All Implemented Interfaces:
Box, ParsableBox
public class TrackReferenceTypeBox extends AbstractBox
This box provides a reference from the containing track to another track in the presentation. These references are typed. A 'hint' reference links from the containing hint track to the media data that it hints. A content description reference 'cdsc' links a descriptive or metadata track to the content which it describes. The 'hind' dependency indicates that the referenced track(s)may contain media data required for decoding of the track containing the track reference. The referenced tracks shall be hint tracks. The 'hind' dependency can, for example, be used for indicating the dependencies between hint tracks documenting layered IP multicast over RTP. Exactly one Track Reference Box can be contained within the Track Box. If this box is not present, the track is not referencing anyother track in any way. The reference array is sized to fill the reference type box.
