Cisco TelePresence System Codec C20
Contents Introduction
xConfiguration Video Input DVI [2] 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>
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.
example: xConfiguration Video Input DVI 2 Type: AutoDetect
xConfiguration 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: xConfiguration Video Layout Scaling: On
xConfiguration 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.

xCommand
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: xConfiguration Video Layout ScaleToFrameThreshold: 5
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: xConfiguration Video Selfview: On
Select where the small self view PiP (Picture-in-Picture) will appear on screen.
This setting is obsoleted by the Video SelfviewDefault PIPPosition setting as from TC6.0.
Requires user role: ADMIN
Value space: <UpperLeft/UpperCenter/UpperRight/CenterLeft/CenterRight/LowerLeft/
LowerRight>
UpperLeft: The self view PiP will appear in the upper left corner of the screen.
UpperCenter: The self view PiP will appear in the upper center of the screen.
UpperRight: The self view PiP will appear in the upper right corner of the screen.
CenterLeft: The self view PiP will appear on the left side of the screen, in center.
CenterRight: The self view PiP will appear on the right side of the screen, in center.
LowerLeft: The self view PiP will appear in the lower left corner of the screen.
LowerRight: The self view PiP will appear in the lower right corner of the screen.
example: xConfiguration Video SelfviewPosition: LowerRight
