Video Layout in Cascading CP Conferences

Cascade links are treated as endpoints in CP conferences and are allocated resources

according to "Default Minimum Threshold Line Rates and Resource Usage Summary" on

page 1-135. Cascaded links in 1x1 video layout are in SD resolution.

When cascading two conferences, the video layout displayed in the cascaded conference is

determined by the selected layout in each of the two conferences. Each of the two

conferences will inherit the video layout of the other conference in one of their windows.

To enable the connection of the links between cascaded conferences, they must run at

the same line rate.

To enable Content sharing between the RMX and the MGC, the rate allocated to the

content must be identical in both conferences. Make sure that the line rate set for both

conferences, and the Content Settings (Graphics, Hi-res Graphics or Live video) are

selected correctly to ensure the compatible rate allocation. For more details on the RMX

rate allocation to the Content channel, see "SIP BFCP Content Capabilities" on page 3-2.
