Video Switching

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:
