Abstract

A method for setting a program viewing limit rating in an image display device is provided to allow a user to easily set the viewing limit rating although the user does not understand a difficult rating system accurately in a TV which provides the program viewing limit rating. A user sets a current program viewing limit rating(S201). A control unit confirms the current program viewing limit rating(S202). The control unit judges whether a program viewing limit rating previously set up exists(S203). When the program viewing limit rating previously set up exists, the control unit compares the current program viewing limit rating with the program viewing limit rating previously set up. When the current program viewing limit rating is lower than the program viewing limit rating previously set up, the control unit changes the program viewing limit rating previously set up to the current program viewing limit rating(S204).

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for setting program parental control of a video display device, and more particularly, to a method for easily setting parental control in an analog or digital TV.

In general, a video display device is a display device such as a TV, a monitor, etc. The TV is an image medium that is easily accessible to modern people, and broadcasts various genres of programs for each layer, that is, for adults, adolescents, and children. In particular, the specific broadcasting programs show sensationality and violence that may adversely affect the emotions of the youth or children's class. Therefore, there is an urgent need to limit the broadcasting programs according to the characteristics of the class.

Therefore, in Korea, it is possible to mix and transmit a Kbps signal in which a program ID is inserted into a broadcast signal and to determine which layer the program currently being broadcast is targeted to.

In addition, in the United States, the Federal Communications Commission (FCC) is a TV set sold in the United States to protect youth from pornographic and violent screens or languages during public or cable television programs as a way to address youth violence. The application of the V-CHIP was mandated. When the implementation time was examined, starting on July 1, 1999, the V-CHIP should be applied to TVs with 13 'or more of production models. V-CHIP is applied to the model.

Parental Instructions by Parents American Film Association Rating TV-Y Suitable for all children G Suitable for all ages TV-Y7 Suitable for children 7 years and older PG Unsuitable for children TV-G Suitable for all ages PG-13 Unsuitable for children under 13 TV-PG Unsuitable for children R Under 17 years old TV-14 Unsuitable for children under 14 NC-17 Ineligibility under 17 TV-MA 17 years old and older X Adult

Defined based on parental guidelines TV-Y TV-Y7 TV-G TV-PG TV-14 TV-MA Scene SOME INTENSE EXPLICIT Adult language INFREQUENT COARSE STRONGCOARSE violence FANTASY MODERATE INTENSE GRAPHIC Sensational dialogue SOME INTENSE CRUDE

At this time, the V-CHIP rating defines the ratings of TV broadcast programs by age by the parental guidelines or the American Film Association, as shown in Table 1, or the ratings of videos or movies by content, as shown in Table 2. Each broadcaster and video producer compulsorily stipulates that the broadcasting grade of the broadcast program is placed on the 21st line of the vertical blanking signal to meet the above-mentioned criteria.

Therefore, screen blocking, audio muting, and caption character deletion are performed when a signal corresponding to a parental control level is input that violates a preset broadcasting grade in a TV set in which V-CHIP is installed.

At this time, the parental level is set by the user, that is, the guardian can understand the parental guidelines or the ratings of the American Film Association through a manual or the like. When entering through a process such as input to enable viewing of the corresponding grade, if it is impossible to view '0', it should be set directly as 'X'.

TV-Y O TV-Y7 X TV-G X TV-PG X TV-14 X TV-MA X G O PG X PG-13 X R X NC-17 X X X

Under 7 7-13 years old 13-14 years old 14-17 years old 17 years old and younger adult TV-Y O O O O O O TV-Y7 X O O O O O TV-G X O O O O O TV-PG X X O O O O TV-14 X X X O O O TV-MA X X X X O O G O O O O O O PG X O O O O O OG-13 X X O O O O R X X X O O O NC-17 X X X X O O X X X X X X O

For example, as shown in Table 4, if the viewer who wants to restrict the viewing, that is, the child is 6 years old, set the viewable rating to '0' only for TV-Y and the rest to the parental level, that is, 'X'. If the child is 15 years old, set the 'X' only for the TV-MA, NC-17 and X, and set the rest to '0' and then turn the parental control mode on.

However, such a rating system has a disadvantage in that it is complicated for a user to understand and difficult to actually set.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to provide a method for the user to easily set the parental control even though there is no accurate understanding of a difficult rating system in a TV providing the program parental control. There is.

A first embodiment of the TV viewing restriction method according to the present invention configured as described above will be described with reference to FIG. 2.

2 is a flowchart illustrating a method of restricting viewing of an image display device according to an embodiment of the present invention.

Step 201 is a process of pressing the parental control button on the remote control. If a user wants to restrict the viewing of a program that is higher than or equal to the grade of the program currently being viewed while the user is watching the program being played on the video display device, the parental control button provided on the remote control is pressed. Press For example, if the user is watching TV, the user can select any of TV-Y, TV-Y7, TV-G, TV-PG, TV-14, and TV-MA. If you want to limit the ratings of the currently broadcast program without needing to know whether it is possible to set by simply pressing the parental control button provided on the remote control. It is not necessary for the user to use the remote control to set the parental control. If a user has a separate button on the video display device and wants to set the parental level, it is also preferable to set the parental level of the program or more by pressing the button.

Step 202 is a step of checking the parental level of the current program. In the case of a program broadcast from a video display device, the program itself includes image rating information of the corresponding program. Therefore, the image display device analyzes the information and extracts rating information of the currently broadcast program.

Step 203 is a process of determining whether the parental level is set, and is a process of determining whether the current video display device has previously set the parental level.

Step 204 is a process of setting a current parental level when the current video display device has previously set a parental level in step 203. The parental level is compared with a previously set parental level. If the previously saved parental level is lower than the current parental level of the current program, the previously saved parental level is maintained, and the previously saved parental level is maintained. If it is higher than the parental level of the program, the parental level of the current program is stored in the video display device. The data storage means may use a generally known data storage means, but it is preferable to use a nonvolatile memory in which the stored data is not deleted even if the power is cut off.

In step 205, step 204 is a process of starting the parental control setting when the current video display device has not previously set the parental control in step 203. The parental level setting of the current video display device is started, and the parental level of video is preferably set to be equal to or higher than that of the program currently being broadcast.

In step 206, a parental control password is set, and a password is set to enter a menu for modifying the stored parental control information. This step is not a mandatory process but may be skipped if necessary.

Step 207 is a process of limiting viewing of a program. If a user attempts to watch a program higher than the video rating of the set program when the user watches another program, the video or audio signal is blocked to provide no content to the user. Do not In general, blocking both video and audio signals is more efficient for viewing restrictions.

As described above, it has been described with reference to the preferred embodiment of the present invention, but those skilled in the art various modifications and changes of the present invention without departing from the spirit and scope of the present invention described in the claims below I can understand that you can.

As described above, according to the present invention, the user can easily set the parental control even without accurate understanding of the complicated rating system.
