Claims (1)

  1. 기록매체에서 재생된 재생신호의 시간축의 변동을 보정하는 동시에 드롭아웃을 수정하는 재생신호 회로에 있어서, 메인메모리와, 이 메인메모리에의 데이터 기입 및 독출을 제어하는 기입·독출 제어회로를 가지며, 상기 기입·독출 제어회로는 상기 메인메모리를 시분할적으로 제어함으로써, 상기 재생신호를 당해 재생신호와 동기해서 상기 메인메모리에 순차 기입하고, 또 상기 메인메모리의 기억데이터를 순차 소정의 일정주기로 독출하며, 또한 상기 메인메모리에 재생시신호를 기입할 때에 드롭아웃이 생겼을 때 당해 드롭아웃을 수정하는 것을 특징으로 하는 재생신호 보정회로.
    ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.
