/* 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.
*
* |SegmentBase|
*
* Describes common initialization information for |Segment|s in a
* |Representation|.
*
* 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.
