Abstract

PROBLEM TO BE SOLVED: To suitably control a copy operation history of a copyright protection, etc., by protecting the storage area of copy control information set in a memory as necessary and sufficient. SOLUTION: When high speed recording operation is instructed/operated by an operation part 8, copyright information is read out from a CD by a read- out part 2, and the copyright information is fetched to a CPU 3. The CPU 3 discriminates the number of pieces of copyright information stored beforehand in a memory 4, decides propriety of a storage of the copyright information into the memory 4, and further discriminates the propriety of the high speed recording to control a write-in part 5 and a display part 7. The CPU 3 discriminates whether the amount of copyright information stored in the memory 4 has reached the allowable limit when the high speed recording operation is instructed and the CPU 3 stores the copyright information. When the amount of copyright information in the memory 4 reaches the allowable limit, the CPU 3 does not allow the memory 4 to store it and makes a display part 7 to show this situation. When the copyright information cannot be stored, the high speed recording operation is prohibited.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus capable of recording information such as an audio signal on a recording medium, and more particularly to reproducing information including copy management information such as copyright information reproduced from a recording medium. The present invention relates to a recording apparatus capable of performing appropriate duplication management for protection of copyright and the like when recording on a recording medium.

[0002]

2. Description of the Related Art For example, a CD (compact disk) (C
When a digital signal such as video or audio information reproduced from a D-DA (CD digital audio) and a DVD (digital versatile disk) (DVD Audio, DVD Video) or the like is recorded on a recording medium, an analog signal is recorded as an analog signal. It is possible to perform recording and digital recording in which recording is performed using digital signals similar to those of CDs and DVDs. Conventional recording devices generally perform analog recording using a magnetic tape or the like as a recording medium. recent years,
With the development of digital technology, recording devices that enable digital recording on digital recording media have become widespread. As digital recording media, MD (mini-disc to trademark), CD-R (CD recordable), CD-RW
(CD rewritable), DVD-RAM (DVD random access memory), DVD-R, DVD-R / W, D
VD + RW, DAT (digital audio tape),
A solid-state memory (flash memory) or the like is used.

In the conventional analog recording, deterioration of information and reduction of the amount of information due to reproduction / recording of an analog signal are unavoidable. In digital recording, the sampling rate and the number of quantization bits are larger than those of the reproduction information. If the number is small, it is inevitable that the information is deteriorated and the amount of information is reduced due to the recording process, such as once converting to analog and resampling. However, when digital recording is performed at a sufficient sampling rate and a sufficient number of quantization bits equal to or higher than that of the reproduced information, the original recording medium is hardly deteriorated in information and the amount of information is hardly reduced. Media can be duplicated.

[0004] In such a recording apparatus capable of digitally recording on a digital recording medium, copying for the purpose of private use by a user is performed. In such a recording apparatus, for example, a recording apparatus using an MD as a recording medium, a function for simplifying a duplication operation such as a so-called high-speed dubbing (a function of dubbing at a higher speed than a normal recording / reproducing speed) or the like. The fulfillment is remarkable. However, MD
Enhancement of the duplication function in a recording device capable of digital recording, such as, facilitates duplication beyond private use, and does not pose a risk of infringing the copyright of the creator of the original recording medium, such as the duplication right. In. On the other hand, in a recording device capable of digital recording, SCMS (Serial Copy Management
System) and other technologies to prevent unlimited copying from digital sound sources. That is,
In the SCMS, for example, when music data whose copyright is to be protected is recorded on an MD, the first generation copy from an original recording medium such as a CD to the MD is possible. Copy the recorded data of MD to other M
You cannot "copy grandchild" to D. Thus, S
By limiting the number of duplicate generations, CMS puts a stop on replicas beyond private use.

[0005] Recently, regarding copyright protection of digital audio information, recently, SDM has been proposed.
Studies are underway by I (Secure Digital Music Initiative) to standardize a technology corresponding to a technology for compressing and recording digital audio data. Also, M
The MPEG4 standard, which defines the video and audio compression method under development of specifications by the Moving Picture Experts Group (PEG), uses IPMP (Intellectual Property Manageme).
It is said to include an interface with an intellectual property protection system called "nt and Protection".

[0006] In addition, the above-described recording apparatus such as an MD often has a high-speed recording function for high-speed dubbing, which enables copying in a short time for the convenience of the user. Therefore, simply permitting only one generation of copy recording by the above-mentioned SCMS, if the recording device is equipped with a high-speed dubbing function, the permitted one generation of duplication can be repeated many times in a short period of time, and the identification can be performed. Of individuals can make large numbers of copies beyond private use. For this reason, even if the SCMS is adopted, the copyright may be easily infringed if the high-speed recording function is provided.

On the other hand, Japanese Patent Application Laid-Open No. 11-53818 discloses that, for example, when audio information is copied from a CD to an MD, the presence or absence of a copy history, the number of copies, the order of the history of the copy operation, the time interval of the copy operation, and the recording medium There is disclosed a recording apparatus capable of prohibiting duplication and controlling the duplication speed in accordance with an operation history such as the presence or absence of replacement of a printer, and capable of finely setting predetermined conditions to be recognized in operation. In the recording apparatus disclosed in Japanese Patent Application Laid-Open No. H11-53818, it is possible to flexibly limit the number of copies of one generation while flexibly securing the convenience of the user such as re-recording and re-editing in the range of private use. It is possible to suppress a large amount of copying that would infringe copyright.

[0008]

As shown in FIG. 2, the CPU 3 includes a read information processing section 31, a storage capacity check section 32, a capacity over notification section 33, a copyright information confirmation section 34, an ID collation section 35,
Memory access control unit 36, copyright information storage control unit 3
7, and a function as a recording operation control unit 38. These units do not necessarily need to be configured by hardware, and can be realized as processing functions by software.

The read information processing section 31 includes the read section 2
, The information read from the CD is processed, and in this case, copyright information is extracted as copy management information. The storage capacity check unit 32 checks the storage status of the copyright information in the storage area of the memory 4 via the memory access control unit 36,
Whether or not there is an area for storing the copyright information extracted by the read information processing unit 31 is determined by judging the number of already stored copyright information or determining the remaining amount of the storage area and the size of the newly extracted copyright information. It is determined by comparison or the like. If the storage capacity check unit 32 determines that there is no room to store new copyright information in the copyright information storage area of the memory 4, the storage capacity check unit 32 instructs the capacity over notification unit 33 to notify the capacity over notification, and performs recording. The operation controller 38 is instructed to prohibit the high-speed recording operation. If the storage capacity check unit 32 determines that there is room for storing new copyright information in the copyright information storage area, the storage capacity check unit 32 sends the copyright information Instruct collation and ID collation.

When the storage capacity check section 32 instructs the notification of the capacity over, the capacity over notification section 33 causes the display section 7 to display the capacity over by at least one of an alarm sound, a voice display, a character display, and a graphic display. Notify. The copyright information confirmation unit 34 is a storage capacity check unit 32
Will provide you with copyright information and ask you to confirm it,
It is checked whether or not the given information is appropriate copyright information indicating that copying is possible (copying is not prohibited). ID
When ID collation is instructed from the storage capacity check unit 32, the collation unit 35 replaces the copyright information having the ID matching the copyright information confirmed by the copyright information confirmation unit 34 with the copyright information of the memory 4. Whether or not the data is already stored in the storage area is confirmed via the memory access control unit 36. The memory access control unit 36 controls access to the storage area of the copyright information in the memory 4 by the storage capacity check unit 32, the copyright information confirmation unit 34, the ID collation unit 35, and the copyright information storage control unit 37.

The copyright information storage control unit 37 stores an ID matching the copyright information confirmed by the copyright information confirmation unit 34.
Is determined by the ID collating unit 35 that the copyright information having the following has not been stored in the copyright information storage area of the memory 4, the copyright information is transferred via the memory access control unit 36. And the write prohibition information is stored in the copyright information storage area of the memory 4, and the writing section 5 is controlled via the recording operation control section 38 to read out the read section 2.
Thus, information read from the CD is written to the MD by a high-speed recording operation. The recording operation control unit 38 controls the CD operation only when instructed by the copyright information storage control unit 37.
The high-speed recording is performed by the writing unit 5 for the information read out from the memory, and otherwise, the high-speed recording is not performed.

Next, the flow of processing of copyright information in the operation of the CD / MD system shown in FIGS. 1 and 2 will be described with reference to FIG.
This will be described with reference to the flowchart shown in FIG.

By operating the operation unit 8, for example, from a CD to M
When a high-speed recording operation for high-speed dubbing to D is instructed, processing of copyright information as shown in FIG. 3 is started.
When the copyright information processing is started, the CPU 3 causes the storage capacity check unit 32 to read the copyright information extracted from the read / playback signal from the CD and extracted by the information processing unit 31 and store the copyright information in the copyright information storage area of the memory 4. When stored in
It is determined in advance whether the storage area overflows (step S11). When the storage capacity check unit 32 determines that the storage area overflows, the capacity over is notified to the display unit 7 via the capacity over notification unit 33 by an alarm, a voice, a character, a graphic, or the like (step S12). In this case, the storage capacity check unit 32
Prohibits the recording operation control unit 38 from performing the high-speed recording operation (step S13), ends the process, and returns to the steady state.

In step S11, when the storage capacity check unit 32 determines that the storage area does not overflow, the copyright information check unit 32 determines whether or not the copyright information extracted by the read information processing unit 31 is decrypted as copyable. 34 (step S14), and if it is determined that copying is possible, the ID included in the copyright information by the ID collating unit 35 is assigned to all the copyright information already stored in the storage area. It is determined whether or not the ID does not match (step S15). In step S15,
If it is determined that they do not match, the copyright information storage control unit 27 stores the copyright information in the storage area of the memory 4 while prohibiting subsequent recording (step S1).
6) Permit high-speed recording of information read from the corresponding CD to the MD (step S17), cause the writing unit 5 to perform a high-speed writing operation, end the process, and return to the steady state.

In step S14, if the copyright information extracted by the read information processing section 31 is not decrypted as copyable, that is, if the copyright information cannot be decrypted, or if it is decrypted as copy prohibited, the copyright information confirmation is performed. The unit 34 prohibits the recording operation control unit 38 from performing the high-speed recording operation (step S18), ends the process, and returns to the steady state.

Also, in step S15, if the copyright information having the ID matching the ID included in the copyright information is already stored in the storage area, the process proceeds to step S18, and the ID collating unit 35 Prohibits the high-speed recording operation to the recording operation control unit 38, ends the process, and returns to the steady state.

As described above, the copy management information such as the copyright information stored in the memory 4 for protecting the copyright of the CD or the like is likely to exceed the amount secured in the memory 4 on the assumption that it is necessary and sufficient in advance. When it becomes, further storage operation is prohibited, and the fact is notified to the user by audio or visual information, and the accompanying processing is also suppressed.

That is, the CD set in the CD driving section 1
Therefore, when dubbing is performed on the MD set in the MD drive unit 6 by high-speed recording, when the high-speed recording operation for high-speed dubbing is instructed by the operation unit 8, the copyright is read from the CD via the reading unit 2. The information is read, and the copyright information is taken into the CPU 3. The CPU 3 determines, for example, the number of pieces of copyright information already stored in the memory 4, determines whether the copyright information can be stored in the memory 4, and further determines whether the high-speed recording can be performed. , The writing unit 5 and the display unit 7.

When the CPU 3 is instructed to perform a high-speed recording operation,
When storing the copyright information, it is determined whether or not the amount of the copyright information stored in the memory 4 has reached an allowable limit. If the amount of copyright information in the memory 4 has reached the allowable limit, it is not stored in the memory 4 regardless of the content of the copyright information. At this time, information notifying the fact is displayed on the display unit 7. The display indicating that the copyright information cannot be stored may be displayed by characters or by voice. Furthermore, a warning or a graphic display such as a symbol mark may indicate that the copyright information cannot be stored. If the copyright information cannot be stored in this way, since protection of the copyright cannot be guaranteed, high-speed recording operation is prohibited and high-speed dubbing is prevented.

As described above, when the storage area of the copyright information of the memory 4 which is originally set as necessary and sufficient is likely to overflow, further storage is prevented, and the already stored copyright information is protected. As a result, copyright can be properly protected. Also, the user
The notification by the display unit 7 makes it possible to clearly understand that high-speed dubbing is prohibited for the purpose of copyright protection.

In order to protect the copyright, it is considered that the number of copy / write generations may be limited to a predetermined generation (n generations) instead of one generation. Generation management may be performed using copy management information such as information.

(Second Embodiment) FIG. 4 shows a CD / CD adopting a recording system according to a second embodiment of the present invention.
2 shows a functional configuration of a main part of the MD system. In this case, the operation of the operation unit 8 or the like is invalidated in place of the display by voice or characters indicating that high-speed copying cannot be performed. The difference from the configuration shown in FIG. 1 is that, when the storage area of the copyright information in the memory 4 is about to overflow instead of the CPU 3, the operation of the operation unit 8 or the like is not performed by displaying the sound or characters. The point is that the CPU 3A to be invalidated is used. That is, the CPU 3A shown in FIG.
The capacity over notification unit 33 in the CPU 3 of FIG.
Instead of the storage capacity check unit 32 and the recording operation control unit 38, a storage capacity check unit 32A and a recording operation control unit 38A are provided.

Therefore, as shown in FIG. 4, the CPU 3A reads the read information processing section 31, the storage capacity check section 3
2A, a copyright information confirmation unit 34, an ID collation unit 35, a memory access control unit 36, a copyright information storage control unit 37, and a recording operation control unit 38A.

The CPU 3A is also formed using a microprocessor or the like, and achieves various functions in response to the operation of the operation unit 8. When the high-speed dubbing from the CD to the MD, that is, the high-speed recording of the copy is instructed, the CPU 3A reads the recording information of the CD via the reading unit 2, and reads the copy management information, for example, the copyright information, from the read information. Is extracted, and the storage status of the copyright information in the storage area for the copyright information in the memory 4 is checked. If there is no room to newly store the copyright information in the storage area for the copyright information in the memory 4, the copyright is protected. Therefore, the operation relating to the high-speed recording of the operation unit 8 is invalidated and the high-speed recording operation is prohibited.

If there is room to newly store the copyright information in the storage area of the memory 4, the CPU 3 A
The copyright information extracted from the information read from the CD can be decrypted, and further, if the copyright information ID does not match the already stored copyright information ID with reference to the copyright information storage area of the memory 4, The copyright information is stored in the memory 4, the high-speed recording operation is permitted, and the writing unit 5 is instructed to perform the high-speed recording operation. When the copyright information extracted from the information read from the CD indicates that copying should be prohibited, when the copyright information cannot be decrypted, and when the ID matches the ID of the copyright information already stored Has C
Since the PU 3A still cannot protect the copyright, the PU 3A prohibits the high-speed recording operation.

The read information processing section 31 of the CPU 3A
Processing the information read from the CD by the reading unit 2;
In this case, copyright information is extracted as copy management information.
The storage capacity check unit 32A includes the memory access control unit 3
6, the storage status of the copyright information in the storage area of the memory 4 is checked, and whether or not there is an area for storing the copyright information extracted by the read information processing unit 31 is determined by the number of already stored copyright information. Or by comparing the remaining amount of the storage area with the size of the newly extracted copyright information. If the storage capacity check unit 32A determines that there is no room for storing new copyright information in the copyright information storage area of the memory 4, the recording operation control unit 38A sends the high-speed recording operation of the operation unit 8 to the recording operation control unit 38A. Instruction to invalidate the operation for causing the high-speed recording operation to be prohibited. If the storage capacity check unit 32A determines that there is room to store new copyright information in the copyright information storage area, the storage capacity check unit 32A sends the copyright information Instruct collation and ID collation.

The copyright information confirmation unit 34 receives the copyright information from the storage capacity check unit 32A and, when instructed to confirm the copyright information, indicates that the given information indicates that copying is permitted (duplication is not prohibited). Check if the copyright information is correct. When ID collation is instructed from the storage capacity check unit 32A, the ID collation unit 35 converts the copyright information having an ID that matches the copyright information confirmed by the copyright information confirmation unit 34 into the copyright information in the memory 4. It is confirmed via the memory access control unit 36 whether or not the data has already been stored in the storage area of. The memory access control unit 36 includes a storage capacity check unit 32A, a copyright information confirmation unit 34, an ID collation unit 35,
In addition, access to the copyright information storage area of the memory 4 by the copyright information storage control unit 37 is controlled.
