The invention relates to a method of decoding possibly mutilated codewords (r) of a code (C) into information words (m') comprising information symbols (m'1, m'2, . . . ,m'k), said information words (m) being encoded into codewords (c) of said code (C). In order to provide a method and apparatus for decoding such a code without the need to considerably deviate from the standard method and apparatus for decoding a standard Reed-Solomon code, a method of decoding is proposed according to the present invention, comprising the steps of: decoding said possibly mutilated codewords (r) into codewords (r')', reconstructing information symbols (m'1, m'2, . . . ,m'k) from said codewords (r'), comparing said reconstruct information symbols (m'1, m'2, . . . ,m'k) with information symbols (m1) known a priori before decoding, and verifying decoding errors based on the result of said comparison.
