SVC-Based Conferencing
In an SVC-based conference, each SVC-enabled endpoint transmits multiple bit streams, called
simulcasting, to the Polycom RealPresence Collaboration Server (RMX). The RealPresence Collaboration
Server sends or relays selected video streams to the endpoints without sending the entire video layout. The
streams are assembled into a layout by the SVC-enabled endpoints according to each of their different
display capabilities and layout configurations.
In a Microsoft Lync 2013-hosted multipoint or point-to-point call, you can view multiple far-end sites in
layouts. RealPresence Group 500 systems display up to five far-end sites on Lync 2013 hosted (SVC),
multipoint calls. RealPresence Group 700 systems display up to six far-end sites.
SVC-based conferencing provides several benefits, including fewer video resource requirements, better
error resiliency, lower latency, and more flexibility with display layouts.
Enabling and Disabling SVC Calls
You can make and receive SVC calls when the Polycom RealPresence Group system is connected to an
SVC-compatible bridge. Enable or disable SVC calls from the Dialing Preferences screen in the web
interface.
For information on enabling encryption for SVC calls, refer to Configuring Encryption Settings for SVC Calls
on page 116.
For more information about the features and limitations of SVC-based conferencing, refer to the Polycom
RealPresence SVC-Based Conferencing Solutions Deployment Guide available at support.polycom.com.
