Abstract
In a video system in which a video signal source transmits a video signal to a receiver over a transmission line, a method of maintaining a desired voltage level from the video signal source includes the steps of monitoring the level of voltage at the output of the video signal source, and adjusting an input to the video signal source as necessary in order to maintain a desired level of voltage. Thus, when the impedance of the transmission line and receiver change, the output voltage from the video signal source is maintained at a desired level without clipping of the signal when the video signal source is overdriven.
