摘要：Abstract Title: METHOD AND APPARATUS FOR ENCAPSULATING IMAGE DATA IN A FILE FOR PROGRESSIVE RENDERINGA method of encapsulating image data in a media file, the image data being related to a main image to be generated based on a plurality of input images, the method comprising: obtaining the plurality of input images, at least one input image being associated with different versions of the input image; generating descriptive metadata for describing the main image; encapsulating the plurality of input images and the descriptive metadata in the media file; where the method further comprises: generating progressive information (e.g. an indication of a progressive refinement pattern, indicative of a scanning order of input images, e.g. an index in a list of predefined progressive refinement patterns) defining a set of consecutive progressive steps for generating a version of the main image, each progressive step being associated with a set of input image versions required to generate the version of the main image; and embedding the progressive information in the descriptive metadata.
