- the control unit 3110 controls the recording control unit 311 in step S 5 17 to enable the copy recording. You.
- step S 518 the compressed audio data from the selector 304 is subjected to scramble processing (encryption processing) in the scramble section 313 through the recording control section 331, and the step S 519 In, the data is written to the semiconductor memory 40 via the writing section 3 13 and the media interface 3 14.
- step S520 the ISRC and the track number, which are the identification signals of the information to be copied and extracted as the decoded output of the digital watermark information, are stored in the recording control unit 311, scramble unit 312, and writing unit.
- the data is sent to the semiconductor memory 40 via the interface 3 13 and the media interface 3 14 and written into the copy history information memory section 45.
- the charging flag in the information supplied from the controller unit 310 to the semiconductor memory 40 is set, so that in step S521, the duplication fee is stored from the duplication balance storage unit 47.
- the withdrawal process is performed by the charge calculation unit 46.
- the copy control process for the input information from the input terminal 301 ends.
- the SCMS-based copy control information is extracted from the decryption unit 303 and is used as a “one-time copy allowed”.
- the recording control unit 311 rewrites the SCMS type copy control information added to the recorded audio data to the state of “copy prohibited”.
- step S504 the duplication in the case where it is determined that the duplication target is the analog audio signal input through the input terminal 310 is described with reference to the flowchart shown in FIG. explain.
- the reproduction control device 100 superimposes the copy control information and the identification signal as the digital watermark information WM on the analog audio signal.
- the digital watermark information WM is detected by the digital watermark information decoding unit 309 and supplied to the control unit 310.
- the control unit 3110 determines whether recording (duplication) of the input information is possible based on the determination output of the digital watermark information WM. If it is determined that the recording is prohibited, in step S523, the recording control unit 311 and the writing unit 3113 are controlled so that the recording to the semiconductor memory 40 is not executed.
- step S524 If the control unit 310 determines from the digital watermark information WM that recording (copying) is possible, in step S524, it is possible to perform one-time copying that requires rewriting the copy control information (Copy Once). ) Is determined. If it is determined by the digital watermark information WM that copying is permitted (Copy Free), in step S525, the recording control unit 311 and the writing unit 3113 are controlled to enable recording. In step S526, the compressed audio data from the compression encoder unit 308 is supplied to the recording control unit 311 through the selector 304, and the scramble unit 3112 performs scramble processing (encryption). place Then, in step S 527, the data is written to the semiconductor memory 40 via the writing section 313 and the media interface 314. In this case, since the copy of the input data is permitted (Copy Free), the SCMS information added to the compressed digital video data output from the recording control unit 311 is not rewritten. The identification signal is not recorded in the copy history information memory 320.
- step S524 when it is determined by the digital watermark information WM that copying can be performed once (Copy Once), in step S528, the identification signal is extracted, and the copy history information memory 320 is copied. With reference to the stored information, it is determined whether or not the audio data of the identification signal has already been copied and recorded.
- control unit 3110 determines in step S529 that the duplication recording is permitted. At the same time, the recording control section 311 rewrites the SCMS information to “recording prohibited”.
- step S530 the scramble processing (encoding processing) is performed in the scramble unit 3112.
- step S5301 the writing unit is processed.
- the audio data is written to the semiconductor memory 40 via the 3 13 and the media interface 3 14, and in step S 5 32, the identification signal of the audio data is stored in the copy history information memory section 3 20. Is written.
- step S533 it is determined whether or not the charge condition in the semiconductor memory 40 is satisfied in the same manner as described above. If the charging condition is not satisfied, the process proceeds to step S523, and copying is prohibited.
- the control unit 3110 satisfies the charging conditions in step S 5 34, and when it is determined to execute the recording, the recording control unit 311 records the SCMS information in the recording control unit 311. "Prohibited”.
- the processing after the recording control unit 311 is the same as described above.
- step S535 the scramble process (encoding process) is performed in the scramble unit 312, and in step S5336, the write unit is processed.
- the audio data is written to the semiconductor memory 40 via the interface 3 13 and the media interface 3 14.
- step S 537 the recording control unit 311, the scramble unit 312, and the writing unit output the ISRC and track number as identification signals of the information to be copied extracted as the decoded output of the digital watermark information.
- the data is sent to the semiconductor memory 40 through 3 13 and the media interface 3 14, and is written into the copy history information memory section 45.
- the charging flag in the information supplied from the control unit 310 to the semiconductor memory 40 is set, so that in step S550, the duplication fee is calculated from the duplication balance storage unit 47.
- the withdrawal process is performed by the billing calculation unit 46, and the process ends when the billing process is completed.
- the third embodiment in the case of constant-speed copying, replication control by the conventional SCMS method is performed, but in the case of high-speed copying, one recording is performed for the same information signal.
- the first copy can be performed free of charge on the machine 300, but the second and subsequent Since the copy is controlled on condition that the fee is collected, it is possible to prevent the first generation copy from being performed at high speed and without restriction and to surely protect the interests of the copyright holder. .
- the first duplication can be performed free of charge on one recorder, but duplication is permitted on condition that payment of duplication fee from the first duplication You may do it.
- the copying speed is high.
- the billing system is not limited to the case of using a prepaid card system, and a billing authentication system using a telephone line or the like can be used as described above.
- the information signal to be duplicated described in the example of the audio signal may be an image signal. It may be an information signal that is not a time-series signal such as an audio signal or an image signal, for example, a computer data.
- a control signal for controlling another device may be used.
- the information output device is not limited to the above-described reproducing device, but also includes a device that temporarily stores information to be copied in a memory, reads the information from the memory, and outputs the information to a recording device.
