Example
Table4 -7 summarizes an example of two participants trying to connect to a conference
running at a Line Rate of 1024Kbps. The Content Setting for the conference is Hi Resolution
Graphics and the H264_HD_HIGHRES_MIN_CONTENT_RATE System Flag setting are
used to determine if Content will be shared with the participant.
H.264 Cascade and SVC Optimized
The H.264 Cascade and SVC Optimized option maintains content quality and minimizes
the amount of content refreshes that occur in large cascading conferences when participants
connect or disconnect from the conference.
In AVC CP conferences, each content Line Rate and Content Setting has its own resolution
and frame rate.
In AVC CP conferences, endpoints that do not support the required content parameters
(Content line rate, H.264 protocol and Content Resolution), will not receive content.
Endpoints that do not support the required content parameters (Content line rate and
Content Resolution) cannot share content.
Guidelines
• In Cascading conferences, the cascade link must be H.323.
•H.264 High Profile is not supported.
