Abstract
The invention relates to encapsulating scalable tiled timed media data comprising timed samples in a server and providing a timed media data bit-stream from encapsulated scalable tiled timed media in a client device. Each timed sample comprises a first layer and at least one second layer and at least one of the layers comprises a plurality of subsamples represented by one or more coding units. After having obtained at least one subsample from amongst the plurality of subsamples of one of the timed samples, one track comprising the at least one obtained subsample is created. Next, the created track is independently encapsulated in at least one media segment file, said media segment file comprising mapping metadata for providing information about the at least one obtained subsample relative to the one of the timed samples and the layer it belongs to.
