    摘要: A spatial light modulator with hexagonal elements or pixels. The elements include a reflective hexagonal surface supported by flexible hinges. The hinges are in turn supported by support posts away from a substrate. On the substrate are control or address electrodes which control the direction of deflection of the reflective surface by selective build up of electrostatic forces. The use of hexagonal pixels allow the posts and electrodes to be arrayed in horizontal lines, thereby allowing reset of horizontal lines of the pixels.

    摘要: A method and system for accentuating intense white display areas in sequential DMD video systems includes generating a special signal for each pixel that indicates whether to boost the intensity of that pixel in all colors. The method further includes enabling the mirrors to be turned on during times of color boundary of the color wheel such that DMD with mirrors receives different mixes of color light that are integrated together to produce intense white. The system may include degamma lookup tables for each color. The degamma lookup tables are augmented when the special signal is generated.

    摘要: An SLM-based digital display system (10) having a graphics display subsystem (13 and 18) for closed captioning, on-screen displays, and other graphics images that are overlaid on the video image. The graphics display subsystem (13 and 18) has a graphics processor (21) that prepares the graphics data, which is inserted into the video data path after video data processing and prior to a look-up table unit (27). A select logic unit (24) provides a control signal to a multiplexer (26) that selects between video data and graphics data for input to the look-up table unit (27). The look-up table unit (27) performs its mapping according to the type of data received, such as by linearizing video data or palletizing graphics data.

    摘要: A method of encoding video display data, after that data has been previously converted from a film frame rate to a faster video frame rate, such as by 3:2 pulldown. The data is first re-converted to the film frame format, as progressive frames (21). This progressive frame data is processed to determine where scene cuts occur (22). The data is then encoded consistent with MPEG encoding techniques, but with the scene cut information being used to begin groups of pictures (GOPs) at scene cuts and to determine where intrapictures, predicted pictures, or interpolated pictures shall occur (23).

    摘要: 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).

    摘要: An SLM-based video receiver (10) receives a video input on a field-by-field basis at a signal interface unit (11) and passes the input to a processor (12). The processor (12) performs analog-to-digital conversion if the pixel data is analog and also performs other enhancements to prepare the pixel data for loading into a video memory (14). Pixel data from the processor (12), representing a field of pixel data, is stored into the memory (14) for loading into rows of pixel elements of a spatial light modulator (16). The spatial light modulator (16) receives the pixel data in rows. The addressing functions of the spatial light modulator (16) are used to generate additional display rows of pixel data per field. Thus, the SLM-based video receiver (10) displays a video frame having more lines than the field of pixel data.

    摘要: A film-to-video format detector (24) for a digital television receiver (10). The detector (24) receives pixel data from a current field and a second preceding field. It determines a set of pixel difference values, sums them to obtain a field difference value, and compares the field difference value to a threshold. These steps are repeated to obtain a series of field difference indicators. This series is analyzed to determine whether it has a pattern corresponding to a film-to-video format.
