Method and apparatus for sequential color imaging
Scott D. Heimbuch,Jeffrey B. Sampsell,Robert J. Gove,Stephen W. Marshall,Donald B. Doherty,Gary L. Sextro,Carl W Davis,Joseph G Egan +7 more
TL;DR: In this article, a sequential color system is provided in which a processor (22) is coupled to a memory (24) and a receiver (27). Images are generated by shining light from a light source (28) through a color wheel (30) and onto DMD array (26).

Digital television system
Robert J. Gove,Stephen W. Marshall,Vishal Markandey,Donald B. Doherty,Richard C. Meyer,Scott D. Heimbuch +5 more
TL;DR: In this article, a line slicer 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).
Patent
Color phase control for projection display using spatial light modulator
TL;DR: In this article, a spatial light modulator (SLM) is used to color the SLM-generated images and a frame memory is managed so that, if the phase of the incoming video signal changes, a desired phase relationship between the color wheel position and the data available to SLM can be maintained.
Patent
System and method for packing data into video processor
Robert J. Gove,Donald B. Doherty,Stephen W. Marshall,Carl W Davis,Joseph G Egan,Richard C. Meyer,Jeffrey B. Sampsell,Scott D. Heimbuch +7 more
TL;DR: In this paper, a system consisting of demultiplexer (32), first and second first in-first out buffer memories (34) and (36), and multiplexer(38) is described.
Patent
Film-to-video format detection for digital television
TL;DR: In this article, a film-to-video format detector (24) for a digital television receiver (10) is presented. The detector receives pixel data from a current field and a second preceding field and determines a set of pixel difference values, sums them to obtain a field difference value, and compares the field difference values to a threshold.
