Abstract
The invention relates to a method of converting a stream of databits of a binary information signal into a stream of databits of a constrained binary channel signal. This stream of databits of the binary information signal is divided into n-bit information words. These information words are converted into m-bit channel words, in accordance with a channel code C, or m-bit channel words, in accordance with a channel code C, where m, mand n are integers for which it holds that m>m≧n. The m-bit channel word is chosen from of at least two m-bit channel words, at least two of which have opposite parities, the concatenated m-bit channel words and the m-bit channel words complying with a runlength constraint of the binary channel signal. The method comprises the repetitive and/or alternate steps of: The invention further relates to a device for encoding, a signal comprising a stream of databits of a constrained binary channel signal, a record carrier and a device for decoding.
