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, 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).
