Conference Manager Configuration

Field	Description
Use existing profile	Links this template to the RMX profile selected in the list below.
	For most purposes, we recommend leaving this box unchecked and
	specifying conference properties directly. See Conference Templates.
RMX profile name	Identifies the profile to which this template is linked. The list contains the
	names of all the profiles available on the currently connected MCUs. If a
	profile is only available on some of the connected MCUs, its entry shows how
	many of the MCUs have that profile (for instance, 2 of 3).
	The system will put conferences using this template on the least used MCU
	that has this profile. If there are none, it selects the least-used MCU and either
	uses the Codian-specific settings (if it selected a Cisco Codian MCU) or falls
	back to the default conference template (if it selected a Polycom MCU).
Conference Settings
Conference mode	One of the following:
	• AVC only — Standard video conferencing mode supporting the H.264
	Advanced Video Coding (AVC) compression standard. In an AVC
	conference, the MCU transcodes the video stream to each device in the
	conference to provide an optimal experience, based on its capabilities.
	This is the only mode that supports the use of Polycom MCU profiles,
	third-party and legacy endpoints, and Codian and legacy RMX MCUs.
	• SVC only — video conferencing mode supporting the Annex G extension
	of the H.264 standard, known as H.264 Scalable Video Coding (SVC). An
	SVC video stream consists of a base layer stream that encodes the lowest
	available quality representation plus optional enhancement layer streams
	that each provide an additional quality improvement. The MCU passes the
	video streams from each device to each device.
	The number of enhancement layer streams sent to a device can be
	tailored to fit the bandwidth available and device capabilities.
	SVC conferencing is only possible with Polycom MCUs and endpoints
	that support H.264 SVC. Selecting this setting disables most of the
	other template settings.
	• Mixed AVC and SVC — Enables both AVC-only endpoints and endpoints
	supporting SVC to join the conference. If the selected MCU doesn’t support
	SVC, the conference is started in AVC mode.
	Note: If the MCU supports SVC but not mixed mode (RMX 7.8), the
	conference fails to start.
	See SVC Conferencing Support. See also the documentation for your
	RealPresence Collaboration Server or RMX MCU.
Conference mode	For mixed conference mode, specifies the video experience optimization
experience	strategy the MCU should implement. The experience optimization strategy
	determines the quality of the video streams that SVC participants receive from
	AVC participants.
	See the documentation for your RealPresence Collaboration Server or RMX
	MCU for detailed data regarding the resolutions each experience setting
	supports for various ranges of line rate.
	Note: All AVC callers must be capable of sending at a line rate available for
	the experience setting. SVC participants receive the same stream quality from
	all AVC endpoints, regardless of their individual capabilities.
