摘要 |
When the same object appearing in a moving picture is divided into a plurali ty of items of data (access units), search results using meta data is easily displayed. A meta data stream includes two or more access units AUs having a n 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 pluralit y of access units AUs is selected (S8200 or S8206), the access units being determined to be the same objects by the object_id and being determined to b e the same scene by the object_subid (S8203), and the selected access unit AU is used to search for an object (S8201). |
