Two-dimensional error correcting method and decoder

U.S. Patent Number: 5386425

Abstract: A method carries out outer parity coding with respect to block identification data ID in a two-dimensional error correction method for adding an outer parity OP1 with respect to subblock data in the vertical direction and adding an inner parity IP with respect to either block identification data ID and subblock data or the block identification data ID and outer parity in the horizontal direction. Here, utilizing the recurrent pattern of the block identification data ID, the outer parity OP2 with respect to the block identification data ID is predictive-coded, and the outer parity decoding is performed along with the result of the predictive coding. Thus, the error correction effect with respect to the block identification data ID can be improved.
