Abstract

The single removable cable is capable of transporting both the power and the data between a powering device and one or more powered devices. At least one signal line is configured to transport data over the single removable cable. At least one electrical conductor configured to transport power for operating the one or more powered devices.

First claim

What is claimed is:

1. A system configured to transport data and power over at least one common electrical conductor, the system comprising:
a powering device comprising:
at least one audio/video component;
a power management unit;
a data management unit;
one or more powered devices providing one or more audio/video functions and configured to receive and operate on control data and audio/video data from the powering device and transmitting data to the powering device and to receive power directly and exclusively from the powering device over a cable; and
a single removable cable capable of transporting both the power and the data between a powering device and the one or more powered devices wherein the single removable cable comprises multiple coaxial conductive pairs, each coaxial conductive pair comprising an axial first conductor and a second conductor around the first conductor.

2. The cable of claim 1 , wherein the single removable cable comprises an axial first conductor, a second conductor around the first conductor, and a third conductor around the second conductor.
