Claims (2)
- 주문형 비디오 시스템에서 소정 비트의 동기 신호, ID 신호, 비디오 데이타 신호, 패리티 신호로 이루어진 다수의 동기 블럭을 포함하는 디지탈 데이타 스트림 재생시 상기 동기 블럭내의 동기 신호의 에러에 기인하여 발생되는 데이타 손실을 복원하기 위한 방법으로서, 입력되는 상기 디지탈 데이타 스트림에서 동기 신호를 검출 비교하여 동기 신호가 검출되면 입력되는 동기 블럭 데이타를 동기 블럭 단위로 재생 처리하는 제1과정과; 동기 신호가 검출되지 않으면 입력되는 동기 블럭 데이타를 메모리에 순차적으로 저장하고 다음 동기 블럭의 동기 신호가 검출되는지를 판단하는 제2과정과; 다음 동기 블럭의 동기 신호가 검출되면 동기 신호가 검출되지 않아서 상기 메모리에 저장되어 있는 데이타의 에러를 복원하여 처리하는 제3과정을 포함하는 주문형 비디오 시스템에서의 데이타 에러 복원 방법.
- 제1항에 있어서, 상기 제3과정은 상기 메모리에 저장되어 있는 데이타를 LIFO(Last In First Out) 방식으로 소정 비트까지 카운트하면서 스캐닝하여 ID 신호를 확인하는 과정과; ID 신호가 확인되면 ID 신호가 확인된 동기 블럭을 상기 메모리에서 출력하여 재생 처리하고 ID 신호가 확인이 안되면 상기 메모리를 클리어시키는 과정을 포함하는 것을 특징으로 하는 주문형 비디오 시스템에서의 데이타 에러 복원 방법.
