Description

Regeneration Control Method by Tape Grade of VSI System

The present invention relates to a tape grade playback control method for parental control in a VSI system having an OSD function, which records, in particular, a code for classifying a tape into an adult / junior high school / junior high school student or less in such a system in a tape control track. By screening and playing the video, the user can record a certain program at home to protect the minor from bad programs and to facilitate the careless handling and handling of the tape.

The VSI system is a device that receives various video / audio sources and records them on a cassette tape or plays back a recorded pro. A typical form thereof is shown in a system circuit block diagram as shown in FIG.

Here, a tuner 34 for receiving a regular broadcast signal from an antenna 33 of a VSI system and performing channel tuning is performed, and a phase locked loop (PLL) control is performed on the tuning signal provided by the tuner 34. A phase lock loop circuit 35, a microcomputer 32 for controlling the VSI system, an OSD unit 41 for generating an OSD screen, a VSI system memory 43, and a recording / playback deck. Deck section 36, key input section 31, RF converter 38, video processing circuit 39 for video signal processing, external TV receiver section 40, remote control transmitter 42 and remote control receiver (37) It consists of a structure including.

In the above system, when the function key is pressed through the remote control transmitter 42, the microcomputer 32 generates the OSD menu screen through the OSD 41, which is a screen interactive mode through the TV receiver 40. It was to perform a function setting operation.

On the other hand, conventionally, a variety of methods are known to prevent minors from watching the adult program in the above system, one of which is known in Korean Patent Publication No. 3669 (Patent No. 94-5846).

In this case, a bar code sticker that codes the reservation recording information is attached to one side of the video cassette tape to complete the setting of the reservation recording program with the insertion of the cassette tape, while attaching a bar code sticker for children / adults. It was designed to prevent children from seeing adult tapes.

In other words, in this technology, when a cassette tape with a bar code sticker marked with bar code information is inserted into the system, the bar code sensor installed on the system deck reads the bar code sticker contents. In case of timer reservation data, it saves it to memory and displays reservation contents as OSD character. If read barcode data is children / adult classification data, it is performing lock function and if playback is not possible for adult and barcode recognition, playback is not performed. It was made as a means of performing a process that does not.

In addition, another conventional technique is known in Korea Patent Publication No. 3769, Publication No. 94-9466, which displays a certain color on the tape label, and in the form of controlling the stop key by distinguishing the color of the label in the system It is done.

However, in the above techniques, if the user recorded a broadcast program using a normal tape instead of a pro tape, the means for preventing the minor from seeing the program content if the program content is not good for the minor to watch. Although it is necessary to take measures, in the related art, a technique for arbitrarily utilizing such a lock means by the user has not been devised, which is not preferable.

In addition, the former prior art has a problem that a minor user cannot perform this function at all if the barcode sticker is separated from the cassette tape margin or the barcode information is simply damaged.

In addition, in the latter case, additional hardware configuration is required to include at least a ten-key switch unit for registering and inputting a separate password for the underage viewing function. It has been the cause of the price increase.

An object of the present invention is to allow users to record grade codes on a tape when recording a specific program and to view the video by a password when playing a specific program so that the above problems can be solved. It is to be able to perform well.

In particular, in order to realize the object of the above example, the system includes a parental control recording processing program for registering a parental control code in a control track using an OSD program, and a parental control code from a tape registered with the parental control recording processing program. It is characterized by a playback control method for each tape grade of a VSI system performed by a parental control playback program that powers off the system, and a password unlock processing program by a password in adult mode.

Hereinafter, more specific features of the present invention will be understood by describing the same in detail with the accompanying drawings.

2 shows a main circuit block of the VSI system related to the tape grade regeneration control method of the VSI system according to the present invention.

Here, the key input unit 11 connected to the input port of the system microcomputer 12 for inputting various commands and the OSD function menu screen are called up according to the command input from the key input unit 11 during tape recording to select a user. According to the microcomputer 12 and the tape control track under the control of the microcomputer 12. The control pulse generating unit 15 and the deck unit 14 for recording data according to the tape class, the recording and reproducing system circuit unit 13 of the system, the OS unit 16 and so on.

Such a system is provided with a parental control recording processing program 100 as shown in FIG. 3A.

Here, the user calls up the OSD main menu screen through the key input unit and enters the tape recording data mode by step (step 101).

Thereafter, it is checked whether the user has one selection (step 102). If it is 1, the tape recording mode is regarded as an adult mode, and the adult code is recorded on the control track by the control head (step 103). 105, if 2, a series of processes are performed in which the normal mode code is recorded in the control track (step 106) and the recording mode is continued (step 104).

3B shows the parental control reproduction processing program 200 at the time of tape reproduction recorded by the parental control recording processing program 100. As shown in FIG.

Here, if there is a tape insertion in the system (step 201), it is checked whether it is an adult lock mode (step 202), and if there is a lock mode, the tape grade through the control head is read from the control track (step 203).

Thereafter, a series of processes are performed to check whether the grade is adult (step 204) and to turn off the power if the grade is adult (step 205).

4 shows the password unlocking program 300.

In the function menu, the user enters the password setting and release mode (step 301). If a password is entered in the password input mode, the password is recognized (step 302), and the name is checked to match the registered number (step 303). In this case, the process consists of a sequence of steps to release adult mode (step 304).

According to the present invention having the above configuration, when the user issues a command to bring up the function menu screen to the microcomputer 12 in order to record a tape grade control signal on the recording tape through the key input unit 11 as shown in FIG. Through the OS 16, a signal registration display screen for each tape class is output.

When the user presses the classification number for each tape grade displayed on the screen, the microcomputer 12 records the identification code through the control head on the control track during recording.

At this time, the recorded tape grade code can be divided into 1. adult use 2. general use or 1. adult use, 2. middle and high school, 3. middle school or less.

For example, the adult code is set to 99 for the number, the general code for 88, and the like is recorded as a pulse code on the control track.

On the other hand, when a minor plays back the tape recorded as described above, the microcomputer 12 reads the code for the tape grade of the control track at the time of playing the tape. You will not be able to.

In addition, the playback operation of the adult grade tape as described above can perform the tape playback operation if the user releases the password registration through the OS program before the tape playback.

On the other hand, such an operation is performed by the microcomputer 12 through the parental control recording processing program 100 and the parental control playback processing program 200 as shown in FIGS. 3A and 3B, which is performed by the user through the key input unit. Calls up the menu screen and enters the data record mode by tape grade.

After that, it checks whether the user has 1 selection, and if it is 1, the tape recording mode is considered to be adult mode, and the adult control code is recorded from the control head to the control track. Recording is performed and recording mode is continued (steps 101 to 106).

In addition, if there is a tape insertion in the system, the parental control playback program 200 shown in FIG. 3B checks whether an adult lock mode is used, and if there is a lock mode, the tape grade through the control head is read from the control track (steps 101 to 203). .

Then, it is checked whether the grade is adult, and if the grade is adult, the power is turned off (steps 204 and 205).

In addition, Figure 4 shows the password unlock program 300, go to the password setting and unlock mode from the function menu of the system, and enter the password in the password input mode to recognize the password, and does it match the registered number? If it is checked, the adult mode is released (steps 301 to 304).

In the present invention, since the parental control function for each tape grade can be arbitrarily used by a user setting in a VSI system having an OSD function, the viewing limit setting for each tape grade using a general recording tape can be variously performed.
