Embodiment Construction

[0055] In the drawings, the same reference numerals denote parts serving the same functions, referring to parts that are not important for describing the concept of the present invention, and their detailed descriptions are omitted for convenience.

[0056] The data structure of DVD Audio is similar to that of DVD Video. Therefore, DVD-Audio includes a data area for recording audio data and an information area for recording information on the audio data. The DVD player may be embodied as a DVD audio player or a DVD audio / video player. Of course, DVD players have a mechanism for determining whether an inserted DVD is DVD-Audio or DVD-Video. DVD-Audio of the present invention has almost the same structure as DVD-Video, and high-quality audio data is obtained with some partially changed data structures.

[0057] The basic file structure recorded in the DVD-Audio information area is shown in FIG. 1 to illustrate the directory structure of DVD-Video and DVD-Audio. The directory ...

Abstract

A DVD-Audio which includes a data zone for storing data to be reproduced and an information zone for storing information on the data to be reproduced. The information zone includes directories of a video title set (VIDEO_TS) and an audio title set (AUDIO_TS). The AUDIO_TS directory includes information on an audio manager (AMG) having information on audio titles. The data zone includes the audio titles each having an audio title set information (ATSI) followed by a plurality of contiguous audio objects (AOBs). The ATSI includes a plurality of audio stream attributes each having an audio coding mode, first to third quantization bit numbers, first to third sampling frequencies and decoding algorithm information relating to the number of audio channels. Each of the AOBs includes a plurality of audio packs recorded with audio data corresponding to the decoding algorithm stored in the audio stream attribute. A recording and / or reproducing apparatus records the data and the information on the data or the DVD-Audio and / or reproduces the data and the information on the data therefrom.

Description

[0001] This application is a divisional application of a patent application with an application date of October 20, 1997, an application number of 97126076.1, and a patent application titled "DVD audio disk, and its playing device and method". technical field [0002] The present invention relates to a digital versatile disc (DVD), and a device and method for playing DVD, and more particularly to an audio DVD (hereinafter referred to as "DVD audio") and a device and method for playing DVD.
