Description

V. 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.

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.

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.

However, in the present invention, it is called audio; and the shoulder method extends the sampling frequency to ig2KHz, = yuan :: channel data is compressed to about 4: 1.

The linear pulse code modulation reproduced by the video player is shown in Table 7. Of course, the compressed and encoded digital theater system data is played by the DVD_Video player and only the digital theater system stream code specified by the DVD-Video is copied. For example, it is generally believed that the titles to be stored on DVD can be displayed in Table 23, Table 23, Sampling Frequency, Quantization Bits, Number of Channels, Remarks 48KHz 16 8 Channel Title 1 96KHz 16 4 Channel Title 2_ 96KHz 24 2 Channel Title 3 96KHz 24 4 Channel title 4 192KHZ 24 2 Channel title 5 Then, the video title settings (VIDE0_TS) and video manager (VMG) are recorded based on the attributes and location information of titles 1 to 3 instead of titles 4 and 5. In contrast, a. The audio title setting (VIDE0_TS) and audio manager (VMG) of DVD-Audio are recorded according to all the information of titles 1 to 5, because titles 1 to 3 can meet the specifications of DVD-video and DVD-audio at the same time. However, titles 4 and 5 only comply with DVD-Audio specifications. Therefore titles 4 and 5 can only be played by DVD-audio players. If there is an available space in the data area, titles 4 and 5 can be recorded in this acquired space at a reduced sampling frequency, quantization bits, and channel number, respectively, and titles 4 and 5 are stored in the audio title settings (VIDE0_TS) and Audio Manager (VMG).

If the compression-encoded digital theater system (DTS) does not meet the DVD-video specifications regarding the data transfer rate, the number of channels, the sampling frequency of the original data, and the number of quantized bits, this information can only be recorded in the audio title settings (AUDI0_TS) and Audio Manager (AMG) and cannot be recorded in Video Title Settings (VIDEO_TS) and Video Manager (VMG). That is, only the digital theater system (DTS) stream code meets the DVD-Video specification can be recorded in the video title setting (VIDEO-TS) and the video manager (VMG). In order to copy DTS stream codes that fail to meet the DVD-video specifications, their encoding must comply with the transfer rate, channel number, sample channel, and quantization bit number specified by the DVD-Video. If it is stored, it must be recorded in the video title setting (VIDE0 —TS) and Video Manager (VMG).

However, audio data exceeding the specifications of DVD-Video data such as a sampling frequency of 192KHz and more than 8 channels must be changed to be copied via a DVD-Video player. Therefore, the production of the disk is as follows: When the content of a title to be recorded on the disk is within the DVD-Video specification, any one of the Video Manager (VMG) and the Audio Manager (AMG) is kept for Make the video title setting (VIDE0_TS) and audio title setting (AUDI0_TS) direct the file through the video manager (VMG) or audio manager (AMG).

At the same time, if any titles to be recorded on the disc have audio stream codes that do not conform to the DVD-Audio specification, keep the Video Manager (VMG) and Audio Manager (AMG) together, and the Video Manager (Vmg) Unable to record title information that does not meet DVD.-video specifications. Of course, the audio manager (am◦) does not record information on the title. This title has changed sampling frequency, quantized number of bits, and number of channels to be compatible with the DVD-Video player. However, the structure of the DVD-Audio Audio Manager (AMG) and Audio Titles (AUDI0_TS) is completely different from the structure of the DVD-Video Video Manager (VMG) and Video Title Setting Information Management Table (VTSI_MAT). At the same time, 'the video manager (VMG) and the audio manager (AMG) must be prepared' and the video title settings (VIDE0-TS) and audio title settings (AUDI0-TS) are the same. Of course, the video manager (VMG) and the video title setting information management table (VTSI_MAT) will be provided with the information on the audio title that conforms to the video specifications.

, Using 16-bit, 20-bit, or 24-bit linear pulse code modulation, with sampling frequencies of 48KΗζ, 44.1KΗζ, 96KΗζ, 88 2KΗζ, 192〇ζ, or 176 4KΗζ, the largest recordable channel The number is 13 channels, and the compression ratio is *: worker. The Bit Theater System (DTS) M-down coding has a high number of quantized bits and a sampling frequency and a low compression ratio, maintaining high sound quality. As described above and referring to the twenty-seventh and twenty-ninth figures, the audio, or theta / video player determines the type of DVD based on whether valid data is stored in the audio title setting (AUMO-TS) directory. That is, the MD_audio player performs or does not perform the copy function according to whether the valid data is stored in the audio title setting (AUD 丨 〇_TS) directory. The audio / video player shown in Figure 29 performs audio or video playback functions based on whether valid data is stored in the audio title setting directory. Figure 31 illustrates the implementation of the concept of the invention and refers to the video player of Figure 29. An inserted DVD is checked by the system controller 31 in step 511, and the audio title setting (AUDIO-TS) directory is read in step 5 ^ 3. According to step 515, it is checked whether the valid data is stored in the AUDIO-TS directory. If the inserted DVD is a video, there is no valid data in the audio (AUDIO-TS) directory. That is, DVD_Video has an audio title setting (AUDIO JS) directory, but it is empty. However, if the inserted DVD is a DVD-Audio, the audio title setting (AUDIO-TS) directory contains information on the location of the audio data as shown in Figures 10 to 18c. According to step 5 1 5 to detect the valid data of the audio title setting (AUDI0-TS) directory, the system controller 3 11 determines according to step 5 丨 7 whether the inserted magnetic disk is

According to step 519, the position of the audio manager (AMG) shown in Fig. 10 and Fig. 11 can be located by reading the audio title setting (audi 0-Ts) directory. Then, the selection device 312 is moved to the position of the audio manager (AMG) in the DVD according to step 521, where the audio manager (AMG) is read to confirm the information on the location where the entire audio data is stored. As shown in Figures 10 and 11, the Audio Manager (AMG) contains information on all audio titles stored in]) VD_Audio and the attributes and location information of each title. According to steps 5 to 23, the system controller 3 to 11 checks whether there is a need to copy a specific audio title. This requirement is made by the user or by an instruction stored in DVD_Audio. Detecting the need to copy a title, the system controller 3 丨 i locates the title position on the disk based on the location information obtained from the audio manager (AMG) in step 525, and moves the selection device 312 to this in step 527 The title's audio title sets the position of the information management table (ATSI_jat) to: Read. According to step 529 ', the audio title setting information management table (ats i_mAT) is shown in Fig. 15 to Fig. 18C. After analysis, it is found that the type and attribute of the audio title to be played are determined to determine the reproduction algorithm. According to step 531 ', the audio decoding circuit 413 of the audio / video decoder 315 is set on the audio data selected from the DVD_audio according to the copy algorithm. The information required to set the audio decoding circuit 41 3 is the audio encoding mode, the sampling frequency, the number of quantization bits, and the number of channels. Finally, the selected title is decoded by the audio decoding circuit 413 in step 533. On the other hand, if there is no valid data in the audio title setting (AUD10-TS) directory according to step 515, the system controller 3 i i determines the inserted

A: \ PI302. Ptd p. 62 403896 V. Description of the invention (59) The inserted disk is DVD-Video, and the location of the video manager according to step 5 3 7 is set by reading video title (VII) E -TS) directory. Then, the selection device 312 is moved to the position of the video manager (VMG) in the DVD in step 539. The Video Manager (VMG) is read to confirm the information on the part that stores the entire video data. After that, if there is a requirement to copy the title, the video, auxiliary image, and audio data of the selected title will be broadcast according to the information stored in the video title setting information management table (VTSI-MAT). Similarly, a DVD-audio player that only copies material from a DVD-audio also performs the MD-audio steps 51 1 to 533 but stops playing the DVD-video. After setting the audio decoding circuit 413 according to the information stored in the audio title setting information management table (ATS) _MAT, the system controller 311 analyzes the audio disk group stored in the DVD audio data area from step 32. The steps presented. Once the solution of the brother 5 i: 6 1 1 ’, the system controller 3 11 directs the audio decoding circuit 4 1 3 2 to transfer the audio data to the 412 code circuit 413 which provides the counter analysis. Then, the audio frequency is divided into Japan; ^, the algorithm of the frequency resolution of the day of the departure will be on the way to the received audio data according to the system controller 311 setter 311 check step 615 to establish ^ for decoding. Here, the system control measures the abnormal state of the audio circuit ^ 1 and the operating state of the circuit 4 1 3. Upon inspection, the decoding circuit 413 stops decoding 'you, and the program proceeds to step 621 to control to stop transferring data. Stupefied, and after the stream code language analyzer 4 1 2 is controlled by the algorithm, it is expected to return to; 2. The repair is performed according to the abnormal state

403896

However, 'if the audio decoding circuit 41 3 normally performs the decoding operation in accordance with steps 6 and 5', the decoded audio data is output through the decoding output circuit 414 in step 61 7. Thereafter, the operation status of the audio decoding circuit 4 丨 3 is checked again according to step γ9. 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. Therefore, the 96KHz data is recorded by the lossless psychoacoustic encoding. The present invention uses linear Pulse code modulation records audio data at a sample rate of 192KHz in the audio title setting (AUDE0-TS) directory and records audio data at a rate of 96KHz in the video title setting (VIDEO-TS) directory by linear pulse code modulation . DVD-audio player reads audio title settings (AUDE〇_TS) through psychological sound

Description of the invention (61) The response code demodulate the data and mix it with the actual material of 96KΗζ In order to copy it into 192KHZ 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.
