ABSTRACT A method for digital transit-length for the transmission of binary coded picture information with redundancy reduction wherein short code words which frequently occur are assigned short transit lengths and wherein code words which rarely occur are assigned long transit lengths and wherein from a particular transit length a prefix word allows the differentiation of code words of the shorter transit lengths and a code word following the prefix word and indicating the respective transit lengths follows the prefix as a binary number. Black and white transit lengths which are transmitted as a single code word are associated with different code words where it is depending on how frequently they occur. The given transit length from which the coding is indicated with a prefix word is different for black and white transit lengths. An individual code word is transmitted at the beginning of the line and it differs from the code words for the individual transit lengths and from the word combination resulting from the prefix word and the subsequent code word and does not occur as a combination of bits of several words or partial words in the data flow to be transmitted.
