Method and apparatus for selectively encoding/decoding a video signal

摘要

An improved method/apparatus processes a video signal by selectively encoding and decoding a plurality of blocks included in the video signal. The encoding method comprises the steps of: selecting a plurality of processing blocks from an motion compensated error signal and deciding position data of the processing blocks, wherein error values contained in the processing blocks are larger than the remaining error values and each of the position data of the processing blocks denotes a left top pixel position of each of the processing blocks; transforming the processing blocks to a plurality of sets of transform coefficients; converting the plurality of sets of transform coefficients into a plurality of sets of quantized transform coefficients; and combining the plurality of sets of quantized transform coefficients and the position data of the processing blocks, thereby providing an encoded signal. <IMAGE>
