Abstract

A system for distributing first and second television signals of diverse modulation formats to a number of locations in a multiple-dwelling unit includes first and second antennas for receiving, at the multiple-dwelling unit, respective first and second received television signals having respective first and second, different modulation formats. The system also includes first and second transmodulators for transmodulating the first and second received television signals, respectively, to develop first and second transmodulated signals, respectively. A combiner or diplexer combines the first and second transmodulated signals into a combined signal, and a distributing network distributes the combined signal to each of a plurality of locations. A diplexer at a particular location selected from the number of locations separates the combined signal to recover the first and second transmodulated signals. A demodulator demodulates the second transmodulated signal recovered by the diplexer to develop a demodulated signal having the second modulation format. At the particular location in the multiple-dwelling unit, either the first transmodulated signal recovered by a separator or the demodulated signal developed by the demodulator is coupled to a television set.
