Cisco TelePresence System Quick Set C20 and Profiles using C20
Contents Introduction
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: Video Input DVI 2 Type: AutoDetect
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: <On/Off>
On: Let the system automatically adjust aspect ratio.
Off: No adjustment of the 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 ScaleToFrameThreshold configuration (in percent), the image is stretched
to fit. If not, the system will maintain the original aspect ratio.
MaintainAspectRatio: Will maintain the aspect ratio of the input source, and fill in black in the
rest of the frame (letter boxing or pillar boxing).
StretchToFit: Will 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 ScaleToFrame configuration 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 configuration (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>
Example: Video Layout ScaleToFrameThreshold: 5
Video SelfviewPosition
Select where the small selfview PiP (Picture-in-Picture) will appear on screen.
Requires user role: ADMIN
Value space: <UpperLeft/UpperRight/LowerLeft/LowerRight/CenterRight>
Example: Video SelfviewPosition: LowerRight
Video Layout LocalLayoutFamily
Select which video layout family to be used locally.
Requires user role: ADMIN
Value space: <Auto/FullScreen/Equal/PresentationSmallSpeaker/
PresentationLargeSpeaker>
Example: Video Layout LocalLayoutFamily: Auto

Password protection
Range: Select a value from 0 to 100 percent.
UpperLeft: The selfview PiP will appear in the upper left corner of the screen.
UpperRight: The selfview PiP will appear in the upper right corner of the screen.
LowerLeft: The selfview PiP will appear in the lower left corner of the screen.
LowerRight: The selfview PiP will appear in the lower right corner of the screen.
CenterRight: The selfview PiP will appear in to the right side of the screen, in center.
Auto: The default layout family, as given by the layout database, will be used as the local layout.
For more information about the layout database, see the xCommand Video Layout LoadDb
command.
FullScreen: The FullScreen layout family will be used as the local layout.
Equal: The Equal layout family will be used as the local layout.
PresentationSmallSpeaker: The PresentationSmallSpeaker layout family will be used as the local
layout.
PresentationLargeSpeaker: The PresentationLargeSpeaker layout family will be used as the local
layout.
