method for processing signals which are useful in a system videocitofonico and videocitofonico system which implements this method.

摘要

a method is described for processing signals which are useful in a system videocitofonico or similar, said system comprising several devices (c, m) are interconnected by means of two wires (i,i); the main feature of the method lies in the fact that in order to obtain the benefits taken with the use of only two wires.transmission techniques are used for the different signals from different transmit overlapping (call, video, audio, external - internal, internal audio - outside, buzzer)and that means of encoding and decoding are provided to make it possible, in spite of this overlap, the operation of the system.
