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.

Abstract: A system and methods are disclosed for serving combined media using resource metadata referencing original media data. Combined resource metadata is created from combining the metadata of two or more files for a virtual media file representing the requested combined media. The combined data can be adjusted to synch audio and video portions as needed for combining the files. The virtual media file references the original media files and serves the content on-the-fly, rather than creating a new file with the combined media, at a savings of server response time and memory consumption, while maintaining high performance.
