When the reference is to Segment Index Box, this field carries the sum of the subsegment_duration fields in that box; when the reference is to a subsegment, this field carries the difference between the earliest presentation time of any sample of the reference track in the next subsegment (or the first subsegment of the next segment, if this is the last subsegment of the segment or the end composition time of the reference track if this is the last subsegment of the representation) and the earliest presentation time of any sample of the reference track in the referenced subsegment; the duration is expressed in the timescale value in this box.
