DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a video cassette tape as a whole as a recording medium, and a cassette label 3 having a thickness of about 0.4 [mm] containing a memory IC 2 as a storage means is attached to a spine. The title of the recorded program is written in the cassette label 3 in the same manner as the conventional paper label.

In the cassette label 3, as shown in FIG. 2, a memory IC 2 is mounted on a substrate 8 disposed at the center, and an antenna wiring 4 formed of a coil-like pattern is connected to the memory IC 2. A release paper 10 is attached to the lower surface of the substrate 8 via a pressure-sensitive adhesive 9.

A reinforcing plate 6 made of a PET (polyethylene terephthalate) material is provided on the upper surface side of the substrate 8, and the high quality paper 5 is attached to the reinforcing plate 6. Here, a through hole 7 having a size slightly larger than the memory IC 2 is provided in the reinforcing plate 6 at a position facing the memory IC 2, whereby the memory IC 2 is housed in the through hole 7 and the surface of the reinforcing plate 6 is formed. So that it does not protrude.

The cassette label 3 thus formed is peeled off from the release paper 10 and attached to the spine of the video cassette tape 1 via the pressure-sensitive adhesive 9.
By the way, the memory IC2 of the cassette label 3 has 1024
It has a storage capacity of [byte], records various program information related to the program such as the program title name, recording date and time, recording time, etc., as well as features and characteristics of video scenes for which you want to restrict viewing to a young age group. A classification code as classification information indicating the degree can be recorded.

Subsequently, as shown in FIG. 3, power is supplied to the memory IC 2 of the cassette label 3 from the reader / writer module 13 of the VTR 20 as a recording / reproducing apparatus via the harness 14 and the connector 15 to the antenna of the reader / writer antenna board 11. By passing a current through the pattern 12, a magnetic field 16 is generated around the antenna pattern 12, and the magnetic field 16 is applied to the antenna wiring 4 of the cassette label 3 to generate an induced electromotive force in the antenna wiring 4. Activate the memory IC2.

The reader / writer module 13 of the VTR 20 changes the magnetic field by changing the amount of current flowing through the antenna pattern 12 of the reader / writer antenna board 11, and applies the fluctuating magnetic field to the antenna wiring 4 of the cassette label 3. The induced electromotive force is changed, and the voltage change is written as data to the memory IC2.

The cassette label 3 changes the amount of current flowing through the antenna wiring 4 in accordance with the read data read from the memory IC 2 based on a read command from the reader / writer module 13 to change the magnetic field. The read data is transmitted to the VTR 20 by giving it to the antenna pattern 12 of the reader / writer antenna substrate 11.

As described above, the VTR 20 and the cassette label 3
Data communication is performed between the reader / writer antenna board 11 of the VTR 20 and the antenna wiring 4 of the cassette label 3 in a non-contact manner by using electromagnetic coupling at a short distance from each other. Data communication can be performed unless a metal object is interposed between the antenna wiring 4 and the antenna.

When the video cassette tape 1 is inserted from the outlet 23 of the front panel 22 provided above the control panel 21 as shown in FIG. A reader / writer antenna substrate 11 is provided at a position facing the antenna wiring 4.

That is, as shown in FIG. 5, when the video cassette tape 1 is inserted from the front panel 22, the video cassette tape 1 is moved one step along the rail groove (not shown) of the side plate 32 together with the compartment 31. It is dropped down and attached to the cassette receiver 33 and the reel base 35 provided on the base plate 34. At this time, the VTR 20 is positioned so that the reader / writer antenna substrate 11 provided inside the control panel 21 and the antenna wiring 4 of the cassette label 3 on the video cassette tape 1 face each other.

As a result, the VTR 20 moves from the reader / writer antenna substrate 11 to the antenna wiring 4 of the cassette label 3.
, Data can be written to and read from the memory IC2. At this time, when writing data to the memory IC 2, the VTR 20 displays information to be written on the display unit 24 of the control panel 21 or a monitor (not shown) or reads data when reading data from the memory IC 2. The displayed information is displayed on the display unit 24 of the control panel 21 or a monitor.

Actually, as shown in FIG. 6, in the data format of the program information and the classification code recorded in the memory IC 2 of the cassette label 3, "0001" to "0063"
Up to 64 blocks, each block consisting of 16 bytes. For example, in the “0000” block, various kinds of manufacturing information on the video cassette tape main body such as the serial number of the video cassette tape itself, the date of manufacture, the capacity of the memory IC, and version information are recorded. Locked so that it cannot be changed by the user.

The block "0001" and subsequent blocks are user areas that can be used by the user, and the first "0" area of the block "0001" is recorded with a program classification code (XX). Thus, the VTR 20 can recognize the characteristics and the degree of a video scene whose viewing is desired to be restricted for a young age group included in a program recorded on a video tape.

This classification code is classified into A0, A1, and A2 for video scenes having sexual descriptions according to the characteristics and the degree of the video scenes, as shown in FIG. Are ranked as B1, B2, and B3, and C1, C
2, and C3. Incidentally, the degree of the video scene is ranked such that the classification code having a small number such as A0>A1> A2 is higher (extreme).

On the other hand, in the VTR 20, a reproduction prevention operation pattern corresponding to the rank of the classification code is set in advance based on a correspondence table as shown in FIG. In order to execute the preventive operation pattern, a classification code of a desired rank is recorded in the memory IC 2 of the cassette label 3.

That is, when the VTR 20 reads the classification code of A0, B0, C0 from the memory IC 2 of the cassette label 3 of the loaded video cassette tape 1, the video cassette tape 1 is forcibly ejected and a warning screen is displayed. Display, and when the classification codes of A1, B1, and C1 are read, the video cassette tape 1 is temporarily reproduced and then immediately stopped to display a warning screen, and A2, B
2. When the classification code of C2 is read, the reproduction operation is restricted so that only the audio is output and the video is not displayed.

Note that the VTR 20 restricts the reproduction operation based on the classification code read from the memory IC 2 of the cassette label 3. However, if the VTR 20 cannot be watched by an administrator of the video cassette tape 1 or an adult, a warning is issued. Only when a recitation number set in advance by the administrator is input on the screen, the reproduction operation can be released and the reproduction operation can be started.

Incidentally, when the video cassette tape 1 to which the cassette label 3 is not attached is loaded, the VTR 20 cannot obtain not only the classification code but also other program information such as the program title and the recording time. In such a case, the setting is made such that the loaded video cassette tape 1 is forcibly ejected.

Subsequently, as shown in FIG. 9, when a classification code is written from the VTR 20 to the memory IC 2 of the cassette label 3, the VTR 20 operates an operation button (not shown) on the control panel 21 of the reader / writer module 13 as classification information recording means. ), The classification code D1 corresponding to the feature and the degree of the video scene is input by the administrator, and the classification code D1 is transmitted to the VTR control unit 41 having a microcomputer configuration.

VTR controller 4 as reproduction operation restricting means
1 generates write command data D2 for writing the classification code D1 to the memory IC2 of the cassette label 3 based on the classification code D1 and sends it to the non-contact memory control unit 42, and also generates the non-contact classification code D1. Memory control unit 4
Send to 2. Thereby, the non-contact memory control unit 42
The program enters a write mode in which the classification code D1 is written into the memory IC2 of the cassette label 3 based on the write command data D2.

The non-contact memory control unit 42 temporarily stores the classification code D1 sent from the VTR control unit 41 in a RAM (Ran
dam Access Memory) 58, and temporarily
8 is used as a working area, a write address D3 (for example, block number "0001") for writing the classification code D1 in the memory IC2 is generated, and transmission data D4 including the write address D3 and the classification code D1 is generated. After that, this is encoded and CRC (Cyclic Redundancy)
Check) is sent to the application circuit 43.

The encoding and CRC adding circuit 43 performs a predetermined encoding process on the transmission data D4,
A code is added, and the encoded data D5 obtained as a result is sent to the mixer 44.

The oscillator 45 supplies a master clock to each circuit block (not shown) in the VTR 20, generates a carrier signal S1 having a predetermined frequency, and sends it to the filter 46. The filter 46 transmits only the carrier signal S <b> 1 having a predetermined frequency to the mixer 44.

The mixer 44 modulates the carrier signal S1 based on the coded data D5 by a predetermined modulation method to generate a modulation signal S2, and sends it to the power amplification circuit 47. The power amplifying circuit 47 outputs the modulated signal S
2 is amplified to a predetermined signal level so that the transmission signal S
3 and sends it to a reader / writer antenna substrate 11 as classification information recording means.

The reader / writer antenna substrate 11 causes a magnetic field to fluctuate by passing a current that changes in accordance with the transmission signal S 3 to the antenna pattern 12, and applies the fluctuating magnetic field to the antenna wiring 4 of the cassette label 3. As a result, in the cassette label 3, the induced electromotive force generated by the fluctuating magnetic field received by the antenna wiring 4 is supplied to the power supply unit 54, thereby activating the memory IC 2 and supplying power to each block, and generating the fluctuating magnetic field. The resulting change in current is sent to the demodulator 48 as a reception signal S4.

The demodulator 48 generates demodulated data D 6 by demodulating the received signal S 4 and sends it to the equalizer 49. The equalizer 49 generates the demodulated data D7 by compensating for the amplitude distortion and the phase distortion of the demodulated data D6, and sends this to the command analysis and memory control circuit 50.

The command analysis and memory control circuit 50 sends out the demodulated data D7 to the CRC calculation circuit 52, calculates the CRC code of the demodulated data D7 in the CRC calculation circuit 52, detects a data error, and then demodulates the data. The command contained in the data D7 is analyzed to recognize that it is a write command, and the write address for writing to the nonvolatile memory 51 is read. Then, the command analysis and memory control circuit 50 extracts the classification code D6 from the demodulated data D7, and writes the classification code D6 into the nonvolatile memory 51 according to the write address.

On the other hand, when data is read from the memory IC2 of the cassette label 3 by the VTR 20,
0 sends the read command data and the read address to the cassette label 3 based on the control of the VTR control section 41 of the reader / writer module 13 as the classification information reading means, as in the case where the above classification code is written in the memory IC2. The cassette label 3 is supplied with power based on a magnetic field received from the reader / writer antenna substrate 11 of the VTR 20, receives a read command and a read address based on the fluctuating magnetic field, and sends it to the command analysis and memory control circuit 50.

Thus, the command analysis and memory control circuit 50 enters a reading mode for reading the classification code from the memory IC 2 of the cassette label 3 based on the reading command. Command analysis and memory control circuit 50
Reads the specified classification code D10 from the nonvolatile memory 51 based on the read address, and
It is sent to the RC providing circuit 53.

The coded CRC adding circuit 53 performs a predetermined coding process on the classification code D10 and adds a CRC code, and sends out the coded data D11 obtained as a result to the modulator 55.

The modulator 55 performs a predetermined modulation process on the basis of the coded data D11 to generate a modulation signal S5, and sends it to the antenna wiring 4. The antenna wiring 4 changes the magnetic field by changing the amount of current according to the modulation signal S5.

Thus, the VTR 20 is connected to the antenna wiring 4
Pattern of a reader / writer antenna substrate 11 as a classification information reading means
And the resulting change in the amount of current is sent to the demodulator 56 as a received signal S6. The demodulator 56 receives the received signal S
6 is demodulated to generate demodulated data D12, which is sent to the equalizer 57.

The equalizer 57 compensates for the amplitude distortion and the phase distortion of the demodulated data D12, thereby obtaining the demodulated data D13.
Is generated and sent to the non-contact memory control unit 42.
The non-contact memory control unit 42 calculates the CRC code based on the demodulated data D13, performs error detection, and then reads the classification code D read from the memory IC2 of the cassette label 3.
10 is extracted and sent to the VTR control unit 41.

The VTR control section 41 causes the recording / reproducing system 60 to execute a reproduction preventing operation corresponding to the classification code D10 based on a correspondence table (FIG. 8) stored in an internal memory (not shown). The reproduction operation of the video cassette tape 1 can be restricted as intended by the administrator.

In the above configuration, the VTR 20 records the classification code according to the characteristics and the degree of the video scene of the program recorded on the video cassette tape 1 in the memory IC 2 of the cassette label 3 based on the operation of the administrator. As a result, a classification code indicating the characteristics and the degree of the video scene whose viewing is to be restricted is written in the memory IC 2 of the cassette label 3 on the video cassette tape 1.

The video cassette tape 1 with the cassette label 3 on which such a classification code has been written.
VT by younger children, contrary to the intention of the administrator
When loaded in R20, the VTR 20 first
The classification code is read from the memory IC2 of the cassette label 3 based on the control of the control unit 41.

At this time, if the read classification code has a rank of, for example, A0, B0 or C0, the video cassette tape 1 is forcibly ejected because the degree of the video scene whose viewing is to be restricted is extreme. To display a warning screen on the monitor.

When the read classification code has the rank of A1, B1 or C1, the degree of the video scene whose viewing is desired to be restricted is slightly lighter than the rank of A0, B0 or C0. The video cassette tape 1 is reproduced temporarily and displayed on the monitor screen. After that, the reproduction is stopped immediately and a warning screen is displayed.

Further, when the read classification code has the rank of A2, B2 or C2, the VTR 20 has such a level that the degree of the video scene whose viewing is desired to be restricted is not a problem compared to the rank of A0, B0 or C0. Therefore, the VTR 20 outputs only the audio of the video cassette tape 1 and does not display the video.

As described above, the VTR 20 can perform a reproduction prevention operation which is set in advance in accordance with the rank of the classification code read from the cassette label 3 of the video cassette tape 1, and can prevent a child of a young age group. Appreciation of a video scene whose viewing is desired to be restricted can be reliably prevented.

The video cassette tape 1 has a cassette label 3 on which a classification code indicating the characteristics and the degree of the video scene whose viewing is to be restricted is affixed with a pressure-sensitive adhesive 9, so that the cassette label is When the cassette label 3 is peeled off, the antenna wiring 4 and the memory IC 2 of the cassette label 3 are damaged, and the high quality paper 5 is torn. Therefore, the administrator of the video cassette tape 1 simply checks the status of the cassette label 3 of the video cassette tape 1 and determines whether or not a child of a younger age group whose viewing is to be restricted has watched or not. The state can be easily grasped.

At this time, for example, the cassette label 3 is forcibly peeled off from the video cassette tape 1 and the VTR 2
0, the VTR 20 cannot read any data that would have been obtained from the memory IC 2 of the cassette label 3.
Will be forcibly ejected. Therefore VTR2
0 means that the video cassette tape 1 is not reproduced except for the input of the personal identification number by the administrator, and that the program recorded with the video scene whose viewing is desired to be restricted is reproduced against the intention of the administrator. Can be prevented.

According to the above configuration, the VTR 20 sets in advance a reproduction prevention operation pattern corresponding to the rank of the classification code, and restricts viewing to the memory IC 2 of the cassette label 3 in the video cassette tape 1. And a classification code indicating the degree of the change, when the video cassette tape 1 with the cassette label on which the classification code is recorded is loaded, the memory IC 2
By reading the classification code from, and performing the reproduction prevention operation according to the classification code, it is possible to reliably prevent the reproduction of the video scene whose viewing is desired to be restricted.

Also, the VTR 20 records the program after and after recording the program by recording the classification code indicating the characteristics and the degree of the video scene whose viewing is to be restricted in the memory IC 2 of the cassette label 3 instead of the tape itself. The classification code can be recorded in the memory IC2 of the cassette label 3 at any time before the desired time.

In the above embodiment, the VTR

In this case, the reader / writer antenna board 11 of the VTR 20 may be provided at a position facing the cassette label 3 attached to the video cassette.

Further, in the above-described embodiment, the case where the classification code is recorded in the memory IC 2 of the cassette label 3 in a non-contact manner has been described. However, the present invention is not limited to this, and the classification code may be recorded by a bar code. The barcode may be directly written on the surface of the cassette label 3 and the barcode may be read by a dedicated reading device.

Further, in the above-described embodiment, a case has been described in which the cassette label 3 of the present invention is affixed to the video cassette tape 1 so as to restrict the reproducing operation by the VTR 20, but the present invention is not limited to this. , A label with a memory IC2 on a DVD (Digital Video Dis
