DynamicStreamingResource encapsulates multiple representations of a piece of media, such that the player application can dynamically switch from one representation to another. Typically (though not always), each representation is encoded at a different bitrate, and the player application switches between representations based on changes to the client's available bandwidth.

This class provides an object representation of a dynamic streaming resource without any knowledge or assumption of any file format, such as SMIL, Media RSS, F4M, etc.
