ABSTRACT An encoding method for error correction whereby redundancy data for error detection or error correction is added regarding each of one direction and the other direction of digital informa- tion data in which a plurality of blocks each consisting of a plurality of symbols are arranged, the encoding method comprising the steps of: allowing a code sequence of at least an error detectable first error detection code which is applied to the encoding in the one direction to exist in some plurality of blocks among the plurality of blocks; forming a code sequence of a second error correction code in the other direction by the plurality of symbols which are respectively included in different code sequences of the first error detection codes; and sequen- tially transmitting the blocks which consist of the symbols of the digital information data and the redundancy data of the first error detection code and the blocks which consist of the redun- dancy data of the second error correction code and the redun- dancy data of the first error detection code.
