Multiple Content
Resolutions
Click this check box to enable the Multiple Content Resolutions mode, in which
content is shared in multiple streams, one for each video protocol: H.263 and
H.264. This allows endpoints with different protocols to connect and disconnect
without having to restart Content sharing in the middle of a conference. For more
information, see Sharing Content Using Multiple Content Resolutions Mode.
When enabled, the H.264 is always selected and can not be deselected.
Note: If Multiple Content Resolutions is selected in a Cascading environment, the
Content Protocol must be set to H.264 Cascade and SVC Optimized and H.264
Cascade must be checked as the Transcode to: setting.
Optional. Select additional protocols:
•H.263 - if the conference will include H.263-capable endpoints that do not support
H.264 protocol for content sharing.
• H.264 Cascade - if the conference will include cascading links that should use a
fixed video format for content sharing.
Optional. If H.264 Cascade is selected, select the desired Content Resolution.
Content Protocol Select the Content Protocol to be used for content sharing in Highest Common
Content Sharing Mode.
•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)
When selected, content is shared using H.263 if a mix of H.263-supporting and
H.264-supporting endpoints are connected, or H.264 if all connected endpoints
have H.264 capability.
• H.264 Cascade and SVC Optimized
All Content is shared using the H.264 content protocol and is optimized for use
in cascaded conferences.
• H.264 HD (AVC CP only, default)
Ensures high quality Content when most endpoints support H.264 and HD
resolutions.
Note: When Multiple Content Resolutions is selected, the Content Protocol field
is hidden.

Parameters for a Conference.
H.264 High Profile

the Content Protocol drop-down menu if all the following conditions are met:
•The selected Conferencing Mode is AVC-CP.
•Multiple Resolutions (Content Transcoding) is not selected.
•The selected Content Protocol is Cascade and SVC Optimized.
If H.264 HD, H.264 Cascade and SVC Optimized is selected, the Content
