Abstract
The present invention provides for eliminating the requirement for cable modems and routers to be installed in subscribers homes, and/or establishments, by instead including the cable modems and routers in a CATV provider's main distribution line, for sharing amongst a plurality of subscriber homes and/or establishments.
Claims21
A community antenna television (CATV) distribution system comprising:
- a CATV provider main distribution system that comprises:
- a fiber node that converts CATV optical signals from a headend of the CATV provider main distribution system into CATV RF signals,
- an RF splitter that splits the CATV RF signals into CATV modem signals and Power/RF signals, wherein the Power/RF signals comprise a low frequency AC powering voltage, and
- one or more taps;
- a CATV modem, located at at least one of the one or more taps, that converts the CATV modem signals into Ethernet signals;
- an Ethernet-to-RF converter, co-located with the CATV modem, that comprises:
- a coaxial input that receives the Power/RF signals,
- an Ethernet input that receives the Ethernet signals,
- a band reject filter that receives the Power/RF signals from the coaxial input, wherein the band reject filter rejects frequencies of Power/RF signals which are in a predetermined frequency band to form first filtered signals,
- an Ethernet-to-RF transceiver that receives the Ethernet signals from the CATV modem and converts the Ethernet signals into RF signals,
- a bandpass filter that receives RF signals from the Ethernet-to-RF transceiver and permits transmission of portions of the RF signals within the predetermined frequency band to form second filtered signals,
- an RF combiner that individually receives the first filtered signals and the second filtered signals from the band reject filter and the bandpass filter and combines the first filtered signals and the second filtered signals to form combined signals, and
- a coaxial output that outputs the combined signals from the RF combiner,
- wherein the one or more taps comprises at least one CATV tap for receiving the combined signals from the coaxial output of the Ethernet-to-RF converter .

An Ethernet-to-RF converter, comprising:
- a coaxial input that receives Power/RF signals from a community antenna television (CATV) provider, wherein the Power/RF signals comprise a low frequency AC voltage that is passed to a power regulator;
- an Ethernet input that receives Ethernet signals;
- a band reject filter that receives the Power/RF signals from the coaxial input, wherein the band reject filter rejects frequencies of the Power/RF signals which are in a predetermined frequency band to form first filtered signals;
- an Ethernet-to-RF transceiver that receives the Ethernet signals from the Ethernet input and converts the Ethernet signals into RF signals;
- a bandpass filter that receives the RF signals from the Ethernet-to-RF transceiver and permits transmission of portions of the RF signals within the predetermined frequency band to form second filtered signals;
- an RF combiner that individually receives the first filtered signals and the second filtered signals from the band reject filter and the bandpass filter and combines the first filtered signals and the second filtered signals to form combined signals;
- and
- a coaxial output that outputs the combined signals from the RF combiner.

A community antenna television (CATV) distribution system comprising:
- a CATV provider main distribution line that comprises :
- a fiber node that converts optical signals from a headend of the CATV provider main distribution line into CATV RF signals,
- an adapter that adds a low frequency AC voltage to the CATV RF signals to form Power/RF signals, and
- one or more taps;
- an Ethernet-to-optical converter that converts the optical signals from the headend into Ethernet signals;
- an Ethernet-to-RF converter communicatively coupled to the Ethernet-to-optical converter that comprises:
- a coaxial input that receives the Power/RF signals, wherein the voltage from Power/RF signals is passed to a power regulator,
- an Ethernet input that receives the Ethernet signals,
- a band reject filter that receives the Power/RF signals from the coaxial input, wherein the band reject filter rejects frequencies of Power/RF signals which are in a predetermined frequency band to form first filtered signals,
- an Ethernet-to-RF transceiver that receives the Ethernet signals from the Ethernet input and converts the Ethernet signals into RF signals,
- a bandpass filter that receives RF signals from the Ethernet-to-RF transceiver and permits transmission portions of the RF signals within the predetermined frequency band to form second filtered signals,
- an RF combiner that individually receives the first filtered signals and the second filtered signals from the band reject filter and the bandpass filter and combines the first filtered signals and the second filtered signals to form combined signals,
- and a coaxial output that outputs the combined signals from the RF combiner;
- and
- wherein the one or more taps comprises at least one CATV tap for receiving the combined signals from the coaxial output of the Ethernet-to-RF converter.
12 more elements
A method for community antenna television (CATV) distribution, the method comprising:
- receiving, by an input of an Ethernet-to-RF converter, Power/RF signals from a CATV provider, wherein the Power/RF signals comprise a low frequency AC voltage that is passed to a power regulator of the Ethernet-to-RF converter;
- receiving, by an Ethernet input of the Ethernet-to-RF converter, Ethernet signals from the CATV provider;
- forming, by a band reject filter of the Ethernet-to-RF converter, first filtered signals by receiving the Power/RF signals from the input and rejecting frequencies of the Power/RF signals which are in a predetermined frequency band to form first filtered signals;
- converting, by an Ethernet-to-RF transceiver of the Ethernet-to RF converter, the Ethernet signals from the Ethernet input into RF signals;
- forming, by a bandpass filter of the Ethernet-to-RF converter, second filtered signals by receiving the RF signals from the Ethernet-to-RF transceiver and permitting transmission of portions of the RF signals within the predetermined frequency band;
- and
- forming, by an RF combiner of the Ethernet-to-RF converter, combined signals by individually receiving the first filtered signals and the second filtered signals from the band reject filter and the bandpass filter and combining the first filtered signals and the second filtered signals;
- and
- outputting, by an output of the Ethernet-to-RF converter, the combined signals from the RF combiner.
