    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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，以从媒体源检索媒体文件，并解码检索到的媒体文件 。 媒体服务进程可以调用用户应用程序来处理自定义URL以便获得由自定义URL引用的对象。
