Abstract: A method of transporting media data includes, by a file-based protocol sending unit of a source device, receiving a stream of data comprising Segments of media data from a segmenter of the source device that forms the Segments, each of the Segments comprising a respective individually retrievable file associated with a unique uniform resource locator (URL), determining locations of media delivery events (MDEs) in the stream of media data, wherein the MDEs include data for at least a portion of one of the Segments, determining one or more transmission time requirements for the MDEs representing times at which the MDEs are to be sent to a client device, and providing the MDEs and data representing the transmission time requirements to a physical layer sending unit of the source device according to available delivery slots for the physical layer sending unit.

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 block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server, which might include a cache. A client device can be adapted to take advantage of the ingestion process as well as improvements that make for a better presentation independent of the ingestion process. The client devices and ingestion system can be coordinated to have a predefined mapping and template for making block requests to HTTP file names that a conventional file server can accept through the use of URL construction rules. Segment size might be specified in an approximate manner for more efficient organization.
