1. A receiver for processing a video signal from a power line, comprising:
- three input lines connected to a standard power adaptor, at least one input line carrying the video signal;
two output lines;
a processing means comprising conductive elements including switching means and arrangements of conductive paths in which1) a first of said three input lines is connected to said switching means by multiple branch lines,2) the second and third of said three input lines are connected to said switching means by multiple branch lines,3) a first of said two output lines is connected to said switching means by multiple branch lines,4) the second of said two output lines is connected to said switching means,the switching means facilitates the selection of alternates of said conductive paths and said conductive elements to pass the video signal from the at least one input line carrying the video signal to at least one of said output lines thereby tuning the impedance of the receiver, andthe processing means enables the simultaneous electrical connection via said conductive elements of one of the output lines with two of the input lines.

Abstract
A VCR transmission device is disclosed including a transmitting unit capable of receiving a VCR video signal, conditioning the video signal and outputting the video signal onto a home power line ordinarily carrying an AC power signal. The transmitting device attaches directly to an existing power outlet in the home power line to deliver the video signal from the VCR throughout the home. A receiving unit is then connected to any other power outlet in the home power line to extract the video signal from the power line and to deliver the signal to a television set which may be remote from the VCR.
