Device, system and method for selectively receiving data broadcast in a network

A device for selectively receiving a data broadcast, to be received simultaneously by a plurality of devices belonging to a predetermined sub-assembly of receiving devices among receiving devices capable of physically receiving data transmitted from a remote information system through a wide-area telecommunication network and/or through a wide-area digital signal broadcast network, the device comprising:

• first and second receiving means,
• said first receiving means configured to receive at least one configuration datum for limiting an effective reception of application data by said second receiving means, said at least one configuration datum being transmitted by a remote information system through a wide-area telecommunication network in the framework of a point-to-point connection, and
• said second receiving means configured to receive a broadcast of data via wide-area radio and/or wide-area power-line communication, transmitted by at least one transmitter belonging to a wide-area telecommunication network infrastructure and/or belonging to a wide-area digital signal broadcast network infrastructure, the data comprising said application data and data determining a selectivity of the broadcast;
• at least one digital processing sub-assembly comprising at least one microprocessor, at least one program memory, an interface with said first means, an interface with said second means, and a hardware and/or software interface with means for using all or part of the application data received by said second receiving means;
• at least one memory for storing all or part of the at least one configuration datum and/or of at least one broadcast transmitter identifier;
• a low-voltage power supply sub-assembly for supplying at least one direct voltage to the device, said supply sub-assembly being supplied by at least one source of energy;
• and
• at least one program, stored in the program memory, that upon execution by the at least one microprocessor causes the at least one microprocessor to operably determine whether all or part of the application data received by said second receiving means is either used or ignored by the device, according to all or part of said data determining the selectivity of the broadcast, and all or part of the at least one configuration datum and/or the at least one broadcast transmitter identifier having been stored beforehand in the at least one memory.
