Description

Display method of viewing range according to multiple viewers in TV with parental control

The present invention relates to a method for displaying a viewable range according to a plurality of viewers in a television having a parental control function, and more particularly, to a viewable range according to a viewer in a television having a violence chip (V-CHIP) function. The present invention relates to an apparatus for uniformly displaying a viewing range for each viewer by OSD when setting a viewing range for a plurality of viewers for each viewer.

Recently, televisions have been recorded in accordance with the classification information such as the grade of a program and transmitted according to the password inputted by the information according to the stored viewer password, which is encoded and transmitted together with the broadcast signal when the television is broadcast. It includes a V-chip function that prevents viewing by limiting the type, grade, or time zone, that is, the viewer limitation function for each viewer.

An example of the internal configuration of a general TV receiver having its parental control function is shown in FIG. 1 as a block diagram.

As shown in FIG. 1, the TV receiver comprises an antenna 1, a tuner 2, a V-decoder or data decoder 2 ', which is a main component of a V-chip function, and generally a chroma IC to a main IC. IF amplifier unit 3, P / S separation unit 4, audio detector 5, image detector 6, audio processor 10, OSD generator 13, image processor 14 and Mixer 15, remote control unit 7, receiver 8, microcomputer 9, E ² PROM 9 'as memory means, voice amplifier 11, speaker 12, CRT driver 16 and It is configured to include a CRT (17).

The broadcast signal of the airwave is received by the antenna 1, and the broadcast signal received by the tuner 2 controlled by the microcomputer 9 is tuned. The IF amplifier 3 amplifies an intermediate frequency (IF) signal output from the tuner 2, and the P / S separation unit 4 includes a surface acoustic wave filter to convert the intermediate frequency (IF) into an image intermediate frequency ( PIF) and voice intermediate frequency (SIF).

The voice detector 5 detects a voice signal from the voice intermediate frequency (SIF), and the voice processor 10 detects the detected voice signal based on the control signal of the microcomputer 9 (Base) and Treble. Voice processing such as volume, volume, etc. is performed, and the processed voice signal is amplified by the voice amplifier 11 and output to the speaker 12.

The image intermediate frequency PIF is detected by an image signal in the image detector 6, and the image processor 14 detects the color, tint, brightness, etc. according to the control signal of the microcomputer 9. Processing to output R (Red), G (Green), B (Blue) and luminance (Y) signals corresponding to the image signal, and the R, G, B and luminance (Y) signals are displayed on the OSD in the mixer 15. By mixing and outputting the R ', G', B 'and OSD blanking signals Y' generated from the generator 13, the CRT 17 is driven through the CRT driver 16, and the OSD generator 13 is The image is displayed together with the predetermined OSD pattern data from.

In addition, the remote control device 7 is a device for the viewer to control the output volume, channel switching, etc., or to remotely control the overall device, and transmits an infrared signal and receives it from the receiving unit 8 of the television to convert it into an electrical code signal. By converting and outputting to the microcomputer 9, the overall apparatus is controlled by the microcomputer 9 in accordance with the electrical code signal.

On the other hand, the program classification information data is decoded by the data decoder 2 'from the composite video signal transmitted by encoding program classification information data according to a program type, a degree of violence or obsceneness, etc. to a broadcast signal, and the decoded information is decoded. The program classification information data is stored in the memory means 9 'by the microcomputer 9 at power input, channel change, program change or periodically. In addition, the viewer-specific password input through the menu and the parental control range such as the rating are stored in the memory means 9 '.

Then, when inputting the power source of the television or when changing the channel or inputting new program classification information data, the microcomputer 9 is required to input the password of the viewer, and the viewing corresponds to the viewer password that matches the input password. When the restriction range is compared with the program classification information data, the transmission of the video signal of the program is blocked by the microcomputer 9 so that it cannot be viewed when it is within the viewing restriction range, and the viewing range is not within the viewing restriction range. You can watch normally.

Although not shown, the video signal input from V-Cal may also be subject to the parental control function as described above.

However, in the case of setting the TV viewable range by the viewable range setter in the conventional V-chip setting, in order to find out what range the viewable grade is set for each user, the viewable range of one person at a time I had to know the information. Accordingly, when setting the viewing range of many users at once, it is not easy to check information on each user.

Accordingly, the present invention is to solve this problem, when setting the viewing range of a large number of users at the same time by the setter is set by uniformly displaying the range that each user can see at the same time at the same time before exiting the menu An object of the present invention is to provide a viewable range display method according to a plurality of viewers in a television having a viewing restriction function capable of identifying a range.

As shown in FIG. 2, the method for displaying a viewable range of a television according to a plurality of viewers according to the present invention includes selecting a rating level setting mode 100, a rating level setting 200 for each user, and a setting confirmation display step 300. Then, the viewing channel reset step 400 is performed.

In a television with V-chip capability, the viewable ranger can set for each television user a rating channel or time that can be viewed according to the requirements of the individual or other circumstances.

First of all, the setter must select a viewing grade setting mode for setting the viewing range in the full function menu (100). The setter who selected the rating setting mode in the entire menu sets the ratings for each user and stores them in the memory (210, 220). At this time, since the viewable grade channels are stored in the memory for each user, the grade of viewable grades must be displayed for each user later. It can be specified, or the setter can designate a channel that can be viewed by each user for each user. For example, the range of channels that user 1 can watch is TV-Y, TV-Y7, TV-G, and the range of channels that user 2 can watch is TV-Y, TV-Y7, TV-G, TV- Can be specified with EG. When setting the ratings for all users or if the setter wants to finish the operation, the setter may select the set-up selection menu (230).

Once the rating setting is completed, the confirmation display step 300 is performed. That is, the information in which the viewable range is set by the setter is stored in the memory, and under the control of the microcomputer, the information set so far is displayed on one screen uniformly. At this time, it is displayed by user and channel in table format. As shown in FIG. 3, User 1, User 2, User 3,... 310 and TV channels 320 allowed for each user are listed. If the setting contents displayed on one screen are different from those intended by the setter or are corrected, the modification menu is selected from the selection menus 330 and 340 to enter an editing operation or complete the setting of a rating.

According to the configuration and operation of the method for displaying the viewable range of television according to the multiple viewers according to the embodiment of the present invention described above, when setting the viewing range of many users at once by the setter, By displaying the range that the user can see all at once with the OSD, it is possible to check the set range by setting the viewing range setting according to the setter's viewing range.
