摘要：
A method of converting a stream of databits of a binary information signal into a stream of databits of a constrained binary channel signal, a device for encoding, a signal, a record carrier, a method for decoding, and a device for decoding. The signal is constructed by repetitively or alternately using channel codes C1 and C2. Since two channel words with opposite parities are available in the channel code C2 for each information word, and the same state is established, predetermined properties of the constrained binary channel signal can be influenced. Since the method further comprises the step of substituting, in dependence upon a value of a predetermined property of the binary channel signal, a channel word for a substitute channel word, wherein the substituted channel word and the substitute channel word establish the same state, predetermined properties of the constrained binary channel signal can be further influenced.
