Abstract: In one example, a device for retrieving multimedia data, the device comprising one or more processors configured to retrieve data of a first segment of a representation of multimedia content in accordance with data of a copy of a manifest file stored by the device, retrieve a portion of a second segment of the representation in accordance with the manifest file, wherein the second segment occurs after the first segment in the representation, and wherein the portion of the second segment indicates that the manifest file is to be updated, update the copy of the manifest file stored by the device based on the indication that the manifest fife is to be updated, and retrieve media data of the second segment in accordance with the updated manifest file.

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.

Abstract: In one example, a device includes one or more processors configured to determine that a manifest file for media content indicates that the media content includes a first period and a second period, that the manifest file indicates that the first and second periods are continuous, and that advertisement media data is available for insertion between the first and second periods, select a first adaptation set in the first period based at least in part on characteristics signaled for the first adaptation set, retrieve media data of the first adaptation set based on the selection of the first adaptation set, retrieve the advertisement media data, and retrieve media data of a second adaptation set in the second period that the manifest file indicates is associated with the first adaptation set based on the selection of the first adaptation set and store the retrieved media data to a memory.

Abstract: A device for receiving streaming data includes a broadcast or multicast middleware unit configured to receive the streaming data via a second service and a proxy unit configured to be disposed between the middleware unit and a client application, the proxy unit further configured to receive an indication of whether the streaming data is to be received via a first service or the second service, when the indication indicates that the streaming data is to be received via the first service: disable the middleware unit; and receive the streaming data via the first service, and when the indication indicates that the streaming data is to be received via the second service: activate the middleware unit to receive the streaming data via the second service, wherein the second service comprises at least one of a broadcast service or a multicast service; and receive the streaming data from the middleware unit.

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.
