<p>A digital transmitter/receiver system having a strong error correction coding/decoding device and an error correction coding/decoding method thereof can guarantee a receiving performance even in an inferior channel environment. The error correction coding device for the digital transmitter system includes a time divider for dividing field data composed of L packets into N data packets and (L-N) parity packets, a first RS (Reed-Solomon) encoder for adding parities of a predetermined number of bytes to the data packets, respectively, a storage unit for storing the data packets having the parities of the predetermined number of bytes added thereto, and a second RS encoder for generating the parity packets corresponding to the stored data packets. Also, the error correction decoding device for the digital receiver system includes a first RS decoder for correcting errors in a horizontal direction of the field data using the parities of the predetermined number of bytes included in the L packets, a storage unit for storing the error-corrected data packets, and a second RS decoder for correcting errors in a vertical direction of the field data using the parity packets. Thus, the error correction can be strongly performed using the parities existing in the horizontal and vertical directions with respect to the field data.</p> |
