Video Switching

2-24
• High Profile - Endpoints that support H.264 High Profile connect at
these minimum threshold bit rates.
Although the default minimum threshold bit rates provide
acceptable video quality, the use of higher bit rates usually results in
better video quality.
Base Profile / High Profile Resolution Slider Panes
The Base Profile and High Profile sliders operate in the same manner as that
described for the Sharpness and Motion sliders. For more information see
the example in the section: "Sharpness / Motion Resolution Slider Panes" on
page 2-20.
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
