Abstract
A method for a cache for providing streaming media data to a client system includes receiving a request from a client system for a media meta file, the media meta file comprising a unicast URL for a stream of media data, retrieving the media meta file, initiating a connection with a media server associated with the unicast URL, selecting a multicast channel for broadcast of the stream of media data, modifying the media meta file to include data associated with the multicast channel to form a modified media meta file, sending the modified media meta file to the client system, receiving the stream of media data from the media server, and providing the stream of media data on the multicast channel. The client system receives the stream of media data on the multicast channel.
