Abstract
본 발명은 화면에 현재 수신되는 채널으 방송신호와 시청자가 원하는 다수 페이지의 문자방송을 동시에 출력시킬 수 있는 부화면 기능을 갖는 텔레비전에 관한 것이다.The present invention relates to a television having a sub picture function capable of simultaneously outputting a broadcast signal of a channel currently received on a screen and a character broadcast of a plurality of pages desired by a viewer.
본 발명은 텔레비젼 방송신호를 특정의 채널로 선국하는 제1튜너부와, 상기 제1튜너부의 출력신호를 증폭하는 프리앰프와, 상기 프리앰프의 출력신호에서 영상신호를 검출하여 복조하는 제1영상신호 처리부와, 상기 제1영상신호 처리부에서 복조된 영상신호를 디스플레이(display)시키는 CRT와 문자방송신호를 특정의 채널로선국하는 제2튜너부와, 상기 제2튜너부의 출력신호중 영상신호를 검출하여 복조하는 제2영상신호 처리부와, 상기 제2영상신호 처리부의 출력신호중에서 텔레텍스트를 디코딩하는 텔렉텍스트 디코더와, 상기 텔레텍스트 디코더의 동작을 제어하는 텔레텍스트 제어부와, 사용자에 의한 외부신호에 따라 시스템을 제어하는 마이컴과, 사이 마이컴의 제어신호에 따라 상기 텔렉텍스트 디코더에서 디코딩된 텔레텍스트신호를 상기 제1영상신호 처리부로 출력하는 PIP부를 포함하여 구성되는 것을 특징으로 한다.The present invention provides a first tuner unit for tuning a television broadcast signal to a specific channel, a preamplifier for amplifying an output signal of the first tuner unit, and a first image for detecting and demodulating a video signal from the output signal of the preamplifier. A signal processor, a CRT for displaying the video signal demodulated by the first video signal processor, a second tuner for tuning a character broadcast signal to a specific channel, and a video signal among the output signals of the second tuner A second video signal processor for demodulating, a teletext decoder for decoding teletext from an output signal of the second video signal processor, a teletext controller for controlling the operation of the teletext decoder, and an external signal by a user. And a teletext signal decoded by the teletext decoder according to a control signal of the microcomputer. Including PIP section for output to the signal processing unit is characterized in that configuration.
