Abstract

Techniques are provided for a source computer to generate an encoded video stream having layered sub-streams with differing bitrates while allowing a streaming server to intelligently distribute the appropriate sub-streams to recipients based on their available bandwidth. This may be accomplished by having the source computer generate and send metadata along with the encoded stream to allow the streaming server to detect which data packets belong to each sub-stream. The streaming server is then able to selectively send consistent video sub-streams at appropriate bitrates to each recipient.
