Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide

Media Relay - SVC Conferencing

SVC Conferencing is based on the SVC video protocol and SAC audio protocol.

SVC Conferencing offers high resolution video conferencing with low end-to-end latency and improved Error Resiliency without video transcoding by the MCU, hence using less video resources.

The Polycom multipoint media server, acts as an integrated media relay engine that provides media streams for displaying conferences at low latency video experience in video conferences. For more details, see "SVC-based Conferencing” on page 2-12.

AVC Conferencing - Video Session Types

All endpoints have AVC capabilities and can connect to AVC conferences running on the MCU. AVC-based Endpoints can connect can connect using different signaling protocols and different video protocols.

Based on the video processing required during the conference, the RMX offers two Video Session Types for AVC-based conferencing:

•Continuous Presence

•Video Switching

The video session type determines the video display options (full screen or split screen with all participants viewed simultaneously) and the method in which the video is processed by the MCU (with or without using the MCU’s video resources).

Continuous Presence (CP) Conferencing

The dynamic Continuous Presence (CP) capability of the RMX system enables viewing flexibility by offering multiple viewing options and window layouts for video conferencing.

Endpoints can connect to the conference using any signaling protocol (H.323, SIP, ISDN/ PSTN and RTV), line rate (up to a maximum line rate defined for the conference), Video Protocol (H.261, H.263, H.264 Base and High Profile) and at any resolution and frame rate (provided they meet the minimum requirements set for the conference).

In Continuous Presence conferences, the MCU receives the video stream from each endpoint at the video rate, video resolution and frame rate that it is capable of sending, and it superimposes all the received streams into one video stream that includes the input from the other endpoints arranges in the selected video layout.

Participants do not see themselves in the video layout. By Default, the speaker is shown in the top left layout cell in symmetric layouts, in the larger cell in asymmetric layouts, or in full screen. The speaker sees the previous speakers (their number depends on the number of cells on the speaker’s layout.

The Continuous Presence video session offers layouts to accommodate different numbers of participants and conference settings including support of the VUI annex to the H.264 protocol for endpoints that transmit wide video instead of 4CIF resolution. Each participant can select his/her layout for viewing during the conference, as can be seen in Figure 2-1.
