Description

오디오 데이터의 변속 재생처리 방식
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본원 발명에 관한 오디오데이터의 변속 재생처리방식을 디지털비디오 테이프 레코더에 적용하여 2배속 재생을 행하는 경우의 자기테이프상의 트랙포맷 및 다이나믹 트래킹헤드에 의한 주사상태의 일예를 나타내는 모식도.
제2도는 크로스페이드 처리를 실시한 재생오디오데이터를 나타내는 모식도.
제3도는 디지털비디오테이프 레코더에 사용하는 회전자기헤드 장치의 구성예를 나타내는 모식도.

Claims (1)

  1. 경사기록트랙을 분할한 기록영역에 트랙을 달리하여 동일 오디오 데이터를 2중 기록하고, 상기 경사기록트랙을 다이나믹 트래킹헤드로 주사하여 변속재생을 행함에 있어서, 트랙점프 전후의 재생 오디오데이터를 크로스 페이스(cross-fade)처리로 연결하는 것을 특징으로 하는 오디오데이터의 변속재생처리 방식.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
