Abstract:
A Reed-Solomon encoding device that can handle multiple RS (Reed-Solomon) codes by means of different field generation polynomials, comprising:a first Galois field transformation means that transforms source data into a specified Galois field on the basis of a first Galois field transformation parameter; an encoding means that performs encoding processing using a selected multiplication coefficient set for the aforementioned transformed source data by means of the aforementioned Galois field after transformation; a second Galois field transformation means that performs an inverse transform of the encoded data on the basis of a second Galois field transformation parameter; and a parameter output means that outputs the first Galois field transformation parameter, the second Galois field transformation parameter, and the selected multiplication coefficient set, wherein the parameter output means is operable to be loaded with transformation parameters and multiplication coefficients selected from a plurality of transformation parameters and multiplication coefficients.
