Enabling H.264 Cascade and SVC Optimized Content Sharing in AVC CP Conferences
When H.264 Cascade and SVC Optimized is selected as the Content Protocol, an additional
field, Content Resolution is displayed in the Content Video Definition pane.
In SVC Conferencing Mode and CP and SVC Conferencing Mode, the Content Resolution option
is disabled.
The Content Resolution is a fixed resolution and frame rate for Content sharing in a Cascaded
Conference. The Content Resolution that are available for selection are dependent on the Line
Rate and Content Settings that have been selected for the conference.
The following table summarizes the interaction of these parameters.
The selection of the appropriate Content Resolution option, when several options are
available, should be based on the line rate and capabilities that can be used by most or all
endpoints connecting to the conference.
Examples:
• If the conference Line Rate is 1024 kbps.
and
•If the Content Settings selection is Graphics.
—Content Resolutions of HD720/5 and HD1080/15 are selectable with 256 kbps and
768 kbps allocated as the Conference Content Rate respectively.
The higher Content Resolution, HD1080/15 should be selected only if most of the
endpoints connecting to the conference can support a Content Rate of 768Kbps,
which requires the participant to connect to the conference at a Line Rate of
1024kbps.
