ABSTRACT:
Embodiments of the present invention include systems, methods and apparatus for amplifying a composite video signal transmitted over long distance unshielded twisted pair cabling. The apparatus and system may include a plurality of amplifiers, an analog switch, and a control unit. The control unit generates a configuration signal to enable the output of one or more amplifiers (which may be serially connected) and configure the analog switch. A user input may be provided for manually configuring the amplifiers and analog switch. When the video signal is a color signal, the control unit may automatically configure the amplifiers and analog switch with reference to the amplitude of the color burst.
