It is known to transmit additional information in a digital data transmission system by means of the change between two codes in which a main information is transmitted. According to the invention, the additional information (Z) is transmitted by virtue of the fact that the code for the main information (H) is switched over from a first to a second code for a first period of time with one binary value of the additional information (Z) and for a second period of time with the other binary value. <IMAGE> |
