Abstract

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 comprises a plurality of modulators (121A, 121B, 121C), filters (124A, 124B, 124C, 126), and an upconverter 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.
