Field Description
Content Settings Select the transmission mode for the Content channel:
• Graphics — basic mode, intended for normal graphics
• Hi-res Graphics (AVC CP Only) — a higher bit rate intended for
high resolution graphic display
• Live Video (AVC CP Only) — Content channel displays live video
• Customized Content Rate (AVC CP Only) - manual definition of
the Conference Content Rate, mainly for cascading conferences.
Selection of a higher bit rate for the Content results in a lower bit rate
for the people channel.
For a detailed description of each of these options, see "Content

AS-SIP Content AS-SIP is an implementation of SIP that utilizes SIP’s built in security
features.
When selected, content is shared using the Multiple Resolutions
mode and is not supported in any other Content sharing mode.
Multiple 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.
When enabled, the H.264 is always selected and can not be
deselected.
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
and you want to define the video settings for content sharing.
Optional. If H.264 Cascade is selected, select the desired Content
Resolution.
For more information, see Chapter 4, “Sharing Content Using
Multiple Content Resolutions Mode” on page 4-19.
