Digital transmitter/receiver system having a robust error correction coding/decoding apparatus and a method error correction coding/decoding therof

The digital transmission / reception system and its error correction coding / correction method having strong error-correcting encoding apparatus. The transmitting side error correction encoding apparatus, adding a time division, and a parity of predetermined bytes to the data packet to split into N data packets, and (LN) parity packets for a field of data consisting of the L packets each claim has 1RS encoding unit, and a storage unit for storing the data packet the parity is added in a predetermined byte, and the stored data packets corresponding to the encoded 2RS generating parity packets to the section for. In response, the receiving side an error correction decoding apparatus, using each including a parity of predetermined bytes to the L packet and the 1RS decoding unit that corrects an error in the horizontal direction of the field data, for storing the error corrected data packets using the storage unit, and parity packet has claim 2RS decoding unit that corrects an error in the vertical direction of the field data. Therefore, it is possible to make more robust error correction by performing the error correction by using the parity is present in the horizontal and vertical directions with respect to the field data. Parity packet, vertical error correction, FEC, horizontal error correction
