The descriptor instantiationTracks is simply intended to indicate the number and type of tracks that are found in a media item, whether it is analog or digital. (e.g. 1 video track, 2 audio tracks, 1 text track, 1 sprite track, etc.) Other configuration information specific to these identified tracks should be described using instantiationChannelConfiguration.

Does this mean how many ‘essence tracks’? in a digital file?
