A meta data stream includes two or more access units AUs having an object_id for specifying whether or not objects designated by object region data in two access units AUs are semantically identical, and an object_subid for specifying whether or not the object region data in the two access units AUs are data on the same scene. From the meta data stream, one of a plurality of access units AUs is selected, the access units being determined to be the same objects by the object_id and being determined to be the same scene by the object_subid, and the selected access unit AU is used to search for an object.
