Abstract: A video compensation system for analog video transmission is described. The compensation system is employed in an analog video switching circuit such that each time a conductive path is switched, the system automatically tests the new switch path for a new compensation value. The compensation value is determined by measuring the response of the new path to a set of tones that are applied to the conductive path, the response to which is measured against a table of responses previously recorded. The measured responses are compared to the recorded responses to determine an appropriate compensation control voltage, which is applied to an equalizer system. In an alternative embodiment, the skew compensations also provided between red, green, and blue twisted pair lines in the cables by performing comparative analysis between corresponding pairs of the red, green, and blue signals.
