Abstract
An apparatus and method to compress a video signal uses a motion compensated DCT (Discrete Cosine Transform) type approach. However, instead of relying upon a DCT coder to process a motion residual signal, the motion residual signal is processed by a pattern marcher. The pattern marcher identifies regions in the motion residual signal that have not been accurately reproduced on account of image motion. Each of these regions is compared to a set of library patterns in a pattern library. The pattern marcher links each region with a selected library pattern, which accurately characterizes the region. The pattern matcher forms an atom parameter signal characterizing each selected library pattern. The atom parameter signal is transmitted as a compressed version of the video signal. After transmission, the video signal is reconstructed from the atom parameter signal. In particular, a pattern fetcher is used to interpret the atom parameter signal to identify the selected library patterns used to characterize the motion residual signal. The selected library patterns are combined with other information to reconstruct the video signal.
