Claims (3)
- 임의의 기준신호를 발생시키기 위한 기준신호 발생수단과 비디오 테이프에 기록되어 있는 캡스턴 모터 제어펄스를 검출하기 위한 제어펄스 검출수단을 구비하여 상기 제어펄스 검출수단의 검출신호를 상기 기준신호 발생수단의 기준신호와 비교하여 캡스턴 모터의 위상을 제어하는 위상제어회로에 있어서, 비디오 테이프 재생시 영상신호로부터 분리되는 수직 동기신호를 이용하여 캡스턴 모터 제어펄스를 발생시키는 제어펄스 발생수단과, 상기 제어펄스 검출수단의 제어펄스 검출 유/무에 따라 입력라인을 선택적으로 스위칭하여 제어펄스 검출수단의 출력신호와 제어펄스 발생수단의 출력신호중 어느 한 출력신호를 상기 기준신호 발생수단의 기준신호와 비교하여 캡스턴 모터의 위상 제어신호를 만들어 캡스턴 모터를 제어하는 위상 제어수단으로 구성함을 특징으로 하는 캡스턴 모터의 위상제어회로.
- 제1항에 있어서, 상기 제어펄스 발생수단은 영상신호로부터 분리되는 수직 동기신호를 1/2카운트하는 1/2주파수 카운터와, 상기 카운트 된 주파수신호를 미분하여 제어펄스를 만들어내는 미분기로 구성한 것을 특징으로 하는 캡스턴 모터의 위상제어회로.
- 제2항에 있어서, 상기 제어펄스 발생수단은 상기 1/2주파수 카운터를 통해 1/2카운트된 주파수 신호의 위상을 반전시키는 위상 반전기와, 상기 1/2주파수 카운터의 출력단자와 상기 위상반전기의 출력단자를 두 선택단자로 하여 무색신호시 스위칭되게 하는 제2선택 스위치를 구비함을 특징으로 하는 캡스턴 모터의 위상제어회로.
