Description

칼라텔레비전용 결함보상회로
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 칼라텔레비전 시스템에 적용할 수 있는 결함보상회로의 개략도(계통도). 제2도는 제1도의 시스템을 더욱 상세히 도시한 개략도(부분적인 계통도). 제3도 및 제4도는 지연신호와 전류비데오 신호간의 dc성분 내에 불필요한 차등을 제거하기 위한 장치를 포함하며 본 발명을 실시한 결함보상회로의 개략도(블록형태)

Claims (1)

  1. 본문에 설명하고 도면에 도시된 바와 같이, 규정된 시간후에 지연신호를 제공하도록 실시간 신호에 반응하여 배열된 신호 지연장치와, 제1 및 제2제어신호를 각각 발생시키기 위해 상기 실사간 신호의 신호결함 유무에 반응하는 결함 검출장치와, 상기 출력단자에 실시간신호를 인가시키기 위해 상기 제1제어신호에 반응하고 상기 출력단자에 지연신호를 인가시키기 위해 상기 제2제어신호에 반응하는 제1스위치장치 및 출력단자를 포함하는 실시간 신호결함에 대한 지연신호를 대치시키는 형태의 결함 보상회로에 있어서, 상기 출력단자에서 dc성분의 불필요한 전이를 피하기 위한 장치와, 상기 제1제어신호 동안 상기 출력단자에 인가된 실시간 신호의 dc성분을 추적 및 지지시키기 위한 그리고 상기 제2제어신호 동안 지연신호의 dc성분을 배제하도록 상기 출력단자에 이 dc성분이 인가되도록 지속되기 위한 장치를 포함하는 개량된 장치를 특징으로 하는 칼라텔레비전용 결함보상회로.
