Abstract

본 발명은 방송자막 메모리 기능을 갖는 티브이에 관한 것으로, 한 화면상에 동시에 2중 자막이 디스플레이 될 경우에 있어서, 2차 자막을 메모에 저장하였다가 리플레이시켜 시청자들에게 정확한 정보 전달 및 편리성을 제공하는데 적당한 방송자막 메모리 기능을 갖는 티브이 제공하기 위한 것이다.The present invention relates to a TV having a broadcasting subtitle memory function, and when two subtitles are simultaneously displayed on one screen, the secondary subtitles are stored in a memo and replayed to provide accurate information and convenience to viewers. To provide a TV having an appropriate broadcast subtitle memory function.

이러한 방송자막 메모리를 갖는 티브이는 사용자의 요구에 따라 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 연결되어 영상 신호중 자막의 유무 및 2중자막의 유무를 검색하는 자막 및 2중 자막 검색부와, 상기 2중 자막이 포함된 영상 신호중 2차 자막만을 여과하는 자막 필터부와, 상기 자막 필터부에서 출력하는 자막정보를 저장하는 자막 메모리부와, 상기 자막 메모리부에 저장된 자막 정보의 출력 및 전체시스템을 제어하는 마이콤을 포함하여 구성됨을 특징으로 한다.A TV having such a broadcasting subtitle memory includes a tuner unit for tuning radio waves of a desired broadcasting station according to a user's request, a preamplifier unit for amplifying an IF video signal output from the tuner unit, and an IF amplified by the preamplifier unit. Demodulation unit for demodulating the video signal into the original broadcast video signal, a composite video unit for separating and processing the video signal demodulated by the demodulation unit into a luminance signal and a color signal, respectively, and the presence or absence of subtitles in the video signal And a subtitle and double subtitle searching unit searching for the presence or absence of a double subtitle, a subtitle filter unit filtering only secondary subtitles of the image signal including the double subtitles, and storing subtitle information output from the subtitle filter unit. And a micom for controlling the output of the subtitle information stored in the subtitle memory and the entire system. The.
