Abstract
A method for transmitting a computer display image. In one embodiment, the method comprises determining a pixel boundary, referenced to a sub-tile boundary within a grid of tiles, for a changed portion of the image; identifying i) a uniform tile within the changed portion referenced to a first tile and ii) at least one hybrid sub-tile, associated with the sub-tile boundary, within the changed portion referenced to a second tile adjacent the first tile; engaging an SIMD vector processor to transform the uniform tile to an exit matrix, transform the at least one hybrid sub-tile to at least one DC coefficient, and transform the exit matrix to a first DC coefficient and the at least one DC coefficient to a second DC coefficient; quantizing, encoding and transmitting coefficients of the first and second tiles; and transmitting a binary mask specification for the changed portion adjusted to the sub-tile boundary.
