<p>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.</p> |
