Description of the invention (1) The local party of 励 is about a digital multi-function disk (DVD), and a device called Α Ϊ, and the more special is the DVD related to audio (hereafter DVD-Audio) And its playback method and device. "Recently, a so-called video DVD (hereinafter referred to as home video) has been developed which has a higher storage capacity than laser discs (LD) There is a very obvious change in the quality of sound and video. The DVD is only used to store and retrieve audio data. This kind of DVD is called '', -audio. The DVD-Audio provides a large amount of storage and retrieval resources, so the quality is significantly improved compared to the compact disc (CD) or digital audio tape (DAT). The audio signals stored in the CDs of the second, second, and second systems are linear pulse code modulation (pCM) audio. The material is quantized to 16 bits by using a sampling frequency of 44.1 KHz. Digital data stored in is converted to analog signals by CD playback equipment. This ⑶ is much more convenient to use than the previous micro-slot gramophone record (LP), but it is generally considered to be worse than the analog LP in terms of sound quality. This is because the audio signal has a sampling frequency of 44 lKHz and is quantized into 16 bits and stored in the CD. And the audible frequency range may exceed 20KHz, and the dynamic range must be over 120dB. In addition, CDs can only store audio signals of up to two channels, so audio data about multi-channel music cannot be stored and copied. Under these circumstances, various methods have been proposed to increase the number of sampling frequencies and audio channels to improve the sound quality of the CD. ’DVD provides a high-density way to record video and audio. In this regard, the video data is recorded in MPEG (Moving Pictures Expert Group), while the audio data is recorded in linear PCM format.

Description of the invention (2) and so on. Therefore, DVD-Video playback devices are designed to be copied to DVD_Video Audio and Video. This kind of DVD-video production is made for the purpose of storing video data. It is very uneconomical from the viewpoint of storage space if it is only used to store audio data. The data recorded in a DVD-video is higher quality than that in a CD because the audio data of a DVD has a higher sampling frequency and a larger number of quantization bits and channels than a CD. That is, a DVD player can reproduce face-quality audio materials within multiple channels. The DVD's ability to convert data may be up to 10 · 8Mbps. This makes it possible to reproduce data at a sampling frequency of 192KHz using two channels. This is also close to 1,96 in the advanced digital audio conference held in Japan. It is recommended to be the next, the largest sampling frequency indispensable for audio systems. Therefore, if audio data has been recorded on DVD-Audio, the audio that can be reproduced by a DVD player is significantly improved compared to that reproduced from DVD-Video. The object of the present invention is to provide DVD_audio for storing channels that are limited by the data conversion speed in digital PCM. The channels are sampled at the maximum sampling frequency and quantized with the maximum number of bits. Another object of the present invention is 3 tan _ _ ^ ^ private for a DVD-audio to compress: 3 digits of code digits, the encoding system and linear conversion speed within linear pcm The limited frequency # θ I + is taken from -t, ^, and leads to take the sampling frequency of the large sampling frequency and the maximum number of bits to be 3: and store them. The present invention has another object to be recorded in the linear PCM. Dv]) Another object of the present invention is to provide a DVD player for playing audio and its playing method. Is to provide a DVD player for broadcasting

The sample should be adjusted to the limits of the group. That is, the audio sample data of each audio packet starts with the first byte of S2n. The number of audio samples within a group is always even. Therefore, the linear pulse code modulation in the D VD-audio format is processed within the architecture and audio architecture groups. This DVD-Audio can use a sampling frequency of 192KHZ7. The basic rules of linear pulse code modulation can be set according to Table 18. Table 18 Sampling frequency (fs) 48KHz / 44.1KHz 96KHz / 88.2KHz 192KHz / 176 4KH7 The sampling phase will be all frequencies in all stream codes at the same time. Application (Zero: 50ps, Pole: 15ps) When fs is 19 2KHz, an audio architecture contains 32 samples. An audio architecture group is equivalent to 1/30 of a second in DVD-Video. The sampling frequency of 96KHz is used to achieve multiple frequencies to store audio data. When using 48KHZ sampling frequency and 6-bit quantized recording of linear pulse code modulation (PCM) audio data, 13 channels can be obtained and used to record the current multi-channel music. However, when using the sampling frequency of ΐ92κΗζ and 24-bit quantization, you can only have 2 channels for recording audio.

Detecting abnormal conditions, the program proceeds to 6 2}, or vice versa, the program returns to decode the next data. After the audio stream code is completely decoded by the audio decoding circuit 41 3, the system controller 31 丨 controls the digital processor 3 16 and the audio output circuit 3 17 to convert the decoded audio data into an analog signal. Therefore, the DVD of the present invention includes a video title setting (VIDE0_TS) and audio title setting (AUDE0_TS) directory so that it can be distinguished from DVD-video data by checking the valid data stored in the audio title setting (AUDE0_TS) directory. DVD_audio. DVD_Audio can record audio data samples with maximum quantization and 24-bit. Also, audio channels can be extended significantly. Therefore, by copying the audio data in the DVD audio, it is possible to copy a high-quality audio signal, which is suitable for multi-channel music. The number of channels is affected by the speed of data transfer, the sampling frequency, and the number of quantization bits. This is extended by using an encoding algorithm. When the linear pulse code modulation data is sampled at a sampling frequency of 192KHz, it is divided into 96KHz linear pulse code modulation data and i92KHz data.

The DVD-video player reads the video title setting (VIDE0_TS) directory to copy 96KHz. That is, by recording a title to audio title setting (AUDE0_TS) and video title setting (VIDEO_TS), the DVD audio player can copy data at 192KHZ, and the DVD video player can copy data at 96KHz. Furthermore, the current music material supplied to the DVD at a sample rate of 44.1 KHz should be converted to 48KHz music material in order to provide it using the traditional DVD-video format. Unfortunately, the audio data may be degraded during the conversion process. According to the present invention, a DVD can support an audio sampling frequency of 44 · 1KΗζ within the DVD-audio. It is therefore possible to record audio data because it is not converted at the sampling frequency and provided with the video data, thereby providing high-quality audio sound. Processing Leopard: A general DVD-audio player should be connected to the 24-bit data of 1922.02, because the general-purpose frequency does not have the same characteristics as DVD-audio.
