Description

Regeneration prevention control method using barcode

The present invention relates to a method for preventing playback of a VRC using a bar code, and requires a user to input a bar code card to a bar code scanner to read a bar code recorded with password information when a user inputs a play mode key. The present invention relates to a method for preventing reproduction of V-Cal using a bar code that compares the decoded password with the reproduction permission password stored in the microcomputer to prevent the reproduction operation if it is not the same.

In general, a VRC system refers to a device capable of recording a video and audio signal on a magnetic tape wound on a reel of a video cassette and reproducing the video and audio signal. In addition, such a VR system is in principle the same as a tape recorder, but since the frequency band of the video signal on the magnetic tape is wider than that of the audio signal, it is necessary to increase the relative speed of the head for recording and reproducing the video signal. Therefore, the head drum provided with two, four or six heads is rotated at a speed of several tens of seconds per second inclined with the tape traveling direction to record and reproduce the video signal.

V-AL's main function is to play video tapes. The video tapes sold and rented are graded according to the contents contained in them, and the color of the tape case and the tape label is different so that the grades can be easily distinguished. Doing. Because the rating of this video tape indicates whether or not to view the video based on the age of the person who can watch it, it is recommended that the person who cannot watch the video of the indicated grade (non-elementary grade) should not watch the video tape of the grade which should not be watched. In order to sell and rent video tapes, video tape rental and sales companies must confirm the age of customers before selling and renting video tapes.

However, conventional VRs do not have the ability to limit the playback of the tape, so that the rental and sales of video tapes cannot be viewed by the burner by simply checking the age of the customer when renting and selling the video tape. There was a problem that can not effectively limit the viewing of the tape.

The present invention has been invented to solve the above problems, and when the user inputs the playback key, the barcode card is required to approach the barcode scanner so that the barcode with which the reproduction permission password information is recorded can be read, and the barcode read It provides a playback prevention control method of V-CAL that can restrict the viewing of video tapes that do not meet the parental control level by comparing the decoded password with the playback permission password stored in the microcomputer. Has its purpose.

In order to achieve the above object, the present invention provides a play mode key input determination step of determining whether a play mode key is input in a state in which a user turns on a V-Cal and a video cassette is loaded, and determines the play mode key input. If it is determined that the playback mode key is input in the step, after the bar code access request message output step of outputting a message requesting to access the bar code card to the bar code scanner to read the bar code, and the bar code access request message output step, A bar code judgment step of judging whether or not the read password is the same as the reproduction permission password stored in the bar code, and if it is determined at this bar code determination step that the password decoded the bar code is the same as the stored reproduction permission password, the playback operation is performed. The playback stage, this playback stage A power off key input determination step of determining whether a user inputs a power off key while performing a normal operation of V-Cal, and if the user inputs a power off key in this power off key input determination step, playback is performed. A reset step of resetting the prohibition function flag, and a power off step of turning off the power after performing the reset step.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 and 2, the barcode to which the present invention is applied is installed on the front panel 1 of the RFID to read a barcode in which the reproduction permission password information of the barcode card 2 is recorded. (3), the barcode decoder 4 which decodes the barcode signal read by the barcode scanner 3, and the reproduction permission password data decoded by the barcode decoder 4 is input and compared with the stored password. A microcomputer 5 for controlling overall functions of the system including performing a prevention function, a key input unit 6 for inputting a user's function selection signal to the microcomputer 5, and the key input unit 6 When the playback mode key is input through the OSD character generator 8 to generate the OSD character according to the OSD control signal of the microcomputer 5, the OSD generated by the OSD character generator 8 And receiving the character signal processing the image signal comprises a video signal processing unit (9) for outputting to a display (7).

The video signal processor 9 receives a video signal reproduced from the head 11 that reads the video signal recorded on the video tape 10, processes the video signal, and outputs the image to the display 7. The signal processor 12 processes the voice signal reproduced from the head 11 and the voice signal input and recorded from the outside, and the voice signal processed voice signal is output to the outside through the speaker 13.

In addition, there is a capstan motor 16 which drives the supply reel 14 and the reel 15 so that the video tape 10 can proceed under the control of the microcomputer 5.

As shown in FIG. 3, the present invention applied to such a VR is first performed by the user by turning on the VR and proceeding to the playback mode key input determination step S2 in the initial state S1 where the video cassette is loaded. It is determined whether the playback mode key is input. If it is determined in the reproduction mode key input determination step S2 that the reproduction mode key has not been inputted, the process ends.

However, if it is determined in the playback mode key input determination step (S2) that the playback mode key is input, the process proceeds to the bar code access request message output step (S3) to request the barcode card to approach the barcode scanner to read the playback permission barcode. Print a message to the OS screen. After performing the barcode access request message output step S3, the procedure goes to the barcode determination step S4 to determine whether the password decoded the read barcode is the same as the stored reproduction permission password.

If it is determined in the barcode determination step S4 that the password decoded the barcode is not the same as the stored password, the barcode card is returned to the barcode access request message output step S3 to read the reproduction permission barcode. Display a message on the OS screen asking you to access the scanner.

On the other hand, if it is determined in the barcode determination step S4 that the password decoded the barcode is the same as the stored reproduction permission password, the process proceeds to the reproduction step S5 to perform the reproduction operation. In operation S6, the controller performs the corresponding function according to the user's function selection key input, and proceeds to the power off key input determination step S7 to determine whether the power off key is input. If it is determined that the power off key is not input in the power off key input determination step S7, the process returns to the normal operation step S6 and performs the corresponding function according to the function selection input of the user.

On the other hand, if it is determined that the power-off key is input in the power-off key input determination step (S7), the flow proceeds to the reset step (S8) to reset the play prevention function flag, and the power-off step (S9) proceeds to power-off the VR. Then exit.

That is, when the user inputs the power-on key to the microcomputer 5 through the key input unit 6, the microcomputer 5 powers on the V-Cal. In the state where the video tape is loaded, the microcomputer 5 determines whether the playback mode key is input through the key input unit 6.

When the reproduction mode key is input through the key input unit 6, the microcomputer 5 outputs the OSD control signal to the OSD character generator 8. Then, the OSD character generator 8 inputs an OSD character signal of a content requiring the user to approach the barcode card to the barcode scanner so that the reproduction permission barcode can be read, and inputs the image signal processor 9 to the image signal. The processing unit 9 outputs on the screen of the display 7.

Then, when the user approaches the barcode card 2 to the barcode scanner 3 according to the message output on the display 7, the barcode scanner 3 installed on the front panel 1 of VLC reads the barcode signal. The barcode decoder 4 inputs the password data which decoded the barcode signal to the microcomputer 5. The microcomputer 5 determines whether the password decoded the barcode is the same as the stored reproduction permission password, and if it is determined that the data decoded with the barcode decoded the password is not the same as the stored reproduction permission password, the microcomputer 5 selects the OSD. The OSD control signal is output to the character generator 8. Then, the OSD character generator 8 inputs an OSD character signal of a content requiring the user to approach the barcode card to the barcode scanner so that the reproduction permission barcode can be read, and inputs the image signal processor 9 to the image signal. The processing unit 9 outputs on the screen of the display 7.

On the other hand, if it is determined that the password decoded the barcode is the same as the stored reproduction permission password, the microcomputer 5 outputs a motor drive control signal to the capstan motor 16 to drive the winding reel 15, When the video tape 10 proceeds according to the driving of 15, the video signal read from the head 11 is processed by the video signal processor 9 and output on the screen of the display 7. The voice signal read from the head 11 is processed by the voice signal processor 12 and output through the speaker 13.

If the user inputs a slow screen, fast screen, stop screen, fast forward, rewind, and stop function keys to the microcomputer 5 through the key input unit 6, the microcomputer 5 receives the V-Cal. It performs the normal function input by controlling.

While controlling such a normal function, the microcomputer 5 determines whether there is a power-off key input through the key input unit 6, and if it is determined that there is no power-off key input, the microcomputer 5 continues to perform the current mode, but power-off. If it is determined that there is a key input, the microcomputer 5 resets the play prevention function flag and outputs a power control signal to a power control unit (not shown) to power off the V-CAL.

Here, the reason for resetting the anti-playback flag is that once VRL is powered off and then on again and the play mode key is input, the barcode card is accessed to the barcode scanner so that the play permission barcode can be read from the beginning. This is to compare the read-out barcode with the read permission password stored in the microcomputer and perform the play prevention function to limit the play operation if it is not the same.

The present invention reads the password on the magnetic tape attached to the video cassette from the head installed in the deck when the video cassette is inserted and loaded into the deck as described above, and when the user enters the play key, the play permission password information is read. It requires the barcode card to be accessed by the barcode scanner so that the recorded barcode can be read and compares the read barcode with the password of the read permission stored in the microcomputer to prevent playback if not identical. This has the effect of restricting the viewing of video tapes that do not meet the limits.
