METHOD, DEVICE, AND COMPUTER PROGRAM FOR ENCAPSULATING SCALABLE PARTITIONED TIMED MEDIA DATA

摘要

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.

1. A method for encapsulating partitioned timed media data in a server, the partitioned timed media data comprising timed samples, each timed sample comprising a first layer and at least one second layer where at least one of the layers comprises a plurality of subsamples represented by one or more coding units, the method comprising:
obtaining at least one subsample from amongst the plurality of subsamples of one of the timed samples, the obtained subsamples forming a subset of the set of the subsamples of the one of the timed samples; creating one track comprising the at least one obtained subsample; and independently encapsulating the created track in at least one media segment file, said media segment file comprising mapping metadata for providing information about the at least one obtained subsample, the mapping metadata being relative to the one of the timed samples and the layer it belongs to.
