1. An intelligent device for transmitting information on a modulated RF signal, comprising:

  • an input configured to receive a digital stream containing digital information, the digital information containing at least one destination address to which the digital information is to be sent;

    an RF channel detector configured to detect which dynamically allocated RF channels are currently being used in a wideband signal distribution system, and to generate RF channel in use information identifying which of the dynamically allocated RF channels are currently being used in the wideband signal distribution system;

    a traffic sensor configured to measure an information throughput of the digital information received by the input, and to generate traffic information identifying the information throughput of the received digital information;

    a modulator unit configured to modulate the digital information into at least two separate dynamically allocated RF channels when the traffic information indicates that the information throughput of the digital information exceeds an information capacity of a single RF channel, and to output a modulated RF signal containing the at least two separate dynamically allocated RF channels to the wideband signal distribution system such that the digital information contained in the received digital stream is distributed across the at least two dynamically allocated RF channels output to the wideband signal distribution system; and

    a processor configured toreceive the RF channel in use information generated by the RF channel detector and the traffic information generated by the traffic sensor,determine which dynamically allocated RF channels are available to carry the digital information, from among a plurality of RF channels contained in the modulated RF signal, based on the RF channels which are identified in the RF channel in use information as not currently being used in the wideband signal distribution system,determine a number of dynamically allocated RF channels from among the plurality of RF channels contained in the modulated RF signal on which to carry the digital information received by the input based on the information throughput of the digital information and the information capacity of a single RF channel,instruct the modulator unit to distribute the received digital information across at least two dynamically allocated RF channels by modulating the received digital information into the at least two dynamically allocated RF channels when the traffic information indicates that the information throughput of the digital information exceeds an information capacity of a single RF channel, andinstruct the modulator unit on which specific dynamically allocated RF channels from among the plurality of RF channels to carry the digital information in the modulated RF signal based on the determined number of dynamically allocated RF channels on which to carry the digital information, the at least one destination address contained in the digital information, and the determined available dynamically allocated RF channels which are not currently being used in the wideband signal distribution system.
