How to handle title memory by tape grade

The present invention relates to a parental control VSI system in which a tape that has already been watched can be classified and checked. More specifically, when a playback mode is selected in the parental control VSI, the grade code and title data of the playback tape are stored in a memory. After confirming the password input status, it controls the playback operation of the deck mechanism and then outputs the tape titles classified by the grade by selecting the menu on the on-screen display. The present invention relates to a method of processing title memory of each parental grade VSI for easy viewing.

In the conventional parental control VSI system, codes for each tape are set to restrict the viewing of the video screen by tape playback, and the operation of the deck mechanism is controlled based on the tape-specific codes and the passwords already stored. In particular, if a tape play key is input, the code for each tape inserted in the deck is read to determine whether it is a parental control tape, and if it is not a parental tape, the play mode is performed immediately. The password input state selected by the key input means is checked to execute the regeneration mode or maintain the mechanism stop state without executing the regeneration mode depending on whether the passwords match.

That is, when the playback mode is selected, the microprocessor performs a code checking operation to determine the type of tape inserted into the deck. When the code checking step for each tape is recognized as a viewing restriction tape (for example, an adult tape), the microprocessor Prints a message (for example, enter a password) to guide password entry on the OSD screen, waiting for the password to be entered by an external user.

At this time, if the password is entered, the microprocessor checks whether it matches the password that is already remembered. If the password matches, the microprocessor proceeds to normal playback mode. If the password does not match, the microprocessor maintains the mechanism stop mode. ) Prevents parents from watching adult tapes secretly, and again displays a message on the OSD screen that prompts you to enter your password (for example, enter your password again). Wait for re-entry.

However, in the conventional parental control VSI system as described above, the type of the tape is determined based on the parental control code detected on the tape, and in the case of the parental control tape, the previously stored password matches the new password entered by the user. It is configured to control playback and stop operation in the deck mechanism by checking, but it does not have the ability to manage the already watched tape because it does not leave the title or information of the watched tape in the record. Therefore, in the case of renting a videotape, a tape having a long history of viewing has a problem such as borrowing a videotape already watched because the user does not remember the contents well.

Therefore, the present invention was created to solve the above problems, and the present invention divides the data related to the tape code and the title detected from the tape to be played back into the memory address when the playback mode is selected in the parental control VSI, and stores the data in the memory address. After confirming the password input status, it controls the playback mechanism of the deck mechanism. Then, by selecting the menu on the OSD, it is possible to check the stored tape title and viewing date and time according to the tape code. It is an object of the present invention to provide a title memory processing method according to the viewing grade VSI, which makes it easy to recognize when the viewer has watched.

In order to achieve the above object, the present invention provides a first step of reading data about a parental control code and title indicating a tape type when a play key is selected; A second step of dividing data about a title read in the first step by code level and storing the data with date and time data; A third step of determining whether a code of a corresponding tape read in the first step is a parental control code after performing the second step; A fourth step of determining whether the input password matches the password already stored while outputting a message screen for inputting the password if the viewing result is the parental control code in the third step; A fifth step of proceeding with a playback mode if the judgment result of the third step is not the parental control code or the password of the fourth step matches the password; The sixth step of outputting the stored contents for each level memorized in the first step on the OSD screen while maintaining the stop mode if the password does not match, as a result of the determination in the fourth step. It provides a title memory processing method for each tape grade of parental control VSI.

The video circuit unit 20, the video recording / reproducing unit 10 which amplifies the video signal obtained from the video circuit unit to a predetermined level and records or reproduces it on a tape, and when the playback key is selected, the parental control code and the secret already stored. Control the deck mechanism based on the number, and if the password is wrong more than the specified number of times, maintain the deck mechanism stop state and save the record in the internal memory. Microprocessor with a series of tape limit output processing programs And an OSD processor 30 for generating OSD characters in accordance with the control signal of the microprocessor and synthesizing them to the output signal of the video circuit, and inputting a password or operating the microprocessor to the user's intention. It is preferable to include a key input unit 50 which can be selected according to the above, and a deck drive unit 40 for driving the deck mechanism according to the control signal of the microprocessor.

2 is a flowchart illustrating a process of processing a title memory for each tape grade of a parental control VSI according to an exemplary embodiment of the present invention.

As shown in the figure, the first step is a step performed when a playback key is selected. The first step is to read data about a parental control code indicating a tape type and a title (S111 and S112).

In the second step, the data related to the title read in the first step is classified according to code grades and stored together with date and time data (S113).

The third step is a step (S114) of determining whether the code of the tape read in the first step is a parental restriction code after performing the second step.

In the fourth step, if the viewing restriction code is determined as the third step, outputting a message screen for guiding the password input (S115); and a password that is already stored by the password input in the message output and standby state. In operation S116, the operation of determining whether or not coincides with.

The fifth step is a step that is performed when the judgment result of the third step is not the viewing restriction code or the password of the fourth step matches the password. The fifth step is to control the deck mechanism to proceed to the normal playback mode (S117).

The sixth step is performed if the passwords do not match as a result of the determination in the fourth step, controlling the deck mechanism to maintain the stop mode (S118), and the menu selection key and the graded data in the deck mechanism stopped state. Judging whether the selection keys are input in turn (S119); if the menu and data selection key for each grade are input in turn, outputting a menu selection screen and a data selection screen for each grade on the OSD (S120); and in the output state Determining whether or not to enter the confirmation number for each grade (S121), and if the grade-specific confirmation number is input, it indicates that the step of outputting the stored contents of the corresponding grade memory in the first step on the OSD screen (S122).

The operation of the present invention as described above is as follows.

First, in the present invention, the microprocessor 60 reads the tape grade code and title data detected from the tape when the playback key is input through the key input unit 50, and divides the code into various grades according to the code (S112). The first step and the second step of dividing the memory by address and storing the title data and the date and time data in the form of a table together in the address of each memory are sequentially performed.

Next, after performing the second step, the microprocessor 60 checks the code detected on the tape to determine whether it is an adult tape (S114), and if it is a parental control code (adult tape), controls the OSD processing unit 30 to keep it secret. A third step and a fourth step of waiting for a password to be input through the key input unit 50 are performed while outputting a message guiding a number on the OSD screen (S115).

At this time, if the tape is not an adult or a password is input, if the newly input password matches the previously stored password, the fifth step of performing a normal playback operation (S117) is performed.

On the contrary, if the passwords do not match, it is determined whether the menu selection and grade data selection keys are input in the state of maintaining the stop mode (S118), and when the menu selection and grade data selection keys are sequentially inputted on the OSD, Scheduled Recording, Channel Search, Clock Custom,… as shown in Table 1 and Table 2 … , Menu selection screen with message such as checking data by grade, viewers, minors, adult,… … While the data selection screen for each grade is displayed on the OSD in turn (S120), the data check number for each grade is again inputted.In this case, if the data confirmation number for each grade is input, it is output again through the OSD screen as shown in Table 3 below.
