ABSTRACT:
Devices for reducing and determining the skew between colour video signals transmitted over at least two different video cables are described. A KVM extender including such devices is also described. The skew reduction device includes a plurality of video signal transmission tracks selectably connectable to each of the video cables to increase the video signal transmission path length so as to more closely matching the total video signal path length for each of the colour video signals. The skew determination device comprises a processing device, a signal generator for applying measuring signals to each of the video signal cables and signal detection circuitry to receive measuring signals transmitted over the video signal cables. Detection signals are output to the processing device which is programmed to determine an indication of the transmission path length difference between the video signal cables.
