Abstract
A device that incorporates teachings of the present disclosure may include, for example, a controller to provide low loss connectivity to a plurality of coaxial ports over a broadband range of frequencies in a coaxial network providing Ethernet networking, detune secondary coaxial splitters in the coaxial network that reduces an output-to-output isolation loss among secondary coaxial splitter output ports, and enable re-distribution of modulated radio frequency video signals from a point on the coaxial network to any alternative point on the coaxial network. Other embodiments are disclosed.
Claims25
A method, comprising:
- setting a port impedance mismatch in a splitter for Ethernet networking over coaxial cables in a home coaxial network;
- detuning any secondary splitter coupled to the home coaxial network;
- and
- enabling distribution of modulated radio frequency video over the home coaxial network to deliver analog video to a plurality of repeater devices coupled to the home coaxial network.
A computer-readable storage medium, comprising computer instructions for:
- creating a port impedance mismatch in a splitter operating in a home coaxial network resulting in the detuning of a secondary splitter coupled to the home coaxial network;
- detuning a secondary splitter coupled to the home coaxial network;
- and
- enabling distribution of modulated video over the home coaxial network to deliver analog video to a plurality of repeater devices coupled to the home coaxial network.
A device, comprising a controller to:
- provide low loss connectivity to a plurality of coaxial ports over a broadband range of frequencies in a coaxial network providing Ethernet networking;
- detune secondary coaxial splitters in the coaxial network that reduces an output-to-output isolation loss among secondary coaxial splitter output ports;
- and
- enable re-distribution of modulated radio frequency video signals from a point on the coaxial network to an alternative point on the coaxial network.
A device, comprising:
- a splitter providing low loss connectivity to a plurality of coaxial ports over a range of frequencies in a coaxial network by having a port impedance mismatch that causes a lower power transfer to each leg of the splitter and a higher return loss relative to an impedance matched splitter;
- wherein the splitter is constructed to detune a secondary coaxial splitter when coupled in an Ethernet over coaxial network and constructed to reduce an output-to-output isolation loss among secondary coaxial splitter output ports when coupled in the Ethernet over coaxial network.
