"PROCESS TO CONVERT A DATA BITS FLOW FROM A BINARY INFORMATION SIGNAL TO A RESTRICTED BINARY CHANNEL DATA BITS, APPLIANCE FOR CODING A BINARY INFORMATION SIGNAL DATA BITS RESTRICTED BINARY CHANNEL SIGNAL DATA BITS SIGNAL, RECORDING CARRIER, AND PROCESS AND APPARATUS TO DECODE A RESTRICTED BINARY CHANNEL SIGNAL FLOW ON A BINARY INFORMATION SIGNAL BITCH ". The invention relates to a process for converting a data bit stream of a binary information signal into a data bit stream of a restricted binary channel signal, this signal being constructed repeatedly or alternately using a C channel code. ~ 1 ~ and a C ~ 2 ~ channel code. Because two channel words with opposite parities are available in the C ~ 2 ~ channel code for each information word, and for the same state to be established, predetermined properties of the restricted binary channel signal may be influenced, e.g. eg to perform guaranteed DC control, ie independent of the data bit stream content of the binary information signal. Because the process further comprises the step of substituting, depending on a value of a predetermined property of the binary channel signal, a channel word for a substitute channel word, in which the substituted channel word and the word substitute channels establish the same state, predetermined properties of the restricted binary channel signal may still be influenced. The invention further relates to an apparatus for encoding, a signal, a recording carrier, a decoding process and an apparatus for decoding.
