Abstract
The invention relates according to one of its embodiments to a method for encapsulating a partitioned timed media data, the partitioned timed media data comprising timed samples, at least one timed sample comprising at least one subsample. The method comprising: obtaining at least one subsample from at least one of the timed samples; creating a first track comprising the at least one obtained subsample; obtaining at least another subsample from the same one of the timed samples; creating a second track comprising said at least another obtained subsample; and generating descriptive metadata, the descriptive metadata comprising a unified descriptor comprising: a first parameter which indicates, when set to 1, that the at least one obtained subsample is a complete frame; and at least a second parameter which specifies coding dependencies between the at least one obtained subsample and the at least another obtained subsample.
