/* DASH - Dynamic Adaptive Streaming over HTTP
|
|
*
|
|
* DASH is an adaptive bitrate streaming technology where a multimedia file is
|
|
* partitioned into one or more segments and delivered to a client using HTTP.
|
|
*
|
|
* |Representation|
|
|
*
|
|
* Describes a particular version of a piece of media described in an
|
|
* |AdaptationSet|, a common example being a particular bitrate encoding for an
|
|
* audio or video stream. Direct child of |AdaptationSet|, which contains 1+
|
|
* available |Representation|s of the media.
|
|
*
|
|
* Common class used by all DASH Profiles.
|
|
* Populated by implementation of MPD Parser.
|
|
* Used as data source by implementation of MPD Manager.
|
|
*
|
|
* |MPD|
|
|
* --> |Period|s of time.
|
|
* --> |AdaptationSet|s for each type or group of media content.
|
|
* --> |Representation|s of media, encoded with different bitrates.
|
|
* --> |Segment|s of media, identified by URL (+optional byte
|
|
* range.
