    Abstract: A digital micromirror device (60) for displaying a wide television image comprising a 16:9 array of mirror elements suspended over a substrate, each mirror element having at least one address electrode formed on the substrate between the substrate and the mirror element. An array of memory cells (62) is formed on the substrate, each memory cell in communication with at least one address electrode. An array of input shift registers (64) in communication with the memory cells (62) is formed on the substrate for receiving a series of input image data words and for driving the image data to the memory cells (62). The digital micromirror device (60) enables the efficient reproduction of standard and wide-television images.

    Abstract: An improved processing system (10) for video signal processing. The system uses only one newer version scan-line video processor (12) at nearly maximum efficiency, with a digital input that is at a common rate. The processor performs motion detection, motion adaptive scan conversion, horizontal and vertical scaling and applies sharpness control within a limited amount of instruction space, and applies these functions to four different video formats.

    Abstract: An improved image scaling filter for a video display where a coefficient value (COFF 1, 2, 3, 4) for the closest input lines to a given output line that are less than two line lengths from the given output line are determined by cubic interpolation using the line distances. The input lines are multiplied (23) by the coefficient (COFF) for that line and the multiplied closest input line values are summed (25) to determine the output line value.

    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 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).
