Abstract

본 발명은 방송자막 메모리 기능을 갖는 티브이에 관한 것으로, 방송자막 정보 데이타를 저장하는 메모리를 별도로 구비하여 시청하던 프로가 끝난후 광고 시간에 방송자막 정보 데이타를 확인하게 하여 편리한 시청을 제공하는데 적당한 방송자막 메모리 기능을 갖는 티브이 제공하기 위한것이다.The present invention relates to a TV having a broadcasting subtitle memory function, and comprises a memory for storing the broadcasting subtitle information data. It is to provide TV with subtitle memory function.

이러한 방송자막 메모리를 갖는 티브이는 방송국에서 송출하는 방송 전파중 목적하는 방송국의 전파를 선국하는 튜너부와, 상기 튜너부에서 출력하는 IF 영상신호를 중폭하는 프리앰프부와, 상기 프리앰프부에서 중폭된 IF 영상신호를 원래의 방송 영상신호로 복조하는 복조부와, 상기 복조부에서 복조된 영상신호를 각각 휘도신호와 색신호로 분리처리하는 콤포지트 비디오부와, 상기 콤포지트 비디오부에 입력되는 영상신호에 따라 스위칭하는 스위칭부와, 상기 콤포지트 비디오부의 영상신호를 입력하여 휘도신호와 색신호로 합성하여 R.G.B원색 신호를 CRT로 출력하는 R.G.B매트릭스부와 상기 콤포지트 비디오부에 입력되는 영상신호중 방송자막 데이타를 필터링 하는 자막 필터부와, 상기 자막 필터부에서 출력되는 방송자막 데이타를 입력받아 저장하는 자막 메모리부와, 상기 전체 시스템을 제어하는 마이콤을 포함하여 구성됨을 특징으로한다.A TV having such a broadcasting subtitle memory includes a tuner unit for tuning radio waves of a desired station among broadcast radio waves transmitted from a broadcast station, a preamplifier unit for heavying an IF video signal output from the tuner unit, and a heavy width at the preamplifier unit. A demodulation section for demodulating the IF video signal into an original broadcast video signal, a composite video section for separately processing the video signal demodulated by the demodulation section into a luminance signal and a color signal, and a video signal input to the composite video section. Filtering the subtitle data of the RGB matrix unit for outputting the RGB primary color signal to the CRT by inputting the video signal of the composite video unit and the switching unit for switching according to the brightness signal and the color signal The caption filter unit and the broadcast caption data output from the caption filter unit are received and stored. It comprises a subtitle memory unit and a microcomputer to control the entire system.
