Abstract

본 발명은 팔플러스(PAL+) 텔레비젼 수상기와 일반적인 브이씨알간의 인터페이스 기술에 관한 것으로, 일반적인 인터페이스회로에 있어서는 소정의 주파수상에 분포되어 있는 헬퍼신호를 디코딩할 수 없어 팔플러스 디코딩된 16:9 화면 비율의휘도신호/색신호 및 복합영상신호를 브이씨알에 공급할 수 없게 되고, 이로 인하여 일반 브이씨알에서 고화질의 16:9 영상을 녹화할 수 없게 되는 결함이 있었는 바, 본 발명은 이를 해결하기 위하여, 팔플러스 텔레비젼 수상기에서 팔플러스신호를 디코딩하여 16:9 화면용 휘도신호 및 색신호, 복합영상신호를 생성하고, 와이드 스크린시호의 검출여부에 따라16:9 화면용 영상신호나 4:3 화면용 영상신호를 선택하여 브이씨알측으로 출력하도록 하였다.The present invention relates to an interface technology between a PAL + television receiver and a general VLC. In a general interface circuit, a helper signal distributed over a predetermined frequency cannot be decoded. Since the luminance signal / color signal and the composite video signal cannot be supplied to the VRC, there is a defect that the high definition 16: 9 image cannot be recorded in the general VLC. Decodes the Arm Plus signal from a Plus TV receiver to produce luminance signals, color signals, and composite video signals for 16: 9 screens, and 16: 9 video signals or 4: 3 screen video signals, depending on whether widescreen signals are detected. Was selected to output to VRC side.
