Conference Manager Configuration
Polycom, Inc. 205
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
experience
For mixed conference mode, specifies the video experience optimization
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.
Cascade for bandwidth Enables conferences using this template to span Polycom MCUs to conserve
network bandwidth.
Cascading for bandwidth requires site topology information, which the
Polycom RealPresence DMA system can get from a Polycom RealPresence
Resource Manager system (see RealPresence Resource Manager
Integration) or you can create (see Site Topology).
This option and Cascade for size are mutually exclusive. See About
Cascading for more information about enabling cascading of conferences.
