This is achieved essentially by an improved scrambling and unscrambling method, whereby a message to be transmitted is recorded by means of a recording or read-in radiant energy beam upon the screen of a transmitting image storage tube and subsequently reproduced from the record track upon the screen of the tube by means of a read-out beam moved at a speed different from the speed of the read-in beam, in such a manner as to produce a coded or scrambled signal being transmitted to a receiving station either through wires or a wireless transmission link.
