Chapter 2-SVC Conferencing Solution Overview

The following diagram illustrates an example of the various devices and bandwidths that can be used in an SVC-based video conferencing environment:

Using the SVC-Based Conferencing Solution

The Polycom RealPresence SVC-Based Conferencing Solution is a powerful and innovative video conferencing mode that, in some cases, provides high-quality video streaming between endpoints with lower resolutions, frame rates, and line rates. SVC conferences also provide higher video capacity, 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 resolution and temporal layers, to the Polycom® RealPresence® Collaboration Server (RMX) or the Polycom® RealPresence® Collaboration Server 800s, enabling 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.

Polycom SVC-enabled endpoints (Polycom® RealPresence® Desktop and Polycom® RealPresence® Mobile) enable video conference layouts to be automatically assembled by the endpoint giving more flexibility to the endpoint. This enables the RealPresence Collaboration Server to send or relay the selected video streams to the endpoints without sending the entire video layout to the endpoints.

The video streams displayed in the conference layout on each endpoint is obtained from the different streams received from each of the endpoints displayed in the layout. Depending on the size of the video cell in the configured layout, the endpoint requests the video stream in the required resolution from the RealPresence Collaboration Server. The higher the display quality and size, the higher the requested resolution will be sent to the endpoint. The endpoint creates the displayed layout from the different video streams it receives.
