Description

In the present invention, data is recorded when dubbing and recording data from a first portable recording medium such as a CD-DA (Compact Disc Digita Audio) to a second recording medium such as a hard disk drive (HDD). Storage device and storage method for managing data such as music using a database, acquiring additional information such as song names and album names from an external server as an information site such as the Internet based on the database, and automatically registering them in the database It is about.

As a device corresponding to a recording medium on which audio data is recorded, a CD player, an MD (MINI DISC) recorder / player, and the like are widely used.
As dubbing recording (copying) of audio data or the like on the user side, for example, an operation of dubbing a song recorded on a CD to an MD may be performed.
In recent years, it has also been proposed to record music recorded on a portable recording medium such as a CD or MD on an HDD (Hard Disk Drive) so that the HDD can be used in the form of a music server, for example. ing.

In CD and MD, for example, one piece of music or the like is recorded as one program (also referred to as a track), and one or a plurality of programs (tracks) are recorded, and the whole is made into one album.
In the dubbing operation to another recording medium using the CD or MD as a recording source, for example, the entire CD, that is, an album unit may be dubbed, or only a track designated by the user may be dubbed.

  Meanwhile, some conventional audio devices can record not only music data on a recording medium but also additional information corresponding to the entire album and music. The additional information herein includes character data such as album names and song names, recording date and time, copyright information (ISRC: International Standard Recording Code), and the like.

For example, in a mini-disc system, a song name, album name, recording date and time, etc. can be recorded in correspondence with each recorded song or the entire disc.
However, character data such as song titles must be input by the user using the operation system of the MD recording device, which is often troublesome, and many users can enter music without entering song names or album names. There are many cases of enjoying.
Further, although it has been possible to connect a PC (personal computer) and a recording device and use a PC keyboard to assist in character input, it does not necessarily reduce the effort of the user.

  Furthermore, in order for the user to input character data such as a song name, it is natural that the user must know, for example, which track on which CD the recorded song is dubbed. For example, when a user selectively dubs a song from a large number of CDs, the song name of each song recorded on the MD cannot be known unless the user is familiar with the song (that is, the song name cannot be input). Many cases).

Furthermore, in the case of an apparatus that dubbs a large number of CDs to the HDD as described above, the correspondence between the music dubbed on the HDD and the CD that is the recording source is completely unknown to the user. The case will be very much.
Currently, as an external server such as a music information site such as the Internet, there is a service that provides a song name recorded on a certain CD and other additional information. For example, which CD is a CD album dubbed and recorded on the HDD If you don't know, you won't be able to receive even the services of the external server.

  In other words, in recent years, various types of recording systems have made it possible to record additional information in association with data such as music recorded on a recording medium. In many cases, the information to be relied upon is not actually recorded, and the value is often not effectively used.

  Therefore, in the present invention, in accordance with such circumstances, data is transferred from a first portable recording medium such as a CD-DA to a second recording medium having a huge recording capacity such as a hard disk drive (HDD). In an audio device and audio data management method that can record dubbed data and manage the dubbed data, the device automatically acquires additional information (even without user operation) and manages registration corresponding to data such as music The purpose is to improve the usability and convenience of the user.

The present invention relates to a reproducing means for reproducing music data and a recording medium on which the management data of the music data is recorded, music data reproduced by the reproducing means and management data, and identifying the music data A single program composed of a header portion in which information is recorded and the music data; storage means for storing a database file generated based on the identification information; and the management data corresponding to the music data; Communicates with an external server that stores different additional data, and controls the communication means to transmit the identification information stored in the storage means to the external server, and based on the identification information, the external information The additional data of the music data stored in the storage means transferred from the server is received, the storage means is controlled, and the received additional data is received. And a control means for updating the database file based on chromatography data, and said the identification information recorded in the database file, on the basis of the management data reproduced by said reproducing means is reproduced by said reproducing means It is further provided with notification means for determining whether or not the data to be recorded has been recorded in the storage means and notifying when it is determined that the data has been recorded .

Further , based on the identification information recorded in the header portion of the program and the management data reproduced by the reproducing means, it is determined whether the data reproduced by the reproducing means has been recorded in the storage means, and recording is performed. It is further provided with a notification means for performing a notification when it is determined that it is completed.

In the present invention, the storage unit further includes a plurality of programs, and the control unit obtains additional data for the plurality of programs from the external server.
Furthermore, an instruction means for instructing the external server to acquire additional data is provided, and the control means controls the communication means based on an acquisition instruction from the instruction means to execute an additional data acquisition operation.
Further, the recording medium is a CD, and the management data is TOC data.
The additional data is at least one of a song name, album name, genre, composer, conductor, lyrics, and image data of music data.

Furthermore, the storage method of the storage device comprising the storage means for storing the music data and the program of the present invention, the communication means capable of communicating with the external server, and the control means for controlling transmission and reception with the external server, Generated on the basis of data and a recording procedure on which the management data of the music data is recorded, music data reproduced by the reproducing means and management data, and identification information of the music data is recorded A single program composed of a header part and the music data, a storage procedure for storing a database file generated based on the identification information, and additional data different from the management data corresponding to the music data A communication procedure for communicating with the external server to be stored; and the identification information stored in the storage procedure by controlling the communication procedure The additional data of the music data transmitted to the external server and stored in the storage means transferred from the external server based on the identification information is received, the storage procedure is controlled, and the received additional data A control procedure for updating the database file based on the data, and data reproduced in the reproduction procedure based on the identification information stored in the database file and the management data reproduced by the reproduction procedure Is recorded in the storing procedure, and a notification procedure for performing a notification when it is determined that recording has been performed is further executed.

As can be understood from the above description, in the present invention, each data dubbed and recorded from the first recording medium to the second recording medium is managed by the database means, and the first recording is performed here. By managing the media identification information, it is possible to obtain additional information from an external server via communication means, and automatically registering the obtained additional information in the database means without any user input. For example, a song title and other additional information can be obtained. Therefore, there is an effect that the user can easily obtain the track name, album name, and information associated with the album without inputting characters by a troublesome operation system. In particular, when a music server using an HDD is constructed, the convenience for the user is remarkably improved, which is very suitable.
For example, in a large-capacity recording medium such as HDD, it is possible to store more songs than ever before, so it is possible to automatically add song names and album names to recorded songs. Obviously, it will be a great help for users to find the tracks they want to hear from the HDD.

  The identification information is generated based on the management information recorded on the first recording medium, so that the first recording medium can be clearly identified. Can be discriminated clearly, so that accurate additional information can be obtained. Of course, the user does not need to set identification information.

Further, the program unit data recorded on the second recording medium has pointer information indicating a database file corresponding to the data, that is, database management can be realized in program (track) units. Has been. Therefore, suitable data management can be realized regardless of the unit such as the CD album of the dubbing source.
For example, even if the song structure managed for each album in the second recording medium is destroyed by the user's editing operation, for example, track movement or track deletion, the song name is accurately associated with the song by managing the song in units of tracks. Maintains the state of managing information.
In addition, even when the user creates an album that collects only favorite songs from a large number of CDs, etc. on the second recording medium, additional information such as song names can be accurately managed by managing the songs in units of tracks. it can.

In addition, by having a data group management file for managing one or a plurality of data as data of the program unit as one data group to be reproduced in a predetermined order, the second recording medium can be used. For example, data such as a large number of music pieces can be managed as one album, and the convenience of reproduction for the user is improved.
Further, when the data group management file has pointer information indicating one or a plurality of database files to which each data of the data group to be managed corresponds, the database file is also referred to from the data group management file. it can.

Further, the control means causes the additional information about the entire first recording medium to be received from the external server by causing the communication means to transmit the identification information of the first recording medium managed by the database means to the external server. By storing the received additional information in correspondence with the identification information in the database means, the additional information can be obtained in units of albums, for example.
Further, additional information on a part of the program is received, and the received additional information is stored in correspondence with the identification information in the database means, so that additional information can be obtained in units of tracks.
Accordingly, an appropriate additional information acquisition operation is realized depending on the data configuration on the second recording medium, the album configuration, or the presence of a track for which additional information has already been acquired. For example, if some data of a data group managed as one album has already acquired additional information, it is not necessary to acquire additional information from the external server for that data, and such operation is omitted. Therefore, efficient additional information acquisition can be realized. Particularly in the case of home use and the like, it is a great advantage for the user that the communication time is shortened by an efficient operation of acquiring additional information.

Hereinafter, as an embodiment of a storage device and a storage method of the present invention, a dubbing device for automatically dubbing and recording a program (for example, music data also called a track) reproduced from a CD onto an HDD, the dubbed data A device having a function capable of managing a database will be described. The description will be given in the following order.
In this embodiment, the dubbing apparatus and the personal computer are connected to constitute the data management apparatus of the present invention. Of course, the present invention is not limited to such a form.

1. Configuration of dubbing equipment

FIG. 1 shows a configuration of a dubbing apparatus 100 of this example. The dubbing apparatus 100 includes a system controller 1, a CD playback unit 2, an HD recording / playback unit 3, an audio input / output unit 4, an operation unit 5, a display unit 6, and an interface 7.
The dubbing apparatus 100 and the personal computer 101 are connected to construct a data management apparatus. In this case, the personal computer 101 mainly functions as a communication means.

In the dubbing apparatus 100, the system controller 1, the CD playback unit 2, and the HD recording / playback unit 3 can communicate with each other various control signals CS. For example, a bus connection configuration may be used. The system controller 1 transmits a control signal CS to the CD playback unit 2 and the HD recording / playback unit 3 to cause the CD playback unit 2 and the HD recording / playback unit 3 to execute required operations.
The CD playback unit 2 and the HD recording / playback unit 3 transmit to the system controller 1 an answer signal for the control signal CS, an operation status (status), information such as a subcode and TOC described later, and other necessary information.

The system controller 1 is formed by a microcomputer and controls the overall operation by transmitting a control signal CS.
An input is given to the system controller 1 from the operation unit 5. The operation unit 5 includes a power key, an eject key, a playback key, a pause key, a stop key, a music selection key, a recording key, and the like, and a user performs an arbitrary operation. The system controller 1 instructs the CD playback unit 2 and the HD playback unit 3 to perform an operation by the control signal CS in response to an operation by the operation unit 5.
In addition, the user can specify the CD track number to instruct playback from an arbitrary song, the so-called program playback can be specified by the user to play the song in order, or the song can be played in a random order called shuffle playback. Operations such as playback are also possible.
Further, an operator that can input characters may be prepared so that the user can input additional information such as a song title.

A display unit 6 is connected to the system controller 1, and the system controller 1 gives display data to the display unit 6 to execute necessary display. For example, the display unit 6 displays information relating to the CD loaded in the CD playback unit 2 such as the total performance time, the elapsed time of the song being played, the remaining performance time of the song being played back, the remaining performance time of the entire song, etc. The time information and the track number of the song being played are displayed.
In the case of a disc on which a disc name (album name) or track name (song name) is recorded, the disc name or track name is displayed.

The CD reproducing unit 2 is a part that loads a CD-DA corresponding to the first recording medium and reproduces it. Although the detailed configuration will be described later, audio data S1 (PCM digital audio data) reproduced from the CD is supplied to the audio input / output unit 4 and the HD recording / reproducing unit 3.
Note that the CD playback unit 2 is a part that can play music data for a CD disc, and for the sake of explanation, it corresponds to CD-DA, but for example, other than CD methods such as CD-R and CD-RW If music data is recorded on this kind of disc, it can be reproduced in the same manner. In addition, there is a CD text disc in which text data is recorded in the subcode as one form of CD-DA. In this case, the text data can be reproduced from the subcode along with the reproduction of the music data.
In this example, the case where the first recording medium is a CD is taken as an example, but the first recording medium may be another type such as MD, memory card, DAT (digital audio tape), and the like. In this case, an MD playback unit, a memory card playback unit, a DAT playback unit, etc. may be provided instead of (or in addition to) the CD playback unit 2.

The HD recording / reproducing unit 3 includes a HDD serving as a large-capacity second recording medium, and is a part that records and reproduces data on the HDD. The HDD as the second recording medium has a very large capacity compared to the CD as the first recording medium, such as a capacity of several tens GB.
Although the configuration of the HD recording / reproducing unit 3 will be described later, audio data S1 from the CD reproducing unit 2 and audio data S2 (PCM digital audio data) from the audio input / output unit 4 are input to the HD recording / reproducing unit 3. The HD recording / reproducing unit 3 can record these audio data S1 and S2 on the HDD. The audio data S1 and S2 are music data signals compliant with IEC60958, for example.
Also, the audio data S3 reproduced from the HDD can be output to the audio input / output unit 4.

  The audio input / output unit 4 is a part for inputting / outputting audio data, and outputs audio data reproduced from the CD reproducing unit 2 or the HD recording / reproducing unit 3 to a speaker system or other devices, or Audio data (digital audio data or analog audio signal) supplied from another device is input. The system controller 1 controls the input / output path by the voice input / output unit 4 in accordance with the switching control signal CSW. Details will be described later.

  The system controller 1 is connected to the personal computer 101 via the interface 7. For example, the personal computer 101 and the system controller 1 communicate with each other with a clock asynchronous serial signal. Connection is performed by a serial cable or a USB cable normally used in a computer. An application operating on the personal computer 101 can control the system controller 1 to cause the dubbing apparatus 100 to execute a required operation.

The personal computer 101 has a function of performing network communication such as the Internet through a predetermined communication line, and can communicate with an external server (not shown).
The external server referred to here is an information site that provides a service that provides additional information about a commercially available CD, searches for the corresponding CD according to the identification information of the CD, and additional information corresponding to the CD. For example, the album name, the title of the recorded song, ISRC, etc. are provided.
The personal computer 101 can acquire additional information by communicating with such an external server.
In order to execute communication processing for acquiring additional information, the personal computer 101 has application software for automatically acquiring additional information. As will be described later with reference to FIGS. When 1 performs linkage processing, an additional information automatic acquisition operation that is a characteristic operation of this example is realized.
In addition, the application running on the personal computer 101 can display such information visually and in an easy-to-understand manner by using a GUI for music information on a CD or information recorded on an HDD. This application allows users to edit the information. For example, a GUI display can be operated on a monitor display (not shown) connected to the personal computer 101.

In this example, the personal computer 101 is described as having a function as a communication unit and a part of a control unit for automatically acquiring additional information. However, the dubbing apparatus 100 includes a network communication unit, An example is also conceivable in which the system controller 1 also performs communication operation control so that connection with the personal computer 101 is unnecessary.

2. Configuration of CD playback unit

FIG. 2 shows the configuration of the CD playback unit 2. The disc 90 is a CD loaded in the CD playback unit 2.
The disk 90 is rotationally driven by the spindle motor 22 at a constant linear velocity (CLV) during the CD reproducing operation. Then, the data recorded in the pit form on the disk 90 is read by the optical head 23 and supplied to the RF amplifier 25.

In order to read data from the disk 90, a laser diode (not shown) serving as a laser light source, a photodetector for detecting reflected light, an objective lens serving as an output end of the laser light, and laser light are provided in the optical head 23. Is provided to the disc recording surface through an objective lens, and an optical system for guiding the reflected light to a photodetector is provided.
The objective lens is held movably in the tracking direction and the focus direction by a biaxial mechanism.
The entire optical head 23 can be moved in the disk radial direction by a thread mechanism 24.

In addition to the reproduction RF signal, the RF amplifier 25 generates a focus error signal and a tracking error signal.
These error signals are supplied to the servo circuit 27. The servo circuit 27 generates a focus drive signal, a tracking drive signal, and a thread drive signal from the focus error signal and the tracking error signal, and controls operations of the biaxial mechanism and the thread mechanism 24 in the optical head 23.
The servo circuit 27 generates a sled drive signal according to the low frequency component of the tracking error signal and the access instruction signal from the CD controller 21, and controls the operation of the sled mechanism 24 to move the optical head 23.
The servo circuit 27 generates a spindle drive signal based on the spindle error signal and spindle kick / brake signal supplied from the decoder 26 or the CD controller 21 and controls the operation of the spindle motor 22.

The reproduced RF signal output from the RF amplifier 25 is supplied to the decoder 26. The decoder 26 performs EFM demodulation, CIRC decoding, etc., and decodes the information read from the disk 90 into 16-bit quantized digital audio data S1 of 44.1 kHz sampling. The digital audio data S1 is supplied to the HD recording / reproducing unit 3 and the audio input / output unit 4 as shown in FIG.
The decoder 26 also extracts control data such as TOC and subcode, which are supplied to the CD controller 21 and used for various controls.

The CD controller 21 is a microcomputer that controls the CD reproducing unit 2.
When reproducing the disk 90 (CD), it is necessary to read the management information recorded on the CD, that is, the TOC. The CD controller 21 determines the number of tracks recorded on the disc 90, the address of each track, etc. according to this management information, and performs playback operation control. For this reason, the CD controller 21 reads out by executing the reproducing operation on the innermost circumference side of the disk on which the TOC is recorded when the disk 90 is loaded, and stores it in, for example, the internal RAM, and thereafter reproduces the disk 90. It can be referred to during operation.

  When the disc 90 is CD text, text data is recorded in a subcode forming TOC data. The CD controller 21 reads this text data when reading the TOC and stores it in the internal RAM. Note that there is a mode in which text data is recorded in a subcode in the program area instead of the so-called TOC area. In this case as well, text data is extracted together with the subcode data extracted as the program (track) is played back. Data will be imported.

As shown in FIG. 1, the CD controller 21 can communicate various control signals CS with the system controller 1 and the HD recording / reproducing unit 3 (HD controller 31 in the HD recording / reproducing unit 3 described later).
For example, when the system controller 1 performs operations such as CD playback, FF (fast forward), REW (fast reverse), AMS (cue), pause (pause), stop, and dubbing from the operation unit 5. Transmits the operation information to the CD controller 21. In accordance with the operation information, the CD controller 21 controls each part of the CD reproducing unit 2 so that an operation intended by the user is executed.
The CD controller 21 transmits to the system controller 1 the operating state of the CD playback unit 2, TOC information and text information read from the disk 90, and time information (address) during CD playback.
The system controller 1 grasps the operating state of the CD playback unit 2 by transmission from the CD controller 21 and causes the display unit 6 to execute various displays as described above based on the TOC and subcode information. Can do.
Although a specific example will be described in detail later, the CD controller 21 transmits / receives various information to / from the HD recording / reproducing unit 3 during the dubbing operation.

3. Configuration of HD recording / playback unit

FIG. 3 shows the configuration of the HD recording / playback unit 3. The HD recording / reproducing unit 3 is provided with an HDD (Hard Disk Drive) 32 as a large-capacity second recording medium.
The HD controller 31 is a controller that controls the operation of the HD recording / reproducing unit 3. Inside the HD controller 31, a mechanism called a file system for implementing access, reading and writing to the HDD 32 is mounted. For example, a FAT32 file system is used.

As shown in FIG. 1, the HD controller 31 can communicate various control signals CS with the system controller 1 and the CD playback unit 2 (CD controller 21).
For example, the system controller 1 gives a dubbing instruction and other instructions to the HD controller 31 when dubbing playback data from the CD playback unit 2 to the HDD 32 as will be described later.
From the CD controller 21, TOC information and text information read from the disc 90 to be reproduced are transmitted. The TOC information or the like is used for generating disc identification information in a database to be described later.
The HD controller 31 also transmits information related to the operation state (status) and the dubbing operation to the system controller 1 and the CD controller 21.

The HDD 32 writes and reads data under the control of the HD controller 31. In particular, digital audio data S1 reproduced by the CD reproducing unit 2 and digital audio data S2 supplied from the audio input / output unit 4 are recorded in the HDD 32 after being subjected to predetermined processing. The recorded data is managed by the FAT32 file system.
The recorded data is read by the HD controller 31 and supplied to the audio input / output unit 4 for output.
For example, when the user performs an operation to be played by designating music recorded on the HDD 32 from the operation unit 5, the system controller 1 transmits the operation information to the HD controller 31. Then, the HD controller 31 reproduces data such as the designated music piece from the HDD 32 and supplies it to the audio input / output unit 4 as audio data S3.
As will be described later, in order to manage the data recorded in the HDD 32, a database capable of recording CD identification information and additional information is constructed in the HDD 32.
The HD controller 31 can refer to and update the database stored in the HDD 32 when necessary.

The audio compression encoding / decoding circuit 33 and the buffer memory 34 are parts for processing the recording data and reproduction data of the HDD 32.
The HD recording / playback unit 3 receives the digital audio data S1 from the CD playback unit 2 or the digital audio data S2 from the audio input / output unit 4, and when these digital audio data S1 and S2 are input. The audio compression encoding / decoding circuit 33 performs data compression processing. For example, ATRAC3 compression processing is performed. The compressed digital audio data is stored in the buffer memory 34 and recorded in the HDD 32 under the control of the HD controller 31.
During playback from the HDD 32, data read from the HDD 32 by the HD controller 31 is stored in the buffer memory 34. The data is read from the buffer memory 34 at a predetermined rate and subjected to data expansion processing in the audio compression encoding / decoding circuit 33. As a result, the compression processing of the ATRAC3 method is released, and the digital audio data S3 is output to the audio input / output unit 4 as normal digital audio data S3.

Note that the compression method is not ATRAC3, and another compression method such as MPEG audio may be used, or recording may be performed on the HDD 32 without compression.
Further, the data recorded in the HDD 32 may be encrypted, and the decryption process may be performed during reproduction.

4). Audio input / output configuration

FIG. 4 shows the configuration of the voice input / output unit 4. As shown in the figure, an analog audio signal output terminal 41, an analog audio signal input terminal 42, a digital audio data output terminal 43, a digital audio data input terminal 44, D / A converters 45 and 46, and an A / D converter. 47, a digital interface 48, and switches 49 and 50 are provided.

  The audio input / output unit 4 is supplied with digital audio data S1 reproduced by the CD reproducing unit 2 and digital audio data S3 reproduced by the HD recording / reproducing unit 3.

While the CD reproducing unit 2 is performing the reproducing operation, the system controller 1 connects the switch 49 to the tc terminal by the switching control signal CSW.
Therefore, the digital audio data S1 from the CD reproducing unit 2 is converted into an analog audio signal by the D / A converter 45, supplied to the output terminal 41 via the switch 49, and output as an analog audio signal.
While the HD recording / reproducing unit 3 is performing the reproducing operation, the system controller 1 connects the switch 49 to the th terminal by the switching control signal CSW.
Therefore, the digital audio data S3 from the HD recording / reproducing unit 3 is converted into an analog audio signal by the D / A converter 46, supplied to the output terminal 41 through the switch 49, and output as an analog audio signal.
An analog audio signal from the output terminal 41 is amplified by a power amplifier circuit and output to a speaker, or supplied to another device as a line output.

  The digital audio data S1 reproduced by the CD reproducing unit 2 and the digital audio data S3 reproduced by the HD recording / reproducing unit 3 are also supplied to the digital interface 48. The digital interface 48 encodes the supplied digital audio data S1 or S3 into a transmission data form as a digital interface format and outputs the encoded data from the output terminal 43. That is, the playback sound can be transmitted to other devices in the form of digital audio data.

  In the HD recording / reproducing unit 3, not only the digital audio data S 1 from the CD reproducing unit 2 but also the digital audio data S 2 supplied from the audio input / output unit 4 can be recorded in the HDD 32. The digital audio data S2 is output as follows.

First, when an analog audio signal from an external device is input to the input terminal 42, the analog audio signal is converted into digital audio data having a sampling frequency of 44.1 kHz and a quantization bit number of 16 bits by an A / D converter 47. Is done. At this time, the system controller 1 connects the switch 50 to the ta terminal by the switching control signal CSW, so that the output of the A / D converter 47 is supplied to the HD recording / reproducing unit 3 as the digital audio data S2.
When digital audio data from an external device is input to the input terminal 44, the input data is decoded by the digital interface 48. At this time, the system controller 1 connects the switch 50 to the td terminal by the switching control signal CSW, so that the output decoded by the digital interface is supplied to the HD recording / reproducing unit 3 as the digital audio data S2.
Also, the digital audio data S1 reproduced by the CD reproducing unit 2 can be supplied to the HD recording / reproducing unit 3 as the digital audio data S2 through the digital interface 48.

5. CD subcode and TOC

Next, a subcode recorded together with main data on a CD format disc and a TOC recorded in the lead-in area will be described.

The minimum unit of data recorded on a CD disc is one frame. One block is composed of 98 frames.
The structure of one frame is as shown in FIG.
One frame is composed of 588 bits, with the first 24 bits being the synchronization data and the subsequent 14 bits being the subcode data area. After that, data and parity are arranged.

This block is composed of 98 frames to form one block, and the subcode data extracted from the 98 frames is collected to form one block of subcode data (subcoding frame) as shown in FIG. Is done.
The subcode data from the first and second frames (frame 98n + 1, frame 98n + 2) at the head of the 98 frames is a synchronization pattern. In the third frame to the 98th frame (frame 98n + 3 to frame 98n + 98), 96-bit channel data, that is, subcode data of P, Q, R, S, T, U, V, and W is formed. .

  Of these, the P channel and the Q channel are used for access management. However, the P channel only indicates a pause portion between tracks, and finer control is performed by the Q channel (Q1 to Q96). The 96-bit Q channel data is configured as shown in FIG.

  First, the 4 bits of Q1 to Q4 are used as control data, and are used for identifying the number of audio channels, emphasis, CD-ROM, and whether or not digital copying is possible.

Next, 4 bits of Q5 to Q8 are set to ADR, which indicates the mode of sub Q data.
Specifically, the mode (sub-Q data content) is expressed by 4 bits of ADR as follows.
0000: Mode 0 ... Basically, the sub-Q data is all zero (used in CD-RW).
0001: Mode 1 ... Normal mode.
0010: Mode 2 ... Indicates the catalog number of the disc.
0011: Mode 3... ISRC (International Standard Recording Code) or the like.
0100: Mode 4... Used with CD-V.
0101: Mode 5: Used in a multi-session system such as CD-R, CD-RW, CD-EXTRA, etc.

  The 72 bits Q9 to Q80 following ADR are sub-Q data, and the remaining Q81 to Q96 are CRC.

The address is expressed by the sub-Q data when the mode 1 is indicated by ADR.
The sub-Q data and TOC structure in the case of ADR = mode 1 will be described with reference to FIGS.
In the lead-in area of the disc, the sub-Q data recorded there becomes TOC information.
That is, the sub-Q data of 72 bits Q9 to Q80 in the Q channel data read from the lead-in area has information as shown in FIG. FIG. 7 (a) shows the structure of FIG. 6 (b) in the lead-in area in detail for the 72-bit sub-Q data portion.
The sub-Q data has 8-bit data and expresses TOC information.

First, a track number (TNO) is recorded with 8 bits of Q9 to Q16. In the lead-in area, the track number is fixed to “00”.
Subsequently, POINT (point) is written in 8 bits of Q17 to Q24.
MIN (minutes), SEC (seconds), and FRAME (frames) are indicated as the elapsed time in the lead-in area with 8 bits each of Q25 to Q32, Q33 to Q40, and Q41 to Q48.
Q49 to Q56 are set to “00000000”.
Furthermore, PMIN, PSEC, and PFRAME are recorded with 8 bits each of Q57 to Q64, Q65 to Q72, and Q73 to Q80. The meaning of PMIN, PSEC, and PFRAME is determined by the value of POINT.

  When the value of POINT is "01" to "99", the value of POINT means a track number. In this case, in PMIN, PSEC, and PFRAME, the start point (absolute time address) of the track of the track number is They are recorded as minutes (PMIN), seconds (PSEC), and frames (PFRAME).

When the value of POINT is “A0”, the track number of the first track is recorded in PMIN. Further, specifications such as CD-DA (digital audio), CD-I, and CD-ROM (XA specification) are distinguished by the value of PSEC.
When the value of POINT is “A1”, the track number of the last track is recorded in PMIN.
When the value of POINT is “A2”, the start point of the lead-out area is indicated as an absolute time address (minute (PMIN), second (PSEC), frame (PFRAME)) in PMIN, PSEC, and PFRAME.

For example, in the case of a disc on which 6 tracks (6 programs: 6 songs) are recorded, the data is recorded as the TOC by such sub-Q data as shown in FIG.
Since it is a TOC, the track numbers TNO are all “00” as shown.
Block NO. Indicates the number of one unit of sub-Q data read as block data (sub-coding frame) of 98 frames as described above.
Each TOC data has the same contents written over three blocks.
As shown in the figure, when POINT is “01” to “06”, the start points of the first track # 1 to the sixth track # 6 are indicated as PMIN, PSEC, and PFRAME.

  When POINT is “A0”, “01” is indicated as the first track number in PMIN. Also, the disc is identified by the value of PSEC, and is “00” in the case of a normal audio CD. When the disc is a CD-ROM (XA specification), PSEC = “20”.

In addition, the track number of the last track is recorded in PMIN at the position “POINT” of “POINT”, and the start point of the lead-out area is shown in the positions “POINT” “A2” of PMIN, PSEC, and PFRAME.
After block n + 27, the contents of blocks n to n + 26 are repeatedly recorded.

  In the program area and the lead-out area where music and the like are recorded as track # 1 to track #n, the sub-Q data recorded therein has the information shown in FIG. FIG. 7B shows the structure of FIG. 6B in the program area and the lead-out area in detail for the sub-Q data portion of 72 bits.

In this case, first, a track number (TNO) is recorded with 8 bits of Q9 to Q16. That is, each of the tracks # 1 to #n has a value of “01” to “99”. In the lead-out area, the track number is “AA”.
Subsequently, an index is recorded with 8 bits of Q17 to Q24. The index is information that can further subdivide each track.

MIN (minutes), SEC (seconds), and FRAME (frames) are indicated as the elapsed time (relative address) in the track with 8 bits each of Q25 to Q32, Q33 to Q40, and Q41 to Q48.
Q49 to Q56 are set to “00000000”.
8 bits of Q57 to Q64, Q65 to Q72, and Q73 to Q80 are AMIN, ASEC, and AFRAME, respectively, which are minute (AMIN), second (ASEC), and frame (AFRAME) as absolute addresses.
The absolute address is an address that is continuously assigned from the beginning of the first track (that is, the beginning of the program area) to the lead-out area.

Basically, the subcode and the TOC formed by the subcode are as described above, but the subcode can further include various kinds of information.
For example, in the case of CD text, text information is stored using R to W of the above-described P, Q, R, S, T, U, V, and W subcode data.

6). File structure recorded on HDD

Various files recorded in the HDD 32 will be described with reference to FIG.
For example, data such as music that is input to the HD recording / playback unit 3 as the digital audio data S1 and S2 and recorded in the HDD 32 is recorded as one music data file MDF in units of tracks (one unit of music). become.
FIG. 9 shows a plurality of music data files MDF1, MDF2,.

Also, a reproduction music order management file PFM is constructed to manage each music data file MDF in one data group, that is, a predetermined reproduction music order as one album. FIG. 9 shows a plurality of reproduction song order management files PFM1, PMF2,... Each managing one album.
The reproduction music order management file PFM is entirely managed as an album management file.
Various forms of the album management file and each reproduction song order management file PFM can be considered. For example, as shown in FIG. 12A, each reproduction song order management file PFM1, PMF2 is represented as a block in one album management file. .. May be formed, and as shown in FIG. 12B, the album management file indicates a pointer to each reproduction song order management file PFM, that is, a recording position on the HDD 32, a file name, and the like. It is possible to manage the reproduction music order management files PFM1, PMF2,...

For example, in FIG. 9, if the music data files MDF1, MDF2, MDF3, and MDF4 are tracks recorded by dubbing from a CD album containing four songs, the playback song order management file PFM1 is stored in this music data. The files MDF1, MDF2, MDF3, and MDF4 are formed to be managed as tracks TK1, TK2, TK3, and TK4 constituting one album.
The management as an album is not performed only when, for example, the entire CD album is dubbed and recorded, but a plurality of songs arbitrarily selected by the user and recorded in the HDD 32 are recorded in the playback song order management file PFM. It can also be specified and managed as an album. That is, the user can construct an arbitrary plurality of music data files MDF as an album in an arbitrary song order.
Further, one music data file MDF may be managed as a plurality of reproduction music order management files PFM. That is, a certain piece of music is managed as one piece of music constituting each album in a plurality of albums.

A database is constructed in the HDD 32 as described above. This database manages additional information and the like regarding the music data file MDF with the database file DBF as one unit.
One database file DBF is formed corresponding to one CD album. Each music data file MDF has a pointer indicating the corresponding database file DBF.
For example, if the music data files MDF1, MDF2, MDF3, and MDF4 are tracks dubbed and recorded from a CD album containing four songs as described above, the CD that is the dubbing source is stored in the database. A database file DBF1 corresponding to the album is formed.
The music data files MDF1, MDF2, MDF3, and MDF4 correspond to the database file DBF1 as shown in the figure.

FIG. 10 shows the structure of the music data file MDF.
One music data file MDF with a certain file name “MDF ***” is roughly composed of a header part and a music data part.
In the header portion, various attributes and file sizes (number of sound units) of the music data file MDF, and other necessary management data are recorded. As described above, the database file number and the database file name are recorded as a pointer that points to one database file DBF in the database to which the music data file MDF corresponds. Further, a track number (TNO) indicating which track number of the music data file MDF is managed in the corresponding database file DBF is also recorded. As will be described later, since the database file is formed based on the TOC of the CD, this track number corresponds to the track number originally recorded in the CD album (managed by a playback song order management file described next). It does not necessarily match the track number).

  Actual audio data is recorded in the music data portion. The audio data itself is a set of units called a sound unit SU, and one sound unit has a length of about 23 milliseconds. The sound units (SU001) to (SU (n)) form audio data of one musical piece.

FIGS. 11 (a) and 11 (b) show structural examples of the reproduction song order management file PMF.
As shown in FIG. 11A, a reproduction song order management file PFM to which a certain file name “PMF ***” is attached is roughly composed of a header part and a song order management part. In the header part, an album number and other necessary management data are recorded.

The song order management unit manages a plurality of music data files MDF managed as albums by the reproduction song order management file PFM as a predetermined order, that is, tracks TK # 1 to TK # m as the reproduction song order.
Specifically, as shown in the figure, file names of a plurality of music data files MDF constituting the album are described as tracks TK # 1 to TK # m.
For example, as illustrated in FIG. 9, when the reproduction song order management file PFM1 manages the music data files MDF1, MDF2, MDF3, and MDF4 as tracks TK1, TK2, TK3, and TK4 constituting one album, In the song order management unit, the file names of the music data files MDF1, MDF2, MDF3, and MDF4 are recorded in order.

FIG. 11B is another example of the reproduction song order management file PFM, which is an example in which the pointer of the database file DBF is recorded in the header portion in addition to the information of FIG.
As described above with reference to FIG. 9, the reproduction song order management file PFM manages each music data file MDF constituting the album, and each music data file MDF indicates the corresponding database file DBF.
The example of the present embodiment will be described on the premise of such a structure, but as shown in FIG. 9 as another example, the reproduction music order management file PFM corresponds to the music data file MDF managed. The database file DBF may be indicated. When doing so, as shown in FIG. 11B, the corresponding database file number and database file name are recorded.

Note that one database file and one reproduction song order management file PFM do not always correspond 1: 1.
That is, one database file DBF corresponds to one CD album that is the dubbing source, and manages additional information about the entire CD album or recorded music.

  In response to the dubbing from the CD, one database file DBF is formed for the CD. For example, even when only one song from a certain CD is dubbed to the HDD 32, the dubbed music data is recorded. The database file DBF formed corresponding to the file MDF is formed in a form (described later in FIG. 13) corresponding to the entire CD that is the dubbing source.

On the other hand, the reproduction music order management file PFM manages one or a plurality of music data files MDF as music recorded in the HDD 32 as one album.
Therefore, when all the songs are dubbed from the CD album and the music data file MDF of all the songs is managed as one album by the playback song order management file PFM, all songs (music data file MDF) managed by the playback song order management file PFM are managed. ) Corresponds to a common database file DBF, and therefore one database file DBF corresponds to the reproduction song order management file PFM. However, when the user selects and dubbs music from a large number of CDs and manages it as an album with one playback song order management file PFM, each song managed by the playback song order management file PFM is stored in a different database file DBF. In order to cope with this, a plurality of database files DBF are associated with the reproduction music order management file PFM. In such a case, the database file number and file name in FIG. 11B are shown according to each track.

7). The database

As shown in FIG. 9, the database is constructed as an aggregate of individual database files DBF. The database file DBF employs a configuration in which CD identification information and additional information about a CD album and a program (track) recorded therein are recorded.

FIG. 13 shows the contents of one database file DBF.
As described above, one database file DBF is formed corresponding to one CD. The individual contents in the database file DBF generated with a certain database file name “DBF ***” are as follows.

Database file number This database file number is a number given to each database file in the database.

-Album name slot (1)
This is an area for entering an album name for single-byte characters.
・ Album name slot (2)
This is an area for entering a 2-byte character album name.
・ Artist name slot (1)
This is an area for entering the artist name for single-byte characters.
・ Artist name slot (2)
This is an area for entering the artist name for double-byte characters.
・ Album INFO
This is an area for storing additional information corresponding to the entire album other than the album name and artist name. For example, this is an area in which information such as an album producer, a production company, and a genre can be stored. Also, image data such as album jacket images, artist images, and image images can be considered.
Recording date and time This is an area for storing information of year / month / day / hour / minute / second recorded in the HDD 32.
The above-described album name to recording date and time are managed as additional information corresponding to an entire CD album.

Subsequently, an area of information obtained as TOC data of the CD is prepared.
Total number of tracks in the album This is an area indicating the number of tracks recorded on the CD shown in the TOC data described with reference to FIGS. Specifically, the value of the last track number of the disc shown in FIG.
-Start point of track TK # 1 ... Start point of TK # m The start point (address value by absolute time) of each track of the CD is indicated. For example, when the TOC data is that of FIG. 8, the start point values shown for each of the tracks # 1 to # 6 are recorded as they are in the corresponding area of the database file.
-Lead-out start point Shows the CD lead-out start point (address value based on absolute time). For example, when the TOC data is that shown in FIG. 8, the value of the lead-out start point shown in the figure is recorded as it is in the area of the database file.
From the total number of tracks to the start point of the lead-out, the contents of the TOC data of the CD are recorded almost as they are.
The TOC data in which the number of tracks included in the CD, the absolute time (start point) at which the track is started, and the start point of the lead-out are written in the form of minutes, seconds, and frames, all these values are different CDs. Are unlikely to be the same. Therefore, these TOC data can serve as identification information for a CD with a specific title. In this example, this point is used as identification information for a corresponding CD in the database file DBF.

  Note that the above-described external server that provides services on the Internet determines a CD based on identification information using the TOC information of the CD, and provides additional information about the CD. Therefore, as will be described later, in this example, when additional information is requested from an external server, identification information formed from this TOC data is transmitted.

Following such identification information, an area for recording additional information corresponding to each track recorded on the CD is formed.
-Name slot (1) of track TK # 1 to name slot (1) of TK # m
This is an area for storing a 1-byte character track name for each of the tracks TK # 1 to TK # m.
-Name slot (2) of track TK # 1 to name slot (2) of TK # m
This is an area for storing a 2-byte character track name for each of the tracks TK # 1 to TK # m.
Recording date / time of track TK # 1 to recording date / time of TK # m This is an area for storing the date / time recorded in the HDD 23 for each of the tracks TK # 1 to TK # m.
・ ISRC of truck TK # 1 to ISRC of TK # m
This is an area for entering ISRC data for each of the tracks TK # 1 to TK # m.
-INFO of track TK # 1 to INFO of TK # m
This is an area in which additional information other than the above is entered for each of the tracks TK # 1 to TK # m. For example, this is an area where information such as the genre of a song, composer, conductor, lyrics, image data, and the like can be stored.

Such a database file DBF is generated in response to the dubbing of music data from a CD, and information of the portion serving as the identification information is recorded from the TOC data of the CD at that time. However, in most cases, not all information in the database file DBF is recorded when the music data is dubbed and recorded on the HDD 32 as the music data file MDF. For example, since the HD controller 31 cannot obtain the album name, song name, ISRC, INFO, etc. when dubbing from a CD, these are left blank (invalid data).
If the additional information such as the song name is not managed in the database file DBF, the user cannot recognize the music data file MDF recorded on the HDD 32 by the song name. As described above, the additional information is automatically taken from the external server and registered in the database file DBF.

For example, when the disc 90 to be reproduced is CD text, if there is a song name or the like as text data read from the subcode, the data is registered in the database file during dubbing corresponding to the track or disc. Is possible.
Of course, when the user arbitrarily inputs a song name or the like, it can be registered as additional information. However, in this example, user input is unnecessary due to automatic registration processing.

8). Dubbing operation

Next, a dubbing operation realized by the control of the system controller 1, the CD controller 21, and the HD controller 31 in the dubbing apparatus 100 will be described with reference to FIGS.

In step F101, the system controller 1 monitors whether the user performs an operation for instructing the dubbing of the CD → HDD 32 in the operation unit 5.
If there is a dubbing operation, in step F102, the user's operation information is transmitted to the CD playback unit 2 (CD controller 21), and the TOC information of the disc 90 currently loaded in the CD playback unit 2 is transferred to the HD controller 31. Give instructions to do.
The operation information is information on what type of dubbing the user has instructed. That is, the information indicates whether all the music on the CD is to be dubbed, or one or more tracks are designated and only that track is dubbed.

  When the CD controller 21 obtains the dubbing operation information notification and the TOC transfer instruction from the system controller 1 in step F201, the TOC data read from the currently loaded disc 90 is converted into the HD according to the instruction from the system controller 1. Transfer to the controller 31.

When receiving the TOC data from the CD controller 21, the HD controller 31 searches the database stored in the HDD 32 in step F301. That is, the identification information described in FIG. 13 is generated from the contents of the input TOC data, and the same identification information is recorded as each database file DBF in the database using the generated identification information. Search whether there is.
When the database file DBF having the same identification information is found, dubbing from the disc 90 currently loaded in the CD playback unit 2 has been performed in the past, and the database file DBF has already been created for the disc 90. This is the case. On the other hand, when the database file DBF having the same identification information is not found, the dubbing from the disc 90 currently loaded in the CD playback unit 2 is performed for the first time this time.

Therefore, if the search result is not applicable, the HD controller 31 proceeds from step F302 to F303 to create a new database file DBF with the created identification information and add it to the database. Then, the process proceeds to Step F304.
If the corresponding database file DBF is found as a search result, the process proceeds from step F302 to F304.
In step F304, the system controller 1 is notified that the database file DBF related to the current dubbing is newly prepared or searched, and the preparation for the correspondence is completed on the database.

When a corresponding database file is found as a database search result, all the tracks recorded on the current disk 90 may already be recorded as music data files MDF in the HDD 32. In addition, when the user designates dubbing only a part of the tracks on the disc 90 this time, the tracks may already be recorded as the music data file MDF.
In such cases, the current dubbing operation is not necessary. Accordingly, although not shown in FIG. 14, in order to avoid redundant dubbing, the HD controller 31 transmits a dubbing unnecessary notification to the system controller 1, and the system controller 1 displays a message to the user on the display unit 6. By doing so, the user's will may be reconfirmed.
In the database file DBF, the recording date / time of the tracks recorded on the CD to the HDD 32 is recorded as described above, and the track number on the CD (disc 90) has already been recorded on the HDD 32 as the music data file MDF. Therefore, the HD controller 31 can determine whether or not the dubbing is necessary by receiving the track number related to the current dubbing from the system controller 1 or the CD controller 21. Of course, information on whether or not each track is recorded in the HDD 32 may be recorded in the database file DBF.

When the system controller 1 receives a notification of completion of database correspondence from the HD controller 31, it issues a dubbing preparation instruction in step F103. That is, the CD controller 21 is instructed to prepare for the reproduction operation related to the dubbing instructed by the user, and the HD controller 31 is instructed to prepare for recording.
In step F202, the CD controller 21 prepares for reproduction on the disk 90 in accordance with an instruction from the system controller 1. That is, as a playback operation preparation according to a user operation, a playback operation for the entire disc 90 (that is, continuous playback from the first song to the last song) or a track playback operation designated by the user is prepared. When preparation for reproduction is completed, a preparation completion notice is transmitted to the system controller 1 as step F203.
In step F305, the HD controller 31 prepares for recording on the HDD 32 in accordance with an instruction from the system controller 1. That is, preparation is made to record the digital audio data S1 reproduced and supplied from the CD reproducing unit 2 in the HDD 32. At this time, the corresponding database file DBF is opened, and the database file name for music information management of the disc 90 to be dubbed is stored. Of course, this is the database file DBF searched in step F301 or the database file DBF newly created in step F303.
When the recording preparation is completed, a preparation completion notice is transmitted to the system controller 1 as step F306.

Subsequently, the processing of each unit shifts to the processing shown in FIG.
When the system controller 1 detects that the CD playback unit 2 and the HD recording / playback unit 3 are ready, the system controller 1 instructs the CD controller 21 to start playback and the HD controller 31 to start recording in step F104.

  In response to this, the CD reproducing unit 2 performs the reproducing operation of the disc 90 as step F204, and the reproduced digital audio data S1 is supplied to the HD recording / reproducing unit 3. The CD controller 21 performs the reproduction process of step F204 until the reproduction of the disk 90, that is, the reproduction of all tracks is completed or the reproduction of one or more tracks designated by the user is completed in step F205. I do.

  The HD controller 31 performs recording processing to the HDD 32 in step F307 in response to a recording start instruction from the system controller 1. That is, predetermined processing is performed on the digital audio data S1 supplied from the CD playback unit 2, and an operation of recording as a music data file MDF in units of sound units is performed.

The recording process in step F307 is shown in detail in FIG.
At the time of starting the recording process, the HD controller 31 first sets a new music data file MDF as step F351. In step F352, the digital audio data S1 supplied from the CD playback unit 2 is subjected to predetermined processing such as data compression, and recording processing is performed so as to write the music data file MDF in units of sound units SU. It will be a thing.
During a period in which data is written to one music data file MDF, the HD controller 31 monitors a track change or recording end instruction in step F353.
When the track change, that is, when the tune (track) reproduced by the CD reproducing unit 2 shifts to the next tune, or when a recording end instruction is issued from the system controller 1, the process proceeds to step F354.

There are various methods for detecting a track change, and there are a method for monitoring the track change on the HD controller 31 side and a method for the CD controller 21 notifying the HD controller 31 of the track change.
For example, if the digital audio data S1 supplied to the HD recording / playback unit 3 is digital data compliant with the IEC60958 format, the HD controller 31 can monitor the digital audio data S1 if the Ubit track number included therein is monitored. The track change timing can be detected.
Further, since the CD controller 21 can naturally recognize the track change from the subcode obtained during the reproduction of the disc 90, the CD controller 21 transmits the track change notification to the HD controller 31 in accordance with the transmission timing of the digital audio data S1. The controller 31 can grasp the track change timing for the input digital audio data S1.

  When a track change is detected, when the digital audio data S1 at that track change point is recorded, the recording of the music data portion (see FIG. 10) of the music data file MDF into which the sound unit SU has been written is completed. Therefore, in step F354, the HD controller 31 writes information of the header part for the music data file MDF, and completes recording of the music data file MDF. Specifically, various management data described in FIG. 10 is written as a header portion, and a database file number, a database file name, and a track number on the database file are written as a pointer indicating the corresponding database file DBF. The database file number and database file name are the number and file name indicating the database file DBF opened in step F305. The track number is the track number of the track on the disk 90.

Then, returning from step F355 to F351, a new music data file MDF is set for the next track, and in step F352, the digital audio data S1 is written into the music data file MDF in units of sound units SU. Perform the recording process.
By such processing, the music data file MDF is formed in the HDD 32 in units of tracks of the disk 90.

The CD controller 21 transmits a CD playback end notification to the system controller 1 when playback of the disc 90 is completed. The HD controller 31 may also be notified.
When the system controller 1 detects the end of the CD reproduction based on the notification from the CD controller 21, the system controller 1 instructs the HD controller 31 to end the recording in step F105.
The HD controller 31 detects a recording end instruction in the process of step F353 in FIG. 16, and in this case, the music data for the last recorded track is obtained by performing the same process as step F354. The file MDF is completed. In this case, the process proceeds from step F355 to the recording end process in step F308 of FIG.

As the recording end process in step F308, the management state setting corresponding to the generation of one or more music data files MDF, for example, necessary processes such as FAT update and directory setting, and one or more of this time A reproduction song order management file PFM for managing the music data file MDF as one album is generated. Still further, recordable information is written in the database file DBF. For example, the recording date and time information is written in the database file DBF. If the disc 90 is a CD text or the like and additional information such as song name information is obtained, data such as album name and song name can be written in the database file DBF.
Then, after completing the above recording end processing, a series of processing at the time of dubbing is ended.

The above dubbing process has been described as a process when the user performs an operation of dubbing all or a part of a track from a disc 90 as a certain CD. In some cases, you can select your favorite songs from the CD and copy them sequentially. In such a case, the processes shown in FIGS. 14 and 15 are repeated for each CD.

9. Additional information acquisition operation

By the above dubbing operation, the music data file MDF is formed in the HDD 32 in units of tracks, and the database file DBF corresponding to each music data file MDF exists in the database, and further, the reproduction song order management file PFM. Thus, the music data file MDF is managed as an album. That is, the file structure described with reference to FIG. 9 is constructed, but additional information such as a song title is not recorded in the database file DBF.
In this example, for the database file DBF in which no additional information is recorded, the additional information is automatically registered by the process described below.

The automatic additional information acquisition operation is performed by the linkage operation of the dubbing apparatus 100 and the personal computer 101, and the process will be described with reference to FIGS. In each figure, processing of an application operating on the personal computer 101 and processing on the dubbing apparatus side (particularly processing performed by the system controller 1 and the HD controller 31) are shown.
An application activated on the personal computer 101 (hereinafter referred to as a PC application) is a function for presenting information about a music data file MDF recorded in the HDD 32 to a user, a GUI operation support function, a network communication function, and a system controller 1. It has a control function for. In the following description, “display” refers to a monitor display in the personal computer 101, but as another example, for example, the display unit 6 of the dubbing apparatus 100 can be used. The user operation is performed using a keyboard, a mouse, or the like on the personal computer 101 side. Similarly, the operation unit 5 may be used as another example.

The user can use the personal computer 101 to request to display album information recorded in the HDD 32 as information of the music data file MDF recorded in the HDD 32.
When the PC application detects an album information display request from the user in step F401 in FIG. 17, the PC application requests album information from the dubbing apparatus 100 in step F402.
For example, the PC application captures the file name of the playback song order management file PFM existing in the HDD 32 from the dubbing apparatus 100 at the time of startup or the like so that the number of “albums” existing in the HDD 32 can be grasped at a minimum. To. Then, an album number or the like corresponding to each reproduction song order management file PFM is displayed on the display. In response to this display, the user selects an arbitrary album and requests detailed information about the album.
Therefore, in step F402, information about the album (playback song order management file PFM) selected by the user is obtained.

In step F501, the dubbing apparatus 100 confirms the contents of the reproduction song order management file PFM related to the request from the PC application, and grasps each music data file MDF managed by the reproduction song order management file PFM.
In step F502, the database file DBF corresponding to each music data file MDF is confirmed from the pointer of the database file recorded in each music data file MDF. In this case, if each music data file MDF managed by the reproduction song order management file PFM is dubbed from one CD, one database file DBF corresponding to each music data file MDF is stored. The database file DBF is confirmed.
On the other hand, when each music data file MDF managed by the reproduction song order management file PFM is selectively dubbed from two or more CDs to form one album, a database corresponding to each music data file MDF. Two or more database files DBF are confirmed as the file DBF.

  At this time when the corresponding database file DBF is detected, whether or not additional information such as a song name for each music data file MDF is registered by checking the contents of the detected one or more database files DBF. Can be determined.

If additional information such as a song name is not registered for all the music data files MDF for the currently played song order management file PFM, that is, the album, the process proceeds from step F503 to F504, and the song order management is performed. The contents of the file PFM are transmitted to the PC application side as album information. That is, in this case, information such as the file name of the music data file MDF managed by the reproduction music order management file PFM is transmitted to the personal computer 100 side.
On the other hand, if additional information such as a song name has already been registered for a part or all of the music data file MDF of the currently reproduced reproduction order management file PFM, that is, the album, the process proceeds from step F503 to F505. Then, the contents of the reproduction music order management file PFM and the contents of the additional information registered in the corresponding database file DBF are transmitted to the PC application side as album information. That is, in this case, the file name and the like of the music data file MDF managed by the reproduction song order management file PFM is transmitted to the personal computer 100 side, and the music name and the like of the music data file MDF in which additional information is registered. The additional information is also transmitted.

When the album information is transmitted in the process of step F504 or F505 of the dubbing apparatus 100, the PC application displays the content of the transmitted album information on the display as step F403.
For example, a list of file names of music data files MDF as songs included in an album for which the user has requested information is displayed. In particular, when additional information is transmitted as step F505, a song name or the like can be displayed together with the file name or instead of the file name. Of course, other additional information can also be displayed.

Of course, if the song name is displayed, the user can easily grasp the songs included in the album. For example, the user can select and play the album or a desired song in the album, or specify another album. Thus, operations such as obtaining album information can be performed.
Of course, it is possible even if the song name is not displayed, but when a large number of music data files MDF are recorded in the HDD 32, it is determined which music data file MDF is which song for the user. It is difficult to do. Also, additional information in album units is convenient for the user if displayed, but inconvenient if not displayed.
Therefore, in the PC application, the user can request processing for automatically registering information on albums and music data files MDF to which album names and song names are not added.
In this case, the user designates a certain track in the album (or the additional information is not registered), and processing for acquiring additional information such as the album name and the song name of the music included in the album in album units. It is possible to selectively instruct a process of acquiring additional information such as a song name for the track by automatically selecting only the track).

When the user instructs automatic acquisition of additional information in units of albums, the processing of the PC application proceeds from step F404 to F405, and notifies the dubbing apparatus 100 that the additional information automatic acquisition processing in units of albums is to be executed. The process proceeds to the process of FIG.
When the user instructs automatic acquisition of additional information in units of tracks, the processing of the PC application proceeds from step F406 to F407 and notifies the dubbing apparatus 100 that the additional information automatic acquisition processing in units of tracks is to be executed. The process proceeds to the process of FIG.
The dubbing apparatus 100 also shifts to the processing in FIG. 18 in the case of the additional information automatic acquisition processing in units of albums in response to the notification of the PC application in step F405 or F407, and in the case of the additional information automatic acquisition processing in units of tracks. The process proceeds to 19.

When the user performs another operation by the GUI operation on the display on the display, the PC application shifts from step F408 to another process, that is, a process according to the operation. For example, the user gives an instruction to play an album or track, gives an instruction to add / delete / change the order of music data files MDF included in the album as an album editing process, or a music data file MDF recorded in the HDD 32. When an operation for generating a new album (that is, a reproduction song order management file PFM) is extracted, processing corresponding to that is performed.
Since these are not directly related to the additional information automatic acquisition process, detailed description thereof is omitted.

The PC application and the process of the dubbing apparatus 100 when the user requests the additional information automatic acquisition process for each album will be described with reference to FIG.
In this case, first, in step F409, the PC application requests the dubbing apparatus 100 for a database file name to be processed this time.
On the other hand, in step F507, the dubbing apparatus 100 side stores the database file name (or database file number) recorded in each music data file MDF managed in the current target album (playback song order management file PFM). May be sent to the PC application.

When receiving the database file name corresponding to each music data file MDF, the PC application determines in step F410 whether all the database file names (or database file numbers) transmitted are the same.
If the database file names do not all match, the current target album (playback song order management file PFM) manages the music data file MDF dubbed from a certain CD. It will not be what you have.
That is, the reproduction song order management file PFM does not manage an album corresponding to a certain CD.
Therefore, in such a case, the process proceeds to step F413 to stop the additional information automatic acquisition process in units of albums, display a message indicating the cancellation on the display, inform the user, and end the process.

If all database file names match in step F410, the PC application requests the data content of the database file DBF itself from the dubbing apparatus 100 in step F411.
In response to this, the dubbing apparatus 100 side transmits the contents of the requested database file DBF to the PC application in step F508.
At this time, the contents of the database file DBF transmitted to the PC application may be all data, but may be only the above-described identification information portion generated based on the TOC data.

The PC application can grasp the number of tracks of the original CD album from the contents of the database file DBF. This is because the identification information includes information on the total number of tracks in the album as described in FIG.
Here, the number of tracks of the original CD is compared with the number of tracks (number of music data files MDF) managed by the currently reproduced reproduction order management file PFM to determine whether or not they match. .
Here, when the number of tracks is the same, for example, all tracks of the CD are dubbed and recorded on the HDD 32, and the song order management file PFM is a collection of songs having the same contents as all the tracks recorded on the original CD. This is a case where each music data file MDF on the HDD 32 is managed. (However, the song order may not match due to the user's editing operation.)

On the other hand, if the number of tracks does not match, the music (music data file MDF) managed in the playback song order management file PFM that is currently the target is a song that has been recorded on the same CD. It does not include all the songs on the CD.
In such a case, the original CD and the album (playback song order management file PFM) on the HDD 23 that is the current target are not completely matched, and the process proceeds to step F413, where the album unit is recorded. The additional information automatic acquisition process is canceled, a message indicating the cancellation is displayed on the display and notified to the user, and the process ends.

  That is, in the processing example of FIG. 18, when the music included in the original CD and the album (reproduction song order management file PFM) on the HDD 23 that is the current target completely match, additional information in album units is automatically The acquisition process is executed, and for this reason, the actual additional information automatic acquisition process is started when the number of tracks matches in step F412.

First, in step F414, the PC application connects to a network line, and connects to a predetermined external server that provides the additional information providing service.
In step F415, the TOC data recorded in the database file DBF, that is, the above-described identification information is transmitted, and additional information such as an album name and a song name for the CD indicated by the identification information is requested.
The external server discriminates a specific CD album from a large number of commercially available CD albums using TOC data as a key for discrimination, and transmits additional information about the CD album.
When the additional information is received from the external server in this manner, the PC application displays it on the display in step F416.
For example, instead of the album name or song name displayed as the file name on the HDD 32 until then (or along with the file name), the actual album name, song name, etc. are displayed.

As a result, the user can clearly know the contents of an album stored in the HDD 32. However, the name is actually registered in the database file DBF, and is displayed with the name after that. An operation for instructing whether or not to perform is performed. Specifically, in step F417, the PC application displays a message asking whether or not additional information such as the name being displayed can be registered on the display, and the user performs an operation to answer it. If the user does not require registration, the process ends. If the user requests registration, the process proceeds to step F418, and an update request for the database file DBF is transmitted to the dubbing apparatus 100 side.
In response to this, the dubbing apparatus 100 side prepares to update the database file DBF in step F509, and returns a preparation completion notice when the preparation is completed.

Subsequently, in step F419, the PC application transmits the contents of the database file DBF, that is, additional information received from the external server, to the dubbing apparatus 100 side, and the dubbing apparatus 100 side transmits the additional information transmitted in step F510 to the relevant information. An update operation is performed in which the database file DBF is written.
When the update is completed, an update completion notification is transmitted to the PC application in step F511, and the process ends.

Through the processing as described above, additional information is automatically acquired from the external server in units of albums, and update processing is performed in which the additional information acquired in the corresponding database file DBF is registered.
For example, even if only the database file number, the identification information based on the TOC data, and the recording date / time are recorded in the database file DBF at the time before the processing, the processing shown in FIG. Additional information is registered in each name slot, ISRC, INFO, etc. shown in FIG.

FIG. 19 shows the process of the PC application and the dubbing apparatus 100 when the user requests the additional information automatic acquisition process for each track as step F406 in FIG.
In this case, first, in step F429, the PC application requests the dubbing apparatus 100 for a database file name corresponding to the target track or tracks. The target track is a track specified by the user. Alternatively, the PC application may automatically designate a track whose song name cannot be displayed on the display as a target track.

  In step F512, the dubbing apparatus 100 side responds to the request from the PC application with the database file name (or database file number) recorded on the target track (music data file MDF) and the database file. Are sent to the PC application.

When receiving a reply from the dubbing apparatus 100, the PC application first checks in step F421 whether or not there is any database file name corresponding to the target track (music data file MDF).
The case where the corresponding database file name does not exist for all of the target tracks means that all of the current target track (music data file MDF) has been dubbed from a CD or the like in the above-described processing of FIGS. This is the case where there is no corresponding database file having identification information. For example, it may be due to dubbing from an external device having no TOC data transmission function.
If the database file DBF does not exist, additional information cannot be registered. Therefore, the processing is stopped in step F422, a message indicating the cancellation is displayed on the display and notified to the user, and the processing is ended.

If at least one database file name is returned, the PC application requests the dubbing apparatus 100 side for the data contents of the returned one or more database files DBF in step F423.
In response to this, the dubbing apparatus 100 side transmits the contents of the requested database file DBF to the PC application in step F513.
At this time, the contents of the database file DBF transmitted to the PC application may be all data, but may be only the above-described identification information portion generated based on at least TOC data.
The PC application can grasp the identification information of the dubbing source CD album for each target track from the contents of the database file DBF. Of course, since the track number on the database file DBF recorded in the music data file MDF is also obtained by the transmission in step F512, the track number in the CD album from which the target track is dubbed can be grasped.

By the way, the database file DBF does not exist for all the target tracks in step F421, and there may be a case where the database file DBF does not exist for a part of the target tracks even when the processing is not stopped.
If the database file DBF does not exist for some of the target tracks, the process proceeds from step F424 to F425 to indicate to the user that additional information cannot be obtained for some of the tracks on the display. At this time, a track in which the database file DBF does not exist is excluded from the target of the additional information automatic acquisition process.

When the contents of the database file DBF, specifically the identification information, are obtained for the target track, the PC application starts actual additional information automatic acquisition processing.
That is, the PC application establishes a network line connection in step F426 and connects to a predetermined external server that provides the additional information providing service.
In step F427, the TOC data recorded in the database file DBF, that is, the identification information described above and the track number of the target track are transmitted, and the song name of the target track and other additional information are requested in the CD indicated by the identification information. To do.
The external server discriminates a specific CD album using the TOC data as a key, extracts additional information of a track required by the personal computer 100 from the transmitted track number, and transmits the additional information.

  When there are a plurality of target tracks, the PC application transmits identification information and a track number for each, and the external server transmits additional information corresponding to each.

When the additional information is received from the external server in this manner, the PC application displays it on the display in step F428.
For example, the actual song name or the like is displayed for the track that has been displayed with the file name on the HDD 32 until then.

As a result, the user can clearly know what song a track of an album stored in the HDD 32 is.
And confirm the user's will for the actual registration. That is, in step F429, the PC application displays on the display a message asking whether or not the additional information such as the currently displayed name that is currently displayed can be registered in association with the track, and the user performs an operation to answer it. If the user does not require registration, the process is finished as it is. If the user requests registration, the process proceeds to step F430, and an update request for the database file DBF is transmitted to the dubbing apparatus 100 side.
In response to this, the dubbing apparatus 100 side prepares to update the database file DBF in step F514, and returns a preparation completion notice when the preparation is completed.

Subsequently, in step F431, the PC application transmits the contents of the database file DBF, that is, the additional information received from the external server, to the dubbing apparatus 100 side. On the dubbing apparatus 100 side, the additional information transmitted in step F515 is An update operation is performed in which the database file DBF is written.
When a plurality of database files DBF are to be updated, each database file DBF is similarly updated.
When all the updates are completed, the dubbing apparatus 100 side transmits an update completion notification to the PC application in step F516 and ends the process.

By the processing as described above, additional information is automatically acquired from the external server in units of tracks, and update processing is performed in which the additional information acquired in the corresponding database file DBF is registered.
For example, when the additional information is not registered in the database file DBF for a part of the music data file MDF managed by a certain reproduction song order management file PFM at the time before such processing. Further, additional information about the music data file MDF (track) is acquired and registered in the corresponding database file DBF.

As described above, the additional information automatic acquisition process is executed in units of albums or tracks, so that the user does not need to input a song name or the like for the songs dubbed in the HDD 32. After the automatic registration, the music name and album name for each music data file MDF are displayed (display in step F403 in FIG. 17), so that the content (music) recorded in the HDD 32 can be easily obtained. Can grasp.
Of course, if additional information is registered, it is displayed, so that an automatic registration request operation is not performed again without the user's knowledge, and useless communication connection is avoided.
