ABSTRACT:
An error correction and/or detection device for product code block data, applied to a digital video tape recorder of a so-called D1 or D2 format, is disclosed, in which the correction mode of the correction by the outer codes is selected and the correlation between correction states of inner code corrected outer code blocks as well as the correlation of the correction states between the product code blocks are checked to lower the rate of correction or detection errors.
