Abstract

링크해야할 PCM 오디오 데이타의 시간축위의 위치를 확정할 수 있도록 링크처리의 신뢰성을 향상한다.
서브코드 구획정보 생성회로(6)에 있어서, 서브코드 동기검출회로(2)에선 검출한 서브코드 동기신호 s0/s1을 사용함과 함께, 서브코드 복조회로(4)에서 검출한서브코드중의 Q채널의 CRC 첵크정보 및 절대시간을 나타내는 프레임 번호에 의거해서 프레임 어드레스 발생회로(5)에서 발생되는 프레임 어드레스를 사용해서 서브코드 구획정보를 생성하여, 이 서브코드 구획정보에 대해서도 디지탈 오디오 데이타와 같이 에러검출 정정회로(7)를 통과시키므로서 TBC 처리를 실시한다.
