제1도는 본 발명의 제1실시예에 있어서의 디지틀 VTR의 신호 처리방법의 블록도, 제4도는 본 발명에 따른 통상재생시의, 테이프로부터의 재생데이터, 은폐메모리의 출력 및 외부로 출력되는 피일드의 관계를 도시한 설명도, 제5도는 본 발명에 따른 저속 재생시의, 테이프로부터의 재생데이터, 은폐메모리의 출력 및 외부로 출력되는 피일드의 관계를 도시한 설명도.

Claims (5)

  1. m개의 피일드단위로 비트율감축부호화된 데이터를 n개의 기록블록으로 분활하여 삽입하고 기록하는 디지틀 VTR(비데오테이프레코오더)에 이용되는 신호처리방법에 있어서, 상기 n개의 기록블록을 n/m개식 작은 블록으로 분할하고, 저속재생시에 재생된 상기 기록블록을 상기 작은 블록단위로 검출하고, 상기 검출결과의 의거해서 1피일드 기간마다 출력되는 피일드를 제어하는 것을 특징으로 하는 디지틀 VTR의 신호처리방법.
  2. 제1항에 있어서, 저속재생시에 상기 작은 블록에 포함되는 기록블록의 재생의 종료가 검출되면, 그 다음 1피일드 기간에 출력되는 피일드를 절환하는 것을 특징으로 하는 디지틀 VTR의 신호처리방법.
  3. 제1항 또는 제2항에 있어서, 재생된 기록단위를 검출하여 기억하고 에러정정을 처리하는 제1메모리와, m개의 피일드 단위의 데이터를 1개의 피일드 단위의 데이터로 변환하여 출력하는 제2메모리를 구비하고, 상기 제1메모리의 출력을 상기 검출 결과에 의거하여 1피일드기간마다 상기 제2메모리에 기억하는 반면, 이와 동시에 제2메모리로부터의 출력 피일드를 절환하는 것을 특징으로 하는 디지틀 VTR의 신호처리방법.
  4. 제1항 또는 제2항에 있어서, 통상 재생시에는 출력피일드를 피일드기간마다 절환하는 것을 특징으로 하는 디지틀 VTR의 신호처리방법.
  5. 제1항 또는 제2항에 있어서, 역방향 재생시 상기 m개의 피일드를 정방향과 반대순서로 출력하도록 제어하는 것을 특징으로 하는 디지틀 VTR의 신호처리방법.
