Abstract
A computer system encodes video display information using parallel processing capabilities of a general-purpose CPU. A driver on the computer system captures the display information into memory and identifies regions of the display that have changed. The identified changed regions are represented in a tree structure which allows the system to identify regions of the display that can be efficiently processed. The identified regions are converted from an RGB color space to a YUV420 color space using a cross-platform parallel processing framework such as OpenCL. By using a cross-platform parallel processing framework, the system is able to utilize parallel processing capabilities of the general-purpose CPU such as SSE or AVX to accelerate the conversion operation.
