Video Layout In Cascading Conferences (Cp And Mixed Cp And Svc) - Polycom RealPresence 800s Administrator's Manual

Cascading Conferences
Cascading information applies to AVC Conferencing Mode (CP and mixed CP and SVC) only.
Cascading is not supported with SVC Conferencing Mode.
Cascading enables administrators to connect one conference directly to one or several conferences,
depending on the topology, creating one large conference. The conferences can run on the same MCU or
different MCUs.
There are many reasons for cascading conferences, the most common are:
● Connecting two conferences on different MCUs at different sites.
● Utilizing the connection abilities of different MCUs, for example, different communication protocols.
The following cascading topologies are available for cascading:
● Basic Cascading - only two conferences are connected (usually running on two different
Collaboration Servers). The cascaded MCUs reside on the same network.
● Star Cascading - one or several conferences are connected to one master conference. Conferences
are usually running on separate MCUs. The cascaded MCUs reside on the same network.
System configuration and feature availability change according to the selected cascading topology.

Video Layout in Cascading conferences (CP and mixed CP and SVC)

Cascade links are treated as endpoints in CP conferences and are allocated resources according to
Resolution Configuration for CP Conferences
resolution.
When cascading two conferences, the video layout displayed in the cascaded conference is determined by
the selected layout in each of the two conferences. Each of the two conferences will inherit the video layout
of the other conference in one of their windows.
In order to avoid cluttering in the cascaded window, it is advised to select appropriate video layouts in each
conference before cascading them.
