Abstract
The invention relates to a method for encapsulating multi-layer partitioned timed media data in a server, the multi-layer partitioned timed media data comprising timed samples, each timed sample being encoded into a first layer and at least one second layer, at least one timed sample comprising at least one subsample, each subsample being encoded into the first layer or the at least one second layer. The method comprises: obtaining at least one subsample from at least one of the timed samples; creating a track comprising the at least one obtained subsample; and generating a descriptive metadata associated with the created track, the descriptive metadata being organized into one main descriptive box per track, the descriptive information about the organization of the different layers being included into one or more sub-boxes, wherein at most one main descriptive box comprises the one or more sub-boxes.
