Abstract

<P>PROBLEM TO BE SOLVED: To provide an audio disk whose reproduction is simple and whose operability is good for a user when mainly recording audio signals. <P>SOLUTION: Each ACB (audio contents book) unit is composed of a leading audio control pack (A-CONT pack), and a plurality of A packs and V packs succeeding to it. In the A-CONT pack, information for managing the audio signals of succeeding A packs are arranged like the TOC information of a CD. Audio data are arranged in the A pack and, for example, closed caption (CC) data other than the audio data are arranged in the V pack in addition to video data. The ACB unit is composed of the arbitrary number of packs equivalent to 0.5 to 1.0 sec, and the A-CONT packs are fundamentally arranged in 0.5 sec unit of audio time. <P>COPYRIGHT: (C)2003,JPO

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention
Data using DVD format
The present invention relates to a recording method for an audio disc having a structure. [0002] A conventional optical disc for audio reproduction is
A CD (compact disk) is known. Ma
In addition, DVD (digital
Video disc) is known. [0003] However, DVD
(Hereinafter referred to as DVD-video), the video signal is mainly
Since the audio signal is recorded as a slave, the following problems
There is. (1) The audio signal is integrated with the video signal
Therefore, the recording capacity of the audio signal is small. (2) The time of the audio signal cannot be managed.
No. (3) Simple character information such as song titles can be extracted
Absent. In addition, compared to video, audio users
The use of TOC (television) is similar to CD
Table of contents)
A simple reproduction method is required. However, DVD-Video
In the navigation control pack (CONT
Packs) and multiple video (V) packs and audio
(A) Video content block unit by pack
To play V and A packs in CONT packs
Record audio signals primarily for more control
Can be easily reproduced by the user
However, there is a problem that the usability is poor. [0005] In the case of DVD-video, time management is used.
Since this is performed only in units of video frames, the audio signal
Try to record as audio compared to video
Since continuity of signals is important, real-time management is difficult.
Problem. The present invention has been made in view of the above problems, and has
Easy playback for users when mainly recording numbers

You. On the other hand, the audio of the second embodiment
For DVDs, use a DVD video disc player.
The basic format is shown in Fig.
It is configured based on the DVD video standard shown in (a).
You. The VCB unit (VCBU) is shown in FIG.
A-CONT pack is not included as shown
Packs, a relatively large number of A packs and a relatively small number of V packs
It is composed of a pack. This ACBU is V
VCBU is abbreviated with the first A pack after the pack
Any number of packs of 0.4 to 1.0 seconds at the same interval
It is configured. Here, VCBU is the DVD video standard.
The case is also called VOBU. Then, the ACBU supplies the A-CONT pack.
Since they are not included, the A-CONT
ACD and ASD packets contained in the packet
Is the VMG (video manager) and VT shown in FIG.
S (video title set)
You. Alternatively, as shown by the broken line in FIG.
AMG and ATS that are added and added in accordance with TS
Placed on both. These AMG and ATS are shown in FIG.
Since it has the same function as AMG and ATS shown in (b),
Description is omitted. Here, the ACD packet of the first embodiment
Is provided for each ACB unit (every 0.5 to 1.0 seconds).
Since it is provided in the A-CONT pack
Number of screens of data can be accommodated,
In the embodiment, a VMG (video manager) or a VTS (video
Video title set).
Restricted, therefore titles per song or movement
Only a relatively small amount of data is accommodated. Also,
The audio playback control information shown in detail in
May be accepted. The ACD area in the ACD packet
A is a character of the first language as in the first embodiment (FIG. 5).
To have data of "1" and the character "2" in the second language
, But instead, as shown in FIG.
Omitting the data related to "2", the 48-byte generation
Ral information area and song name as shown in FIG. 6, for example
The so-called "audio navigation" of
294 bytes for the character "1" in one language for
Area and audio playback control information area of 294 bytes
May be used. The area of the character "1" is the first
93 byte name space area as in the embodiment
And two free space areas of 93 bytes each,
It consists of a 15-byte data pointer area.
You. The contents of the audio reproduction control information area are optional.
For example, audio data for 10 types of 25 bytes each
Audio playback control information area (250 bytes) and 44 bytes
Of the reservation area. These audio re-
The raw control information indicates that the music arranged in the A-pack
Is played, for example, the genre (class
Rock, jazz, rock, BGM)
Even if it is a genre, the performance status, recording status,
The sound quality during playback should be the best depending on the ambient air etc.
Data recommended by all professional mixers. Hold Eri
If the number of audio signal channels is 6,
It is possible to mix down the number of files to 2 and play back in stereo
The mixing coefficient is stored. Also, when seamlessly reproducing the A-pack
The ASD is shown in FIG.
As described above, the 8-byte data in the first embodiment (FIG. 7)
Current number information and 16-byte current time information are omitted.
And that amount is used as a reserved area (76 bytes).
ing. For this reason, as detailed as the first embodiment,
Display and playback control are not possible, but DVD video disc
Since the layer can be played back, as in the first embodiment, the DV
Only D audio disc players can play, DVD
Widespread use of discs that video disc players cannot play
A valid audio disc during the transition period
Can be realized. Next, referring to FIG.
The configuration will be described in detail. This CONT pack is DV
