Abstract: A set of devices including: at least one receiver and at least one portable device, the receiver including a mechanism receiving a multichannel signal capable of preserving a part of the signal transmitted on a particular channel allowing information to be received, a conversion mechanism associated with a propagation mechanism broadcasting the information, and a communication mechanism; a portable object including an electronic module, the electronic module including at least a calculation unit and a wireless communication circuit to communicate with the communication mechanism of the receiver. The portable object can detect, via the wireless communication circuit, presence of at least one receiver belonging to the set of devices and acting on the at least one receiver to change the particular channel and to select a particular channel whose identifier or whose program currently being broadcast has at least one identifier identical to the identifier programmed in the portable object.
