Broadcast-Quality Conversion

Io XT features hardware-based full 10-bit broadcast quality motion adaptive SD to HD up-conversion, HD to SD down-conversion and HD to HD cross-conversion.

The quality of the conversion features found in the Io XT is virtually identical to AJA's award winning stand-alone converter products used throughout the post production market. The Io XT built-in up converter uses a full 10-bit path, fully motion adaptive de-interlacing, and large multi-point digital interpolators. Down-conversion uses large multi-point digital interpolators, anti-alias filtering and interpolation.

Cross-conversion is high-quality hardware-based and offers true broadcast picture quality in realtime. Because these functions are in hardware, they are available full time, all the time—with no CPU load. Such conversions are useful for cost effective monitoring, making standard definition dubs of an HD project, or up-converting from a standard definition project to an HD deliverable.

Figure 2. Io XT Connectors

Figure 3. Io 4K Connectors

Connector Descriptions

The following section describes the connectors offered on the lo XT and lo 4K chassis in the following order:

• Connectors common to both models
• lo XT connectors
• lo 4K connectors

Connectors Common to Both Models

HDMI Input and Output:

Two HDMI connectors on the Io XT/4K provide input and output of HDMI video and multi-channel embedded audio.

• lo XT has HDMI v1.3a capability at 30 bits per pixel allows full support of the latest 10-bit monitors.
• lo 4K has HDMI 1.4 capability, supporting Ultra HD and 4K resolutions at up to 30 frames per second.
• Both Io XT and Io 4K support 2 or 8 channel HDMI audio input and output.

HDCP is not supported on either input or output. Io XT/4K HDMI output does not have HDCP, and input sources having HDCP are not supported. The HDMI input is designed to support long cable runs—up to 100 ft. when using 22 or 24AWG HDMI cable, or up to 50 ft. using 28 or 30AWG HDMI cable. The HDMI output supports standard HDMI cables only.

RS422 Machine Control:

A female DE-9 connector on Io XT/4K provides connection for VTRs, camcorders, disk media servers, and other devices using RS422 SMPTE (Sony) protocol. (Connector pinout is listed in Appendix A, see "Machine Control" on page 58.)

Reference Video and LTC Input:

Two BNC connectors on lo XT/4K provide reference Input and Output. The Reference Video input can also be used for LTC input. The selection of Reference (sync) or LTC is set using the AJA Control Panel ("Input Select Screen" on page 33).

In Video Pass-through mode, these connectors are effectively loop-through. Supplying reference signal to the Reference input allows you to synchronize lo XT/4K outputs to your house analog reference video signal (or black burst). If you have a sync generator or central piece of video equipment to use for synchronizing other video equipment in your studio, then connect its analog composite output here. When lo XT/4K outputs video, it uses this reference signal for locking. When connecting a reference video source, the locking signal should be the same format as the Primary format selected in the AJA Control Panel. It is possible in some circumstances to use an alternate format video signal as long as the basic frame rate is compatible.

Balanced Analog Audio Output:

A 25-pin DB connector provides 8-channel, 24-bit D/A analog audio, 48kHz sample rate, balanced via 8x XLR on DB-25 breakout cable. (Cable not supplied.)

12V Power Connector:

A standard 4-pin XLR type connector is provided for either battery or line source power using the supplied AC power adapter.

Io XT Connectors These connectors are used only on the Io XT model.

Thunderbolt ports:

Two Thunderbolt ports are provided as describe in the figure above. These are first generation Thunderbolt connections.

HD/SD SDI Input and Output:

BNC connectors are provided on Io XT for two HD/SD-SDI inputs and two HD/SD-SDI outputs. The input and output support video and embedded 24-bit digital audio. Use SDI wherever possible for the best quality 10-bit uncompressed video input, capture and

	output. If peripheral equipment has a variety of inputs/outputs, look to see if it has SDI I/O, and use it where possible. Most high-end professional broadcast equipment supports SDI (VTRs, cameras, media storage servers, etc.).
Component Video Output:	Io XT features a group of 3 BNC connectors for output of component, composite and Y/C functions. The signals are labeled on the BNC connectors on the rear panel of Io XT.
A Note About YPbPr:	Component Video, or YPbPr, has been given several names over time. YUV, Y/R-Y/B-Y, and YCbCr, are just some examples. Although these various formats have some differences in levels, they are all basically the same. Io XT uses the modern YPbPr terminology exclusively. Io XT supports three different types of YPbPr: SMPTE/EBU N10, Betacam (NTSC), and Betacam (NTSC Japan). These three formats differ in level only and are configured via the AJA Control Panel.

Io 4K Connectors These connectors are offered only on the Io 4K model.

Thunderbolt 2: The Io 4K provides the second-generation Thunderbolt ports to support UHD and 4K signals. Two ports are provided for "daisy-chained" network configurations.

Bi-directional SDI I/O: Four bidirectional BNC connectors can be configured via the AJA Control Panel for:

• HD/SD inputs (x2) and outputs (x2)

- Or you can input or output 4 channels of video representing individual quadrants of the higher definition Ultra HD (3840x2160) and 4K (4096x2160) formats.

NOTE: The lo 4K can only be configured for either input or output of 4K at a time. It cannot support 4K input and output at the same time since both require four BNCs.

Dedicated SDI HD/SD Output: One BNC connector is provided for full-time, real-time output of HD/SD video. 4K video is down-converted to 2K HD and UHD is down-converted to HD.

Installing lo XT/4K Software

	The AJA Control Panel is a software application that provides a simple visual window showing how the lo XT/4K interface is currently configured, and that allows you to make changes. Settings—both those you changed and those you didn’t—can be named and saved as a snapshot for recall at anytime. This lets you save settings associated with all your frequent tasks; then as you switch tasks you don’t have to spend extra time resetting interface configurations—just load the previously saved settings for each task. If you work on multiple systems and want to carry your saved setup to another location, you can copy your saved Presets file on to movable storage and load it into any AJA-equipped system (see “Presets Screen” on page 45 for more details).
Single-user & Network Settings	The AJA Control Panel offers preference settings that support both:User Preferences— Preferences stored from the last Control Panel State to be used on next startup of AJA Control Panel.Shared Preferences— Preferences saved by an Administrator for use as a default start state for AJA Control Panel.
User Preferences:	This file exists to immediately, automatically, store preference changes made by a user on a particular AJA device. When any control is changed in the Control Panel, that change is recorded in the preferences file stored in a unique user preferences location dedicated to that particular device and serial number. Then, when AJA control panel is restarted for any reason, it will restart with the same preferences it used when it closed.However, if a user sets their preferences, and then replaces the AJA device with a different one, the Control Panel will either:Start up with the factory defaults, orStart up with the “house defaults” dictated by the system administrator (if a Shared Preferences file exists).The User Preferences File can be found in the following locations.On Mac:/Users//Library/Preferences/com.aja.devicesettingsOn Windows 8:C:\Users\AppData\Local\Aja.com.aja.devicesettings
Shared Preferences:	An administrator can establish house standards for the AJA Control Panel by creating the user preferences file (described above) and placing it in a shared location where it will establish a standard default startup state for all users of a given computer system. These settings preempt the initial AJA default settings.To establish the House Default for every user on every system, a system or network administrator can move this default file to all systems on the network (manually or by pushing it out across the network). All users on the network will then open to the House Defaults when they launch the AJA control panel for the first time.
NOTE:	If the user makes changes to the control panel themselves, those changes will be saved in their user preferences, which will take priority over the house default dictated by the shared preferences file.The Shared Preferences file should be a file created at the User Preferences location described above, and placed by the System Administrator in the following locations.

On Mac:

• /Users/Shared/Library/Preferences/com.aja.devicesettings

On Windows 8:

• C:\Users\All Users\Aja\com.aja.devicesettings

Block Diagram Screen

The AJA Control Panel represents a visual block diagram of the unit's configuration. The current status, input and output settings, and many other details are depicted in the color-coded block diagram.

The top area of the Control Panel is a visual representation of the processing, if any, that's currently occurring, including inputs/outputs, reference source, and system status. Lines between inputs, the framebuffer, and outputs, show a video path. Where there are no lines, there is no connection; this can be because an input or output isn't selected in the Input Select menu. The lines will also show whether the outputs are video or video + key.

Icon objects in the block diagram screen (input/output icons, frame buffer, etc.—indicate their status by color (described later). You can click any of the screen selection links in the left column to view its current settings or click on an icon to call up its related settings screen (for example, click an HDMI icon to call up the HDMI screen information). You can also right-click or Control-click to see context-sensitive information and choices. Figure 20 & Figure 21 show the IoXT and Io 4K Control screens.

Figure 20. AJA Control Panel, Block Diagram for IoXT

Figure 21. Io 4K, Block Diagram set for UHD Format

Framebuffer:

The framebuffer is the "memory" in Io XT/4K where your third-party applications interface with the hardware. The framebuffer has a format (called the "Primary Format" and color space that it follows, as defined in the linked menu screens or via external application software. It is important to realize that the computer can contain many applications that can use the Io XT/4K (as you switch from window to window) and it may not always be obvious which currently controls it.

Figure 22. Control Panel In Use Message (in red)

    D["1080i29.97"] --> B
    E["In use by Control Room"] --> F["Disabled SDI 1"]
    G["Disabled SDI 2"] --> H["Disabled"]

In the top right corner, the Control Panel displays the name of the application controlling the unit. In some cases, applications may not always properly "let go" of the I/O interface as another takes over—you'll be able to tell by looking at the Control Panel.

Color Meanings:

All items in the AJA Control Panel block diagram are color-coded to show what is happening in realtime. This applies to both icons and text. These colors have the following corresponding meanings:

• Blue: video is same format as the Primary Format (framebuffer)
  • Red: the selected operation cannot be performed
• Yellow: reference video (black burst or other reference source)

- Green: indicates that Io XT/4K is performing an active change to the video making it different from the Primary Format (e.g., down-conversion).

Primary & Secondary Video Formats

In Io XT/4K operation, the Primary Format is the media format written to disk and used in your project. The Secondary Format is a selection for format conversion.

Primary Format:

The video format currently assigned to lo XT/4K. This is the format that the framebuffer will use and is shown in the Control Panel using the color blue. It is the format that the third-party application software will either receive from the AJA hardware, or is giving to the hardware. All icons in blue are the same as the Primary Format used by the framebuffer. Also any text descriptions in the block diagram that appear in blue indicate that something is in the primary format. For example:

• If the input and output icons are blue, you know that the same format is used throughout the video path. No format conversion is being performed.
• If the input or output icon colors differ (blue input and green output icons for example), you know that a format conversion is being performed.

Secondary Format:

Any format other than the currently selected Primary Format, is a secondary format. As described previously, this means that either the Inputs or Outputs are somehow different from the framebuffer's assigned format—the Primary Format. A conversion is readily apparent because of the color change from blue. In the example below, a secondary format of 720p59.94 is selected on the Format screen and is then used for output at SDI 2.

Figure 23. Setting the Secondary Input Format

NOTE: In some cases the application you use with the Io XT/4K will automatically set the Primary Format, overriding the user's selected primary format in the AJA Control Panel.

Format Conversion:

Conversion allows selection of a format conversion between High-definition and Standard-definition. The choices offered depend on the AJA device present in your system and the Primary and Secondary format selected. Io XT supports up-, down-, and cross- conversion plus SD-to-SD aspect ratio conversions.

Conversion is performed based upon the Primary or Secondary Format settings. Io XT/4K can down-convert the input format (when designated as a Secondary Format) to the selected Primary Format. Or you can assign a Secondary Format for output that will be a conversion from the Primary (frame buffer) format.

NOTE:

When converting an Input to the Primary Format, select the Secondary Format option that has (I), for input only, appended to it. Conversely, when converting an Output from the Primary Format, you must select an output signal with (O) for output only.

Input/Output Icons:

The input and output icons are triangles that together with their color show all the input and outputs and their status (selected, not selected, input present or not, format, etc.). A complete video path is shown when inputs and outputs are connected with lines going to/from the framebuffer.

Figure 24. Input/Output Icon

Conversion Icons:

When an input or output is a different standard than the framebuffer, the lo XT/4K may be up-down- or cross-converting the signal to the selected standard. This may be automatic, because it's detected an input signal that differs from the standard currently selected, or because you've explicitly told it to convert. In either case, the block diagram will show the conversion by displaying a conversion icon in between the input/output and the framebuffer.

Figure 25. Up, Down, and Cross-convert Icons

Control Panel Screens:

The side area of the lo XT/4K Control Panel provides different information categorized by topics. Clicking on a topic—or a block diagram element—displays an information screen corresponding to that topic. Screens that can be selected are:

Control: configures lo XT/4K operation and output timing.

Format: select the framebuffer primary video format and any secondary formats for conversion of inputs/outputs

Input Select: view and edit input selections and how they are mapped

SDI Out: select output format

HDMI: configure the HDMI I/O

Analog Out: configure the component/composite analog output

Video Setup: configures Video such as composite black level and filtering specific video parameters for output.

Audio Setup: (lo XT only) configures Audio options such as analog audio monitor level.

Conversion: (available for Mac only) for applications that support selection of codec

options such as whether paused video appears as a full frame or a single field (jitter shown or not shown) and 24 to 30 fps padding patterns, RGB range, and Stereo 3D signal configuration (if applicable).

DS Keyer: setup and control the insertion of keyed video from the frame buffer or graphics files with alpha channel.

Presets: add or delete saved preset configurations (handy for setting up the lo XT/4K for certain workflows and then saving it as a canned configuration for easy later recall)

Firmware: enables installation of AJA card firmware.

Info: displays status information and firmware version # of the lo XT/4K and how it is installed in the host Macintosh. This information is generally intended for troubleshooting/support.

Control Panel Operation

In this section, Control Panel operation for lo 4K using Ultra-HD and 4K formats are described separately (see "Configuring Quad SDI I/O" on page 48). Standard SD, HD, and 2K operations are essentially the same for both lo XT and lo 4K and are illustrated using lo XT screen shots (exceptions are noted).

Control Screen

The Io XT/4K can be controlled by various software applications running on a host Mac. The Control screen is where you select how the Io XT/4K directs video and is used by application software. This screen also provides control for configuring output timing with regard to external reference video and horizontal/vertical delay.

At the top of the Control screen it will show the current Default Output and the application currently controlling the lo XT/4K.

Figure 26. AJA Control Panel, Control Screen

Control Screen Settings

Default Output—this is where you select what lo XT/4K will output as a default when no application has control of the board, such as when the Finder is active. Since lo XT/4K can be controlled by software applications as well as its own control panel, the output can change dynamically. When you select many video applications, they will grab control of the lo XT/4K inputs/outputs. These settings determine what happens when an application that doesn't grab the lo XT/4K inputs/outputs is active.

Default Output Choices and their meanings:

- Input Pass through: this selection directs Io XT/4K to route video from its selected input through the card for processing and output. When this selection is in effect, all Primary/Secondary Format selections are available for selection in controlling the output. This, in effect, makes the Io XT a converter when used in conjunction with the AJA Control Panel application and your computer. No applications other than the AJA Control Panel need to be open to convert audio and video from one format to another. For example, if an SD source tape needs to be dubbed to an HD tape, the signal might be routed from the SD VTR to the Io XT, configured for up-conversion in the AJA Control Panel and then passed through to the HD VTR for recording.

NOTE: See "Configuring Quad SDI I/O" on page 48 for using this menu to input UHD/4K formats.

- Test Pattern: this selection directs lo XT to output a choice of preset pattern when no other application is using the lo XT. You can choose from:

Black, Color bars (75% or 100%), Ramp, Multiburst, Line Sweep, Multi Pattern, or Flat Field.

In addition to the preset test pattern choices, a "Load File..." selection at the bottom of the menu allows you to load any standard RGB graphics file (.tif,.psd, etc.) into the frame buffer for display.

While in Test Pattern mode, you can select RGB or YUV output via a pulldown menu.

NOTE: The graphic file will not be scaled to fit. If it's smaller than the current frame buffer format, lo XT/4K will center it in the frame. If it's larger than the current frame buffer format, it will be cropped on the right and bottom. Also some graphics formats and bit depths may not be supported. Once a graphic file is loaded into the frame buffer it will be retained until it is overwritten by another graphic or test pattern, or when power is turned off. Graphic file names are only "remembered" in the menu as long as the AJA Control Panel application is running.

Hold Last Application: this selection directs lo XT/4K to hold and output the last frame of video from the last application to control lo XT/4K. This can be helpful when operating in an environment where you're switching back and forth between multiple application windows.

Playback Timing: Use these controls to set Genlock and Timing adjustment.

Genlock (Freerun, Ref In, Video In)—selects how Io XT/4K will synchronize program video:

- Freerun: In this mode, lo XT/4K generates sync without an external reference source

- Ref In: Directs Io XT/4K to use the Ref Video source for sync (usually an analog black burst video signal)

- Video In: Directs lo XT/4K to use whichever video input source has been selected in the Inputs screen for sync

Timing (Horiz and Vert)—these two pull-downs allow output timing adjustment with reference to the Ref Video source selected. The Horizontal reference can be adjusted by selecting a number of pixels (clocks) to offset. Vertical can be adjusted by specifying a number of lines to offset.

Format Screen

The Formats screen shows the video format currently in use by the Io XT/4K framebuffer (called the Primary Format) and allows you to change it. All throughout the Control Panel, choices are always presented based on what Io XT/4K can do with the signals available and the inputs/outputs selected. For example, on the Format screen, if the output or inputs are a different format than the primary, then you'll see an additional information pane that allows you to view and edit the secondary format—including control over whether up/down/cross conversion is employed.

Figure 27. AJA Control Panel, Formats Screen

Format Screen Settings

Video Format (Primary and Secondary):

These pull-down menus show the currently selected formats. If you select an alternate value in the Primary Format using the pull-down, it will change the format used by Io XT's framebuffer. When a change is made via the Video Format pull-down or by right-clicking or Control-clicking an icon and selecting a new format via a contextual menu, the block diagram will change to reflect the new format. In the case of a Secondary Format, the formats available can vary based on what the Primary Format is and the input signal (frame rates of input sources limits the to/from conversion choices). The "Secondary

Video Format" pull-down menu lists all compatible formats for selection (incompatible formats are not shown). This allows you to see what you've chosen, and also see those formats that are compatible with the selected Primary format.

For a complete list of lo XT/4K Formats see "Appendix A: Specifications on page 54".

NOTE: The AJA Control Panel software uses the abbreviation "sf" instead of "psf" when referring to "progressive segmented frame" formats. In the manual and in other literature you may see either of these acronyms used interchangeably. Visually it is easier to discern at a glance if you are working with progressively segmented frame formats (sf in the AJA Control Panel) as compared to progressive frame formats which will show only "p."

Pixel Format: Use this pulldown menu in lo 4K to choose: YUV-10, YUV-8, RGB-10, or ARGB-8

RGB Range: The RGB Range pulldown menu allows you to select either Full range (0-1023) or SMPTE range (typically 64-940) for RGB color output.

VANC Checkbox: When checked ON, the VANC checkbox tells the Io XT/4K to capture and process any ancillary data in the SDI stream. This can include Closed Captioning data, and other types of metadata. Applications such as Premiere Pro and Final Cut Pro will not capture or output this data through the Io XT/4K, if this box is not checked on.

Io XT Cross-conversion: If you have an HD format as your primary and then select a secondary HD format with a different frame size, the Io XT will perform a cross-conversion where necessary (input or output) for "like Hz" formats. "Like Hz" means that 720P 59.94 may be converted to 1080i 29.97 (59.94Hz). Converting from disparate Hz is not supported on the Io XT for cross-conversions. The example below shows 1080i to 720p.

Io XT Up (Conversion): The Up and Down pull-down menus are available when conversion has been selected for the video path to/from the framebuffer and like Hz formats are selected (the one exception is 1080PsF 23.98 which can be down-converted to 525i 29.97.) Different choices will be available depending on the type of conversion and formats being converted. SD to SD conversions are essentially aspect ratio conversions to accommodate transforming anamorphic images to letterbox or vice versa.

For up-conversion the following choices are available:

Anamorphic: full-screen "stretched" image

Pillar box 4:3: results in a 4:3 image in center of screen with black sidebars

Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image with black sidebars

Zoom Letterbox: results in image zoomed to fill full screen

Zoom Wide: results in a combination of zoom and horizontal stretch to fill a 16:9 screen; this setting can introduce a small aspect ratio change

Io XT Down (Conversion): For down-conversion the following choices are available:

Letterbox: image is reduced with black top and bottom added to image area with the aspect ratio preserved

Crop: image is cropped to fit new screen size

Anamorphic: full-screen "stretched" image

Io XT SD to SD: This pulldown is for SD to SD aspect ratio conversion.

Letterbox: this transforms SD anamorphic material to a letterboxed image.

H Crop: will produce a horizontally stretched effect on the image; transforms anamorphic SD to full frame SD

Pillarbox: will produce an image in the center of the screen with black borders on the left and right sides and an anamorphized image in the center

V Crop: will transform SD letterbox material to an anamorphic image

4K to HD Down-conversion:

The lo 4K provides a dedicated SDI Monitor BNC that outputs a quarter-size image of a selected UHD/4K signal format. For details, see "Using lo 4K for UHD/4K" on page 47.

Figure 28. AJA Control Panel, Formats Screen, Example shows lo XT cross-conversion

Input Select Screen

On the Inputs screen you can view the currently selected video and audio input sources and map audio sources to the channels supported by your editing application. Two information panes in the screen are provided: Video Input and Audio Input.

Figure 29. AJA Control Panel, Inputs Screen

Input Select Settings

Video Input:

The pulldown menu allows you to see and change what's currently selected and shows the video format that lo XT has detected (if any). The figure above shows that video is selected at the HDMI input and the format is 1080i with a frame rate of 29.97. Since this text is blue, you can tell that it matches the framebuffer's primary format selected in the "Format" screen. By looking at the input source, you can determine how the primary format should be set (unless you want to perform a conversion on the input.) If you wish to select a different input use the pulldown to select either SDI 1, 2 or Dual Link for two-wire 4:4:4 RGB, or Stereo 3D. For 3G single-link, choose the SDI Source used and select Stereo 3D from the SDI pulldown menu.

Use the LTC/Ref menu pulldown next to Video Input to select how the LTC BNC is used: selecting Reference means it's used a Reference standard; selecting LTC means it's used for linear time code (LTC) input.

System Genlock:

For video stability and proper system operation, you can genlock all equipment to house sync, however genlock is not required for Io XT/4K due to excellent freerun accuracy. To connect genlock, use a black burst generator output looped through the system. On the Io XT/4K house sync is connected to "LTC/Ref In".

NOTE: Be sure to set the Reference/LTC connection to Reference in the pulldown menu in the Video Input pane.

Audio Input:

This pulldown menu allows you to pick where the audio comes from. lo XT/4K supports up to 16 channels of embedded audio. Here you can also select which two channels from the 16 embedded would be mapped to your editing application if only two channels were selected in that application.

SDI Out Screen

The SDI Out screen shows the current settings for the SDI outputs. Because the outputs can be configured independently, one output may be the Primary format and the other output may be the Secondary format. If an input/output has no video, it will be indicated on the block diagram ("No Video").

SDI Output 1 and 2 Configure SDI Out 1 and 2 via pulldowns:

Figure 30. AJA Control Panel, SDI Output Screen

SDI Output Options

Primary: When selected, this indicates that the SDI output is set to the same format as the framebuffer. That value will be listed in blue.

Secondary: When selected, this indicates that the SDI output is set to a format different from the framebuffer (Primary Format). That secondary format value will be listed in green. This shows that active processing of the video is taking place (format change and possibly even up/down-conversion).

Video+Key: When selected, this indicates that the SDI 1 Output video is set to the same format as the framebuffer. SDI 2 Output is set to a video key signal associated with SDI 1 (the shape to be cut out from the video - this will appear as a black and white image/matte). Using the second lo XT output as an Alpha Channel key, with the video output, may be useful for feeding production switchers, DVEs or other professional video equipment.

    E["1080i29.97 SDI Out 2 DL V+K"] --> B

Stereo: When selected, this indicates that SDI 1 represents the left eye output and SDI 2 represents the right eye output of stereoscopic material. Io XT also offers single link 3Gb output of multiplexed Stereo 3D.

Dual Stream Options

Dual Link: Output (SMPTE 372M) using SDI 1 and SDI 1 in concert.

3Gb: Output (SMPTE 424M) using a single-link transport.

RGB SMPTE: When selected, sets the output to RGB SMPTE range video for the SDI output.

RGB Full: When selected, sets the output to RGB full range video for the SDI output.

HDMI Screen

The Io XT/ 4K HDMI input and output are configured at this screen. For Io 4K UHD and 4K format setup, see "HDMI Screen in 4K Mode" on page 50.

Figure 32. AJA Io XT HDMI, HDMI Screen

HDMI Output Settings The Source pulldown menu allows you to select either the primary video format (framebuffer) or (if conversion is supported) a secondary one (up/down/cross-conversion).

Pulldowns are also provided for configuring the video output range, color space and number of embedded audio channels (2 or 8) for the HDMI output. A Protocol pulldown allows you to choose either "HDMI" or "DVI" protocol—use DVI if you're outputting to a DVI monitor using an HDMI to DVI adapter.

A pulldown menu for 3D output allows you to select either Side-by-Side or Top-Bottom (Stacked) output of left-eye and right-eye signals.

NOTE: This selection must agree with format selection in the third-party CineForm Codec (NOT included with AJA lo XT) pulldown menu.

Audio Channels: An Audio Channel pulldown allows you to select the number of embedded audio channels for the HDMI output.

HDMI Input Settings The detected HDMI input video format is displayed and you're given a chance to configure the RGB range (SMPTE or FULL) and select any two embedded channel pairs from those supplied for stereo output (if applicable).

Analog Out Screen (Io XT Only)

Io XT provides a high-quality analog component or composite + Y/C output, generally used for monitoring. This screen shows the current settings for that analog output, and allows you to re-configure it when desired.

Figure 33. AJA Control Panel, Analog Out Screen

Analog Out Screen Settings

Analog Output:

Select Primary or Secondary (any conversion applied) for the analog output; if a conversion is applied, you'll see the conversion icon appear on the block diagram. Next, select the video format from the Format pulldown.

Analog formats can be:

Composite +Y/C (one composite output and a simultaneous Y/C [S-Video] output)

Component (SMPTE/EBU N10)

Component (Beta)

Component (RGB)

Audio Monitor:

Here you select which two channels will be mapped to the analog audio stereo output (headphone jack).

Video Setup Screen

Io XT provides standard setup adjustments for analog component or composite output. This screen shows the current settings for that analog video output, and allows you to reconfigure it when desired.

Figure 34. AJA Control Panel, Video Setup Screen

Setup Screen Settings

Analog Black Level (in lo XT only):

Choices available for Black Level are the two Composite analog formats. Choices presented are for US or Japan:

• 7.5 IRE (NTSCUS)
• 0 IRE (NTSC Japan)

Progressive Formats:

Radio buttons allow you to choose between psf (progressive segmented frames) and p (progressive frames) non-interlaced output.

QuickTime Video Output Filter (available on Mac OS only):

The QuickTime Video Output Display Filter is designed to help manage the comprehensive list of video outputs that may be available to applications.

By selecting the checkbox next to specified parameters, the video outputs related to these specified parameters are enabled as possible video outputs for applications. For example, if the checkbox next to 25/50 is unchecked, 50Hz video outputs are deselected and would not be available to the user's editing application. To avoid confusion when working in a particular editorial environment, you might choose to leave 50Hz unchecked if working solely in a 60Hz editorial environment. The same might be true if you do not intend to work with true progressive 1080 material.

Audio Setup Screen (Io XT Only)

This screen shows the current settings for the analog audio output, allowing you to reconfigure it when desired.

Figure 35. AJA Control Panel, Audio Setup Screen

Audio Setup Screen Settings

Lock Audio Gain To Unity:

When set, the lo XT will ignore the third-party application's gain setting and set the audio gain at unity. When not set, this checkbox tells the lo XT to get the audio gain setting from the editing application (if supported).

Analog Audio Monitor Level:

This selection determines the audio level that will appear at the analog audio outputs ("FSD" is full-scale-deflection reading as measured on a VU meter). Select +18 for Europe or +24 for USA.

Conversion Screen (Mac OS only)

This screen offers controls that determine how the card behaves with 3rd-party applications.

NOTE: This screen is present in the Mac version of AJA Control Panel only and not all applications support these functions.

Figure 36. AJA Control Panel, Conversion Screen

Pause On:

These two choices determine what happens when the editing application is paused in stop mode:

Full Frame: both fields are displayed resulting in some jitter while paused.

Single Field: a single field is displayed, showing no flicker (useful when color correcting or whenever the flickering would be a distraction).

Software Conversion:

The value selected in this pulldown is used whenever, due to format selection, you've chosen to do 24 frames-per-second to 30 conversion where extra fields will be added to pad the existing ones. Depending on video content, selection of different field patterns may be useful in reducing jitter due to the content of adjacent fields. The numbers in the pattern choices specify the frequency with which inserted fields will be repeated. For example, "2:3:2:3" means duplicate a field twice, then the next field three times, then the next twice, and then back to three times.

Figure 37. Conversion Screen Frame-padding Pattern Choices

YUV-RGB Conversion

These pulldowns select industry standard color space and gamma transfer functions for the YUV-RGB conversion, or allow you to direct lo XT to automatically determine it for you.

Colorspace: Choose from:

Gamma: Choose from the following:

• Linear (1.8)
• Rec 601 (2.20)
• Rec 709 (2.22)
• Auto

Enable Custom LUTs: This checkbox enables a custom color lookup table (LUT).

DS Keyer Screen

The Io XT and Io 4K have a hardware-based downstream keyer that is ideal for putting logos, "bugs" or other video material with an alpha channel on top of video being played out or printed to tape.

NOTE: The Io 4K does not support Downstream Keying in UHD and 4K formats.

A typical application would be putting a television station's call letters or channel over program video content. Keyed video can be from the lo XT internal Frame Buffer (from storage, video In, etc.) or from a graphics file that has an alpha channel (PhotoShop etc.).

Figure 38. AJA Control Panel, Downstream Keyer Screen

Settings in the DS Keyer Screen provide control over how the keyer operates and whether it's turned on or off. Controls and their meanings in the screen are as follows:

Mode

Downstream Keyer Off: When this pulldown menu item is selected the downstream keyer will be turned off

Frame Buffer over Matte: Places the keyed video with alpha channel currently in the Frame Buffer over a fixed color matte determined by the "Matte Color" setting set separately.

Frame Buffer over Video In: Places the keyed video currently in the Frame Buffer over the video input for playout or print-to-tape.

Graphic over Matte: Places a graphics file having an alpha channel (chosen in "Graphic File" pulldown) over a fixed color matte determined by the "Matte Color" setting set separately.

Graphic over Video In: Places a graphics file having an alpha channel (chosen in "Graphic File" pulldown) over the video input for playout or print-to-tape.

Graphic over Frame Buffer: Places a graphics file having an alpha channel (chosen in "Graphic File" pulldown) over the current contents of the lo XT Frame Buffer (which might be from storage, video In, etc.).

Matte Color

Only available when the pulldown "Frame Buffer over Matte" or "Graphic over Matte" are selected-pressing this button brings up a color selection dialog. The dialog provides a variety of ways to select a matte color including a color wheel, color picker (choose from a location anywhere on the computer screen), numeric sliders, swatches, "crayons", and spectrums. The matte chosen will be used as a video background under the keyed video.

Foreground pre-multiplied (checkbox)

Use to avoid "matte lines" and improve the appearance of the foreground (key) being composited over the background.

Audio Out

Frame Buffer: Select audio out to be routed from the Frame Buffer.

Audio In: Select audio out to be routed from the Io XT's selected input(s).

Graphic File

This pulldown allows you to choose from any recently accessed file or select a new file ("Load File..."), which then brings up a file dialogue. Remember that the file raster (pixel x pixel count) should match the primary format in the frame buffer or the secondary format if up-converting. Example: you wish to key a logo on top of your 1920x1080 footage, the still image with alpha channel that you load should be 1920x1080.

Timecode Screen The Timecode input:

• Selects the timecode stream read for applications that use it (for example, AJA Control Room, when the timecode source is set to "Use control panel setting," will read the selected stream)
• Is used for monitoring the RP-188 timecode embedded in the digital data stream
• Is used for selecting a timecode offset (if required)

In RP-188 timecode (SMPTE 12M-2) there can be multiple timecode types in the data stream. Use this pull-down to select the one you wish to monitor:

• RP188 LTC (Linear timecode)
• RP188 VITC 1 (Vertical Interval timecode)
• RP188 VITC2
• LTC Port input

The selection will be displayed in the timecode value displayed to the right of the pull-down.

User Bits:

For monitoring a variable framerate (VFR) timecode (such as Varicam), you may wish to check the User-bits box. If you set this checkbox, Io XT/4K will detect and interpret the user-bits and display them next to the checkbox. You will see the original framerate (30 fps in the figure below) followed by the adjusted frame padding (two digits reporting discarded and retained frame padding).

NOTE: SMPTE 12M-2 is the updated name and specification for what was RP-188.

Figure 40. AJA Control Panel, Timecode Screen

Timecode Output Settings

Use QuickTime Timecode (Mac OS Only):

Timecode Burn-in:

This feature is for Final Cut Pro 7 (or earlier), VTR Exchange, and AJA TV only. When checked, it directs lo XT/4K to output timecode from the QuickTime timecode track.

This pulldown selects whether the timecode value is displayed in a "burned-in" window in video output. If set to "OFF", timecode will not be keyed over the video. If set to "Timecode", then the timecode value will be keyed over the output video for all of the Io XT/4K outputs. This can be useful for synchronizing, choosing edit points, dailies, and many other purposes.

Timecode Offset (entry field and FPS pull-down):

When QuickTime timecode in disabled, this text entry field allows you to generate a timecode based on the offset entry. You can select a framerate from the pulldown menu at the right side of the pane. Use that same value here as the source video to ensure the timecode is synchronized.

NOTE:

SMPTE RP 188 defines a standard for the transmission of time code and control code in the ancillary data space of a digital television data stream. Time code information is transmitted in the ancillary data space as defined in ANSI/SMPTE 291M. Multiple codes can be transmitted within a single digital video data stream. Other time information, such as real time clock, DTTR tape timer information, and other user-defined information, may also be carried in the ancillary time code packet instead of time code. The actual information transmitted through

the interface is identified by the coding of a distributed binary bit. Equipment manufacturers can use the meta data for different purposes.

Presets Screen

After configuring the AJA Control Panel screens, you can then save all your settings as a snapshot for later recall—called a preset. In this way, you can organize presets for all your typical tasks, eliminating time-robbing manual reconfiguration each time. To save a preset, simply go to the Presets screen and click "Save Preset". A dialog will be presented asking you for a name; enter a meaningful name and click "OK". Thereafter the preset will be available under the Control Panel "Presets" list.

Figure 41. Presets Screen

Transferring Saved Presets:

From the Presets screen you can manage your collection of presets easily. To Load or Delete a stored preset, just select it with your mouse and then click the "Load Preset" or "Delete" button respectively.

If you want to use a saved Preset on another workstation, you can simply copy the file on removable storage and install it at the new location. The Preset file is always stored at:

• \~/Library/Application Support/AJA/ Presets/ [on Mac]
  • c:\Users\\AppData\Local\AJA\Control Panel\ Presets\ [Windows 8]

Reset to Default:

When you click the 'Reset to default' button the control panel will delete the User's preference file and do one of the following:

A. If "Shared" preferences exist, they are reloaded and the device is set to this state.
B. If the "Shared" preferences file does not exist, "factory defaults" are loaded and the device is set to this state.

For more information on Preset preferences see "Single-user & Network Settings" on page 23.

Using lo 4K for UHD/4K

In 4K Mode, you can input or output four channels of video representing individual quadrants of Ultra-HD (3840x2160) and 4K (4096x2160) formats. The Io 4K employs all four bi-directional SDI connectors for either input or output It cannot support the input and output at the same time.

Physical connections of the quadrants will be mapped to the Io 4K SDI connectors as shown in the following screens. For the HDMI, you can choose full, quarter, or one of the quadrants for viewing (see "HDMI Screen in 4K Mode" on page 50 HDMI output selection).

Configuring Quad SDI I/O

This section describes the AJA Control Panel operations specific to UHD/4K Format selection.

Output Configuration:

When you use the Control Panel Format screen to select a UHD or 4K format for the lo 4K output, you must also make sure the default output mode (Control screen setting) is set to "Test Pattern." Then the SDI connectors 1–4 will automatically configure as outputs (see Figure 46).

Figure 45. Control Screen setting for 4K Output

NOTE: When you select a UHD/4K format, the HDMI monitor output can be set to Full (shown below) or will display the Output Mode selection icon (as shown on the SDI Mon output) when a quarter or quadrant output signal is selected (see "HDMI Screen in 4K Mode" on page 50 for output options).

Chapter 4: Troubleshooting

If You Run Into Problems

One useful way to find the source of problems is to isolate your system to the smallest size where the problem still occurs and then note all the symptoms. This serves to eliminate areas not involved in the problem and makes finding the problem easier.

Once you've noted problem symptoms, look through the following table and see if any of the symptoms are listed. If so, check the items listed. If you later need to call for customer service, let them know all of the things you've tried and when and how the symptoms appeared.

Symptom Check
Disk RAID cannot keep up (dropped frames etc.).	Ensure the disk system is providing at least 50 MB/second sustained transfer rate
Dropped frames during playback. 1. Virus checking software running in the background (disable it).2. Scratch drive not set to the RAID.
Dropped frames during record. 1. RAID cannot sustain the data rate of the capture preset codec.2. Virus checking software running in the background (disable it).3. Scratch drive not set to the RAID.
Media is not being captured from desired external device.	Check the settings in the Input screen of the lo XT Control Panel application. Also check equipment cables.
Dropped frames during playback Look for scroll bars in the viewer or canvas as a warning sign that the zoom setting exceeds the fit-t-window.
Video stutter during playback. RAID cannot sustain data rate.
Red render bar occurs when placing a clip on a sequence.	The sequence setting does not match the clip setting.
