Apparatus and method for recording and reproducing data on and from a DVD-Audio disk
First Claim
1. An apparatus for recording and reproducing a data from/to a DVD-Audio disk, comprising:
- a recording portion comprising an encoder to encode data, the data comprising an audio manager (AMG) having information on an audio title (ATS) and the ATS has audio title set information (ATSI) followed by contiguous audio objects (AOBs), the ATSI includes audio stream attributes, each audio stream attribute indicating an audio coding mode, a first, second, or third quantization bit number corresponding to the data to be recorded, a first, second, third, fourth, fifth, or sixth sampling frequency corresponding to the data to be recorded, and decoding algorithm information relating to a number of audio channels of the data to be recorded, and 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, and an optical pickup to record the encoded audio data on the DVD-Audio disk. a reproducing portion comprising a data receiver to receive the audio data retrieved from the DVD-Audio disk, a controller to generate an audio control signal including the audio coding mode, the sampling frequency of the six potential sampling frequencies, the number of audio channels, and the detected one of the first through third quantization bit numbers based upon information on the audio data, an audio decoder to decode the audio data, to multi-channel mix, to sampling-frequency convert, to requantize the decoded audio signal according to the audio control signal, and to generate an output decoded audio data, an audio output circuit to convert the output decoded audio data into an analog audio signal; and

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.
