ABSTRACT:
An apparatus and method for error correction which interleaves by inner codes two fields in one frame during product-coding which is used to correct burst errors, so as to disperse the errors through the two fields (that is, to at least double the correction ability), thereby preventing the deterioration of picture quality which is caused by the errors being restricted to one field when the burst errors occur. Further, the apparatus and method reduce the deterioration of picture quality by smoothly performing a function of error concealment by preventing error concentration even when the errors occur outside the range of error correction ability.
