Cisco TelePresence System Codec C90 and Profile 65" Dual using C90
Contents Introduction
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>
Range: Select a value from 0 to 100 percent.
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>
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.
Example: Video SelfviewPosition: LowerRight
