Through the screen interactive function setting operation is performed.

On the other hand, there are a number of mechanisms to prevent minors from watching adult programs in the VSI system is already known, one of which is Korea Patent Publication No. 3769 (Notification No. 94-9466).

This technology displays a certain color on the tape label, and the VSI system controls the stop key by distinguishing the color of the label.

Also, nowadays, when the adult broadcast program is recorded on the tape, the duty pulse of the control signal recorded on the tape is set to a certain ratio (adult) so that the tape is reproduced by the microcomputer during the reverse playback of the tape. After recognizing adult cognition primarily, a password must be input through an OSD screen to perform a playback operation.

In the former case, when the tape is old or the tape label is damaged, a certain color displayed on the tape label is discolored, and it is difficult to detect the problem. there was.

In the latter case, the tape maker or the user has to set up to record the control signal of the adult discrimination duty pulse separately when recording the adult broadcast program.

In order to solve the above problems, the present invention, when the user presses the play key of VSIal, detects the grade using the engraved code of the tape inserted into the deck part, and outputs the password input screen when the adult tape is detected. The purpose of the present invention is to provide an adult tape selection playback method of the VSI system that prevents minors from watching adult video tapes by executing the playback mode only when the passwords match with each other.

In particular, the present invention relates to a VSI system having a function of detecting an adult video tape under the control of a control means so that the play key is input by a remote controller to determine the grade of the tape loaded in the deck unit. A grade detection process for detecting, a password input screen output process for outputting a password input screen on an OSD screen if it is determined that the tape is an adult grade, and an input password and a preset password when it is confirmed that there is a password input by a user And a password comparison process for determining whether the passwords match each other, and executing the play mode when the passwords match each other, and executing the standby mode when the passwords do not match.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the embodiment for achieving the above object will be described.

2 is a flowchart illustrating a method for selectively reproducing an adult tape according to the present invention.

First, in order to implement the present invention, a configuration of the VSI system illustrated in FIG. 2 is required.

That is, the VSI system includes a remote controller transmitter 20 that transmits an infrared light signal corresponding to the user's selection of a function such as playback, and a remote controller that receives a predetermined control optical signal transmitted from the remote controller transmitter 20. A light receiving unit 21, a microcomputer 22 for receiving a predetermined control code signal from the remote controller receiving unit 21 to control the entire system, an OS unit 23 for generating an OSD screen, and various kinds of information A memory unit 24 for storing, a deck unit 25 for recording / playback operation under the control of the microcomputer, and a code stamping portion imprinted on the tape when the user inserts a video tape into the deck unit 25. And a code recognition unit 26 for sensing, a video signal processing unit 27 for processing a video signal, and a CRT unit 28 for outputting various screens.

An embodiment of the adult tape selection playback method according to the present invention implemented by the VSI system configured as described above is as follows.

First, when a user inserts a video tape into the VSI deck unit 25 and presses a playback function key using the remote controller 20, an optical signal corresponding to a predetermined control code is received from the remote control 20. At the time of receiving light at 21, the remote control light receiving unit 21 converts the received light signal into a predetermined control command signal and then applies it to the microcomputer 22.

In addition, the microcomputer 22 receiving a predetermined control command signal from the remote control receiver 21 checks whether a play key is input and sends a control signal to the code recognition unit 26 without executing the play mode immediately. As shown in the drawing, the tape grade detection process for detecting the code carved portion 41 located on one side of the video tape 40 is performed.

That is, the code recognizing unit 26 recognizes the code engraving unit 41 imprinted on a predetermined portion of one side of the video tape 40. For example, if the code number is 0101, the adult tape can be viewed. It is sufficient to store and store the rating information for each code number in the memory unit 24 in advance.

In any case, when the code recognition unit 26 detects the code stamping unit 41 of the video tape 40 inserted in the deck unit 25 and transmits the detected information to the microcomputer 22, the approved micro If the detection information is 0101, the computer 22 determines that it is an adult tape.

When it is determined that the tape inserted into the deck unit 25 by the microcomputer 22 is an adult tape, a control signal is sent to the OS unit 23 to output the password input screen to the CRT unit 28.

For reference, the contents of the password input screen outputted to the CRT unit 28 by the processing of the OS unit 23 may be configured as follows.

Enter the password if you want to play the inserted tape.Enter the password: * * * *

At this time, when the user inputs the password using the remote controller 20 or the like, the microcomputer 22 checks this and compares it with the password preset in the memory unit 24 to determine whether the password matches.

As a result of the above determination, if it is determined that the passwords match each other, the microcomputer 22 sends a control signal to the deck unit 25 to execute the playback mode normally. If it is determined that the passwords are inconsistent with each other, the microcomputer 22 does not execute the playback mode. Will be kept in standby mode.

Therefore, the user who does not know the password cannot execute the playback mode, thereby preventing minors and the like from watching the adult tape without permission.

As can be seen from the above description, the present invention relates to a VSI system having a function of detecting an adult video tape under the control of the microcomputer 22, and confirms whether a playback key is inputted by the remote controller 20 so that the deck can be checked. A grade detection process for detecting the grade of the tape loaded in the unit 25, a password input screen output process for outputting a password input screen on the OSD screen if it is determined that the tape is an adult grade, and a password by the user When it is confirmed that there is an input, a password comparison process for judging whether the input password and the preset password match each other, and if the passwords are matched with each other, executes the playback mode and if it does not match, the standby mode is performed. Because you can prevent the minor from watching the tape in advance It can provide a reliable function for protecting minor emotions.
