The present invention uses information about an audience who can watch a program included in an extended data service (EDS) transmitted from a broadcasting station in a television having a caption / text broadcasting receiver. In the case of a particular program, the present invention relates to a method for restricting viewing of a particular program when watching a television, in which a youth or a child is prevented from being exposed to the media inadvertently.

In recent years, with the widespread use of television and the fact that almost all homes have at least one television, television has become an important carrier of information for the general public. Caption / text broadcasting, which was started by using the same method, can be regarded as a realization for information transmission using such a television.

In addition, since caption / text can transmit various information as well as contents related to television broadcasting, it has been the subject of many studies on how to use television caption / text broadcasting as a medium for transmitting various information to related parties and developers. come.

At the same time, the necessity of standardization in caption / text information transmission in order to prevent disordered overflow of information due to the complexity and diversification in using such caption / text broadcasting for information transmission, and finally in 1992 On October 22, the data to be transmitted to the caption / text broadcasting line, that is, the specification of the contents and transmission method of ESD, was proposed and released in draft EIA-608, and the EDS for the caption / text broadcasting in the future was draft EIA. There is a high possibility of transmission to a television in accordance with the specification of -608.

The present invention utilizes the EDS data transmission method according to the proposed standard of the draft EIA-608 as described above, and inputs a password when receiving a specific program among the contents of the EDS data, in particular, using information on the audience who can watch television programs. Built-in program that enables viewing only by the user, and by installing a password mode key on the key input device or the remote control, the user can easily protect the viewer from a specific program by inputting the password mode key. The purpose of the present invention is to provide a restriction method of viewing.

In addition, when watching a TV of adolescents and young children, a method of restricting the viewing of a specific program when watching a TV that protects adolescents and children from bad programs by assigning a password to restrict viewing can be prevented. Providing for other purposes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically showing the configuration of an apparatus for carrying out the present invention.

In a television including a caption / text broadcast receiving apparatus, a broadcast signal including a caption / text sent from a broadcasting station is received by the tuner unit 10 in the television and passed through the intermediate frequency IC 20, and then the broadcast signal. The caption / text data transmitted to the image processing unit 30 for various processing for output to the screen of the TV and transmitted during the 21st vertical blanking period is sliced by the data slicer 40 and sent to the decoder 50. Lose.

The EDS data extracted by the data slicer 40 is decoded by the decoder 50 and applied to the microcomputer 60.

At this time, the microcomputer 60 drives the program according to the present invention based on the input data code.

2A to 2B are process flow diagrams of the microcomputer 60 according to the present invention, that is, FIG. 2A is a main process flow diagram according to the present invention.

Regarding the second diagram, the following is described.

As shown in (a) of FIG. 2, in the television viewing of the present invention, the parental control method for a particular program includes checking (A) whether a password input mode key is turned on, and in step (A), a password input mode. Checking whether the control code is 01h or 02h if the key is on (B), and if the control code matches, checking whether the carrier code is 05h indicating that the EDS data to be transmitted contains information about the audience; If the step (C), the process of the three steps (A, B, C) is satisfied, then input the next EDS data code, each code of the information data about the entered audience is mode '1 'Or all' 0 ', if all the' 1 ', everyone can watch the password input mode, and if all' 0 ', nobody is allowed to view the mode immediately because 5E) point If the step (D) to check the step (D), as a result of the check is not both '0' and '1', step (E) is performed.

The password processing routine performing step (E) may include loading (1E) a pre-stored age limit, checking a corresponding bit of the EDS data code corresponding to the age limit (2E), and bit (b0). If 1) is '1', branching directly to the viewable mode 5D, and if the bit b0 is '0', requesting the viewer to input a password (3E), the password entered by the viewer (4E) checking whether or not is corrected against the stored password, by sending a power-off signal to the power control unit (11) to continue watching if it is correct in step (4E) and to stop watching if wrong. Step 5E stops watching.

When viewing the television of the present invention made of the flow as described above in detail based on the action and effect as follows.

First, the transmission method of the EDS data proposed and proposed by the draft EIA-608 will be described. The EDS data is transmitted together with the caption / text data in the 21st vertical blanking period of the television broadcast signal. In contrast to using either 1 or field 2, EDS data uses only field 2.

In addition, the EDS transmission is composed of a control code for indicating the start or transmission of the EDS transmission, a carrier code for informing information about the content of data to be transmitted, and an actual data code.

Details are shown in detail in draft EIA-608, where the code used in the present invention, the control codes indicating that the EDS information is currently being used and the start or transmission of the EDS transmission are 01h and 02h, and the EDS data EDS carrier code indicating that the information about the audience is 05h, the EDS data code for indicating information about the audience consists of two carrier codes, the present invention uses only the first character.

At this time, bit b5 of the first character code is male, bit b4 is female, bit b3 is elderly, bit b2 is adult, bit b1 is teenager, bit b0 is child. In this case, when the bits b5-b0 are set to '1', the corresponding audience may watch. If the bits are set to '0', the audience is not appropriate for the audience. Indicates.

The EDS configured as described above is serviced by the transmitting broadcast station using field 2 during caption / text data transmission. Like the broadcast signal, the EDS is received by the tuner unit 10 and frequency filtered by the intermediate frequency IC 20. Only the EDS data is sliced by the slicer 40 and sent to the decoder 50.

The microcomputer 60 analyzes each EDS code decoded and input by the decoder 50 to execute the command of the present invention. That is, it is checked whether the password input mode key of the present invention is turned on (A). Check whether the control code is 01h or 02h (B), and if the control code matches, check whether the carrier code is 05h indicating that the EDS data to be transmitted contains information about the audience (C). )do.

If the process of the three steps (A, B, C) is satisfied, the next input EDS data code is input to determine whether each code of the input data for the audience is mode '1' or all '0'. Check (D), if the mode is '1', anyone can watch the end of the password input mode of the present invention, if all '0', since no one is allowed to view the mode can not be viewed immediately step 5E Jump to).

As a result of checking in the above process, if neither "0" nor "1" is found, the password processing routine is performed (E).

That is, the previously stored limited age is loaded 1E and the bit corresponding to the loaded age is checked 2E. For example, if it is limited to a child's age, check bit b0.

If the bit b0 is '1', it branches directly to the viewable mode 5D and if the bit b0 is '0', the viewer is asked to input a password (3E).

Then, the user inputs the password inputted by the viewer against the stored password and checks (4E) whether the password is correct or not. By stopping viewing by issuing an off signal or the like, the performance of the method according to the invention is terminated.

As described above, the method of restricting the viewing of a specific program when watching television of the present invention is based on the input of a password upon reception of a specific program using information on the audience who can watch the television program of the EDS transmitted during caption / text broadcasting. By only allowing the children or children to watch the terrevision by protecting the youth and children from bad programs to prevent side effects due to the mass media, as well as preventing the random exposure of the adolescents to the media.
