Abstract

A single-ended, digital, enhanced resolution television system includes a digital encoder (36) and modulator (46), a limited bandwidth medium, such as a conventional 6 MHz wide television channel or a magnetic recording medium for passing or storing the digital modulation; and a digital decoder (60) including single-ended resolution enhancement processes for enhancing resultant picture quality at a display device (86) to an enhanced resolution level.
