Abstract: A method and apparatus for encoding a skip macroblock by dividing the skip macroblock into smaller skip sub blocks and using predictive motion vectors predicted from motion vectors of blocks adjacent to the skip sub blocks, and a method and apparatus for decoding the skip macroblock is provided. Accordingly, by adding predetermined binary information indicating whether the skip macroblock is divided to the skip macroblock that generally transmits only prediction mode information, division of the skip macroblock can be adaptively applied, or all skip macroblocks can be divided into sub-blocks to be processed, so that pixel values in the skip macroblock can be predicted by using motion vectors of spatially adjacent blocks. Therefore, prediction efficiency increases.
