Abstract

See full text

A digital television system (10) System (10) may receive a video signal at composite video interface and separation circuit (16). The video signal is separated into component form by composite video interface and separation circuit (16). The component video signals are converted to digital component video signals in analog to digital converter circuit (18). Line slicer (14) divides each line of digital component 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 component video signals may be formatted for displays (26a) through (26c) in formatters (24a) through (24c). Each formatter (24a) through (24c) may comprise a plurality of first in-first out buffer memories (34a) through (34j). One of each channel signal processors (22a ) through (22d) may be coupled to two of first in-first out buffer memories (34a) through (34j). Additionally, each formatter (24a) through (24c) may comprise channel data format units (38a) through (38d), each associated with a channel of, for example, display (24a). Channel data format units (38a) through (38d) are coupled to appropriate of first in-first out buffer memories (34a) through (34j) via multiplexers (36a) through (36d). Each formatter (24a) through (24c) may remove overlap between channels of system (10) and may format the processed video signal into appropriate channels for displays (26a) through (26c).
