Method and apparatus for reducing isolation in a home network

A community access television (CATV) signal distribution system comprising:

• a CATV signal input port configured to connect to a CATV network;
• one or more direct signal output ports;
• a first plurality of broadband signal output ports configured to connect to a first plurality of in-home entertainment devices;
• a second plurality of broadband signal output ports configured to connect to a second plurality of in-home entertainment devices;
• a first multi-port signal splitter comprising a first common terminal and a first plurality of leg terminals;
• a second multi-port signal splitter comprising a second common terminal and a second plurality of leg terminals;
• a third multi-port signal splitter comprising a third common terminal and a third plurality of leg terminals;
• a first diplexer splitter comprising a first common node, a first low-pass node, and a first high-pass node;
• a second diplexer comprising a second common node, a second low-pass node, and a second high-pass node;
• and
• a third diplexer comprising a third common node;
• a third low-pass node, and a third high-pass node, wherein:
• the CATV signal input port is configured to connect to a. CATV network;
• the one or more direct signal output ports connect to the first common node of the first diplexer and are configured to connect to one or more embedded multimedia terminal adapter (eMTA) devices;
• the first plurality of broadband signal output ports connect to the second plurality of legs of the second multi-port splitter;
• the second plurality of broadband signal output ports connect to the third plurality of legs of the third multi-port splitter;
• the first common node of the first multiport signal splitter connects to the signal input port and is configured to receive the CATV signal from the CATV network as an input;
• a first leg of the first multiport splitter connects to the first low-pass node of the first diplexer;
• a second leg of the first multiport splitter connects to the second low-pass node of the second diplexer;
• a third leg of the first multiport splitter connects to the third low-pass node of the third diplexer;
• the first high-pass node of the first diplexer connects to the second high-pass node of the second diplexer, and connects to the third high-pass node of the third diplexer;
• the first high-pass node of the first diplexer, the second high-pass node of the second diplexer, and the third high-pass node of the third diplexer are configured to communicate in-home entertainment band signals in a predetermined high-frequency band between the one or more direct signal output ports, the first plurality of broadband signal output ports, and the second plurality broadband signal output ports;
• and
• the first low-pass node of the first diplexer, the second low-pass node of the second diplexer, and the third low-pass node of the third diplexer are configured to prevent transmission of in-home entertainment band signals to the CATV signal input port from the one or more direct signal output ports, the first plurality of broadband signal output ports, and the second plurality broadband signal output ports.
