A system for redistributing a broadband audio-visual-data signal to a multiplicity of receiver units within a multiple dwelling unit (MDU) includes a main receiving antenna that receives a broadband video/audio/data signal having a number of individual program multiplex signals therein and a transmodulator device that transmodulates a selected subset of the individual program multiplex signals associated with the broadband signal from a first modulation scheme to a second modulation scheme. The transmodulated signals are broadcast over a cable network, along with terrestrial signals, to individual receiver units at the MDU. The receiver units send requests for user-selected ones of the individual program multiplex signals to the transmodulator device, demodulate the transmodulated and/or terrestrial signals and provide user-specified channels to television sets for display. |
