Conference Profile Parameters - Polycom RealPresence 1800 Administration Manual

Conference Profile Parameters

The following tables list the conference parameters that you can enable on the RealPresence Collaboration
Server.
General Parameters
Field/Option Description
Display Name Provide a meaningful name for the profile.
Line Rate Specifies the maximum bit rate at which endpoints can connect to conferences. The line rate is
the combined video, audio and content rate.
Note: Downspeeding is not supported. As a result, ISDN-video calls will consume bandwidth
resources according to the line rate specified in the conference profile. For example, if the
conference line rate is 512kbps, ISDN-video calls connecting at lower line rates (256kbps) still
consume the bandwidth resources of 512kbps calls. As a result, if bandwidth resources are fully
consumed, ISDN-video calls may be rejected before media card resources are exhausted.
Conferencing Choose one of the following:
Mode
• Continuous Presence (CP) — (also known as AVC) This mode supports the H.264
Advanced Video Coding (AVC) compression standard. In CP mode, the MCU selects the best
video protocol, resolution, and frame rate for each endpoint according to its capabilities.
• SVC Only — This mode supports an extension of the H.264 standard, known as H.264
Scalable Video Coding (SVC). 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 endpoints that support H.264 SVC. Enabling this
setting disables many of the other template settings.
• CP and SVC — (also known as or mixed mode) This mode enables both AVC-only endpoints
and endpoints supporting SVC to join a conference.
Routing Name Assign a routing name or allow the system to assign one automatically.
• If all ASCII text is entered in the Display Name, it is used also as the Routing Name.
• If any combination of Unicode and ASCII text (or full Unicode text) is entered in the Display
Name, the ID (such as Conference ID) is used as the Routing Name.
Video Switching Available only for Appliance Editions.
An alternative to Continuous Presence (CP) mode, this option provides HD video while using
MCU resources more efficiently. All participants see the current speaker full screen while the
current speaker sees the previous speaker.
When enabled:
• The minimum available line rate is 768 kbps
• All endpoints must connect at the same line rate. Those that don't support the specified line
rate are connected in voice-only mode.
• You can also enable H.264 high profile, which allows the conference to use Polycom's
bandwidth-conserving H.264 High Profile codec.
Operator Not available when Video Switching is enabled.
Conference
Enable this option to define the profile of an operator conference.
