Content Sharing Parameters in Content Highest Common (Content Video
Switching) Mode
This section describes the possible content sharing parameters when content Highest
Common mode is used:
• Content Settings
• Content Protocol
• Content Resolution
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” on page 4-9.
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” on page 4-4.
Note: This field is displayed only when H.264 Cascade 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/ISDN
endpoints that do not support H.239 Content (legacy endpoints) over
the video (people) channel. For more information see Chapter 4,
“Sending Content to Legacy Endpoints (AVC Only)” on page 4-21.
