Abstract
A coder converts M-bit information words into N-bit code words by generating a first and a second provisional code sequence using a coding rule by which, code words are logically assigned to information words so that a two's complement of a sum of coding bits included in the first provisional code sequence, is always different from a two's complement of a sum of coding bib included in the second provisional code sequence, when a first code state of the first sequence encoded starting from a predetermined original state is identical to a second code state of the second sequence encoded starting from said predetermined original state. Then, selecting either the first sequence or the second sequence depending on a value of at least one parameter that correlates with a DC content of the coded bit stream.
