Polycom® RealPresence® SVC-Based Conferencing Solutions Deployment Guide

The following diagram illustrates an SVC-based conference:

For instance, an SVC endpoint might want to receive three video streams at different frame rates and resolutions, and create a conference layout with the received video streams. Each SVC-enabled endpoint sends and receives encoded SVC bit streams to and from the RealPresence Collaboration Server.

For example, the SVC stream sent from a RealPresence Desktop client (1) will transmit bit streams suited for both a RealPresence Mobile client (2) and a RealPresence Desktop client (4). The transmitted bit streams might contain a compressed video with a lower bit rate to support the capability of the receiving client.

The RealPresence Collaboration Server determines which of the incoming bit streams to send to each endpoint. It does not perform any encoding and decoding, or any transcoding of the video streams. The RealPresence Collaboration Server functions as the multipoint media relay to the endpoints. For voice activated selection of the video streams, the RealPresence Collaboration Server determines which of the incoming bit streams to send to each endpoint.

SVC video conferences provides a robust bandwidth-efficient technology that delivers a consistently high-quality user experience across networks with varying degrees of quality of service. SVC increases the scalability of video networks and enables mass desktop video deployments while reducing total networking equipment cost.
