public class TrackReferenceBox
extends Box

8.3.3.1 Definition

• Box Type: `tref’
• Container: TrackBox (�?trak’)
• Mandatory: No
• Quantity: Zero or one

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.

Exactly one Track Reference Box can be contained within the Track Box.

If this box is not present, the track is not referencing any other track in any way. The reference array is sized to fill the reference type box.
