Abstract
1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION
디지탈 VCR시스템에 있어서 인너코드 및 서브코드의 RS 디코더 신드롬 발생기 공유회로에 관한 것임.An RS decoder syndrome generator sharing circuit of inner code and sub code in a digital VCR system.
2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
디지탈 VCR이나 디지탈 캠코더에서 수신데이타의 에러정정시 인너코드 또는 시브코드의 RS 디코더 에러정정시에 신드롬 발생기를 공유하는 회로를 제공한다.Provided is a circuit for sharing a syndrome generator in error correction of an inner code or a sieve code in error correction of a received data in a digital VCR or a digital camcorder.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
디지탈 브이씨알 시스템에 있어서 인너코드 및 서브코드의 알에스 디코더 신드롬 발생기 공유회로는, 수신데이타를 입력으로 서브코드 및 인터코드시 α=1 값을 하기의 계산식을 이용하여 신드롬 S0를 발생하는 제1수단과, 상기 수신데이타를 입력으로 서브코드시에는 GF(24)의 α1, α2, α3값을 선택하고 인너코드시에는 GF(28)의 α1, α2, α3가 곱해진 값을 선택하여 하기의 계산식을 이용하여 신드롬 S1∼S3를 발생하는 제2수단과, 상기 수신데이타를 입력으로 인너코드시에만 GF(28)의 α1, α2, α3값을 하기의 계산식을 이용하여 신드롬 S4-S7을 발생하는 제3수단으로 구성한다.In the digital VLC system, the inner decoder and subcode RS decoder syndrome generator sharing circuit generates a syndrome S0 by using the following calculation equation with α = 1 value at the time of subcode and intercode with the received data as input. when the sub-code as input means, and the received data, the selection of α 1, α 2, α 3 value of GF (2 4), and α 1, α 2, α 3 of, the GF (2 8) when the inner code A second means for generating syndromes S1 to S3 by selecting the multiplied value and using the following formula and inputting the received data to the α 1 , α 2 , α 3 value of GF (2 8 ) only at inner code. A third means for generating syndrome S4-S7 is constructed using the following calculation formula.
여기서, 5,=신드롬(j=0∼2t-1), r(x) : 수신데이타(x=α0∼α2t-1)Where 5, = syndrome (j = 0 to 2t-1 ), r (x): reception data (x = α 0 to α 2t-1 )
4. 발명의 중요한 용도4. Important uses of the invention
디지탈 VCR 또는 디지탈 캠코더에서의 에러정정 기술에 사용된다.Used in error correction techniques in digital VCRs or digital camcorders.
