Abstract

PROBLEM TO BE SOLVED: To provide a recording and reproducing device which prevents that reproducing and digital output are performed without restriction after a ripping and can be used conveniently by a user. SOLUTION: A hard disk 20 records a series of music data reproduced from a CD 2 and intrinsic information relative to the music data. When the user instructs a reproducing of the music data recorded in the hard disk 20, a CPU of a microcomputer section 10 randomly displays request messages indicating an original CD 2 is to be set. When the CD 2 is set in accordance with the messages, the CPU compares the intrinsic information of the music data included in the CD 2 and the intrinsic information that is already recorded on the hard disk 20 and determines whether agreed intrinsic information exists or not. When agreed intrinsic information exists, the CPU allows the reproducing of the music data instructed by the user.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an audio device or a computer device provided with a recording medium such as a hard disk.

[0002]

2. Description of the Related Art For example, a personal computer is capable of so-called ripping, in which music data obtained from a CD is recorded on a hard disk in the computer. The music data recorded on the hard disk can be reproduced semi-permanently without being deteriorated by digital recording.

In addition, a personal computer is capable of digital output as well as ripping.
With digital output, the music data recorded on a CD can be recorded on a hard disk and transferred from this hard disk to a digital recording device or the like connected to a computer for duplication, but prior to duplication of the music data, , Bit data indicating the copyright management information is output. According to this bit data, duplication of music data is permitted or not permitted. Normally, however, digital output from a personal computer is set to output bit data indicating permission for duplication. There are many.

[0004]

However, if the above-mentioned ripping is used, for example, even if a CD is borrowed in a short term at a rental CD store, the music data of the CD is recorded on the hard disk, and after the CD is returned. Since it can be reproduced semi-permanently, it is disadvantageous from the copyright holder's point of view, and a technical countermeasure against it has been demanded.

According to the above digital output,
Even if the music data of the original CD is once recorded on the hard disk, the music data can be duplicated from the hard disk to MDs, CD-Rs, etc. as many times as necessary without the original CD. Also required effective measures to protect copyright.

Of course, in the digital output, if the bit data for which copying is not permitted is always output, it is possible to surely prevent the illegal copy ignoring the copyright. Even the music data created above cannot be duplicated by digital output, which is very inconvenient for the user.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a block diagram showing the basic structure of a CD audio apparatus equipped with a recording / reproducing apparatus according to the present invention. As shown in this figure, the CD audio device 1 is
A CD mechanism unit 11, an RF signal processing servo amplifier 12, a digital signal processing unit 13, and a microcomputer (hereinafter, abbreviated as “microcomputer unit”) 10 as a control center.
The output unit 14, the hard disk 20, the operation unit 30, the display unit 40, and the like are included in the overall configuration. The microcomputer unit 10 includes an RF signal processing servo amplifier 12, a digital signal processing unit 13, a hard disk 20, an operation unit 30,
And the display unit 40 is connected. In addition, CD2,
An original recording medium in which music data that can be reproduced by the CD audio device 1 is recorded, and in the program area, a series of music data is recorded for each music with a frame as a minimum unit, and a lead-in section In, the reproduction time as unique information of each track (song) is written in units of minutes, seconds, and frames.

The microcomputer unit 10 includes a CPU, R (not shown).
The OM, the RAM, the interface, and the like are integrated, and the CPU controls the overall operation of the CD audio device 1 based on a computer program stored in the ROM. In the control operation, in addition to the operation of simply reproducing the music data, the music data of the CD 2 is recorded on the hard disk 20 while being reproduced (ripping), or the music data of the CD 2 is recorded on the hard disk 20, and is illustrated from the hard disk 20. Do not include operations such as transferring to an external digital recording device for duplication.

The CD mechanism section 11 includes a spindle motor, a sled motor, etc. (not shown), a focus coil for moving the lens up and down with respect to the recording surface of the CD 2, and a tracking coil for moving the lens left and right.
The music data and unique information are read from and the pickup signal is output.

The RF signal processing servo amplifier 12 drives a focus coil, a tracking coil, a sled motor, etc. in response to a pickup signal from the CD mechanism section 11, and drives a spindle motor in response to a signal from the digital signal processing section 13. To drive. Further, the RF signal processing servo amplifier 12 puts the pickup signal on a high frequency and outputs it to the digital signal processing section 13, while transmitting seek information based on the pickup signal to the microcomputer section 10.

The digital signal processing unit 13 binarizes the pickup signal from the RF signal processing servo amplifier 12 to convert it into an EFM (Eight to Fourteen Modulation) signal, and extracts a PLL (Phase-Locked Loop) clock, According to the clock, the EFM signal is demodulated into a bit string and the music data as digital signals and unique information are transmitted to the microcomputer unit 10 and the output unit 14. The digital signal processing unit 13 also performs EFM demodulation, frame extraction, and error correction on the internally generated bit string and the bit string sent from the microcomputer unit 10 as music data, and then outputs a PCM (Pulse-Code Modulation) signal. It outputs to 14.

The output unit 14 converts the PCM signal from the digital signal processing unit 13 into an analog signal via a DA converter (not shown) and supplies the analog signal to a speaker (not shown) to reproduce the music data. Sound is generated as a sound from a speaker. this,
This is called "audio output". The output unit 14 also externally connects the music data and unique information as a digital signal sent from the microcomputer unit 10 via the digital signal processing unit 13 to a digital signal such as an MD or a CD-R not shown. Transfer to recording device. In a digital recording device, duplication is performed by recording music data on an MD or CD-R as a secondary recording medium. this,
Called "digital output".

The hard disk 20 records the music data of the CD 2 and unique information for each music under the access control of the microcomputer unit 10. Of course, the music data and unique information recorded on the hard disk 20 can be read for each music by the access control of the microcomputer unit 10 at the time of audio output or digital output. Although not particularly shown, the hard disk 20 also records the number of times of reproduction, which indicates the cumulative number of times of reproduction for each song, in association with the unique information.

The operation section 30 is provided with various operation keys and transmits a signal according to a user's key operation to the microcomputer section 10. In particular, the operation unit 30 is provided with operation keys for instructing reproduction of music data associated with audio output or digital output. The display unit 40 displays a song number, song time, etc. under the control of the microcomputer unit 10 that reads out unique information when reproducing the song data.

Next, the reproducing process of the music data will be described with reference to the drawings.

FIG. 2 is a flow chart showing a reproducing process of music data in the CD audio apparatus 1. In the figure, “N” is the number of reproductions accumulated and recorded at the time when the user instructs reproduction, “Nmax” is the maximum number of reproductions defined in advance in the program as an upper limit, and “Nr” is , An arbitrary integer given randomly according to a certain condition.

As shown in FIG. 2, first, when the user gives an instruction to reproduce the music data recorded in the hard disk 20, the CPU of the microcomputer unit 10
Determines whether or not the specific information corresponding to the music data for which reproduction is instructed is recorded in the hard disk 20 (S1). Such unique information is recorded in advance at the time of ripping or digital output. When recording the unique information, the number of times of reproduction “N” is also recorded, but the number of times of reproduction “N” is set to “0” at the time of the first recording.
It should be noted that some of the music data recorded on the hard disk 20 may be saved after being created by the user himself.
With respect to the music data created by the user himself / herself, the unique information is not recorded in the hard disk 20 in the first place.

When the corresponding unique information has been recorded (S
1: YES), the CPU is the number of times of reproduction “N” at this point.
Is determined to be less than the maximum number of times of reproduction "Nmax" (S2).

The number of reproductions "N" is the maximum number of reproductions "Nmax"
If smaller (S2: YES), the CPU determines one numerical value "Nr" within the range from the number of reproductions "N" to the maximum number of reproductions "Nmax" by the random sampling method (S3).

Further, the CPU determines whether or not the random numerical value "Nr" determined in S3 matches the current number of times of reproduction "N" (S4).

When the numerical value "Nr" matches the number of times of reproduction "N" (S4: YES), the CPU indicates that the original CD2, which is the source of the music data instructed to be reproduced, is set in the CD mechanism section 11. The request message is randomly displayed (S5). Of course, such a request message may be transmitted by voice.

Thereafter, the CPU determines whether or not the CD2 is set in the CD mechanism section 11 by the user in response to the request message (S6).

When the CD 2 is set in the CD mechanism section 11 (S6: YES), the CPU reads the unique information from the lead-in section of the CD 2 (S7).

Then, the CPU determines whether or not the unique information read from the CD 2 matches the unique information of the music data for which reproduction is instructed in all of the minutes, seconds, and frames (S8). ). That is, by using the reproduction time including not only the minutes and seconds but also the frame as the unique information as a criterion, whether or not the set CD2 is the original including the music data for which reproduction is instructed is extremely strictly discriminated.

When the unique information read from the CD 2 and the unique information of the music data for which reproduction is instructed match (S8:
YES), the CPU determines that the original CD 2 has been set, updates the number of times of reproduction “N” regarding the music data for which the reproduction instruction is given to “0”, and updates the hard disk 20.
(S9).

After that, the CPU reads the music data instructed to be reproduced from the hard disk 20, reproduces the music data, and finishes the reproduction processing (S10). The reproduction of the music data here means audio output or digital output. In other words, assuming that the original CD 2 is on hand, even if the music data is recorded on the hard disk 20 by ripping, the playback sound based on the music data can be heard, and the music data can be recorded on an externally connected digital recording device. Can be transferred and dubbed onto a secondary recording medium such as MD or CD-R. here,
When digital output (dubbing) is performed under the condition that the unique information matches, bit data serving as copyright management information indicating permission for copying is output to the digital recording device. There are two types of bit data indicating duplication permission, one that allows dubbing of only one generation and the other that allows dubbing over several generations. Here, bit data corresponding to dubbing of only one generation is output. The music data for which reproduction is instructed is the original CD2.
It is also possible to read from and reproduce.

If the unique information read from the CD 2 does not match the unique information of the music data instructed to be reproduced in S8 (S8: NO), the CPU determines that the original CD
If it is not 2, the request message similar to S5 is displayed again (S11). After that, the CPU returns to S6. Here, under the condition that the unique information does not match,
Bit data indicating that copying is not permitted is output to a digital recording device and cannot be dubbed on a secondary recording medium such as MD or CD-R. If the unique information does not match even after the routine up to S11 is executed a prescribed number of times, the process may proceed to S13, which will be described later.

If the CD 2 is not set in the CD mechanism section 11 in S6 (S6: NO), the CPU determines whether or not the reproduction instruction is canceled by the user (S12).

When the reproduction instruction is canceled by the user (S12: YES), the CPU changes the number of times of reproduction "N" relating to the music data for which the reproduction instruction is received to a value of "Nmax" or more and records it in the hard disk 20. (S13),
The reproduction process ends without reproducing the music data. In this case, it is recognized that the original CD2 is not at hand, and the music data recorded on the hard disk 20 cannot be reproduced unless the original CD2 is set. In the case of digital output, instead of changing the value of the number of times of reproduction “N”, the bit data may be output as the copy not permitted.

In S12, if the reproduction instruction is not canceled by the user (S12: NO),
The CPU returns to S6 and waits. If the CD 2 is not set in the CD mechanism unit 11 even after a certain period of time, the process may be forced to proceed to S13.

In S4, when the randomly determined numerical value "Nr" does not match the number of times of reproduction "N" (S4: N
O), the CPU adds 1 to the number of times of reproduction “N” of the music data for which the reproduction instruction is received to make it “N + 1” (S14),
Proceed to S10. In this case, the original CD 2 is not required, and even if the original CD 2 is not at hand, the music data instructed to be reproduced can be read from the hard disk 20 and reproduced. According to the theory of probability, the random number “Nr” has a higher probability that the random number “Nr” matches the number “N” of reproductions as the number “N” of reproductions is closer to the maximum number “Nmax” of reproductions. When the number of times "N" is "0", the probability of matching is lowest. That is, as the number of times of reproduction “N” increases, a request message for setting the original CD 2 is likely to appear, and the user can be effectively warned.

When the number of reproductions "N" is equal to or larger than the maximum number of reproductions "Nmax" in S2 (S2: NO), the CPU
Proceed to S5. In this case, the original CD 2 is always required because the music data for which reproduction is instructed has already been reproduced for the maximum number of times of reproduction “Nmax” which is the upper limit.

In S1, if the unique information of the music data instructed to be reproduced is not recorded in the hard disk 20 (S1: NO), the CPU proceeds directly to S10.
In this case, not the music data by ripping,
It is determined that the music data is created by the user himself and stored in the hard disk 20, and such music data can be read from the hard disk 20 and reproduced without any problem. Here, in the case of digital output in particular, bit data indicating duplication permission is output to the digital recording device over generations, and M
It can be dubbed on a secondary recording medium such as D or CD-R any number of times.

Therefore, according to the above-described embodiment, even if the music data is recorded on the hard disk 20 by ripping or the like, the original CD 2 from which the music data is derived is recorded.
If you don't have the CD, and if the original CD2 is requested indiscriminately, you cannot output audio or digital output.
It is possible to prevent the audio output and the digital output in the situation where there is no 2 from being unlimitedly performed. On the other hand, a user who owns the original CD 2 can use the ripping and digital output without any trouble.

Next, another embodiment will be briefly described.

As another embodiment, as shown in FIG. 3, for example, a CD changer 1 capable of inserting several hundreds of CDs and reading music data and unique information from each CD.
In contrast to A, a system configuration may be adopted in which a HDD audio player 1B that incorporates a hard disk 1C and plays back music data is connected by a signal line 1D. In this case, the CD audio device 1 according to the above-described embodiment is configured so as to be separated, and specifically, the CD changer 1A includes a microcomputer for controlling the entire operation and the above-described CD.
The mechanical unit 11, the RF signal processing servo amplifier 12, and the like are mounted. On the other hand, in the HDD audio player 1B,
In addition to a microcomputer that controls the overall operation, an output unit 1 including a digital signal processing unit 13 and a speaker 15
4, and further the operation unit 30 and the display unit 40 are mounted. C
In the D changer 1A, when the inserted CDs are played back or when idling is rotated, unique information can be read from these CDs and stored in a nonvolatile memory or the like included in the microcomputer.

With respect to the music data recorded on the hard disk 1C by ripping, the HDD audio player 1B can perform audio output or digital output. At this time, the same reproduction process as that of the above-described embodiment is performed, but if the randomly given numerical value "Nr" matches the current number of reproductions "N", the HDD audio player 1B reads the CD changer. 1A is requested to transfer the unique information. CD accordingly
When the unique information acquired for each CD from the changer 1A is transferred, the HDD audio player 1B checks whether or not the matching unique information exists. Other processes are the same as those in the above-described embodiment.

Therefore, the same effects as those of the above-described embodiment can be obtained by the other embodiments. In particular,
According to another embodiment, since a large number of CDs can be inserted in advance, the reproduction process can be performed by omitting the steps S5 to S7 shown in FIG. 2, and the original CD is already inserted. If the user has a CD
Original CD by the user without the need to set
It can reduce the burden of replacing. Note that in other embodiments, the steps of S12 and S13 shown in FIG. 2 may be executed subsequent to S11.

Furthermore, as a modified example of another embodiment,
As shown in FIG. 4, the HDD audio player 1B has a system configuration in which audio devices 3A and 4A as clients are connected via a network cable 1E,
The speakers 3 of the client audio devices 3A and 4A are digitally output from the HDD audio player 1B.
A reproduced sound based on the music data may be generated from B and 4B. With such a configuration, the CD changer 1
The playback sound can be heard by the client audio devices 3A and 4A at a remote place apart from the installation location of the A or HDD audio playback device 1B.

Therefore, even with such a modification, the same effects as those of the other embodiments described above can be obtained. In particular, according to the modified example, by inserting a large number of CDs including the original CD into the CD changer 1A in advance, even when the original CD is required, the CD changer 1A or the like can be installed from the place where the reproduced sound is heard. There is no need to go to a different place, and the burden of replacing the original CD by the user can be reduced.

The present invention is not limited to the above embodiments.

In S5 of FIG. 2, the original CD2 is requested randomly according to the number of times of reproduction "N", but the reproduction time of the music data is stored in the hard disk 20 or the like every time the music data is reproduced. Alternatively, the CPU of the microcomputer unit 10 may obtain the elapsed time from the previous reproduction time until receiving the current reproduction instruction, and may request the original CD 2 when the elapsed time is equal to or longer than a predetermined time.

Although the original CD2 is requested under the stochastic control, the original CD2 may be always requested after a fixed number of times of reproduction and a fixed time after the recording date and time.

As the primary recording medium as the first recording medium, in addition to a portable CD, for example, a DVD or M
It may be D, CD-R or the like. As the second recording medium for recording the music data by ripping, etc.,
Besides hard disk, for example, semiconductor memory and CD
It may be -R or the like. A secondary recording medium as a third recording medium capable of duplicating music data is MD or C.
In addition to the D-R, for example, a hard disk or a memory card built in a personal computer or the like may be used.

Music data having a relatively large data size is recorded in the hard disk, but unique information having a relatively small data size is stored in a non-volatile memory as a unique information storage unit included in the microcomputer section 10. It may be done.

In the above embodiment, there are two types of copyright management information indicating permission of copying: bit data that allows dubbing of only one generation and bit data that allows dubbing for many generations. These bit data may have the same content, for example, may indicate duplication permission without limitation on the number of times of dubbing.

The present invention can be applied not only to the CD audio device 1 and the like, but also to a personal computer or the like used for general purposes.
