<p>A decoding apparatus in which for a plurality of symbols arranged in a matrix fashion first and second error correction codes are encoded for each of the plurality of symbols respectively arranged in a first direction and in a second direction and in which input data are transmitted in the first direction. The decoding apparatus includes a first memory (40) for writing input data, an error detector (36) for detecting an error of the input data that are written into the first memory (40) based on the first error correcting code and for generating error data from the first error correction code. A second memory (40) is provided for writing error data of the first error correction code and an error corrector (41) is provided for sequentially executing error corrections of the first and second error correction codes for the input data that are written into the first memory (40) by using the error data of the first error correction code that are written into the second memory (40).</p> |
