제6도 (가) (나)는 제5도에 의해 처리되는 데이타의 구성도.6 (a) and (b) are diagrams of the data processed by FIG.

Claims (1)

입력데이타 소정갯수(K)의 심볼에 대한 에러정정능력을 갖는 패리티를 부가하여 전송되는 데이터의 에러정정방식에 있어서, 횡방향 복호시 K심볼미만의 에러에 대해서는 에러포인터를 부가하지 않고 에러를 정정하며 K심볼이상의 에러에 대하여는 1차복호를 통해 K심볼까지의 에러에 대하여 정정을 하고 다시 신드롬을 연산하여 모든 신드롬이 “0”인 경우에는 에러포인터를 부가하지 않고 종방향에 대한 복호를 수행하며 상기 신드롬중 하나라도 “0”이 아니면 정정능력이상의 에러가 발생한 것으로 판정하여 정정전의 데이터에 에러포인터를 부가하여 종방향의 복호에 대한 소실정정능력을 향상시키는 것을 특징으로 하는 압축데이타의 에러정정방식.In the error correction method of data transmitted by adding a parity having error correction capability for a predetermined number of symbols of input data, the error is corrected without adding an error pointer for errors less than K symbols in the horizontal decoding. In case of error above K symbol, the error from K symbol is corrected through the first decoding, and the syndrome is calculated again. When all syndromes are “0”, the decoding in the longitudinal direction is performed without adding an error pointer. If any one of the syndromes is not "0", it is determined that an error of correcting capability has occurred, and an error pointer is added to the data before correction to improve the loss correcting ability for longitudinal decoding. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
