Abstract

본 발명은 텔레비젼의 캡션모듈(CAPTION MODULE)에 관한 것으로, 특히 텔레비젼의 오디오/비디오 신호 출력에 현재의 데이타 형식으로 되어있는 캡션 신호를 복합 영상신호(COMPOSIT VIDEO)에 영상신호로 중첩시켜 출력하므로써 캡션기능이 내장되어 있지 않은 다른 텔레비젼의 화면에 캡션표시가 가능하게 하고, 녹화시에 영상신호 형태로 직접 녹화가 가능하도록한 캡션신호 변조 처리 모듈에 관한 것으로, 일체화된 캡션 코딩모듈을 구성하여 비디오신호에 캡션신호가 영상신호로 실려 있도록한 캡션신호 변조 처리모듈을 제공하고자 하는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caption module of a television. Particularly, a caption signal in the current data format is output to a composite video signal by overlapping it as a video signal on a television audio / video signal output. The present invention relates to a caption signal modulation processing module that enables caption display on another television screen that does not have a built-in function, and enables direct recording in the form of a video signal at the time of recording. An object of the present invention is to provide a caption signal modulation processing module in which a caption signal is loaded as an image signal.

Claims (1)

복합비디오 신호의 캡션방식을 인지하도록 한 정모다 동기신호에 수록되고 복합비디오 신호를 출력하도록한 버퍼부(80)와 비디오 신호 입출력수단, 메인처리부(30)와, 캡션 디코더(90)가 포함된 텔레비젼에 있어서, 상기 캡션디코더(30)로 부터 캡션디코더 출력신호를 칼라서브 캐리어로 변조하는 코딩변조부(100)와, 상기 코딩 변조된 칼라신호를 입력되는 수정, 수직 동기신호에 의해 조합시켜 복합크로마 형태로 출력토록 하는 복합크로마 출력부(110)와, 상기 복합크로마 출력부로 부터 출력된 신호를 마이콤의 제어신호와 수송버튼 수단에 의해 선택토록한 스위칭부(120)와, 버퍼부(80)를 통해 입력되는 복합비디오 신호, 상기 캡션디코더(90)로 부터 출력되는 휘도신호(Y), 상기 스위칭부(120)로 부터 입력된 복합크로마 형태의 신호를 가감하여 본래의 복합신호를 블랙레벨로 지정하여 주도록한 가감회로부(130), 비디오신호 출력부(62)로 입력신호를 전달하게 하는 버퍼(140)로 구성되는 것을 특징으로 하는 캡션신호 변조처리 모듈.A buffer unit 80, a video signal input / output means, a main processor 30, and a caption decoder 90 are included in the synchronizing signal to recognize the caption method of the composite video signal and output the composite video signal. In a television, a coding modulator 100 for modulating a caption decoder output signal from the caption decoder 30 into a color subcarrier, and combining the coded modulated color signal by an input correction and vertical synchronization signal are combined. A composite chroma output unit 110 for outputting in a chroma form, a switching unit 120 for selecting a signal output from the composite chroma output unit by a control signal and a transport button means of a microcomputer, and a buffer unit 80. The composite video signal input through the complex, the luminance signal (Y) output from the caption decoder 90, the complex chroma type signal input from the switching unit 120 is added to the original composite To give a black level by specifying a subtraction circuit 130, a caption signal modulation processing module, characterized in that consisting of a buffer 140 which forwards the input signal to a video signal output section (62) above. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
