Claims (3)

  1. 정보심볼에 기준한 신드롬을 계산하여 부호화 및 복호화 하는 방법에 있어서 단축화 부호에 있어 정보심볼이 전부 "0"의 정보를 부호화한 때 체크 심볼부가 "0"이 되지 않도록 어느 약속된 "0"이 아닌 정수를 정보심볼 계열에 부가하여 부호화 및 복호화를 실행하는 것을 특징으로 하는 부호화 복호화 방법.
  2. 제1항에 있어서 단축화 부호는 FG(2b)의 리드 솔로몬 부호일 것을 특징으로 하는 부호화 복호화 방법.
  3. 제1항에 있어서, 신드롬을 계산할 경우 프리세트 기능을 가진 신드롬 계산용 래지스터를 사용하여 상기 신드롬 계산용 래지스터가 "0"이 아닌 상태에서 신드롬 계산을 하여 부호화 및 복호화를 하는 것을 특징으로 하는 부호화 복호화 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
