Hereinafter, an embodiment of the present invention for achieving the above object in detail.

Referring to FIG. 1, FIG. 1 is a block diagram showing an embodiment of a playback lock device of a VR, according to an embodiment of the present invention, and receiving a signal according to a predetermined video tape playback from a predetermined deck and displaying the same on a predetermined screen. A video signal output unit 10 for signal processing to output a video signal, a sync separation unit 20 for receiving a video signal from the video signal output unit 10 described above, and separating and outputting a synchronous signal; A data separation unit 30 which receives a video signal from the video signal output unit 10 and separates and outputs a predetermined code recorded on the video tape based on the synchronization of the synchronization signal separation unit 20 described above; In response to a predetermined key input, the microcomputer 40 for controlling the desired function of V-Cal, the output of the above-described synchronous separator 30 and the output of the above-described data separator 30 are applied. If the code recorded on the videotape is detected and decoded, and the videotape played back is not allowed to be a minor, a prompt message for inputting a password is displayed on the screen as described above, and the key input from the microcomputer 40 described above is preset. When the password is the same, the decoder 50 allows the video signal from the video signal output unit 10 to be normally output. The font information for the OSD display and the information according to the code are stored. When the request of 50), the storage unit 60 for outputting the corresponding information to the decoder 50 described above, and if the password input is wrong, the blue back digital signal is received from the decoder 50 described above and converted into an analog signal. The above-described video frame reproduced under the control of the digital / analog converter 70 to output and the decoder 50 described above. If the IF is not minor, the OSD signal is received from the decoder 50 as described above, and a message for inputting a password is displayed on the screen as described above. And a switching unit 80 for outputting a video signal and selectively outputting a blue back signal converted into an analog signal from the digital / analog converter 70 described above when the input password is incorrect.

The present invention thus made will be described in detail with reference to FIG. 2 as follows.

First, the video signal output unit 10 receives a signal according to a video tape playback loaded on the deck from a predetermined deck of V-Cal and outputs a video signal by processing the signal to be displayed on a predetermined screen. The synchronization separator 20 receives the video signal from the video signal output unit 10 described above, and separates and outputs the synchronization signal.

Next, the data separating unit 30 receives the video signal from the above-described video signal output unit 10 and is not allowed to be a minor or minor recorded on the above-described video tape on the basis of the synchronization of the above-described synchronization signal separating unit 20. The microcomputer 40 separates and outputs a predetermined code for indicating a function, and the microcomputer 40 communicates with the decoder 50 described above to control a desired function of the VRC according to a predetermined key input.

Accordingly, the decoder 50 receives the output of the above-described sync separating unit 30 and the above-described output of the data separating unit 30 and refers to the data recorded on the video tape described above with reference to the data of the storage unit 60. If the video tape to be detected and decoded and played back is not allowed to be a minor, a prompt message for inputting a password is displayed on the screen as described above. The video signal from the unit 10 is outputted normally.

In addition, the storage unit 60 is composed of a memory device such as an EPROM to store the Hangul font information for the OSD display and the information according to the code described above, when the above-described request from the decoder 50 described the information The digital-to-analog converter 70 receives the blueback digital signal from the decoder 50 as described above, converts the analog signal into an analog signal, and outputs the blueback screen.
