Abstract
A hardened DVI transmitter includes a differential driver to convert a ground-up DVI signal into a balanced DVI signal. The balanced DVI signal is transmitted to a DVI compliant cable, through one or more transformers. Transformers effectively remove direct current interference from sources such as lightning. A hardened DVI receiver receives the balanced DVI signal, from the DVI compliant cable, through one or more complimentary transformers. The balanced DVI signal is then converted back to a ground-up DVI signal. By this method, DVI compliant signals may be sent through DVI cables longer than ten meters, and survive interference from lightning.
