The techniques described herein relate to methods, apparatus, and computer readable media configured to process multimedia data. The multimedia data includes a hierarchical track structure with at least a first track and a second track, such that the first track is at a first level in the hierarchical track structure and the second track is at a second level in the hierarchical track structure above the first level of the first track. First metadata is contained within the first track and second metadata is contained within the second track. The multimedia data can be decoded by performing, based on the first metadata and the second metadata, a track derivation operation on the media data associated with the first track to generate the media data of the second track such that the second track is a derived track of the first track.
