Device for selectively receiving data broadcast simultaneously to a predetermined subset of recipient devices from among massive quantities of receivers which are capable of physically receiving the data which are broadcast by radio or by power-line communication in a telecommunications network or in a digital signal broadcasting network, comprising: - at least one digital processing subassembly comprising at least one microprocessor, at least one program memory; - a low-voltage power supply subassembly providing at least one direct voltage to power the hardware means of the device, said power supply subassembly being powered by at least one energy source; said device being characterized in that it further comprises: - first means for receiving at least one configuration data usable for limiting the effective reception of the broadcast data to only the previously determined devices, the at least one configuration data being transmitted within the framework of a point-to-point link between at least one remote information system and the device; - second means for receiving broadcast data including data determining the selectivity of the broadcast; - the at least one digital processing subassembly further comprising an interface with said first means, an interface with said second means, an interface with means for using data received by said second means, at least one memory for storing all or part of the at least one configuration data or at least one broadcast transmitter identifier, at least one program for determining whether received broadcast data should be used or ignored by the device as a function of said data determining the selectivity of the broadcast, and of all or part of the at least one data having been previously stored in the at least one memory. - at least one digital processing subassembly comprising at least one microprocessor, at least one program memory; - a low-voltage power supply subassembly providing at least one direct voltage to power the hardware means of the device, said power supply subassembly being powered by at least one energy source; said device being characterized in that it further comprises: - first means for receiving at least one configuration data usable for limiting the effective reception of the broadcast data to only the previously determined devices, the at least one configuration data being transmitted within the framework of a point-to-point link between at least one remote information system and the device; - second means for receiving broadcast data including data determining the selectivity of the broadcast; - the at least one digital processing subassembly further comprising an interface with said first means, an interface with said second means, an interface with means for using data received by said second means, at least one memory for storing all or part of the at least one configuration data or at least one broadcast transmitter identifier, at least one program for determining whether received broadcast data should be used or ignored by the device as a function of said data determining the selectivity of the broadcast, and of all or part of the at least one data having been previously stored in the at least one memory. - first means for receiving at least one configuration data usable for limiting the effective reception of the broadcast data to only the previously determined devices, the at least one configuration data being transmitted within the framework of a point-to-point link between at least one remote information system and the device; - second means for receiving broadcast data including data determining the selectivity of the broadcast; - the at least one digital processing subassembly further comprising an interface with said first means, an interface with said second means, an interface with means for using data received by said second means, at least one memory for storing all or part of the at least one configuration data or at least one broadcast transmitter identifier, at least one program for determining whether received broadcast data should be used or ignored by the device as a function of said data determining the selectivity of the broadcast, and of all or part of the at least one data having been previously stored in the at least one memory.
