Chapter 2-Additional Conferencing Information

High Definition Video Switching

High Definition Video Switching enables compliant endpoints to connect to conferences at resolutions of 1280x720 pixels (720p) at line rates ranging from 384kbp to 4Mb and 1920 x 1080 pixels (1080p) at line rates ranging from 384kbp to 6Mbps (with MPM+). Video display is in full screen mode only and video is switched to the speaker.

HD Video Switching uses less system resources than HD CP: only one CIF video resource per participant for HD resolution.

The supported conference size is up to 80 video participants and 120 voice participants.

High Definition Video Switching conferences require:

All participants to have HD compliant endpoints.

All participants to connect using the same conference line rate.

High Definition Video Switching conferencing mode is unavailable to ISDN participants.

The recommended number of connections at HD1080p resolution in an RMX 2000 with two MPM+ cards/RMX 4000 with four MPM+ cards is:
