- 제1의 배열상태에서의 여러개의 디지탈심볼(0j,1j,..,9j)와제1의 패리티 심볼(12A,.. A1j,A2j)를 포함하는 제1의 에러검출 및 에러정정코드워드와 상기 제1의 에러검출 및 에러정정코드워드의 심볼을 갖는 제2의 배열상태에서의 여러개의 디지탈 심볼(i0,i1,...,i9)와 제2의 패리티 심볼(12B,Bk0,Bk1)을 포함하는 제2의 에러검출 및 에러정정코드워드를 정정하기 위한 코드에러정정방법에 있어서, 상기 제2의 패리티 심볼(12B)를 이용하여 에러검출 또는 에러정정을 실행하는 스텝(스텝 1)과 상기 제1의 패리티 심볼을 이용하여 상기 제1의 에러검출 및 정정코드워드에 포함된 에러가 순차로 발생하는지 않하는지를 판정하고(스텝 2), 이 판정의 결과에 따라서 상기 제1의 에러검출 및 정정코드워드내의 에러가 순차로 발생한다고 판정되면 적어도 2가지형의 에러정정방식의 첫번째 것으로, 또는 상기 제1의 에러검출 및 에러정정코드워드내의 에러가 순차로 발생하지 않는다고 판정되면 상기 적어도 2가지형의 에러정정방식의 두변째 것으로 전환하는 스텝(스텝 3,5)를 포함하는 코드에러정정방법.
- 특허정구의 범위 제1항에 있어서, 상기 제1의 에러검출 및 에러정정코드워드의 상기 적어도 2가지형의 에러정정방식의 상기 첫번째 것은 삭제정정방식인 코드에러정정방법.
- 특허청구의 범위 제1항에 있어서, 상기 2가지형의 에러정정방식은 랜덤에러정정방식과 삭제정정방식인 코드에러정정방법.
- 특허청구의 범위 제 1항에 있어서, 상기 전환하는 스텝은 또 상기 제 1의 에러검출 및 에러정정코드워드내의 에러가 순차로 발생한다고 판정될 때 삭제정정방식으로 전환하는 스텝과 상기 제1의 에러검출 및 정정코드워드내의 에러가 랜덤하게 발생한다고 판정될때 랜덤에러정정방식으로 전환하는 스텝을 포함하는 코드에러정정방법.
- 특허청구의 범위 제4항에 있어서, 상기 제l 및 제2의 배열에서의 상기 여러개의 디지탈심볼은 각각이중 엔코딩방식의 수직열 및 수평행에 대응하고, 상기 랜덤에러정정방식은 수직랜덤에러정정회로이며, 상기 삭제정정방식은 수직삭제정정회로인 코드에러정정방법.
