    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: In one example, a device includes one or more media decoders configured to decode media data, a network interface configured to receive a layered coding transport (LCT) Session Instance Description (LSID), the LSID including information representing a plurality of LCT sessions, each of the LCT sessions including data of a respective one of a plurality of representations of a DASH media presentation and data of one or more of the LCT sessions, and a processor configured to initiate consumption of one or more of the representations of the DASH media presentation using the LSID and without using a manifest file for the DASH media presentation, wherein to initiate consumption, the processor is configured to receive, via the network interface, packets of the LCT sessions including portions of data of the one or more of the representations; and provide data of the packets to the one or more media decoders.

    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.

    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. The system might include controlling the sequence, timing and construction of block requests, time based indexing, variable block sizing, optimal block partitioning, control of random access point placement, including across multiple presentation versions, dynamically updating presentation data, and/or efficiently presenting live content and time shifting.

    IPC: H04L29/06

    Abstract: Techniques are provided for receiving one or more representations of content wirelessly. The method may involve receiving a media presentation description (MPD) that includes parameters for reception of data segments for multiple representations of content via broadcast transmission and unicast transmission (2312). The method may involve determining whether the broadcast transmission or the unicast transmission is appropriate for reception of the data segments (2314) and selecting a given representation from among the multiple representations of the content based on a criteria of the mobile entity (2316). The method may involve receiving the data segments for the given representation based at least in part on the parameters for the determined one of the broadcast transmission and the unicast transmission (2318).
