Abstract
Abstract A method and structure for reformatting digitized standard video data for input into a binary spatial light modulator. The data enters circuitry that separates all of the equally weighted binary data into line segments, which are then stored. The data is then read out of the memory in such a manner that the proper digital samples correspond to the proper rows and columns of the spatial light modulator.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
97 words
A method for displaying data from a standardized digital video signal comprising: a. holding digital samples in a buffer, wherein the width of said buffer corresponds to the width of one digital sample; b. reading said digital samples in words, wherein said words correspond to columns of said buffer; c. storing said words in a frame memory; d. transferring the contents of said frame memory to the inputs of a spatial light modulator array; e. controlling said array to display said data; and f. repeating steps a-e until said standardized video data stream is no longer available.
Claim 2
Independent Claim
97 words
A method for displaying data from a standardized digital video signal comprising: a. holding digital samples in a buffer, wherein the width of said buffer corresponds to the width of one digital sample; b. reading said digital samples in words, wherein said words correspond to columns of said buffer; c. storing said words in a frame memory; d. transferring the contents of said frame memory to the inputs of a spatial light modulator array; e. controlling said array to display said data; and f. repeating steps a-e until said standardized video data stream is no longer available.
Claim 3
Dependent Claim
27 words
The method as claimed in claim 1 wherein said reading step further comprises reading the samples such that each word contains bits of the same binary weight.
Claim 4
Dependent Claim
49 words
The method as claimed in claim 1 wherein said storing step further comprises storing the words of the same binary weight for a set of columns of said spatial light modulator array so that the words of the same binary weight are spatially contiguous for each set of columns.
Claim 5
Dependent Claim
25 words

Claim 6
Independent Claim
101 words
A system for displaying a standard digital video signal comprising: a. at least one buffer for holding digital samples, wherein said buffer's width is substantially equal to the length of one of said samples; b. readout circuitry for reading said samples from said buffers by words, wherein said words correspond to columns of said buffer and word length is substantially equal to the number of samples in said buffers; c. a frame memory for storing said words; d. a spatial light modulator array; and e. transfer circuitry for transferring said words from said frame memory to said spatial light modulator array.
Claim 7
Independent Claim
101 words
A system for displaying a standard digital video signal comprising: a. at least one buffer for holding digital samples, wherein said buffer's width is substantially equal to the length of one of said samples; b. readout circuitry for reading said samples from said buffers by words, wherein said words correspond to columns of said buffer and word length is substantially equal to the number of samples in said buffers; c. a frame memory for storing said words; d. a spatial light modulator array; and e. transfer circuitry for transferring said words from said frame memory to said spatial light modulator array.
