연속하는 PCM데이터를 (m×n)워어드의 단위로 블록화하고, 이 1블록내의 PCM 데이터의 각 워어드가 제1의 에러정정용의 장코오드의 생성계열과 제2의 에러정정용의 장코오드의 생성계열의 양자에 포함되며 또한 상기 1블록내의 PCM 데이터의 각 워어드의 상기 제1 및 제2의 에러정정용의 장코오드의 생성계열이 서로 상이하도록 이루어지고, 다시 상기 제1의 에러정정용의 장코오드의 생성계열에 상기 제2의 에러정정용의 장코오드가 포함되는 동시에, 상기 제2의 에러정정용의 장코오드의 생성계열에 상기 제1의 에러정정용의 장코오드가 포함되도록 하는 것을 특징으로 하는 에러정정부호화 방법Consecutive PCM data is blocked in units of (m × n) words, and each word of the PCM data in one block is used to generate a generation sequence of the long code for the first error correction and a long code for the second error correction. The generation sequence of the long codes for the first and second error correction of each word of the PCM data in the one block included in both of the generation sequences is made to be different from each other, and the first error correction chapter is again made. The generation code of the second error correction long code is included in the generation sequence of the code, and the error code characterized in that the generation code of the long code for the second error correction includes the long code for the first error correction. Corrective encoding method 상기 제1의 에러정정용의 장코오드 또는 상기 제2의 에러정정용의 장코오드의 초기값을 소정의 값으로 선정한 특허청구의 범위 1기재의 에러정정부호화 방법An error correction and encoding method according to claim 1 in which the initial value of the long code for the first error correction or the long code for the second error correction is selected as a predetermined value. 상기 소정의 값을 제어신호로 한 특허청구의 범위 2기재의 에러정정부호화 방법Error correction and encoding method according to claim 2, wherein the predetermined value is a control signal. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
