1. A display system comprising:

  • a. a source of digitized video data, wherein said source decodes an incoming signal to locate image information and recognize any format of said data;

    b. a video memory for receiving said image information in said format from said source;

    c. a signal processor for receiving said image information from said video memory and processing said information for display, wherein said processor is operable to perform interlace to progressive scan conversion;

    d. a buffer memory for receiving said processed information from said processor;

    e. at least one digital micromirror device for receiving said processed information from said buffer memory, each said device including an array of individually addressable cells and addressing circuitry, wherein said addressing circuitry receives said processed information for said individually addressable cells such that each of said individually addressable cells responds to said processed information;

    f. at least one light source for illuminating said individual cells during the interval when said individual cells are responding to said addressing information; and

    g. optics such that light reflected from those said individual cells receiving information operative to change the angle of deflection of said cell is captured and focused on a display surface.
