Abstract:
An error correction code coding device for forming an error correction code by adding a check code for error code correction to input information codes, comprising:(a) first error correction code encoding means for forming a first error correction code by adding a first check code to each of first code groups sequentially input as a code sequence, the first code groups each having a first number of consecutive information codes; and(b) second error correction code encoding means for forming a second error correction code by adding a second check code to each of second groups, said second code groups each having a second number of information codes, each of the second code groups being formed by extracting a predeterminded number of information codes from the first code groups located at positions determined by skipping on a unit basis of N numbers of the first code groups, N being a natural number, said second error correction code encoding means including delay means for delaying a plurality of first code groups.
