<p>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.</p> |
