  • Information recording medium, information reproducing apparatus, information recording method and reproducing method
    Publication number: 20060177199
    Abstract: A design is made for recording and arrangement of application data so as to stably control the behavior of moving picture data based on application data and easily achieve special reproduction of moving picture data. Therefore, moving picture data encoded in a preset format is multiplexed with application data used to control the behavior of a reproduced picture of the moving picture data. Further, the basic process is provided to deal with a first file which contains a multiplexed stream separated by preset units and a second file containing the same data as the application data.

    Publication number: 20060153537
    Abstract: When the same object appearing in a moving picture is divided into a plurality 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 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.
