摘要： A method of encapsulation media data in a file, wherein the method comprises: encoding a set of reference images; generating a set of image items to describe the set of reference images; generating an image item describing a derived image corresponding to a panorama based on the set of reference images; generating an association information that associates the image item describing the derived image with the set of image items; generating a parameter data structure containing parameters of the panorama, the parameter data structure being associated with the image item describing the derived image; and embedding the set of image items, the image item describing the derived image, and the association information in the file.

摘要： The present invention concerns a method for generating media files from video sequences, the method comprising by a server:
obtaining from the video sequences, video data composed of a plurality of samples;
generating a video track based on the obtained video data, each video track comprises samples of a video sequence, and the video track is associated with descriptive metadata, the descriptive metadata comprises:
a spatial information related to one or more samples of the associated video track; and
a composition information for organizing generated video tracks to get a full picture when displayed by a client; and
generating media files including the generated video tracks.-

摘要： A method and device for encapsulating media data into a media file and parsing a media file. The method comprising according to one of its aspects: including, in the media file, a first track comprising media samples, each media sample contains a set of one or more NAL units; including, in the media file, a second track comprising an extractor, the extractor is a structure referencing a data entity in a media sample contained in the first track; and including, in the extractor, a copy mode attribute that identifies, in the media sample, the referenced data entity relatively to one or more NAL units contained in the media sample.

摘要： 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.

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.
