Appl. No.:

15/806411

International Classification:

H04N 21/426
H04N 21/61

Abstract:

An active MoCA (Multimedia over Coax Alliance) gateway splitter device, including a CATV input port for receiving a CATV input signal, an amplifier for amplifying the CATV signal, at least one MoCA port (connectable to a MoCA device), a plurality of modem/gateway ports (each connectable to a modem or gateway device); and a diplex filter that includes a low-pass filter section and a high-pass filter section. The CATV input port is electrically connected to the modem/gateway ports via the low-pass filter section and the MoCA port is electrically connected to the modem/gateway ports via the high-pass filter section. Accordingly, the MoCA device can communicate bidirectionally with the modem/gateway devices over a higher frequency band, the modem/gateway devices can communicate bidirectionally with the CATV input port over a lower frequency band, and the MoCA device is electrically isolated from the CATV input port.

H04N 21/643

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.
