TV Password Management

The present invention relates to a password management method of a television. More specifically, a password for setting a V-CHIP for showing or blocking a screen of a television according to a grade of a received program is separately determined according to a user and a program grade. A password management method for a television to be managed.

With the development of broadcasting, telecommunications, and electronic technologies, the use of television has become widespread and common to the public, and now television is becoming a powerful means of transmitting information that replaces conventional print and radio media. In addition, with the development of the video and film industry, various kinds of dramas and movies that have not been seen in the past are produced and broadcasted through TV. As TV is spread to all homes, family members can always watch.

TV is a device that receives a radio wave that is broadcast and displays it on the screen as it is possible to watch from adults to children at home. Thus, unlike conventional cinemas, televisions have a problem in that only adults who can be included in dramas or movies can expose violent and sexual scenes to children and adolescents without any filtering. For this reason, the censorship of television programs has always been a social issue.

However, a television, a mass media medium that needs to broadcast all programs of various contents for cultural, social, and entertainment purposes, cannot always broadcast programs that all family members can watch. Accordingly, there is a need for the ability to filter incoming programs.

In response to these needs, the Consumer Manufacturers Association (CEMA) was founded on 1 October 1997 by the International Broadcasters Association, the Motion Picture Association, and a group of educators and parents. I approved the TV Parental Guideline, which was filed under). After CEMA's decision, Chairman ED Markey called the technology V-CHIP and suggested that it be included in all television sets.

The V-CHIP sends a packet containing the rating information of the program currently being broadcast along with the caption signal sent to the 21st scan line of the television broadcast signal. A semiconductor chip that controls permitting / blocking, which was invented by the engineering committee of CEMA.

According to the TV Parental Guideline, the ratings of the programs are TV-Y, a rating for all children, TV-Y7, a rating for children ages 7 and older, TV-G, a rating that is appropriate for most viewers, and TV, where parental guidance is required. -PG, TV-14, a parental ban, TV-14, and adult-only TV-MA. Packets received by V-CHIP are used to determine the rating of the program the program is currently receiving and the nature of the scene to block for each rating. Contains information that represents. For each class, there is information indicating a scene of fantasy violence (FV), violence (V), sexual scene (S), adult language (L), and seductive conversation (D).

The V-CHIP blocks the program according to the combination shown in FIG. 1 when receiving information indicating the nature of the scene to be blocked in a particular scene in the program, with respect to the class of the received program. The blocking of the program is performed by expressing the image unrecognizably, removing the voice, and removing the subtitles associated with the program.

The V-CHIP does not work at any time, and the user must be able to activate and deactivate the V-CHIP. However, there may be more than one user operating a television in the home, among which there may be children who need to be restricted from viewing the program, so the ability to activate or deactivate V-CHIP should be limited by passwords.

Here, there may be at least one child user who must be restricted to viewing the program, and at least one child user may be of various age groups. Therefore, each child user should be able to have different viewing restrictions. To this end, each child user is subject to different program viewing restrictions, and each child user must have his or her own password for viewing the program according to the program viewing restrictions imposed on them.

On the other hand, in order to restrict the viewing of the program to one or more children users, it is necessary to set a password of the corresponding level for watching a program of a specific level by placing a password for each level of the received program.

Accordingly, the present invention has been made to solve such requirements, and a first object of the present invention is to provide a password management method for a television according to a user to specify a password separately according to a user's name and set a program viewing condition. have.

In addition, a second object of the present invention is to provide a password management method of a television according to a program grade in which a password is separately specified according to the grade of each program and a program viewing condition of the grade is set.
