Svc-Based Conferencing - Polycom RealPresence 800s Administrator's Manual

RealPresence Collaboration Server (RMX) 800s/Virtual Edition Administrator's Guide
● Presentation Mode (CP Conferences only) – When the current speaker's speech exceeds a
predefined time (30 seconds), the conference layout automatically changes to full screen, displaying
the current speaker as the conference lecturer on all the participants' endpoints. During this time the
speaker's endpoint displays the previous conference layout. When another participant starts talking,
the Presentation Mode is cancelled and the conference returns to its predefined video layout.
Presentation mode is available with Auto Layout and Same Layout.
 If the speaker in a video conference is an Audio Only participant, the Presentation Mode is
disabled for that participant.
 Video forcing works in the same way as in Lecture Mode when Presentation Mode is activated,
that is, forcing is only enabled at the conference level, and it only applies to the video layout
viewed by the lecturer.
● Telepresence Mode (CP Conferences only) - enables the connection of numerous high definition
telepresence rooms and of different models (such as TPX and RPX) into one conference maintaining
the telepresence experience. This mode is enabled by a special license.
● TIP Support (CP Conferences only) - TIP is a proprietary protocol created by Cisco for deployment
in Cisco TelePresence systems (CTS). Polycom's solution is to allow the Collaboration Server to
natively inter-operate with Cisco TelePresence Systems, ensuring optimum quality multi-screen,
multipoint calls.

SVC-based Conferencing

The SVC-Based conferencing mode provides video without transcoding by the MCU, hence requiring less
video resources while providing better error resiliency and lower latency.
Using the SVC video protocol, SVC conferences provide video bit streams at different resolutions, frame
rates and line rates to SVC-enabled endpoints with various display capabilities and layout configurations.
In the SVC-based conference, each SVC-enabled endpoint transmits multiple bit streams, called
simulcasting, to the Polycom® RealPresence® Collaboration Server. Simulcasting enables each endpoint
to transmit at different resolutions and frame rates such as 720p at 30fps, 15fps, and 7.5fps, 360p at 15fps
and 7.5fps, and 180p at 7.5fps.
The Polycom SVC-enabled endpoints (such as Polycom® RealPresence® Desktop and Polycom®
RealPresence® Mobile) compose the layout according to their layout settings and video capabilities. This
enables the MCU to send or relay the selected video streams to each endpoint without processing the video
streams and sending the composite video layout to the endpoints.
