    摘要： Receiving, transmitting, and generating streamed timed media data organized into temporal media segments, the timed media data belonging to partitioned timed media data comprising timed samples, each timed sample comprising a plurality of subsamples, the timed media data being transmitted as at least two media segment files, each comprising at least one independently encapsulated component. A manifest comprises a dependency item of information indicating a dependency relation between components and a dependency characterization item of information for interpreting the dependency item of information. Alternatively, the manifest comprises at least two different descriptions of at least one component, a first description comprising at least a first dependency item of information indicating a dependency relation from the at least one component to another component and a second description comprising at least a second dependency item of information indicating a dependency relation from another component to the at least one component.

    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： A method of encapsulating an encoded bitstream representing one or more images includes providing description of images and/or sub-image picture, providing composed picture description, and outputting the bitstream. The description of images and/or sub-image pictures identifying portions of the bitstream representing the images and/or sub-images of the one or more images is provided. The composed picture description of at least one composed picture formed by one or more images and/or sub-image pictures also is provided. The bitstream, together with the composed picture description, is output as an encapsulated data file.
