ABSTRACT:
A method and apparatus processes a video signal by selectively encoding and decoding a plurality of blocks included in the video signal. The encoding apparatus selects a plurality of processing blocks from a motion compensated error signal and decides 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. Then the apparatus transforms the processing blocks to a plurality of sets of transform coefficients and converts the plurality of sets of transform coefficients into a plurality of sets of quantized transform coefficients. The plurality of sets of quantized transform coefficients are combined with the position data of the processing blocks in order to provide an encoded signal.
