Abstract: A data processing device and a data processing method, a program and a program recording medium, a data recording medium, and a data structure, all enable data multiplexed into multiplexed data to be specified according to metadata irrespective of the number of pieces of data. A Clip( ) being metadata about a program stream into which a plurality of elementary streams are multiplexed includes as many stream_id/private_stream_id sets as the number of elementary streams number_of_streams. The stream_id/private_stream_id sets each consist of a stream_id, defined for each attribute of data in the MPEG-2 System (ISO/IEC 13818-1), for identifying data, and a private_stream_id for identifying data whose attribute is not defined in the MPEG-2 System. And each of the elementary streams multiplexed into the program stream is specified on the basis of the stream_id and the private_stream_id included in the Clip( ). Embodiments are applicable to, e.g., game machines using a DVD.

Abstract: For a content-prerecorded large capacity disc-shaped recording medium, a user interface having high flexibility is accomplished. Button image data, corresponding sound data as an effect sound, and control commands for the sound data and image data are multiplexed with a stream and recorded on the disc. A scenario reproduced from the disc is stored in a buffer 104. The image data and sound data are stored in a buffer 105. Image data is read from the buffer 105 in accordance with a scenario and expanded to a graphics plane 133. In addition, corresponding sound data is read from the buffer 105 and reproduced by a sound player 106D. When a button image is varied in accordance with a state change of the button, an effect sound is reproduced. As a result, a more effective user interface is accomplished.

Abstract: A reproduction apparatus has a player section, a content reproduction section, an interface section. The player section has a read section reading data from the record medium on which the content data containing at least one of a video data stream and an audio data stream and a reproduction control program controlling the reproduction of the content data are recorded, an input section accepting an input from a user, and an output section outputting the reproduced content data. The content reproduction section reproduces the content data according to the reproduction control program. The interface section interfaces among the content reproduction section, the reproduction control program, and the player section. When a command representing an end of the reproduced content data is described in the reproduction control program, the reproduction control program supplies the command to the interface section and the interface section executes a process corresponding to the command.

Abstract: An information processing apparatus, an information processing method, a program storage medium, and a program for permitting the selection of a recording method maximizes the number of consecutive angle change units with priority given to an AV stream rate. A target AV stream rate is acquired, a jump distance is selected, and a jump time corresponding to the selected distance is acquired. A minimum angle change time is calculated from the jump time and a data read rate. The size of a minimum angle change unit is determined from the minimum angle change time and the AV stream rate. The number of minimum angle change units within the jump distance is calculated. The number of recordable angles is checked. The method is selected whereby the largest number of data items can be recorded consecutively on condition that the necessary number of angles is provided. This invention can be applied to recording/reproducing apparatuses.
