Definitions for "Balanced Signal"
A video signal is converted to a balanced signal to enable it to be transmitted along a `twisted pair' cable. Used in situations where the cabling distance is too great.
a video signal that has been converted for transmission along a medium other than coaxial cable
This refers to a type of video signal which is transmitted through a twisted pair cable. It is called balanced because the signal travels through both wires, this way both wires are equally exposed to external interference, so by the time the signal reaches its destination, the end noise will be cancelled at the input of a differential buffer stage.
