PHN 10.444 11 29.9.1982, ABSTRACT:, Method of encoding a stream of data bits device for, carrying out the method, and device for decoding a stream of data bits. The invention relates to a method of encoding a stream of data bits of a binary source-signal into a stream of data bits of a binary channel-signal. The stream of data bits of the source signal is divided into a sequence of five permissible source words of variable length. Each of these five permissible source words is converted into a channel word with twice the number of data bits. This conversion has been selected in such a way that the error propagation is very small and, moreover the, electronics can be very simple.
