Abstract
This invention disclosure relates to a community access television (CATV) signal distribution system which improves signal isolation issues for systems which are distributing both CATV signals and in-home entertainment (IHE) signals. The signal distribution system includes a signal input port, a first multi-port signal splitter and a second multi-port signal splitter. The first multi-port signal splitter is coupled to the signal input port through a first diplexer, and the second multi-port signal splitter is coupled to the signal input port through a second diplexer. In some embodiments the first diplexer high-pass node and the second diplexer high-pass node are coupled together. In some embodiment the signal distribution system includes a signal output port coupled to the signal input port through a third diplexer. The high-pass node of the third diplexer is coupled to the high-pass node of the first diplexer.
