<p>A broadcast system supplies multiplexed channels to a plurality of receiving systems. At least one of the receiving systems serves a plurality of living units (75). The common equipment includes a digital receiver (103) processing each multiplexer channel to capture a digital transport stream therefrom and a demultiplexer (105) for separating out the digital signals. A switch (109) routes selected information signals to individual drops or loops going to the living units (75). In one implementation, each digital signal is modulated, and selected modulated signals are routed and transported over telephone wiring to terminals (100) in the living units (75). The terminals (100) demodulate and decode selected program signals for presentation on a television. In a second implementation, a decoder in the common equipment decodes each digital signal, and the common equipment transmits an analog TV channel carrying decoded signals for selected programs over coaxial cables to the living units (75).</p> |
