And an image processor 30 for performing image processing such as image intermediate frequency detection and amplification, and Y / C separation, an image output unit 40 for outputting an image to the CRT 50, and the CRT 50. In a projection television comprising a projection unit 60 for enlarging and projecting a projected television image, and a screen 70 for displaying an image enlarged and projected from the projection unit 60,

The V-Chip unit 80 for checking the grade of the television broadcast program received from the tuner unit 20 to output only the set grade, the memory unit 100 storing the password, and receiving and recognizing the voice. Voice recognition unit 110, a key input unit 130 for inputting a password, a password receiver 120 for receiving a password input from the key input unit 130, the voice recognition unit 110 and a password receiver ( And a micom 90 which controls to release the locking of the V-chip 80 when the voice and password received from the 120 are compared with the set values stored in the memory unit.

Referring to the viewing restriction function of the projection television, the V-Chip unit 80 receives the XDS data transmitted by being included in the program information of the television, compares the ratings, and outputs only the programs corresponding to the set ratings. Here, the XDS data included in the program information of the television is expressed by the class as shown in the following table using 3 bits of g0-g2 as an example.

g2 g1 g0 Rating FV V S L D 0 0 0 None * 0 0 One "TV-Y" 0 One 0 "TV-Y7" × 0 One One "TV-G" One 0 0 "TV-PG" × × × × One 0 One "TV-14" × × × × One One 0 "TV-MA" × × × One One One None *

The definition of the symbol shown in the above table is as follows.

FV: Pleasure / Violence

V: violence

S: Sexual thing

L: Adult

D: Obscene

TV-Y7: Target Programs 7 Years and Older

TV-G: common program

TV-PG: a bad program for children

TV-14: Unsuitable program for children under 14

TV-MA: Not suitable for ages 17 and under

As described above, the three bits of g0-g2 are combined with the broadcast program to create and provide data on the grade, and the receiving side receives the grade to select and view the grade.

In addition, the V-chip unit 80 includes a class comparison unit, a temporary storage unit, and a data detection unit, and in the example of the above grade, the user sets the viewable grade to "TV-14" and the key input unit 130 as described above. Input to store in the memory unit 100. If the ratings of the current broadcast programs detected from the data detector of the V-chipqn 80, which are not shown, are "TV-14" and "TV-MA", they are stored in the temporary storage unit. The grade comparison unit, which is not shown, receives data on the grade of the temporary storage unit and the grade of the memory unit 100, compares the grade, and outputs information on the comparison result.

The operation of the configuration of the present invention will be described in detail. When a user determines a grade of a program that a minor, such as a child, can view and stores it in the memory unit 100, the program of the grade can be freely watched because the password function is not given.

Password functions should be given to the remaining classes below the above level. In this method, the password is first inputted by voice. For example, if the password is set to "1234", when the user speaks "one, two, three, four" with voice, the voice recognition unit 110 voices the voice of the user and the one, two, three, The pronunciation of the word "sa" is recognized and stored.

In the state in which the password function is granted, the user must input the password to the voice recognition unit 100 by voice in order to watch a program below the permitted level. The voice recognition unit 100 compares the voice of the input voice with "one, two, three, four" with the stored password, and compares the input tone with the stored tone to determine whether the voice is identical. . When the voice passwords match, the corresponding signal is output to the microcomputer 90, and the microcomputer 90 releases the locking of the V-chip unit 80 so that the corresponding program can be displayed.

In addition, when only the voice password is used, the password may be easily leaked, and if a malfunction occurs in the voice recognition function of the voice recognition unit 100, the V-chip locking is released, thereby using the key input unit 130 together with the voice password. Enter the password directly. In this case, the V-chip locking is released only when the viewer inputs the voice password and simultaneously inputs the password using the key input unit.

As shown in FIG. 3, the method of the present invention includes a power-on process of turning on the projection television (S100) and a parental control program determining process of determining whether a broadcast program currently being received is a password-encoded program (S200). ) And a text and voice password input indication display process (S300) for displaying a message indicating OSD text input to input a text and voice password when it is determined that the password has been given as a parental control program (S300). If you enter the password confirmation process (S600) to compare the memory password (sound and tone) and compare the memory password, and if the voice password does not match, a message instructing to re-enter the voice password is displayed in OSD characters If the voice password re-entry indication display process (S700) matches the voice password, V-chip locking is performed. V-chip unlocking process (S900) to release, and the process of broadcasting the program.

In addition, when the voice password function and the key input password function are to be used together, a password input process of directly inputting a password to the password receiving unit of the projection television using the key input unit after the text and voice password input instruction display process (S300) (S400). ), And compares the input password with the stored password and performs the password verification process (S600). If the password is not matched, the password re-input instruction for displaying a message in OSD text indicating that the password is to be re-entered. The display process (S800) is to be further included.

4 is a flowchart illustrating an example of a process of limiting the number of password re-entry in the method of FIG. 3.

Password re-entry setting step (S410) for the user to set a password to enter the password re-entry limit using the key input unit, and (S410) for inputting the text and voice password, and the number of times the current password is entered and When the set value is exceeded by comparing the set value in step S410, the V-chip is locked, and when the set value is not exceeded, the step S420 is repeatedly performed.

According to the above method, in order for a viewer to watch an out-of-grade program, the user must enter a voice password and a text password to match the stored password so that the viewer can watch the program and limit the number of re-entry passwords to prevent the theft. Can be.

As described above, according to the present invention, when the power of the projection television is turned on while the password and the specific voice are stored in the projection television with the voice recognition function and the V-CHIP, the currently received program is restricted. A password is provided by granting a process of determining whether a program is granted, a message display process for instructing a password and voice input when it is determined to be a parental control program, a password and voice input process, a password and voice comparison process, and a V-chip locking release process. There is an effect that can effectively block minors' access to programs in which grades are granted.
