摘要： Methods and apparatuses provide real-time or near real-time streaming of content using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method includes providing a request for a playlist file (e.g. an updated playlist) and specifying a compression protocol with or for the request; the request can come from a client device which is requesting the playlist from a web server. The web server can provide the playlist in a compressed format.

摘要： Methods and apparatuses provide real-time or near real-time streaming of content, specified in one or more playlists, using transfer protocols such as on HTTP compliant protocol. In one embodiment, a method can execute a user application on a client device to present media files and to control presentation of the media files. The method can further run a media serving process on the client device to retrieve a playlist specifying the media files and a media source at which the media files arc available, to retrieve the media files from the media source, and to decode the media files retrieved. While the media serving process is separate from the user application, they may share the same privileges with respect to memory control, memory space, memory allocation, file system control, and network control.
摘要翻译：方法和设备使用诸如HTTP兼容协议之类的传输协议提供在一个或多个播放列表中指定的内容的实时或接近实时的流传输。在一个实施例中，一种方法可以在客户端设备上执行用户应用以呈现媒体文件并且控制媒体文件的呈现。该方法可以进一步在客户端设备上运行媒体服务进程，以检索指定媒体文件的播放列表和媒体文件可用的媒体源，从媒体源检索媒体文件，并解码检索到的媒体文件。当媒体服务过程与用户应用程序分开时，它们可以共享与存储器控制，存储器空间，存储器分配，文件系统控制和网络控制相同的特权。

摘要： Methods and apparatuses provide real-time or near real-time streaming of content, specified in one or more playlists, using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method can adaptively determine a minimum overlap for an overlap in time between two streams being received concurrently in order to determine when to switch between the two streams, and the minimum overlap can be determined based on connection speed. In another embodiment, a minimum playlist duration can be set as a multiple of a target duration which specifies a maximum duration of a media file specified in a playlist. In another embodiment, a method can enforce a start point for playback at a client device.

摘要： This invention is directed to a system by which data received by an electronic device from a server may be selectively stored in cache. The electronic device may define an anchor that is related to the current position of a playhead reading data stored in cache. The electronic device may then dynamically assign values to each data block of the received file based on the position of the anchor. As the anchor moves the value of data blocks changes, and new incoming data may replace less valuable data previously stored in cache.

摘要： A near real time content streaming system can use a playlist file, in one embodiment, that includes an indicator of the type of content represented by the playlist file. The type can be indicated by a parameter, such as Video on Demand (VOD) or live, or event, that specifies the type of playlist file, and a client device can process the playlist file based upon the type of playlist file indicated by the parameter. For example, the client device, after determining the type of playlist from a playlist file can make efficiency optimizations when processing the playlist file. For example, the client, knowing the playlist file is a VOD playlist, can save the previously used variant playlist when switching to a new variant playlist rather than discarding the previously used variant playlist.

摘要： A content streaming system, such as an HTTP streaming system, can use a variant audio playlist that identifies different audio playlists, such as one playlist in English and one playlist in Spanish, for the same program such as a video program which is specified by a video playlist which can be separate from the variant audio playlist. A client can use the variant audio playlist to select a particular audio content for the same program, and the particular audio content can be referred to by one URL in the variant audio playlist, among a set of alternative URLs, in the variant audio playlist, for alternative audio content.

摘要： Some embodiments provide a method for estimating bandwidth estimate based on a set of statistical measurements that quantifies bandwidth variation. The method receives a piece of media content at a receiving device and computes several instantaneous bandwidth measurements based on sample data blocks or media content received at the receiving device. The method computes the set of statistical measures that quantifies variation between the computed instantaneous bandwidth measurements. Based on the set of statistical measures, the method computes a revised bandwidth estimate for receiving media content at the receiving device. In some embodiments, the method uses the revised bandwidth estimate to determine an amount of media content data to buffer in order to provide an uninterrupted playback.
