Method and apparatus for re-constructing media from a media representation

摘要

The present invention relates to a new type of random access point adapted to be included in a media representation comprising a plurality of data objects. The random access point is characterized by a reference to a data element in another data object of said plurality of data objects, 5 wherein said referenced data element at least partly describes how to reconstruct media from said media representation. The invention further relates to a method and apparatus of reconstructing media from a media representation. The method comprises receiving a data object comprising at least one reference to a data element in another data object of the media representation; and re- constructing the media by use of information associated with said referenced data element(s).
