Abstract
Abstract It is possible to replace a standard tuning unit in a television with spatial light modulator circuitry to improve the resolution seen by the viewer. The invention herein provides a system architecture, individual parts of the system, and techniques for minimizing the burst data rate while maintaining a reasonable system speed. The resultant system provides better resolution with a manageable data rate and bandwidth.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
52 words
A method of displaying data comprising addressing the contents of memory cells and loading said contents onto display pixels wherein data from an alternate data path is loaded onto said pixels instead of the contents of said memory calls, said data causing all pixels in said row to display the same state.
Claim 2
Independent Claim
52 words
A method of displaying data comprising addressing the contents of memory cells and loading said contents onto display pixels wherein data from an alternate data path is loaded onto said pixels instead of the contents of said memory calls, said data causing all pixels in said row to display the same state.
Claim 3
Independent Claim
65 words
A method of displaying data comprising addressing the contents of memory cells and loading said contents onto display pixels wherein said loading step includes the use of a decoder to address rows of said pixels simultaneously said decoder having additional inputs wherein activation of said inputs causes said decoder to address groups of said rows simultaneously wherein one or more groups may be addressed simultaneously.
Claim 4
Independent Claim
65 words
A method of displaying data comprising addressing the contents of memory cells and loading said contents onto display pixels wherein said loading step includes the use of a decoder to address rows of said pixels simultaneously said decoder having additional inputs wherein activation of said inputs causes said decoder to address groups of said rows simultaneously wherein one or more groups may be addressed simultaneously.
