Video Input DVI [1] Type

The official DVI standard supports both digital and analog signals. In most cases the default

AutoDetect setting can detect whether the signal is analog RGB or digital. However, in some

rare cases when DVI-I cables are used (these cables can carry both the analog and digital

signals) the auto detection fails. This setting makes it possible to override the AutoDetect and

select the correct DVI video input.

Requires user role: ADMIN
Value space: <AutoDetect/Digital/AnalogRGB/AnalogYPbPr>

AutoDetect: Set to AutoDetect to automatically detect if the signal is analog RGB or digital.
Digital: Set to Digital to force the DVI video input to Digital when using DVI-I cables with both

analog and digital pins and AutoDetect fails.
AnalogRGB: Set to AnalogRGB to force the DVI video input to AnalogRGB when using DVI-I

cables with both analog and digital pins and AutoDetect fails.
AnalogYPbPr: Set to AnalogYPbPr to force the DVI video input to AnalogYPbPr, as the

component (YPbPr) signal cannot be auto detected.

Example:

Video Input DVI 1 Type: AutoDetect

Video ControlPanel Brightness

Set the brightness level for the Touch controller.

Requires user role: ADMIN
Value space: <0..100>

Range: Select a value from 0 to 100.

Example:

Video ControlPanel Brightness: 100

Video Layout Scaling

Define how the system shall adjust the aspect ratio for images or frames when there is a

difference between the image and the frame it is to be placed in.

Requires user role: ADMIN
Value space: <Off/On>

Off: No adjustment of the aspect ratio.
On: Let the system automatically adjust aspect ratio.

Example:

Video Layout Scaling: On

Video Layout ScaleToFrame

Define what to do if the aspect ratio of a video input source doesn't match the aspect ratio of

the corresponding image frame in a composition. For example if you have a 4:3 input source

(like XGA) to be displayed on a 16:9 output (like HD720).

Requires user role: ADMIN
Value space: <Manual/MaintainAspectRatio/StretchToFit>

Manual: If the difference in aspect ratio between the video input source and the target image

frame is less than the Video Layout ScaleToFrameThreshold setting (in percent), the image is

stretched to fit. If not, the system will maintain the original aspect ratio.
MaintainAspectRatio: Maintain the aspect ratio of the input source, and fill in black in the rest

of the frame (letter boxing or pillar boxing).
StretchToFit: Stretch (horizontally or vertically) the input source to fit into the image frame.

NOTE: The general limitation is that you cannot upscale in one direction and at the same

time downscale in the other direction. In such situations the codec will apply letterboxing.

Example:

Video Layout ScaleToFrame: MaintainAspectRatio

Video Layout ScaleToFrameThreshold

Only applicable if the Video Layout ScaleToFrame setting is set to manual. If the difference

in aspect ratio between the video input source and the target image frame is less than the

ScaleToFrameThreshold setting (in percent), the image is stretched to fit. If not, the system will

maintain the original aspect ratio.

Requires user role: ADMIN
Value space: <0..100>

Range: Select a value from 0 to 100 percent.

Example:

Video Layout ScaleToFrameThreshold: 5

Video Selfview

Determine if the main video source (self view) shall be displayed on screen.
This setting is obsoleted by the Video SelfviewDefault Mode setting as from TC6.0.

Requires user role: USER
Value space: <Off/On>

Off: Do not display self view on screen.
On: Display self view on screen.

Example:

Video Selfview: On
