Abstract
A multi-dimensional data enhancement system can be embedded within a video cable for providing enhanced video images from a video signal source to a display. The multi-dimensional data enhancement system can also be provided in a switching box that allows a user to connect multiple video signal sources to the box and then select a particular video signal source from the group. The selected signal is then enhanced by the switching box before the signal is shown on a display.
