/* 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.
