<p>A method for processing scalable content stored in a first set of data which contains samples for presenting a presentation at a plurality of scales of scalable content, the method comprising:
receiving one of a plurality of extractor track sets with the one of the plurality of extractor track sets including a second set of data derived from the first set, wherein each of the plurality of extractor track sets corresponds to one of a plurality of operating points within the scalable content, the second set containing references to the first set for use in identifying first operating point data for a first operating point from the first set, the first operating point data being a subset of the first set of data; and
accessing, with a digital processing system, the references to transmit, store or present data, referenced by the second set, from the first set without examining each piece of the first set of data and without examining all of the plurality of extractor track sets.</p> |
