Video Switching - Polycom RMX 1500 Administrator's Manual

Video Switching

Table 2-5
In Video Switching mode all participants see the same video picture (full
screen). The current speaker is displayed in full screen on all the
participants' endpoints, while the speaker sees the previous speaker.
Switching between participants is voice-activated; whenever a participant
starts to speak, he or she becomes the conference speaker and is viewed
on all screens. All conference participants must use the same line rate and
video parameters such as video protocol, frame rate, annexes and
interlaced video mode as no video processing is performed. Compliant
endpoints can connect to conferences at the following resolutions:
• H.264 1080p30
• H.264 720p30
• H.264 720p60
• H.264 SD 30
Video Switching uses less system resources than CP: only one CIF video
resource per participant for HD resolution. Table 2-5 lists the resources
available to VSW conferences by line rate and card type.
VSW Resource Capacity Line Rate

Capacity numbers are for maximum capacity card assemblies. These numbers
may be lower when LPR and/or encryption are enabled.
The maximum supported video conference size is 160 participants.
Video Switching conferences require:
• All participants to have HD compliant endpoints.
• All participants to connect using the same conference line rate.
Video Switching conferencing mode is unavailable to ISDN participants.
