High Definition Video SwitchingHigh 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.
The recommended number of connections at HD1080p resolution in an
RMX with two MPM+ cards is:
• 160 participants at line rates of up to 2Mbps
• 80 participants at line rates of up to 4Mbps
• 40 participants at line rates of up to 6Mbps
