An apparatus and method for utilizing the roll-off spectrum of TV transceiver equipment by channelizing wide band data-carrying signals into multiple subchannels. The system enables insertion of data channels into a transmission scheme without occupying video channels. In particular, the apparatus and method functions to transmit 2MHz subchannels of data at roll-off band frequencies to at least one client in a two-way, asymmetric network communication system. |
