Abstract
An apparatus and method for partitioning video images into a first and second portion for more efficient compression/decompression and transfer across a network is disclosed. The present invention includes a video controller that stores a reference image with a plurality of reference pixels, receives a foreground image, compares the reference image with the foreground image thereby identifying matched pixels, and replaces the matched pixels in the foreground image with null pixels. The video controller also compresses the foreground image, and transfers the foreground image including null pixel values over a network.
