TECHNICAL FIELD OF THE INVENTION
The present invention relates to a recording / reproducing system, a control device, and a management method.
[0002]
[Prior art]
2. Description of the Related Art Recording / reproducing apparatuses that record music data on a recording medium and reproduce the recorded music data have been widely used. As an example, an MD recording / reproducing apparatus using an MD (mini-disc) as a recording medium can record music data reproduced from a music CD (compact disc) on a commercially available recording MD (for example, Patent Document 1). reference).
[0003]
[Patent Document 1]
JP 2002-93046 A (Pages 4-6, FIG. 1)
[0004]
Recently, MD recording / reproducing devices conforming to the “NetMD (registered trademark)” standard for connecting to a personal computer (personal computer) are gradually becoming popular. The NetMD standard is an extended standard for music MD, and transfers music data stored on a hard disk of a personal computer to an MD recording / reproducing device and records the data on a recording MD. At this time, since the music data in a state before decoding is transferred as it is, sound quality deterioration due to decoding / encoding or the like is prevented. Further, unlike recording (recording) accompanying reproduction, since data transfer is substantial, recording ends several times to several tens times faster than during normal recording.
[0005]
Further, the NetMD standard has a strong copyright protection technology as a feature thereof, which prevents disorderly distribution of music data. Specifically, copyright protection is achieved by a check-out / check-in function.
Here, the term “checkout” refers to transferring (copying) music data from a personal computer to an MD recording / reproducing device.
On the other hand, check-in means that music data (actually, a content hash) transferred to and recorded on an MD recording / reproducing device by check-out is returned to a personal computer (transfer source personal computer). This means making the music data unusable.
The personal computer defines the limit number of check-outs (for example, three times as an initial value) for each piece of music data, and manages it appropriately. That is, each time the personal computer checks out each piece of music data, the personal computer reduces the limit number by one and prohibits the checkout of the music data exceeding the limit number. In addition, since the personal computer increases the limit number by one at the time of check-in, the user can freely transfer music data between the personal computer and the MD recording / reproducing device on condition that check-in after check-out is properly performed. Can be moved.
[0006]
[Problems to be solved by the invention]
As described above, the music data is protected by the NetMD standard (check-out / check-in function), but it is often not easy for the user to grasp the checked-out MD. In other words, the personal computer only manages the limited number of times of the stored music data and the like, and the user needs to remember the actual checkout destination of the music data.
Therefore, a user who owns a plurality of MDs often forgets the checkout destination of the music data or mistakenly stores it. Furthermore, music data that is normally recorded (recorded) and checked-out music data can be mixed in the same MD, so that the user is further confused.
[0007]
If the music data to be checked out has used up the limited number of times, the music data must be checked in from the checked-out MD.
At this time, if the checked-out MD cannot be grasped, the user needs to repeatedly check the contents of the music data recorded from a plurality of MDs in order to find the target MD, which is extremely complicated. .

BEST MODE FOR CARRYING OUT THE INVENTION
A recording / reproducing system (audio system) according to an embodiment of the present invention will be described below with reference to the drawings.
[0018]
FIG. 1 is a block diagram showing an example of a configuration of a recording / reproducing system applied to an embodiment of the present invention. As shown in the figure, this system is configured by connecting a recording / reproducing apparatus 1 and a personal computer 3 via a USB cable C.
[0019]
The recording / reproducing apparatus 1 is an audio device that conforms to the “NetMD (registered trademark)” standard. As shown in the figure, a security circuit 11, a digital signal processing circuit 12, a head driver 13, a recording head 14, a spindle It comprises a motor 15, an optical pickup 16, a feed motor 17, an RF amplifier 18, a buffer memory 19, a system controller 20, an operation unit 21, and a display panel 22.
[0020]
In other words, the recording / reproducing apparatus 1 records music data (contents) from the personal computer 3 on the disk d (MD; mini-disc) at the time of checkout according to the NetMD standard. At the time of check-in, the music data recorded on the disk d is returned to the personal computer 3 (actually, the content hash is returned and the music data is deleted from the disk d).
[0021]
The disk d has a UTOC (User Table Of Contents) area and a program area. The UTOC area stores UTOC information, which is information for managing music data recorded on the disk d. Music data is written in the program area.
[0022]
The security circuit 11 includes a USB interface for performing communication with the personal computer 3 via the USB cable C, and is transmitted and received between the digital signal processing circuit 12 and the system controller 20 and the personal computer 3. Relay the data.
For example, the security circuit 11 extracts control data transmitted from the personal computer 3 by control transfer, and transmits the control data to the system controller 20. Conversely, the control data transmitted from the system controller 20 is transmitted to the personal computer 3.
The security circuit 11 extracts and decrypts music data (encrypted ATRAC3 data, PCM data, and the like) transmitted from the personal computer 3 by bulk transfer. Then, the decoded music data is transmitted to the digital signal processing circuit 12.
[0023]
The digital signal processing circuit 12 operates as an ADIP (AD dress in pre-groove) decoder, an EFM (Eight to Fourteen Modulation) decoder, a shock-proof memory controller, an ATRAC (Adaptive TRansform Acoustic Coding) encoder / decoder, and a servo control unit. I do.
Specifically, the digital signal processing circuit 12 is controlled by the system controller 20 and the like, and controls the spindle motor 15, the optical pickup 16, the feed motor 17, the head driver 13, and the like.
For example, at the time of checkout, the digital signal processing circuit 12 acquires music data transferred from the personal computer 3 via the security circuit (USB interface) 11 and temporarily stores the music data in the buffer memory 19. Then, the music data stored in the buffer memory 19 is recorded on the disk d by controlling the head driver 13 and the like.
[0024]
The head driver 13 controls the recording head 14 to write music data in the program area of the disk d. Further, the head driver 13 writes UTOC information in the UTOC area.
[0025]
The spindle motor 15 rotates a turntable (not shown) on which the disk d is mounted.
When reproducing the music data, the optical pickup 16 irradiates a laser beam of a predetermined wavelength toward the recording surface of the disk d, receives the reflected light, and converts it into an electric signal. Then, the converted electric signal is supplied to the RF amplifier 18.
When recording music data, the optical pickup 16 irradiates a laser beam toward the recording surface of the disk d and heats it until the temperature becomes equal to or higher than the Curie point.
The feed motor 17 is controlled by the digital signal processing circuit 12 to move the optical pickup 16 to a predetermined position on the disk d.
[0026]
The RF amplifier 18 generates an RF signal, a focus error signal, a tracking error signal, and the like from the electric signal supplied from the optical pickup 16. The RF amplifier 18 supplies the generated RF signal and the like to the digital signal processing circuit 12 and the like.
Further, the RF amplifier 18 extracts groove information (absolute position information recorded as a pre-groove on the magneto-optical disk = ADIP) and the like.
The buffer memory 19 temporarily stores music data of a predetermined capacity at the time of checkout, reproduction, and the like.
[0027]
The system controller 20 includes a one-chip microcomputer and controls the digital signal processing circuit 12 and the like.
Specifically, the system controller 20 instructs the digital signal processing circuit 12 to perform an address search for the disk d, to control the optical pickup 16, and to start ATRAC decoding. Further, it acquires ADIP address information, EFM address information, a write pointer for ATRAC data in the buffer memory 19, a read pointer, and the like.
[0028]
The operation unit 21 includes, for example, a group of a plurality of key switches, and supplies instruction information according to a user operation (such as pressing) to the system controller 20.
The display panel 22 includes a liquid crystal display panel or the like, and displays characters, graphics, and the like indicating the operation status of the recording / reproducing apparatus 1 according to display data supplied from the system controller 20.
[0029]
On the other hand, the personal computer 3 includes an arithmetic unit such as a CPU, storage elements such as a memory and a hard disk, operation devices such as a mouse and a keyboard, display devices such as a display, and a general-purpose personal computer having a USB interface and the like. Note that the personal computer 3 is detachably connected to the recording / reproducing apparatus 1 via a USB cable C.
The personal computer 3 operates according to an OS (Operating System) installed on a hard disk or the like, and executes application software compliant with the NetMD standard on the OS.
[0030]
Specifically, the personal computer 3 stores a management table as shown in FIGS. 2A and 2B in the hard disk, and manages the disk d and the music data.
The disk management table 31 shown in FIG. 2A is a management table for managing a plurality of disks d, and includes, for example, information such as a disk ID, a disk title, the number of tracks, and a recording time. I have.
[0031]
The disk ID is unique identification information for identifying each disk d. The disc title is the same information as the disc title registered for each disc d. In the figure, the disc titles indicated by “DISC — 001” and “DISC — 002” are those automatically generated by the personal computer 3 for a blank disc or a disc d in which no disc title is registered.
Further, the number of tracks indicates the number of pieces of music data recorded on each disk d, and the recording time indicates the total time of all pieces of music data recorded on each disk d.
[0032]
The music management table 32 shown in FIG. 2B is a management table for managing music data stored in the personal computer 3, and includes, for example, a music ID, a music name, a playing time, a remaining check-out number, And information such as a checkout destination. In addition, information such as a file name and a storage folder of music data in the personal computer 3 and information such as a content hash acquired from the recording / reproducing apparatus 1 at the time of checkout are also included.
[0033]
The song ID is unique identification information for identifying each song data.
The music name is a name given to each music data. The performance time is a reproduction time of each music data.
Further, the number of remaining checkouts indicates the current number of remaining pieces of music data for which the limited number of checkouts (for example, three as an initial value) is specified. The check-out destination indicates the ID of the disk that performed the check-out.
That is, the music management table 32 manages the presence / absence (remaining number of times, etc.) of each piece of music data and associates the checked-out music data with the checkout destination disk d.
[0034]
The personal computer 3 that stores the management tables shown in FIGS. 2A and 2B executes a check-out process described later to transfer the music data (contents) stored in the hard disk in advance to the recording / reproducing apparatus 1. Transfer and record on disk d. In addition, a check-in process described later is executed to receive the checked-out music data (actually, a content hash) from the recording / reproducing device 1 and cause the recording / reproducing device 1 to delete the music data.
At that time, the personal computer 3 updates the management tables shown in FIGS. 2A and 2B as appropriate.
[0035]
Hereinafter, the operation of the recording / reproducing system according to the embodiment of the present invention will be described with reference to the drawings.
[0036]
First, the manner in which music data is checked out from the personal computer 3 to the recording / reproducing apparatus 1 will be described with reference to FIG. FIG. 3 is a flowchart for explaining a checkout process executed by the personal computer 3 and a recording process executed by the recording / reproducing apparatus 1.
Each process shown in FIG. 3 is started after music data to be checked out is selected on the personal computer 3 in a state where the recording / reproducing apparatus 1 and the personal computer 3 are connected by the USB cable C. For example, as shown in FIG. 4A, a music list is displayed on a display of a personal computer or the like, and is started after one or more music data is selected by a user and check-out is instructed. It is also assumed that the recording / reproducing apparatus 1 is loaded with a recordable disc d.
[0037]
First, the personal computer 3 receives the disc information from the connected recording / reproducing apparatus 1, and searches the disc management table 31 (step S11). For example, when receiving the disc information including the disc title, the number of tracks, the recording time, and the like from the recording / reproducing apparatus 1, the personal computer 3 checks whether the disc information is included in the disc management table 31 shown in FIG. Please search.
[0038]
The personal computer 3 determines whether or not the disk information is in an unmanaged state by searching (step S12). When the disc information received from the recording / reproducing apparatus 1 is not included in the disc management table 31, the personal computer 3 determines that the disc is in an unmanaged state.
[0039]
If the personal computer 3 determines that the disk information is not in an unmanaged state (it is included in the disk management table 31), the process proceeds to step S16 described below.
On the other hand, if it is determined that the disk is in an unmanaged state, the personal computer 3 determines whether or not a disk title is set in the disk information (step S13).
[0040]
When the personal computer 3 determines that the disc title is set in the disc information, the process proceeds to step S15 described later.
On the other hand, if it is determined that the disc title has not been set, the personal computer 3 automatically generates a disc title (step S14). For example, the personal computer 3 generates a unique disc title “DISC_nnn” (nnn is a serial number).
[0041]
Then, the personal computer 3 adds the disk information to the disk management table 31 (Step S15). At this time, the personal computer 3 generates and adds a unique disk ID for identifying the disk d.
[0042]
The personal computer 3 transmits the target music data to the recording / reproducing device 1 (step S16). That is, the personal computer 3 reads out the music data designated by the user from the hard disk and transfers the music data to the recording / reproducing apparatus 1 via the USB cable C.
[0043]
On the other hand, the recording / reproducing apparatus 1 waits for reception of the music data (step S21). When the music data is received, the received music data is written to the disk d (step S22).
The recording / reproducing device 1 generates hash data and transmits it to the personal computer 3 (Step S23). That is, the recording / reproducing apparatus 1 generates hash data from the music data and the like written on the disk d and transmits the hash data to the personal computer 3 via the USB cable C.
Then, the recording / reproducing apparatus 1 waits until the updated disc information is requested from the personal computer 3 (step S24).
[0044]
Upon receiving the hash data from the recording / reproducing device 1, the personal computer 3 updates the music management table 32 (Step S17).
For example, as shown in FIG. 4B, the personal computer 3 subtracts 1 from the number of remaining check-outs of the checked-out music data, and sets the check-out destination to the disk ID of the disk d (disk management table). 31) is set. The personal computer 3 also sets the received hash data in the music management table 32.
[0045]
Returning to FIG. 3, the personal computer 3 requests the updated disc information from the recording / reproducing apparatus 1 (step S18). That is, the recording / reproducing apparatus 1 requests the recording / reproducing apparatus 1 to transmit the updated disk information because the disk information has changed by recording new music data.
[0046]
On the other hand, when determining that there is a request for disk information, the recording / reproducing apparatus 1 reads out the current disk information and transmits it to the personal computer 3 (step S25).
[0047]
Then, the personal computer 3 receives the disk information sent from the recording / reproducing device 1, and updates the disk management table 31 (step S19).
For example, as shown in FIG. 4C, the personal computer 3 updates the disc management table 31 with the updated disc information whose track number and recording time have changed.
[0048]
As described above, the music data is checked out by the above-described check-out processing and recording processing, and the disk management table 31 and the music management table 32 of the personal computer 3 are updated. In the music management table 32, the checked-out music data is associated with the check-out destination disk d.
[0049]
Next, the manner in which music data is checked in from the recording / reproducing apparatus 1 to the personal computer 3 will be described with reference to FIG. FIG. 5 is a flowchart for explaining a check-in process executed by the personal computer 3 and an erasing process executed by the recording / reproducing apparatus 1.
Each process shown in FIG. 5 is started in a state where the recording / reproducing device 1 and the personal computer 3 are connected by the USB cable C.
[0050]
First, the personal computer 3 reads the music management table 32 and generates a music list (step S31).
For example, as shown in FIG. 6A, the personal computer 3 generates a music list including the music name and the number of remaining checkouts, and displays the generated music list on a display or the like.
[0051]
The personal computer 3 waits until the detailed display is instructed (step S32). When the detailed display is instructed by the user's mouse operation or the like, the personal computer 3 searches the disk management table 31 and displays the disk information (step S33). .
For example, as shown in FIG. 6B, the disk information of the checkout destination of the music data is displayed.
Then, it waits until the disk information and the like sent from the recording / reproducing apparatus 1 are received (step S34).
[0052]
On the other hand, the recording / reproducing apparatus 1 waits until the disk d is inserted (step S51), and when the disk d is inserted, reads out the disk information and transmits it to the personal computer 3 (step S52).
Subsequently, the recording / reproducing apparatus 1 reads out the music management information and transmits it to the personal computer 3 (Step S53). For example, the recording / reproducing apparatus 1 reads out the music management information including the music name, the performance time, and the like from the disc d and transmits the music management information to the personal computer 3.
Then, the recording / reproducing apparatus 1 waits until a check-in is instructed from the personal computer 3 (step S54).
[0053]
When the disc information or the like sent from the recording / reproducing apparatus 1 is sent, the personal computer 3 receives the disc information and searches the disc management table 31 (step S35).
Subsequently, the personal computer 3 receives the music management information sent from the recording / reproducing apparatus 1, and generates a music list recorded on the disk d (step S36).
For example, the personal computer 3 generates a music list as shown in FIG. 7A and displays it on a display or the like.
[0054]
The personal computer 3 waits until a song is selected (step S37). For example, the user waits until one or more check-in items shown in FIG. 7A are marked by a mouse operation by the user and a button or the like for instructing check-in is clicked.
When the music data to be checked in is selected, the personal computer 3 instructs the recording / reproducing apparatus 1 to check in the music data (step S38).
[0055]
On the other hand, when the check-in is instructed, the recording / reproducing apparatus 1 generates hash data and transmits it to the personal computer 3 (step S55). In other words, the recording / reproducing apparatus 1 generates hash data from music data (instructed music data) recorded on the disk d and transmits the hash data to the personal computer 3.
Then, the recording and regenerating device 1 deletes the music data according to the instruction from the personal computer 3 (step S56).
Thereafter, the recording / reproducing apparatus 1 waits until the updated disc information is requested from the personal computer 3 (Step S57).
[0056]
Upon receiving the hash data from the recording / reproducing device 1, the personal computer 3 updates the music management table 32 (Step S39).
For example, as shown in FIG. 7B, the personal computer 3 adds 1 to the number of remaining checkouts of the checked-in music data, and deletes the target disk ID from the checkout destination. Note that the personal computer 3 also deletes the hash data managed in the music management table 32.
[0057]
Returning to FIG. 5, the personal computer 3 requests the updated disc information from the recording / reproducing apparatus 1 (step S40). That is, since the disk information is changed by erasing the music data in the recording / reproducing apparatus 1, the recording / reproducing apparatus 1 is requested to transmit the updated disk information.
[0058]
On the other hand, when determining that there is a request for disk information, the recording / reproducing apparatus 1 reads the current disk information and transmits it to the personal computer 3 (step S58).
[0059]
Then, the personal computer 3 receives the disc information sent from the recording / reproducing apparatus 1, and updates the disc management table 31 (step S41).
For example, as shown in FIG. 7C, the disc management table 31 is updated with the contents of the updated disc information in which the number of tracks and the recording time have changed.
[0060]
As described above, the check-in process and the erasing process allow the music data to be easily checked in. In other words, a list of checked-out songs and disk information of the checked-out destination as shown in FIGS. 6A and 6B are displayed on the display of the personal computer 3. Therefore, the user can easily find the check-out destination disk d.
Then, with the check-in, the disk management table 31 and the music management table 32 are appropriately updated.
[0061]
As a result, in the above-described recording / reproducing system, it is possible to appropriately manage each disk d on which music data is recorded.
[0062]
In the above-described embodiment, the personal computer 3 and the recording / reproducing apparatus 1 compatible with the NetMD standard have been described as an example, and the case where music data is recorded on a disc d composed of an MD has been described. Is not limited to the MD and is optional.
For example, music data may be recorded on a recording medium such as an MO (Magneto-Optical disk) and a DVD-RAM (Digital Versatile Disk-RAM), and a smart media (registered trademark), a memory stick (registered trademark) ) May be recorded on a recording medium such as
Further, the data recorded on the recording medium is not limited to music data, but may be video data or the like.
[0063]
In the above embodiment, the recording / reproducing apparatus 1 and the personal computer 3 each have a USB interface, and the recording / reproducing system in which the recording / reproducing apparatus 1 and the personal computer 3 are connected via the USB cable C will be described. did. However, the interface provided in the recording / reproducing device 1 and the personal computer 3 is not limited to USB, but is optional. For example, an interface such as IEEE 1394 may be used, and the recording / reproducing apparatus 1 and the personal computer 3 may be connected via an IEEE 1394 cable.
[0064]
