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.
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
HD VSW Guidelines
• The display aspect ratio is 4x3 or 16x9.
• Site names, skins, etc... are not supported in HD Video Switching.
• Video forcing is enabled at the conference and participant levels.
• Endpoints that do not support HD or are unable to meet these
requirements connect as Secondary (audio only).
High Definition Video Switching conferencing mode is unavailable to ISDN
participants.
