Abstract
A system for distributing one of a plurality of input signals from one location in a building having standard AC power to another location in the building. An input signal is selected by a switcher and, if it is an analog signal, it is converted to a digital signal. The digital signal is then processed to enable it to be superimposed on, and transmitted over, an AC power line to the other location. At the other location the transmitted digital signal is processed again to restore it to its original digital format at which time it can be passed directly to a digital amplifier or converted to an analog signal for further processing.
