Abstract: Methods for delivering application content signaling information may include a generating a metadata fragment for application content items of an application to be acquired by a receiver device, adding to the metadata fragment a first set of attributes indicating that rendering of a linear service or a group of linear services is performed by a media player embedded in the application, and transmitting the metadata fragment to the receiver device. The first set of attributes may include an application launch page or launch file indicator for the application, and/or an indication of required capabilities for rendering the application and associated application content items. The first set of attributes may include a start time and an end time for at least one distribution window for the application, and the at least one distribution window may be associated with information about auxiliary application content delivered during the at least one distribution window.

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 client device includes a memory comprising a buffer for buffering data having real-time constraints and a hardware-based processor comprising digital logic circuitry. The processor is configured to execute a real-time application configured to determine times during which the data will be available for download, determine a time at which the data is needed to prevent a buffer underrun for the buffer, and when the data is available, send a request for the data and deadline information representative of the time at which the data is needed to avoid the buffer underrun. In this manner, a sending device can prioritize delivery of the requested data to prevent the buffer underrun for the client device.
