摘要： A smooth streaming system provides a stateless protocol between a client and server in which the server embeds incremental control information in media fragments. The server provides uniform media fragment responses to media fragment requests that are cacheable by existing Internet cache infrastructure. The smooth streaming system receives media data in fragments from one or more encoders, creates an index of each fragment, and stores the fragments. The server provides fragments to clients that contain metadata information describing the encodings available on the server and the encoding of the fragment. The server may also provide information within each fragment that allows the client to determine whether the client is requesting data too fast or too slow, so that the client can adapt its request rate to a cadence in tune with the rate at which the server is receiving encoder data.

摘要： An adaptive streaming system is described herein that provides a stateless connection between the client and server for streaming media playback in which the data is formatted in a manner that allows the client to make decisions and react more quickly to changing network conditions. The client requests uniform chunks of media from the server that include a portion of the media. The adaptive streaming system requests portions of a media file or of a live streaming event in small-sized chunks each having a distinguished URL. This allows streaming media data to be cached by existing Internet cache infrastructure. Each chunk contains metadata information that describes the encoding of the chunk and media content for playback by the client. The server may provide chunks in multiple encodings so that the client can switch quickly to chunks of a different bit rate or playback speed.

摘要： A multispeed playback system is described herein that allows for playback of smooth streaming media presentations at speeds other than the normal speed or direction, while still using an underlying platform that does not natively support multispeed. The system provides frames to the underlying platform so that the platform is still playing 1× content while the system manipulates video and/or audio samples being fed to the platform to make rendered data look appropriately for a selected speed and direction. The system may feed the underlying platform frames at a faster rate or skip every other frame for faster playback, or may feed each frame to the underlying platform multiple times for slower playback. Thus, the multispeed playback system allows a client application developer to provide users with expected multispeed playback at the client without encoding multiple different streams at the server.

摘要翻译：这里描述了一种多速播放系统，其允许以不同于正常速度或方向的速度播放流畅的流媒体呈现，同时仍然使用本地支持多速度的底层平台。该系统向底层平台提供帧，使得平台仍然在播放1×内容，同时系统操纵将视频和/或音频样本馈送到平台，以使渲染数据在选定的速度和方向上适当地看起来。系统可以以更快的速度馈送底层平台帧，或者跳过每隔一帧以便更快的播放，或者可以将每个帧多次馈送到底层平台以进行更慢的播放。因此，多速播放系统允许客户端应用程序开发人员在客户端向用户提供预期的多速播放，而无需在服务器上编码多个不同的流。

摘要： A coordinated adaptive streaming system provides a level of intelligence between adaptive streaming heuristics applied to multiple multi-bitrate streams playing on a client computer at the same time. The system receives a media event that includes multiple multi-bitrate streams and plays two or more of the streams. Each stream registers with the coordinated adaptive streaming system so that the system is aware of each of the streams. The system receives a priority indication from each stream that indicates the priority of the stream relative to other streams associated with the media event. The system uses the received priority indications to make adaptive streaming decisions. Thus, the coordinated adaptive streaming system provides playback that more closely aligns with a user's priorities and provides a higher quality experience to a user viewing multiple concurrent media streams.

摘要： Assembling streamed content for on-demand presentation is described. In embodiments, a media asset can be requested from a content distributor, and cacheable segments of the media asset are streamed to the requesting client device. The cacheable segments are received in an initial quality display format for uninterrupted playback of the media asset at the client device while the cacheable segments are being received. An asset matrix that correlates a bit rate and a time position for each cacheable segment in the media asset is also received. The cacheable segments of the media asset can be assembled according to the asset matrix to generate an assembled asset data file of the media asset. The assembled asset data file can then be back-filled with selected ones of the cacheable segments that are replaced with a highest quality display format for on-demand presentation of the media asset when selected for viewing.
