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: Systems, methods, and devices of the various embodiments enable HTTP servers, such as HTTP servers providing segments to DASH clients according to the various embodiments, to pass incomplete versions of segments in response to segment requests from the DASH clients. The various embodiments may enable clients, such as DASH clients, to parse incomplete versions of segments.

Abstract: Systems, methods, and devices of the various embodiments enable managing a start time of media content in a media receiver device. A processor of the receiver device may receive media content labeled with a transmission time from a sending device. The processor may determine a service construction delay of the media content of the media content. The processor may determine a time offset of the media content based on the service construction delay. The processor may deliver the media content to a streaming media client in the receiver device using the time offset.

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. A client device can be adapted to take advantage of the ingestion process as well as including improvements that make for a better presentation independent of the ingestion process. The files or data elements are organized as blocks that are transmitted and decoded as a unit, and the system is configured to provide and consume scalable blocks such that the quality of the presentation increases as more of the block is downloaded. Encoding and decoding blocks with multiple independent scalability layers can be done as well.

Abstract: In one example, a device for retrieving multimedia data, the device comprising one or more processors configured to analyze information of a manifest file for multimedia content, wherein the information of the manifest file indicates that at least one representation of the multimedia content includes a temporal sub-sequence, determine one or more locations of data for the temporal sub-sequence, and submit one or more requests for the data for the temporal sub-sequence.

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.
