METHOD AND APPARATUS FOR AUTOMATIC COMPENSATION OF SKEW IN VIDEO TRANSMITTED OVER MULTIPLE CONDUCTORS

摘要

A method and apparatus for automatic detection and compensation of skew between color components of a video source transmitted over a plurality of twisted pair conductors are presented. The system includes a receiver configured to receive separate components of a video source over each twisted pair conductor in a twisted pair cable. Each color component includes a reference signal. High speed comparators and samplers are used to detect the reference signal and measure the skew between the color components. Delay is applied to the first arriving color components to synchronize them in time with the last arriving color component. Skew measurement is continuous and adjustment is automatic while the receiver is receiving a video signal.
