The SKU-RGB is a Video over UTP: Skew Corrector which allows
you to make a skew correction to the individual RGB colors of
a VGA or component video (YPbPr) signal. You can transmit the
signal over Cat5/5e/6 cable.
The SKU-RGB is capable of correcting images with colors that
have become skewed or shifted due to long Cat5/5e/6 cable
runs. The problem happens in the Cat5/5e/6 cable because of
twisting of the pairs of wires at different rates.
