1. A method comprising:
constructing an international organization for standardization base media file format and high efficiency image file format compliant media container file which contains one or more decoding-wise dependent image items;
constructing a descriptive item property within the media container file, wherein the descriptive item property is associated with a respective image item, wherein the descriptive item property comprises a decodability indicator constructed within metadata of the media container file, the decodability indicator providing information as to whether the respective image item is self-decodable without reference to other image items or decodability is dependent upon one or more other image items; and
in an instance in which the decodability indicator of the descriptive item property indicates that the respective image item is dependent upon one or more other image items for decoding, including dependence information within the media container file that identifies the one or more other image items upon which the decodability of the respective image item is dependent;
wherein the decodability indicator providing information as to whether the respective image item is self-decodable without reference to other image items or decodability is dependent upon one or more other image items is configured to be identified with a file parser;
wherein the dependence information that identifies the one or more other image items upon which the decodability of the respective image item is dependent is configured to be identified with the file parser.
