Patent ID: 8131386

Claim:
A method for combining a selector/encoder with one of a single pair of A and B speakers and at least one of said pair of A and B speakers via a sound distributor into a sound distribution system of an home automation by propagating an encoded stereo signal to said A speaker via one of a single segment and a cascading segments of an interconnection cable selected from a group comprising at least one twisted pair, a multi twisted pair cable, a fitted multi twisted pair cable and combinations thereof, wherein at least one segment of said cascading segments is intersected by a wall socket selected from a group comprising a connector, a pigtail, a fitted pigtail, a junction box, a junction board, a junction strip, a terminal block and combinations thereof; each of said A speaker includes a decoding unit for decoding said stereo signal, a stereo amplifier for amplifying the decoded signal and feeding amplified stereo signal to said A and B speakers and a CPU for exchanging serial signals via one of multiplexed into said encoded stereo signal and through a third twisted pair of said interconnection cable with one of said selector/encoder direct and with said selector/encoder via said distributor, said method comprising the steps of: a. interconnecting said selector/encoder with said A speaker by one of directly via said single segment and through said sound distributor via said cascading segments for feeding said encoded stereo signal to said decoder; b. connecting said selector/encoder to a power supply for powering said sound distribution system including said A speaker by a feed selected from a group comprising a constant current via said one twisted pair, a DC power via a second twisted pair of said interconnection cable, said constant current via said one twisted pair cascading through said sound distributor, and said DC power via said second twisted pair cascading through said sound distributor; c. interconnecting a twisted pair of a subsequent segment cable cascading between said A and B speakers for feeding B channel of said amplified stereo signals to said B speaker; d. connecting a stereo cable between an input terminals of said selector/encoder and an output terminals of at least one music signal source; e. exchanging said serial signals between said selector/encoder and said CPU via one of said third twisted pair and said multiplexed via said one twisted pair; f. operating said sound distribution system via touch keys of said selector/encoder or via a remote control unit associated with said selector/encoder.
