Abstract

본 발명은 프로덕트 리드-솔로몬 코드(Product Reed-Solomon)를 사용하여 디지탈 브이씨알의 에러정정장치 및 방법에 관한 것으로, 특히 내부코드(inner code)와 외부코드(outer code)를 하나의 엔코더/디코더로 에러정정을 수행할 수 있도록 하는 디지탈 브이씨알의 에러정정장치 및 방법에 관한 것으로, 종래 디지탈 브이씨알의 프로덕트 리드-솔로몬 코드의 에러 정정기능을 수행하기 위해서는 각2개의 내부코드와 외부코드의 엔코더와 디코더가 필요로 하게되어 회로 면적의 증가와 이에 따른 원가상승의 문제점이 있었으나, 본 발명에서는 하나의 엔코더/디코더를 사용하여 내부 엔코딩/디코딩을 하지 않는 사이사이에 외부 엔코딩/디코딩을 수행함으로써 하드웨어의 크기를 줄이는 효과와 그에 따른 비용절감의 효과도 있게 된다.The present invention relates to an apparatus and method for error correction of a digital VHS using a product Reed-Solomon code. More particularly, the present invention relates to an apparatus and method for error correction of a digital VHS, In order to perform the error correction function of the product Reed-Solomon code of the digital V-Codel, it is necessary to perform an error correction of each of the two internal codes and the encoder of the external code However, in the present invention, external encode / decode is performed between internal encoders / decoders without using an encoder / decoder, so that hardware It is possible to reduce the size and cost of the apparatus.
