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 Multiple Content Resolutions.
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 Optimized, and the Transcode
to field must be set (checked) to H.264 Cascade.
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.
