Figure 2-1 AVC Continuous Presence (CP) video streams and built layouts
Video quality in Continuous Presence conferences is affected by the conference line rate
(that determines the maximum line rate to be used by the connecting endpoints), and the
video capabilities of the endpoints such as the video protocol, video resolution and frame
rate. Content sharing is available in all CP conferences.
This requires extensive processing of the video sent to each participant in the conference.
The higher the video rate and resolution, the more processing power is required.
By default every conference, Entry Queue and Meeting Room has the ability to declare the
maximum CP resolution as defined for the system. This includes conferences launched by
the Collaboration Server Web Client and conferences started via the API.
CP conferencing is defined in the Conference profile by settings the following main features:
• Setting the Conferencing Mode to AVC only
• Conference Line Rate
• Video Quality – Motion or Sharpness
•Video Layout
Video Protocol Support in CP Conferences
The video protocol selected by the system determines the video compression standard used
by the endpoints. In Continuous Presence conferences, the system selects the best video
protocol for each of the endpoint according to the endpoint’s capabilities.
The following Video protocols are supported in CP conferences:
• H.261 - the legacy video compression algorithm mandatory to all endpoints. It is used
by endpoints that do not support other protocols.
