摘要： The invention relates to a method for obtaining media data and metadata from an encapsulated bit-stream resulting from the encapsulation of one or more bit-streams, the media data of each of the one or more bit-streams being organized into one or more layers, each layer comprising timed samples or sub-samples. A data structure is obtained for referencing metadata including at least one definition of at least one group of timed samples of the media data. At least one operating point descriptor is obtained for each of the one or more bit-streams, the at least one operating point descriptor providing metadata related to descriptive information enabling timed samples belonging to a group of timed samples defined in metadata referenced by the data structure to be independently decoded. Each operating point descriptor associated with one group of timed samples defines the descriptive information of the timed samples belonging to the group.

摘要： The invention relates to encapsulating partitioned timed media data to be streamed to a client's device, the partitioned timed media data comprising timed samples, each comprising a plurality of subsamples. After having grouped several of the subsamples to form at least one group so that at least part of the subsamples belongs to a group of subsamples, at least two subsamples of the same group are selected from amongst the plurality of subsamples of one of the timed samples and at least one track comprising the selected subsamples is created. Next, for the at least one created track, one sub-track box is created for each of the subsamples selected to create the at least one track, at least one of the created sub-track boxes comprising definitions and properties that are common to the selected sub-samples. Each of the created tracks is independently encapsulated in at least one media file.
