Abstract: Data objects are delivered over a packet switched network and receivers receive encoded symbols such as repair symbols broadcast or multicast with sufficient information to form requests for additional symbols as needed based on what source symbols or sub symbols are needed or missing. The requests can be made in a unicast or request fashion. Requesting and broadcasting might be done by different entities. A broadcast server can generate and store repair symbols while a source server can store content in source form. A request can be a unicast HTTP byte range request such as a URL starting position and length. Requests might be aligned with starting positions of files. A receiver can calculate starting and ending byte positions of symbols or sub symbols in a file and get indications that conventional HTTP servers are usable for file repair. Repair servers can request broadcast of repair data when byte range requests from multiple receivers overlap.

Abstract: A block-request streaming system provides for low-latency streaming of a media presentation. A plurality of media segments are generated according to an encoding protocol. Each media segment includes a random access point. A plurality of media fragments are encoded according to the same protocol. The media segments are aggregated from a plurality of media fragments.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus establishes a file delivery session (910) with a server in a broadcast network for system information. The apparatus also receives a plurality of metadata fragments (912a-912d, 914a-914d) in the file delivery session. The plurality of metadata fragments including at least one initialization segment description fragment (912d, 914d), wherein the at least one initialization segment description fragment is associated with at least one media segment (942a-942g, 962a-962g) transmitted in another file delivery session (940, 960).
