Character Substitution Method on TV

The present invention relates to a method of replacing characters in television, and more particularly, to a method of replacing characters in television and video so as to replace pornographic and violent subtitle characters and sounds with purified standard subtitle characters and sounds. It is about.

In general, in a broadcasting system that provides an extended data service (EDS), for example, KBPS (Korea Broadcasting Program System) is a program for broadcasting programs and scheduled recording, and standard time data and viewing grades and captions. By converting the character information into a digital signal and inserting it into any one line of a video vertical blanking interval (VBI), this signal is demodulated by a KBPS decoder on the video receiving device side to reserve a broadcast program. You can perform functions such as recording and caption processing.

On the other hand, V (Violence) -CHIP has been developed to screen young people from watching programs that are pornographic, violent, or violent.

However, in the viewing restriction using the V-CHIP, there is a problem in that the output of the voice or text subtitles is blocked in order to restrict the viewing, and the output cannot be replaced with the purified voice or text subtitles corresponding to the viewing grade.

An object of the present invention is to store the purified word for the obscene or violent word on the TV to detect the obscene and violent subtitle character when receiving the broadcast signal and to replace the subtitle character of the stored purified word and to correspond to the subtitle character. The present invention provides a method of replacing characters in a television that generates a voice and converts and outputs the voice using a purified word.

A character substitution method in a television according to the present invention is a method for substituting and outputting obscene or violent characters with purified characters using caption character information inserted in predetermined horizontal lines within a vertical blanking period in a television. Detecting a caption character in the received broadcast signal; searching for whether the detected caption character is included in a prestored lewd or violent word; and detecting the caption character in a prestored lewd or violent word. And if included, reading the corresponding purified word and performing caption character processing with the read purified word.

In addition, when the caption content processing to the purified word, the purified word is converted into a voice, the lewd or violent voice is characterized in that the output is replaced by the purified voice.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

1 is a schematic block diagram of a television according to a preferred embodiment of the present invention, which includes a key input unit 10, a microcomputer 20, a tuner unit 30, an image signal processing unit 40, a character decoder 50, An OSD unit 60, a monitor 70, a standard language storage unit 80, a voice signal processing unit 90, a switch 100, and a speaker 110 are included.

In this configuration, the key input unit 10 is provided with a plurality of keys for performing the operation of the television outputs a key signal corresponding to the user's key operation, using a remote control that can normally be input from a remote location, The key signal carried on the infrared carrier from the detector is detected and output to the microcomputer 20 described later.

In addition, the microcomputer 20 controls the overall operation of the television based on the key signal from the key input unit 10, and in particular, the caption characters detected and applied from the character decoder 70 when the audio signal is output are stored in the standard language storage unit ( If the detected caption character is a word stored in the standard language storage unit 80, the corresponding purified word is searched in the standard language storage unit 80. The OSD unit 60 is read and controlled to replace the word with the purified word during character caption processing.

In addition, the microcomputer 20 outputs the purified word to the voice generator 120 to generate the purified word as a voice, and controls the switch 100 to produce a lewd or violent voice output from the voice signal processor 90. To control the output by switching to purified voice.

Meanwhile, the tuner unit 30 outputs a broadcast signal received by being tuned to a channel corresponding to the control from the microcomputer 20.

In addition, the video signal processor 40 separates the video signal from the broadcast signal from the tuner 30 under the control of the microcomputer 20, and processes the video signal into a displayable signal.

The character decoder 50 extracts caption character data inserted in a predetermined region of the vertical blanking period of the video signal separated from the broadcast signal from the tuner unit 30 and applies it to the microcomputer 20.

On the other hand, the OSD (On Screen Display) unit 60 reads the character font corresponding to the control of the microcomputer 20 and synthesizes the character signal to the image signal from the image signal processor 40 to output to the monitor 70. .

The standard language storage unit 80 stores obscene or violent words and purified words corresponding to the words, and outputs the stored words to the microcomputer 20 under the control of the microcomputer 20.

In addition, the voice signal processor 90 separates the voice signal from the broadcast signal from the tuner 30 and processes the voice signal into a signal that can be output.

On the other hand, under the control of the microcomputer 20, the switch 100 selectively switches the voice signal from the voice signal processor 90 or the voice signal from the voice generator 120, which will be described later, to be output to the speaker 110. do.
