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), 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.
