12 Image loader
To program a Still Image / Testcard into the unit select the 'Testcards' tab from the image programmer screen and then press Load Image.
You can select JPEG, BMP and GIF images. The image will be loaded and shown on the screen. You should then enter a name for the image – this name, limited to 24 characters, will be shown on the unit when it is selected as a source.
The image number is the 'slot' that the image will be loaded into within the unit, there are between 10 and 15 'slots' available depending on the unit type.
Pressing program will convert the image into its raw RGB values and then compress it, if the image is too large once compressed then the programming sequence will stop and report that the image is too large / complex.
Selecting the ‘Reduce image size to fit memory’ option will cause the application to automatically shrink the image and then recompress until the image will fit into the units memory. This will reduce the quality and detail in the image, but make it fit into the unit. If the resizing of the image is unacceptable then the complexity of the image may need to be reduced. You should refer to 12.5.3 for a guide to producing an image that will be suitable for the memory space available in the unit.
12.5.2 Loading Logos
Figure 13 Logo Loader
To program a logo into the unit select the 'Logos' tab from the image programmer screen and then press Load Image.
You can select JPEG, BMP and GIF images. The image will be loaded and shown on the screen. You should then enter a name for the Logo – this name, limited to 24 characters, will be shown on the unit when it is selected.
The Logo number is the 'slot' that the Logo will be loaded into within the unit, there are between 10 and 15 'slots' available depending on the unit type.
If you do not need to key out any part of the logo then simply press 'Program' Pressing program will convert the image into its raw RGB values and then compress it, if the image is too large once compressed then the programming sequence will stop and report that the image is too large / complex.
To key part of the image select the 'Keyer' checkbox. You can now use the mouse right and left click to select up to two colours to key from the image. Pressing 'preview key' effects will refresh the image showing the keyed areas as transparent. The 'Invert preview background' checkbox will for preview purposes add a background to keyed image to allow for easier key adjustments.
Should the edges of the keyed portions of the image still show shades of the Key colour then the softness adjustment should be altered until the required key effect is reached. If the softness adjustment is not sufficient then selecting the 'Edge filter' option will detect edges of the key areas and apply further softness.
Once programmed if the logo is too large on the unit output then adjust the 'Logo shrink' and reprogram the logo.
12.5.3 Maximum Image size – how large can my Logo / Still Image / Testcard be?
The image size for a Logo or Still Image / Testcard is limited by the amount of memory available in the unit; this is approximately 128kbytes of compressed image for a Still Image / Testcard and approximately 32kbytes for a Logo. The compression used by the Image loader is Run Length Compression.
This provides excellent compression for simple images with well defined contiguous blocks of colour such as logos. However the effectiveness of the compression is reduced when images are anti-aliased, for example:
If we take a single line of pixels and look at them closely we will see for a non aliased image solid pixels of one colour. If we look at a line when anti-aliased we can see that no longer is the leg made of solid pixels but of varying shades this will cause an increase in complexity and reduction in compression.
So how large can the source logo / image be? The size of the original image is a minor factor; the most important factor is the complexity and amount of anti-aliasing that is present.
12.6 Resolution Editor
On some units it is possible to modify the resolutions that can be output and input; where this is available a Resolutions tab will be shown on the main screen. This tab will show the resolution database editor, and creation tool.
Figure 14 Resolution editor
There are 2 ways to create a resolution using this tool. The easiest, shown on the New resolution tab at the side, allows you to create a new resolution using the minimum information of Horizontal and Vertical size and the desired refresh rate. It's also possible to constrain the Vertical size of the resolution by selecting a custom, 4:3 or 16/9 aspect ratio and then left clicking your mouse on the Vertical Resolution box which will then automatically calculate the Vertical Resolution for the given Horizontal Resolution and Aspect Ratio.
Once you have entered the required information it's simply a matter of pressing the 'Create' button. The resolutions are created using one of two VESA® standards, Coordinated Video Timings (CVT) or Generalized Timing Formula (GTF) in order to make the created resolutions as compatible as possible with standard video equipment. If you find your created resolution does not work effectively try the calculation using GTF.
Once you press the Create, you're asked if you want to add this new entry to the resolution table. If you select No, the resolution can only be added to the table using the Advanced Create and edit screen.
Once the new resolution is created the 'Scaler menu values' frame will show what the unit's on-screen values would be if you were in the 'Adjust Image Parameters' screen.
Figure 15 Resolution editor - Unit on screen values
If the resolution was added to the resolution table, then the table at the bottom of the screen will update and show the newly created resolution and all its timing parameters. New resolutions are named using the resolution H and V size; refresh rate and the letter U to signify a user created resolution. Using the Timings tab you can alter this text.
Figure 16 Add resolution to table
Once your new resolution is added, you can program the resolution into the Scaler using the Communications menu and then selecting Program into unit and then selecting Program Resolutions. The application will proceed to program all the resolutions on the list into the scaler.
Note that this will overwrite any resolutions currently in the scaler.
The second method of creating a resolution requires you to know all the detailed timing parameters. The timings tab allows all the detailed video timing information to be added and altered, including the title of the resolution entry (limited to 24 characters).
There are also along side the detailed timing parameters several flags that are used to specify the signal type these are interlaced – for interlaced video signals, CCIR for video that would normally be output on CV or YC connectors and RGB for video that would be output on RGB or Component type connections.
Figure 17 Resolution editor - advanced timings
In order to modify an existing resolution simply click on the resolution table at the bottom of the screen and it parameters will be editable within the Timings tab. Once the edits are complete click on Update to modify the settings for the selected resolution or Create New to keep the selected resolution and create a new resolution with modified parameters.
13 TROUBLESHOOTING AND TECHNICAL SUPPORT
If problems are experienced, please read through the symptom topics below in order to resolve the problem. After doing so, if you still need to, contact Technical Support at http://www.tvone.com/support. Please have the following details of the problem handy:
Whether the problem happens only at specific times or has only just started occurring (and what other things have changed at the same time).
Firmware revision numbers - found in the first item of the System menu:
If the problem relates to a specific source or resolution:
13.1 There is no picture on the Output.
If no LEDs are on, then ensure that the AC power adaptor is connected properly and the power switch is on at the AC outlet.
If the Standby/ON LED on the unit is off but another blue LED is active then check that the monitor output from the computer is connected at both the computer and the unit. Check that the output connector you are using from the unit is also connected at the unit and the display equipment.
Check that the display video equipment is set to the correct line input and format/standard as appropriate.
Check that the device connected to the output is on and can support the resolution set in the Adjust output menu, ensuring that the Sync type e.g. RGBHV, is also set correctly.
13.2 The image is shifted and not fully viewable
There are several ways to correct this, depending on the actual problem, although it's generally best to perform a Factory reset.
Try an AUTOSET if the input is RGB or YUV/YCbCr. Next adjust the TL pos. adj. values in the Setup Program source menu until the incoming video signal is displayed correctly. You may also need to adjust the BR size adj. setting to ensure the incoming video signal is properly displayed.
13.3 The output resolutions no longer appear as expected.
Because any changes made in the Adjust resolutions menu are automatically stored, it may be that the resolution data has become altered or corrupted beyond the ability of a display to show it.
Either manually correct the resolution data, or restore the data to full factory conditions by doing a firmware update. The user should avoid altering the resolution parameter data unless absolutely necessary.
13.4 There is excessive flicker on the Output.
Try using a different Flicker reduction mode. Turning the contrast down and the brightness up on the output device can have a large effect on flicker. Or try adjusting the brightness and contrast of the source input by selecting the Input adjust menu.
13.5 The Output image is distorted.
This may occur where some of the areas of the image are very dark and others are very bright. The solution is to adjust the contrast and brightness settings on your Output device to rectify the problem.
Alternatively, if the Adjust resolutions menu has been used to the output resolution in question, a firmware update is recommended to perform a FULL factory reset.
13.6 Some colors appear to be incorrect on the CV/YC output
First try altering the color, contrast and brightness settings on your TV or video display. These are usually set up for a very different reason than viewing computer graphics and may need changing to suit. If you cannot achieve exactly what you desire then alter the inputs levels in Adjust sources until the correct colors are restored.
13.7 How can I reduce color smearing on CV connections?
Smearing usually occurs on Composite Video connections and is generally unavoidable - unless you can switch to using S-Video or RGB / YUV connections. It occurs because the brightness and color information is transmitted as one combined (composite) signal and the two parts have to be 'bandwidth-limited' to avoid them interfering with each other – which then reduces the quality.
13.8 I can no longer adjust the Output image resolution.
When the unit is in Lock mode, the output resolution is fixed to be the same as the Lock source input resolution. During this time the Output image menu item is not displayed.
13.9 The picture on the video display is black and white.
Ensure that all the cables are correctly connected. If you are using a PAL TV to display the output then the unit may be providing resolution set to NTSC mode, or vice versa.
13.10 The picture on the video display is green.
The Output type is probably incorrectly set to YUV mode, whereas you are connecting to an RGB monitor – see Adjust outputs menu.
13.11 The RGB input is selected but the image is rolling or pink.
Check the Adjust sources menu and confirm that the input type and sync method is set correctly. (Having YUV input selected, instead of RGBHV often causes this problem).
13.12 The video signal from my DVD player does not appear to work.
Some DVD players have a switch at the back that selects between 'Component' and 'S-Video' output, because most will not let you output both at the same time. Make sure it is in the right position for the output you want.
13.13 Image is flashing, snow is present, or source image does not appear.
You may be experiencing a HDCP compatibility problem.
If one of the sources you are using is HDCP encrypted, and your unit is not set to output HDCP, then your unit will not allow the source image to pass through the unit (it may flash on and off).
The solution (if your unit supports HDCP) is to ensure it is enabled in both 'Adjust outputs' and in the 'Adjust sources' menu for that source signal.
If you unit does not support HDCP, or your output device does not support HDCP (e.g. an analog monitor), then there is no way to display a HDCP encrypted source signal.
14 RETURN PROCEDURE
Before returning your unit for repair, there are several checks you can make yourself to make sure the problem is actually caused by a failure.
14.1 Are you sure there's a fault?
Many 'faults' are due to incorrect set-up or use so a simple checklist is provided below to help you identify potential problems.
Set the unit up with your equipment as described in this manual and run through the checklist. This will hopefully determine whether or not the unit is actually faulty and prevent units from being returned unnecessarily.
Check the Troubleshooting tips of this manual and check out the various FAQ (Frequently Asked Questions) listings on the support website,
http://www.tvone.com/support, which shows the latest Hints, Tips and Solutions.
Don't presume it is the unit that is causing the problem. Check that the equipment being used with it is fully working and setup correctly – bypass the unit if possible by connecting the video source directly to the video display.
Check the AC power. Is it present and is the unit turned on? Check that all cables are properly plugged in and are not damaged and then make certain that all equipment connected to the unit is working properly.
Perhaps you have a "frozen" unit and you cannot change an input nor exit from the current task. In that case, a simple 'Factory Reset' of the product may sort the problem out. See earlier section on Front panel buttons to do this. Note that all user-settings will be lost following an engineering reset.
It is also worth ensuring that the latest firmware is installed in the unit – although, again, user settings are lost during a firmware update.
14.2 To return a unit for repair
First contact TV One using the http://www.tvone.com/support website. Support personnel will determine whether a return to the factory is the appropriate solution. If that's the case, a Return Authorization Number will be issued. You should provide the following information for each unit:
Product type
Serial number of the faulty unit (this is on the underside of the unit)
Full details of fault
Invoice number (if available)
Units should be returned via insured carrier or registered mail (thus allowing a trace to be made if the Processor is lost in transit), with shipping costs and insurance arranged at your own risk and expense. Goods in transit are the responsibility of the sender and the supplier will not be responsible for transit losses.
Please clearly state the return number on the outside packaging and on any accompanying documentation. This will greatly speed up processing.
IMPORTANT: DO NOT return a unit for warranty repair without first obtaining a Return Authorization Number. No action will be taken on a unit returned in warranty for repair without a Return Authorization Number
