Example
The following table 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. uses fixed resolution and frame rate for SVC Only and mixed CP and SVC conferences. 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), along with ISDN endpoints, can be connected as Legacy
Endpoints and receive content through their video channel. This ensures that Content settings are not
changed following the participants connection or disconnection from the conference. If the Send Content
to Legacy Endpoints option is disabled, these endpoints will not receive content.
In SVC Only conferences - Endpoints that do not support the required content parameters (Content line
rate and Content Resolution) cannot share content.
Endpoints that do not support the required content parameters (Content line rate and Content Resolution)
cannot share content.
