Abstract
A video display system which can receive and display a number of different video signals having different formats utilizing a processor extract the image from a stream of digital signals to produce a digitized image to be displayed by a digital spatial light modulator.
Claims21
A standard independent video display system comprising:
- (a) a receiver receiving image information including chrominance and luminance encoded therein at a first data rate;
- (b) a converter in electrical communication with said receiver for converting said image information into digital codes representative of said chrominance and luminance of a plurality of pixels;
- (c) a memory coupled to said converter for selectively receiving and storing said digital codes;
- (d) a processor coupled to said memory for selectively performing operations on at least some of said digital codes;
- and
- (e) a spatial light modulator coupled to said memory for receiving selected ones of said digital codes at a second data rate to modulate a light source into a plurality of light beams perceptually varying in chrominance and luminance with said second data rate higher than said first data rate.

Method for a standard independent video display system comprising the steps of:
- (a) receiving image information including chrominance and luminance encoded therein at a first data rate;
- (b) converting said image information into digital codes representative of said chrominance and luminance of a plurality of pixels;
- (c) storing said digital codes;
- (d) performing operations on at least some of said digital codes;
- and
- (e) modulating a light source into a plurality of light beams perceptually varying in chrominance and luminance, at a second data rate higher than said first data rate.

A standard independent video display system comprising:
- (a) a receiver for receiving a serial stream of pixel data including chrominance and luminance encoded therein at a first data rate;
- (b) a converter coupled to said receiver for converting said serial stream into digital codes representative of said chrominance and luminance of each pixel;
- (c) a first memory coupled to said converter for selectively receiving and storing said digital codes;
- (d) a processor coupled to said first memory for selectively reading and performing data manipulation operations on predetermined ones of said digital codes;
- (e) a second memory coupled to said processor for selectively receiving and storing results of said data manipulation operations from said processor;
- and
- (f) a spatial light modulator coupled to said second memory for receiving selected ones of said stored results at a second data rate, said modulator operative in response to said selected ones of said stored results, to modulate a light source into a plurality of light beams wherein said light beams perceptually varying in chrominance and luminance with said second data rate higher than said first data rate.
