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

RealPresence Collaboration Server (RMX) 800s/Virtual Edition Administrator's Guide
Advantages of SVC Conferencing
SVC increases the scalability of video networks and enables mass desktop video deployments. Some of
the advantages of SVC conferencing are:
● Offers high-resolution video conferencing with low end-to-end latency, improved error resiliency and
higher system capacities.
● Allows the SVC-enabled video endpoints to manage display layouts, supporting multiple line rates,
resolutions and frame rates.
● The RealPresence Collaboration Server functions as a media relay server providing low cost
production benefits. The RealPresence Collaboration Server reduces bandwidth usage by only
selecting the necessary video stream to be sent to the endpoints.

SVC Conferencing Guidelines

You can run SVC-based conferences when following the guidelines listed below.
● SVC conferences are supported only with the following:
 SVC Licensing
 SIP over UDP signaling
 SIP over TLS Signaling
 Polycom SVC-enabled endpoints (Polycom® RealPresence® Desktop, Polycom®
RealPresence® Mobile)
 Ad Hoc conferencing via Meeting Rooms and ongoing conferences
● SVC Only conferences can run on the same MCU as AVC Only conferences.
● End-to-end latency on a local network (same site), is around 200mSec to ensure AV sync (also known
as Lip-sync).
● Dial-out is not available in SVC Only conference.
● Dial-in is available as follows:
 AVC endpoints (participants) can only connect to an AVC conference or Mixed CP and SVC
conference. When dialing into SVC Only conferences they will be disconnected and the calls fail.
 SVC endpoints support both AVC and SVC video protocols.
When dialing into SVC Only conferences, they connect as SVC endpoints.
When dialing into AVC Only conferences, they connect as AVC endpoints. They cannot connect
to an AVC conference using the SVC capabilities.
● SVC endpoints can connect to conferences via Entry Queues, however:
 The Entry Queue and Conference Modes must match - both SVC Only or both Mixed.
 Both the Entry Queue and the Conference must have the same line rate.
● SVC endpoints cannot be moved between conferences.
● Content is supported in H.264 (AVC).
 Only the H.264 Cascade and SVC Optimized option is supported.
 LPR and DBA are not supported for SVC content sharing.
● In SVC Only conferences and Mixed CP and SVC conferences, Auto Layout is the default and the
layout display for SVC endpoints is controlled from the endpoint application.
● Site names display on SVC endpoints is controlled from the SVC endpoints.
