    摘要: Since there is a case where reproduction of metadata is limited according to the processing power of a reproduction apparatus or the designation from a user, the invention provides a data structure in which metadata whose preferential reproduction is desired can be selected and reproduced. The metadata relevant to a moving image includes a stream data structure including one or more access units each being a data unit which can be independently processed, and each of the access units includes first data to specify an effective period defined with respect to a time axis of the moving image, object area data describing a spatio-temporal region in the moving image, second data including one of or both of data to specify a display method relevant to the spatio-temporal region and data to specify a processing to be performed when the spatio-temporal region is specified, and third data to specify, in a case where one or more access units exist on a same screen in the moving image at a time of reproduction of the metadata, reproduction priority of each of the access units.

    摘要: For a reproduction device in which a usable memory size has an upper limit, this invention discloses a novel structure of metadata, which can suppress the number of seeks of a CD or a DVD occurring at a time of reproduction of metadata of a moving image including a large number of scripts and hyper texts (HTML) each having a small data size, and the number of times of file request transmission/reception through a large number of networks. In the metadata of the moving image, in the case where access units AU#2 and AU#3 require EF#1, and access units AU#2 to AU#4 require EF#2, the EF#1 and the EF#2 are embedded in front of the AU#2, and a script in the AU uses a file name, a file identifier, or a virtual buffer offset in order to specify the EF to which reference is made. Embedding of a file and identification of the file are realized by causing the EF and the AU to have file identification information respectively and by specifying the file identification information from the script.
