An HD upconverter is a device that solves two problems, both of which are due to the collision of old technology with new technology. The analog signal still present in a lot of our electronics is colliding with the all-digital developments that now control the electronics industry.

An upconverter allows the digital information stored on a DVD to be transmitted directly to a hi-definition TV without ever having to be converted to an analog signal. An upconverter also takes the lower screen resolution on most DVDs and "upconverts" it to the higher resolutions offered by HDTVs.
