Abstract

본 발명은 브이씨알과 텔레비젼수상기의 팔플러스신호 인터페이스 기술에 관한 것으로, 일반적인 팔플러스 브이씨알에서 복합영상신호(CVBS)를 휘도(Y)/색신호(C)분리시 색신호 경로에서 수직 헬퍼신호의 주파수에 손상을 주게되고, 분리된 휘도/색신호를 팔플러스 텔레비젼수상기에서 입력받게 되면 컬러플러스를 실행하지 못해 컬러성분에 휘도성분의 노이즈가 혼입되어 컬러부분의 화질이 떨어지는 문제점이 있었는 바, 본 발명은 이를 해결하기 위하여 팔플러스 브이씨알과 텔레비젼수상기간의 영상신호인터페이스에 있어서 녹화시에는 헬퍼신호를 휘도영역에 기록하고 재생시 그 헬퍼신호를 추출하여 색신호경로로 전송하도록 하였다.The present invention relates to an arm plus signal interface technology of a television and a television receiver, wherein the frequency of the vertical helper signal in the color signal path when the complex video signal (CVBS) is separated from the luminance (Y) / color signal (C) in a general Palm Plus VR. When a separate luminance / color signal is received from a Palm Plus TV receiver, color plus cannot be executed, and noise of luminance component is mixed into color components, thereby degrading the image quality of the color portion. In order to solve this problem, in the video signal interface between the FalPlus V and the television receiver, the helper signal is recorded in the luminance region during recording, and the helper signal is extracted during reproduction and transmitted to the color signal path.
