摘要

Digital Versatile Discs (DVD) contain high quality audio while maintaining compatibility with the DVD-Video format. This DVD includes, among a plurality of audio streams corresponding to a title, a particular audio stream storing basic audio data according to the Digital Versatile Disc (DVD) -Video format and at least one of the remaining audio streams corresponds to the basic audio data. Extended audio data is stored, and additional data for identifying the extended audio data is stored in an audio stream attribute of the video title set. The apparatus for reproducing the DVD performs a parsing on the reading unit for reading the data recorded from the DVD, the data read by the reading unit, and outputs the resultant basic and extended audio streams. And an audio decoding unit for receiving and processing the basic audio stream and the extended audio stream from the sentence analysis unit, and outputting an audio signal of a form in which the audio quality provided by the basic audio data is enhanced by the extended audio data. . Therefore, the present invention can provide an improved audio quality compared to the audio quality by the DVD-Video format.
