5 The OSD Menu

The VP-461 OSD menu lets you set the operation parameters for the:

• Main Window Control
• PIP Window Control
• Entire System Control

The nature of the operation setup appears in the OSD title, as shown in the example in Section 5.1:

• The title line shows the control mode (Main, PIP or Entire system)
  • Level 1 lists the main menu items
• Level 2 includes the second hierarchy level, below level 1
• Level 3 includes the third hierarchy level, below level 2
• Function, is the selectable parameter or numerical value and can appear either under level 2 or 3

5.1 OSD Menu Operation Example

In the example illustrated below, the Master Connection is set to PC (see Section 5.7).

The table below shows function 632 (from the Protocol in Section 10.2.2):

• 6 in the hundreds, represents “Scale” which is the 6^th menu item in the main menu list
• 3 in the tens, represents "Output" which is 3^rd in the Scale menu
• 2 in the units, represents "Master Connection" which is second in the Output menu

Level 1	Level 2	Level 3	Level 4 (Function)	Range	Function
Scale (6)	Output (3)	Master Connection (2)	HDMI	0	632
			PC	1

The subtitle, below the title line shows the current level accessed (Scale in this example)

After selecting Output (which is the second Level), it appears in the subtitle

Once Master Connection is selected, the Title changes to "Entire System Control" indicating that the selection will affect the entire system. The subtitle shows the current, Level 3, selection and the menu list shows the function (PC)

If the display layout includes a PiP window, you can set the OSD menu to control the main source window and the PIP window separately (by defining Window Control, see Section 5.8).

General characteristics which apply to the entire system (for example, setting the volume) are changed without needing to shift control (the title line will state: Entire System Control).

Note that:

• A selected parameter that turns gray becomes valid immediately (there is no need to press Enter to save the changes)
• Exiting the menu saves the parameter to the memory
• Data is saved per window and per input (to a dedicated input + window memory), as applicable

The control buttons let you control the VP-461 via the OSD menu. Press the:

- MENU button to enter the menu, exit the menu, and when in the OSD menu, move to the previous level and change menu settings in the OSD screen. Changes are immediate

The default timeout is set to 30 seconds and can be changed (see Section 5.8)

• ENTER (or ▷) button to access sub-menu items
• Arrow buttons to move through the OSD menu
• Up or down arrows to change settings

Note that when exiting menu, all the changes are automatically saved to the non-volatile memory.

The default OSD timeout is set to 30 seconds and can be changed (see Section 5.8).

5.1.1 OSD Control Icons

The following three icons: M, P, and E are included to indicate when functionality applies to the Main window, the PiP Window or the entire system:

• for Main Window Control
• for PiP window Control
• for Entire System Control

5.7.1 Selecting the Correct Aspect Ratio

You can configure the aspect ratio of any output image to fit your application. The VP-461 offers four different aspect ratio settings: Follow Input, Follow Output, Best Fit and Letterbox. Here is how each of these settings works.

FOLLOW INPUT – The aspect ratio and resolution of the input video or graphics signal are both preserved (no scaling). For example, a composite video image with a 4:3 aspect ratio will appear with the same aspect ratio on a 1080p (16:9) output image, surrounded by black bars

Black-and-white exterior view of a grand public square with central fountain and surrounding buildings (no visible text or signage)

FOLLOW OUTPUT – The aspect ratio and resolution of the input signal is re-sized to precisely match the aspect ratio and resolution of the VP-461 output signal. This may result in some distortion to the input signal images

Exterior view of a grand fountain complex with multiple fountains and surrounding architecture (no signage or text visible)

BEST FIT – This setting re-sizes the video or graphics input signal to "best fit" the output resolution while maintaining the aspect ratio of the input signal. For example, a composite video signal (4:3 aspect ratio) will "best fit" to the top and bottom of a widescreen output image, resulting in black pillars on either side.

Black-and-white exterior view of a grand palace with symmetrical gardens and central towers (no visible text or signage)

LETTERBOX – This setting compresses the top and bottom edges of the input signal, but fills the width of the screen. For example, to preserve a widescreen film image on a 4:3 display.

Exterior view of a grand palace with fountains and manicured gardens (no signage or text visible)

5.7.2 Master Connection Settings

The Master Connection (HDMI or PC) is usually set to the main output display so that the optimal resolution for that display can be obtained.

By setting the output resolution to Native, the VP-461 is triggered to read the EDID of the main display and change the output resolution value according to the native resolution of the display.

If it is not supported by the selected Master Connection, the system searches for the best supported resolution. If the search fails (for example, if the master connection is disconnected or EDID is unreadable), the resolution will default to XGA.

5.8.1 The Luma Keying Feature

The luma keying feature is an easy-to-use method of compositing two video sources into a single image. By setting up a “key” image or clip on a black background, it can be merged – or overlaid – onto the primary video. The key image is transparent in the areas of its dark background, resulting in a picture which looks as if the key image is cut out and pasted over the primary image. This useful function of combining images from two different sources is suitable for many applications, such as sub-titling, labeling, advertising or logo insertion.

To apply the luma keying feature, first set the PiP window to the desired size and location and then turn luma keying On. The PiP image will show without its background.

The lower the luminance in the PIP window, the more transparent it becomes, thus letting the main window image show. The higher the luminance, the less transparent it becomes, not letting the main window show through. To use this feature it is recommended to set the PIP image as follows: use low-luminance colors for the background (the key image portion) and high-luminance colors for the logo.

For certain displays, the screen may flicker once for about a second after activating or changing the luma keying setting.

Since luma keying is a volatile parameter, it may reset unexpectedly following a change in the setup. So we recommend that you activate it after completing the setup.

When the luma keying feature is On, any change in the setup (either by the user or by resetting due to a setup change) may cause the screen to flicker once. The luma keying will recover automatically after resetting.

6 The Display Modes

The VP-461 can function in the single window display mode (the factory default setup) or the dual window display mode.

6.1 The Single Window Display Mode

The single window mode shows one window on the screen. The window size can be customized, and its parameters modified via the OSD menu.

6.1.1 Activating the Single Window Mode

Set the VP-461 to the single window display mode in any of the following ways:

• Press and hold (for 3 seconds) the illuminated front panel PIP button until the button no longer illuminates
• Access the OSD menu, select INPUT>Display Mode, and then choose Single Window
• Press the PIP window on the remote control transmitter (see Section 7.4)

6.2 The Dual Window Display Mode

The VP-461 dual window mode feature lets you show two images on one screen: the main window and the PiP window. For example, you can show a live video window on top of a graphic background, or show two images on screen of the same input channel. The PiP window appears even if no input signals are connected. In this case the PiP window appears in dark gray and the main window appears in light gray.

The dual window mode appears in the following preset PiP configurations:

Picture-in-Picture, with a smaller PiP window superimposed over a full main window image

Illustration of a colorful bird perched on a branch with an inset image of a giraffe in a savanna setting (no text or symbols)

Picture + Picture, where both images appear side-by-side and the aspect ratios of both images are maintained

Illustration of a colorful bird perched on a branch with an insect, alongside a separate image of a giraffe in a grassy field (no text or symbols)

Split, where both images are placed side-by-side with the same height

Split image showing a colorful bird in flight and a giraffe in a savanna landscape (no text or symbols)

The window customization feature (see Section 5.2) lets you customize the dual window mode layout (main window and PiP window) to any size.

You can superimpose any input type over any or the same input type except for HDMI over PC or PC over HDMI

If the HDMI signal is HDCP protected, it can appear on the HDMI output that is connected to a supported HDCP compliant display. However, it cannot appear on a display that is not HDCP compliant and will show a black screen instead.

10 The VP-461 RS-232 Communication Protocol

The Kramer Protocol lets you control the VP-461 from any standard terminal software (for example, the Windows ^® HyperTerminal Application).

10.1 Using the Communication Protocol

There are three different methods to control the VP-461 via RS-232:

• Protocol commands (via protocol 3000) mimicking the OSD, see Section 10.2
• The button functions mimicking the remote controller buttons (as well as the front panel buttons), see Section 10.3
  • Protocol 3000 common commands, see Section 10.4

All three tables together include all the protocol commands, but they are not identical and do not always include the same information.

Some of the data may appear in one or two of the tables but not in the third table and vice versa.

The protocol 3000 communications protocol uses a data rate of 115200 baud, with no parity, 8 data bits, and 1 stop bit.

10.2 Communication Protocol: Mimicking OSD

The audio/video protocol commands defines all the function numbers, their valid parameters can be used with protocol 3000.

10.2.1 Using the Communication Protocol with Protocol 3000 (the "Y" Command)

Set Command:

Type in: "Y Control_Type=0,Function,Param"

Reply: "\~id=01Y Control_Type=0,Function,Param OK"

Set command example, set window control (721) to PiP:

Send: "#y 0,721,1"

Reply: "\~01@Y 0,721,1 OK"

Get Command:

Type in: "Y Control_Type=1,Function"

Result: "\~id=01Y Control_Type=1,Function,Param"

Get command example: get window control setup (721):

Send: "#y 1,721"

Result: "\~01@y 1,721,1"

You can add a last parameter, to be located fourth in SET or third in GET, to define a specific window.

For example:

Set H Sharpness value to 10 on the PiP window (1): “#y 0,510,10,1” Get H sharpness of the Main window (0): “#y 1,510,0”

The “Y” command also supports the value increment/decrement of any command using the ‘+’ or ‘-’ signs as the third parameter of the “Y” command.

For example, move the PiP window one step to the left

Send: "#Y 0,141,-,1"

Reply: "\~01@Y 0,141,-,1 OK"

For example, in order to increase zoom on the main windows type "#Y 0,650,+,0"

Send: "#Y 0,650,+,0"

Reply: "\~01@Y 0,650,+,0 OK"

10.2.2 Protocol Table: Mimicking OSD

You can associate a function number to its description and valid parameters intuitively by navigating the OSD menu according to the following logic: A function number is directly related to its location in the OSD menu.

For example, the third menu on the OSD is Process (3 in the hundreds). The second menu item in Process is Film Mode (2 in the tens), therefore the function number for it will be 320 ( 3^rd item on the Main Window Control and the 2^nd item in the Process submenu (see also Section 5.1). When navigating in the OSD MENU you will be able to see the Film Mode valid parameters.

The following table defines the protocol commands:
