Abstract
A Reed-Solomon encoding device is provided that can handle multiple RS (Reed-Solomon) codes using different field generation polynomials. The encoding device uses a first Galois field transformation that transforms source data into a specified Galois field on the basis of a first Galois field transformation parameter. The transformed source data is received by an encoder that performs encoding processing using a selected multiplication coefficient set. A second Galois field transformation is used for performing an inverse transform of the encoded data on the basis of a second Galois field transformation parameter. A parameter output is used for outputting the first Galois field transformation parameter, the second Galois field transformation parameter, and the selected multiplication coefficient set. The parameter output generator is operable to be loaded with transformation parameters and multiplication coefficients selected from a plurality of transformation parameters and multiplication coefficients.
