ABSTRACT:
An interface is made for a device for the exploitation of electrical signals between a receiver of this device and a device for the exploitation of these signals. The interface is capable of sending, alternatively, signals received by the receiver to an external circuit and signals delivered by the external circuit to the exploitation circuit. It is shown that this approach can be used to resolve problems of the scrambling and unscrambling of audio-visual signals.
