Abstract

A media stream delivery system encodes and fragments media streams into numerous media stream fragments maintained on fragment servers. Playlist information, media data, and bandwidth adaption data is provided as box information with media stream fragments to reduce the number of client requests required to begin playback or perform a channel change. A client no longer needs to make separate requests for bandwidth adaptation data, media data, or playlist information. Playback can begin as soon as sufficient media stream fragments are received.
