ABSTRACT:
A method, apparatus, computer system, and computer-readable medium for compressing a two-dimensional array of pixels. A plurality of first column pixel differences is generated by differencing successive pixels in a first column with a first pixel of the first column of the array. A plurality of row pixel differences is generated for each row of the array by differencing successive pixels in said each row with an adjacent previous pixel in said each row and a compressed digital video signal representative of the two-dimensional array of pixels is formed by compressing each first column pixel difference of the plurality of first column pixel differences and by compressing each row pixel difference of the plurality of row pixel differences for each row of the array.
