ABSTRACT:
A digital television system (10) is provided. System (10) may receive a video signal at composite video interface and separation circuit (16). The video signal is separated into separate video signals by composite video interface and separation circuit (16). The separate video signals are converted to digital video signals in analog to digital converter circuit (18). Line slicer (14) divides each line of digital video signal into a plurality of channels such that each channel may be processed in parallel by channel signal processors (22a) through (22d). Each channel signal processor (22a) through (22d) may provide two lines of output for each line of video input. The processed digital video signals may be formatted for displays (26a) through (26c) in formatters (24a) through (24c).
