Abstract
A method and apparatus are described for transmitting, over switching apparatus, digital information signals, together with a preceding address signal, wherein the address signal indicates a signal receiver capable of receiving the information signals in any time sequence. The information signals emanating from a given signal transmitter, prior to being transmitted to the switching apparatus, are individually stored, and only after a predetermined number of information signals are present are the information signals and related address signals transmitted. In the switching apparatus the address signal is used to establish a connection between the switching apparatus input and the switching apparatus output connected to the addressed signal receiver only for the period during which the information signals are transmitted.
