SWITCHED MULTIPOINT CONFERENCE USING LAYERED CODECS

摘要

In one implementation, a conference bridge connects endpoints in a media conference. The various endpoints may have a wide range of video capabilities and audio capabilities. The video conference bridge learns the video capabilities of the endpoints and formulates a media plan based on these capabilities. The media plan instructs the endpoints on the types of media streams to produce. The video conference bridge may shape a media stream received from one of the endpoints by removing one or more layers. Accordingly, each endpoint decodes only the media streams that can be encoded by another endpoint and receives the best possible media stream from each endpoint.
