Abstract: The present disclose describes techniques for delivery and rendering of streamed media using error tags in a corresponding media playlist. The playlist may represent organization of the media item, providing information of coded media segments that constitute the media item. When segments of coded media are received for a media item, a determination may be made whether the coded media segments contain errors. When a coded media segment is encountered that does not contain an error, a playlist entry representing the coded media segment may be added to the playlist. When a coded media segment contains an error, a playlist entry may be added to represent this coded media segment. This playlist entry may indicate the segment error. The playlist may be stored for access by player device(s).

Abstract: The present disclose describes techniques for delivery and playback of media using identifiers for offline playback, According to these techniques, a segment of media to be played may be identified from a manifest file. It may be determined whether the identical segment is available in local storage. When the identified segment is available in local storage, an identifier of the identified segment contained in the manifest file may be compared to an identifier of the segment in local storage. If the identifiers match, the segment may be played from local storage. Otherwise, the identified segment may be retrieved from a network location.

Abstract: An embodiment of a method of requesting a plurality of media streams can include, as performed by a computing device, receiving a control input to control a playback function of at least one of the plurality of media streams, determining a download bandwidth between the computing device and a media source on a network, classifying the at least one of the plurality of media streams based on the control input and total download bandwidth, and sending a plurality of requests for the plurality media streams over a single connection to the media source, wherein at least one of an order or a content of the requests is based on the classification. The sending of the media stream requests can utilize at least one of a server-side protocol for multiplexing media streams over a single connection or one or more of HTTP pipelining or HTTP range requests over a single connection.

Abstract: This disclosure relates to techniques for a wireless device to detect network bandwidth throttling and dynamically select a buffer threshold. The wireless device may establish a wireless link. Data for a downlink stream may be requested when an amount of buffered data for the stream is below a lower buffer threshold, received via the wireless link, and buffered. Data requests for the stream may be stopped when the amount of buffered data for the stream is above an upper buffer threshold. The upper buffer threshold may be selected based on characteristics of the wireless link and the stream. Throughput of the wireless link may also be monitored during multiple time windows, and the wireless device may determine whether the wireless link caps bandwidth below a bandwidth threshold based on the throughput monitoring.

Abstract: System and methods for storing streamed media data to memory for future playback are provided. A device may stream media data associated with a movie over a network connection. The data streamed to the device will be saved to device memory and will then be playable offline. A manifest associated with the media data will be downloaded to the device and modified to reflect the location of the locally stored media data. During subsequent playback of the media data, the manifest will indicate that at least a portion of the media data exists in local memory. Some portions of the media data not stored locally may be subsequently retrieved from a remote source. The stored data may be updated or added to as necessary.
