DATA PROCESSING DEVICE, DATA PROCESSING METHOD, PROGRAM, PROGRAM RECORDING MEDIUM, DATA RECORDING MEDIUM, AND DATA STRUCTURE

摘要

A data processing device and method for specifying data which is multiplexed into multiplexed data according to metadata irrespective of the number of pieces of data, a program, a program recoding medium, a data recoding medium, and a data structure are disclosed. Clip() which is metadata on a program stream formed by multiplexing elementary streams contains sets of a stream_id defined for each attribute of data in the MPEG-2 system (ISO/IEC 13818-1) and used for identifying data and a private_stream_id for identifying data having an attribute not defined by the MPEG-2 system. The number of sets is equal to the number of elementary streams number_of_streams multiplexed into a program stream. An elementary stream multiplexed into a program stream is specified by the stream_id and the private_stream_id contained in the Clip(). This invention can be applicable to, for example, game machines using a DVD.
