Defining AVC-Based Conference Profiles

New AVC CP Profile - Video Quality Parameters

Field/Option Description

Content Video Definition

Content Settings	Select the transmission mode for the Content channel:
	• Graphics — Basic mode, intended for normal graphics
	• Hi-res Graphics — Higher bit rate intended for high resolution graphic display
	• Live Video — Content channel displays live video
	• Customized Content Rate — 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 Sharing
	Parameters in Content Highest Common (Content Video Switching) Mode.
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.
	For more information, see Enabling AS-SIP Content.
Multiple Content	Click this check box to enable the Multiple Content Resolutions mode, in which
Resolutions	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.
