Enabling H.264 Cascade and SVC Optimized Content Sharing in AVC
CP Conferences
When H.264 Cascade and SVC Optimized is selected in AVC CP conference 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.
Content Protocol • H.263 (AVC CP Only)
Content is shared using the H.263 protocol.
Use this option when most of the endpoints support H.263 and some endpoints
support H.264.
• H.263 & H.264 Auto Selection (AVC CP Only)
Content is shared using H.263 if a mix of H.263-supporting and
H.264-supporting endpoints are connected.
Content is shared using H.264 if all connected endpoints have H.264
capability.
• H.264 HD (AVC CP Only, default)
Ensures high quality Content when most endpoints support H.264 and HD
Resolutions.
• H.264 Cascade and SVC Optimized
All Content is shared using the H.264 content protocol and is optimized for use
in SVC only and Cascaded Conferences.
For a detailed description of each of these settings, see Content Protocols.
Content Resolution Select a Content Resolution from the drop-down menu.
The Content Resolutions that are available for selection are dependent on the
content sharing mode (Highest Common Content or Multiple Content Resolutions),
Line Rate and Content Settings that have been selected for the conference.
For a full list of Content Resolutions see Defining Content Sharing Parameters for a
Conference.
Note: This field is displayed only when H.264 Cascade and SVC Optimized is
selected for Multiple Content Resolution or when H.264 Cascade and SVC
Optimized option is selected as the Content Protocol (in the Highest Common
Content Mode) and is enabled for selection in CP conferences (AVC CP Only). This
option is disabled in SVC conferences.
Send Content to Legacy
Endpoints
When enabled (default), Content can be sent to H.323/SIP (Collaboration Server
1500/1800/2000/4000) or ISDN (Collaboration Server 1500/2000/4000 only)
endpoints that do not support H.239 Content (legacy endpoints) over the video
(people) channel. For more information see Sending Content to Legacy Endpoints
