Abstract

본 발명은 화면에 출력되는 텔리텍스트(teletext)를 음성으로 출력시킬 수 있는 문자방송 텔레비전에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character broadcasting television capable of outputting teletext output on a screen as voice.

본 발명은 튜너부와,음성신호를 검출하여 복조하는 음성신호 처리부와,음성신호를 증폭하여 스피커로 출력하는 사운드앰프와, 상기 튜너부의 출력신호를 증폭하는 프리앰프와,영상신호를 검출하여 복조하는 영상신호 처리부와,영상신호를 디스플레이시키는 CRT와,영상신호 중에서 텔레텍스트를 디코딩하는 텔레텍스트 디코더와, 외부신호에 따라 시스템을 제어하는 마이컴과,텔레텍스트를 판독하는 문자판독부와,판독된 문자를 저장하는 순간문자 메모리부와,상기 판독된 문자를 순차적으로 리딩(reading)하는 순차리딩부와, 상기 순차리딩부의 출력신호를 음성신호로 변환시켜 상기 사운드앰프로 출력시키는 자막음성 출력부를 포함하여 구성되어 시각장애자 및 문맹자에게 정보를 용이하게 제공할 수 있는 효과가 있는 것을 특징으로 한다.The present invention provides a tuner unit, a voice signal processing unit for detecting and demodulating a voice signal, a sound amplifier for amplifying the audio signal and outputting it to a speaker, a preamplifier for amplifying the output signal of the tuner unit, and detecting and demodulating a video signal. A video signal processor, a CRT for displaying a video signal, a teletext decoder for decoding teletext from a video signal, a microcomputer for controlling the system according to an external signal, a character reader for reading teletext, and a read character An instantaneous character memory unit for storing the sequential characters, a sequential reading unit for sequentially reading the read characters, and a caption audio output unit for converting an output signal of the sequential reading unit into a voice signal and outputting the audio signal to the sound amplifier; It is configured to have an effect that can easily provide information to the blind and illiterate.
