ABSTRACT:
In a interconnection assembly having two relays (R1,R2) for establishing a bi-directional wireless communication between two audio and/or video devices (4, 8) situated in different rooms (2, 3) in a building (1), a first one (4) of the two audio and/or video devices including a source (SAV) of audio and/or video electrical signals which can be controlled by means of a remote-control signal (6), the second (8) of the two audio and/or video devices including a receiver (TV2) and a remote control (TC) generating remote-control signals unable to pass through the walls of a building, one (R2) of the relays sending the remote-control information by radio link to the other relay (R1) which is able to return audio and/or video signals by radio link from the source (SAV) to the relay (R2), a coder (13) is provided for inserting a code in the remote-control information (9) and a decoder is provided (18) for decoding the coded remote-control information received by the relay (R1), comparing the code contained in the coded remote-control information with a reference code, and rejecting the decoded remote-control information in the event of non-agreement between the two codes.
