Abstract: A client device presents streaming media and includes a stream manager, a request accelerator, and a source component coupled to the stream manager and the request accelerator for determining which requests to make. A rate selection process can make rate decisions so that the buffer is filled when it is low, avoiding erratically changing rates and can choose the correct steady rate quickly. Multimedia download strategies can be used for HTTP that allow for accurate rate estimations, achieving link capacity even if network delays and packet loss rates are high, achieving timely delivery of the stream, and achieving relatively steady download rates with little short term variability. A receiver might use multiple HTTP connections, decompose media requests into smaller chunk requests, synchronize the connections using TCP flow control mechanisms, and request data in bursts. In addition, the receiver might use an HTTP pipelining process to keep the connections busy.

Abstract: Embodiments provide methodologies for reliably storing data within a storage system using liquid distributed storage control. Such liquid distributed storage control operates to compress repair bandwidth utilized within a storage system for data repair processing to the point of operating in a liquid regime. Liquid distributed storage control logic of embodiments may employ a lazy repair policy, repair bandwidth control, a large erasure code, and/or a repair queue. Embodiments of liquid distributed storage control logic may additionally or alternatively implement a data organization adapted to allow the repair policy to avoid handling large objects, instead streaming data into the storage nodes at a very fine granularity.

Abstract: Aspects of this disclosure generally relate to a method of retrieving video data of multimedia content. In an example, the method includes determining a first interval between switch points for a first representation of the multimedia content and a second interval between switch points for a second representation of the multimedia content, wherein the first interval is less than the second interval. The method also includes, based on the determination, submitting one or more network requests for an amount of video data from the first representation that has a playback time that is at least equal to a playback time between switch points in the second representation. The method also includes, after submitting the request for the amount of video data from the first representation, retrieving video data from the second representation.
