摘要:
Described herein is technology for, among other things, performing playback in resource-limited environments. The technology involves identifying one or more primary streams and one or more secondary streams of a piece of media content based on the media content itself and/or on the particular playback scenario and then modifying playback and streaming parameters accordingly. The one or more primary streams may then be given priority in order to ensure a satisfactory playback experience. The playback characteristics, the one or more primary streams of the media content, and the resources available in the playback environment can be monitored and changed throughout playback. Both the device streaming and the device receiving the content may communicate to further optimize playback.

Adjusting media streaming parameters of a media streaming device and media playback parameters of a media playback device is disclosed. In one embodiment, the system probes a network infrastructure to determine a network type, a playback device type, a streaming device type, a media content type, a preroll duration, and a playback device buffer size. Based upon these streaming and playback conditions, values of streaming parameters of a streaming device and values of playback parameters of a playback device are determined. Streaming parameters include the aggressiveness of the network transmitter, the slope of the transmit rate ramp-up, and the maximum transmit rate. Playback parameters include the amount of data prerolled by the playback device. The aforementioned values are sent to streaming and playback device control systems to control the streaming and the playback of the media, during and/or before playback.

Described herein is technology for, among other things, improving playback of media streams by maximizing bandwidth utilization. The technology may be implemented via a remote playback device on a network. It involves monitoring requests for portions of streaming media content and the associated responses to the requests and then adjusting request parameters to more effectively utilize available bandwidth. The effective available bandwidth may be controlled by moderating requests in order to induce behavior favorable to media streaming in the flow control mechanisms which control the amount of data sent in response to a request.

Described herein is technology for, among other uses, performing playback of dynamic content using protocols designed for playback of fixed-length files. The technology involves strategically updating the duration of the content during playback under various conditions. During playback, as the playback position approaches the duration, the duration is refreshed. Also, during playback the rate at which the duration is increasing is used to predict the duration and thus smoothly report the duration to the user. Upon receiving a seek request, if the request is beyond the current duration, the duration will be refreshed to avoid unnecessarily limiting the seek request.

Partial content syncing in a network media receiver is disclosed. One embodiment comprises identifying available cache space on the media receiver, detecting a media data file to be downloaded from a media server, and pre-buffering a portion of the media data on the media receiver prior to selection of the media data file for playback. In this manner, substantially glitch-free playback of a media data file may be started with little delay and with relatively little local storage.

An intelligent retransmission of data stream segments is disclosed. One embodiment comprises detecting a missing media data segment at a media receiver, assigning a value to the missing media data segment based upon media playback consequences of not utilizing the missing media data segment, comparing the value with a threshold, and requesting retransmission of the missing media data segment from a media server if the value meets a predetermined condition relative to the threshold. In this manner, retransmission is requested when it is determined that retransmission will improve playback performance relative to non-retransmission.
