Jumpy Video
Problem   
The video display appears to be unstable.
Possible Cause   
When the Cisco Unified MeetingPlace 
 is set to standard rate, and 
and video terminals are using the H.264 codec, Cisco Unified MeetingPlace negotiates the video 
connection at 15 frames per second, which is consistent with the H.264 Level 1.2 specification. 
However, many video terminals ignore the frame rate limitation for H.264 Level 1.2 and send frames 
at a higher rate. This overloads the Cisco Unified MeetingPlace video blade and results in corrupted 
video output. Note that the effect may be observed on terminals other than the one causing the 
problem.
Solution   
Identify suspect terminals and check with the endpoint vendor for a firmware update. 
Solution   
Set the Cisco Unified MeetingPlace 
 to high rate, or configure the video 
terminals to use H.263 instead of H.264.
