Fragmented file structure for live media stream delivery

摘要

Media files such as MPEG-4 files are fragmented to allow for media and live media creation and delivery. A MPEG-4 standard description box includes synchronization information, end of file information, and chapter information to provide signaling information for near live playback of fragments. Playback can begin upon receiving a first MPEG-4 file fragment. A second MPEG-4 file fragment can be requested using information included in the first MPEG-4 file fragment.
