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.
摘要翻译：方法和装置使用诸如HTTP兼容协议之类的传输协议来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，一种方法可以自适应地确定同时接收的两个流之间的时间重叠的最小重叠，以便确定何时在两个流之间切换，并且可以基于连接速度来确定最小重叠。在另一个实施例中，可以将最小播放列表持续时间设置为指定在播放列表中指定的媒体文件的最大持续时间的目标持续时间的倍数。在另一个实施例中，一种方法可以强制在客户端设备处回放的起始点。

摘要： Methods and apparatuses for real-time or near real-time streaming of content using transfer protocols such as an HTTP compliant protocol. In one embodiment, a method includes dividing a stream of data, representing the contiguous time based content of a program (e.g. a live video broadcast), into a plurality of distinct media files, and generating a playlist file having a plurality of tags and Universal Resource Indicators (URIs) indicating an order of presentation of the plurality of distinct media files. The plurality of media files and the playlist file can be made available for transmission to a client device which can retrieve the media files using the playlist file.

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 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 are available, to retrieve the media files from the media source, and to decode the media files retrieved. The media serving process can call the user application to process a custom URL in order to obtain an object referred to by the custom URL.

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 multiple redundant locations that provide media content to client devices using alternative streams. To implement failover protection, a first server device or first content distribution service creates a stream, or multiple alternate bandwidth streams and generates playlist file(s). A second server device or second content distribution service creates a parallel stream, or set of streams. A client attempts to download the playlist file(s) from a first uniform resource locator (URL) using a first stream associated with the first server device or the first content distribution service. If a client is unable to download the playlist file(s) from the first URL, the client attempts to switch to an alternate stream associated with another URL.

摘要： A Quality of Experience (QoE) framework provides a technique to assess the end user experience in a mobile wireless communication environment, such as 2.5G or 3G networks, or in any other wireless or hardwired communication environment. The framework is usable in conjunction with media streaming applications and enables a combination of network layer, transport layer, codec layer, and application layer measurements in extracting results. The extracted results can be used to monitor and improve, if necessary, the end user experience over severely variable network conditions.
摘要翻译：体验质量（QoE）框架提供了一种评估移动无线通信环境（如2.5G或3G网络）或任何其他无线或有线通信环境中终端用户体验的技术。该框架可与媒体流应用程序结合使用，并在提取结果中实现网络层，传输层，编解码层和应用层测量的组合。提取的结果可用于监视和改进，如有必要，最终用户体验在严重变化的网络条件下。
