  • Method for distributing multiple description streams on servers in fixed and mobile streaming media systems
    Patent number: 6757735
    Abstract: A method and system for streaming media data to a fixed client and/or a mobile client. In one method embodiment, the present invention recites encoding media data to be streamed to a client into a first multiple description bitstream and into a second multiple description bitstream. The present method then determines the appropriate plurality of servers from a network of servers onto which the first and second multiple description bitstreams should be distributed. The present embodiment then recites distributing the first and second multiple description bitstreams to the appropriate plurality of servers positioned at intermediate nodes throughout a network such that a client is provided with access to the media data via a plurality of transmission paths. The present method is also well suited to redistribution of multiple description bitstreams to servers based upon time-varying demand, client movement, and the like.
