Abstract
There are provided a Reed Solomon coding apparatus and a Reed Solomon coding method which are capable of performing a Reed Solomon coding process in a way adapted to case where a primitive polynomial, a generator polynomial, and a number of errors to be corrected are changed. The apparatus comprises a generator polynomial coefficient generation block which receives a primitive polynomial set value and a generator initial value as inputs, expands the generator polynomial to generate coefficient data using these values, and a data coding block which receives the primitive polynomial set value and divides an information polynomial by the generator polynomial using the value , thereby coding data.
