The following table summarizes the Maximum Resolution of Content and Frames per Second (fps) for Bit
Rate Allocations to the Content Channel.
SVC Only and Mixed CP and SVC Content Setting
The Content channel is transmitted in Graphics mode only.
Content Protocols
Two Content Protocols can be used for sharing content:
●
H.263 (CP and mixed CP and SVC)
●
H.264 (all conferencing modes)
H.264 offers higher quality content, but is not supported by legacy endpoints. Depending on the endpoints
capabilities, you can determine the content sharing experience by selecting the appropriate protocol and
system behavior from the Content Protocol list:
●
H.263 & H.264 Auto Selection (AVC CP Only)
●
H.263 (AVC CP Only)
●
H.264 HD (AVC CP Only)
●
H.264 Cascade and SVC Optimized (all conferences)
