POLARITY CORRECTION CIRCUIT AND SYSTEM INCORPORATING THE SAME

摘要

A polarity correction circuit including a polarity controller and an inversion circuit. The polarity controller is configured to detect an incorrect polarity in a polarity sensitive signal and provide inversion signal in response to the incorrect polarity. The inversion circuit inverts the polarity sensitive signal in response to the inversion signal. A video system consistent including a polarity correction circuit consistent with the invention, and a circuit for correcting mis-wiring of transmit and receive connections are also provided.
