MoCA gateway splitter
First Claim
1. A passive CATV/MoCA signal distribution system comprising:
- an input port for receiving a CATV input signal;
an RF/CATV output terminal;
a modem port;
a Gateway port for connection to a Gateway device receptive of CATV and MoCA signals;
first splitter means having an input connected to said input port for splitting said CATV signal into first, second, third, and fourth CATV signal outputs, said fourth CATV output signal being directly connected to said RF/CATV output terminal;
diplex filter means individually receptive of said first and third CATV signal outputs, and individually bidirectionally receptive of MoCA signals, for both electrically isolating said first and third CATV signal outputs from said MoCA signals to prevent MoCA signals being connected to said input port, and for individually bidirectionally connecting CATV and MoCA signals to both said modem port, and to said Gateway port, respectively;
second splitter means for individually bidirectionally receiving MoCA signals from a plurality of individual MoCA devices associated with a plurality of MoCA clients, respectively, for providing said MoCA signals to said diplex filter means for connection to both said modem port, and said Gateway port, the latter connection providing each of said plurality of MoCA clients the ability to independently program said Gateway device to record their respective desired CATV programs for later viewing, whereby said system prevents said CATV signals and MoCA signals from being combined at said input port;
said diplex filter means includes;
a first diplex filter including a lowpass filter section for receiving said first CATV signal output, and a highpass filter section for bidirectionally receiving MoCA signals from said second splitter means for connecting said CATV and MoCA signals to said modem port, while electrically isolating said MoCA signals both from said first splitter means, and said input port; and
a second diplex filter including a lowpass filter section for receiving said third CATV output signal, and a highpass filter section for bidirectionally receiving MoCA signals from said second splitter means, for connecting said CATV and MoCA signals to said Gateway port, while electrically isolating said MoCA signals both from said first splitter means, and said input port; and
said second splitter means includes;
a resistive splitter including a plurality of resistors each having one end connected in common, with other ends of said plurality of resistors being individually connected to said plurality of MoCA devices, respectively, and individually connected to the highpass filter sections of said first and second diplex filters, respectively.

Abstract
A CATV/MoCA signal distribution system includes a first 2-way hybrid splitter for receiving a CATV input signal and splitting it into first and second CATV output signals, a second 2-way hybrid splitter for receiving the second CATV output signal and splitting it into third and fourth CATV output signals, with the latter being connected to a CATV output port. A first diplex filter is receptive of the first CATV output signal, and MoCA signals for providing electrical isolation therebetween and connecting them to a modem port. A second diplex filter is receptive of the third CATV output signal and MoCA signals for providing electrical isolation therebetween and connecting them to a Gateway port. A resistive splitter is connected between the first and second diplex filters and a plurality of individual MoCA signal ports for providing bidirectional MoCA signal flow therebetween.
