    摘要: Provided are an encoding and decoding method and an apparatus for implementing the same in which a processing order for predetermined-size blocks included in a macroblock is defined in order to efficiently use spatial correlation in an image. After a macroblock is divided into first blocks of a predetermined size and motion compensation is performed on each of the first blocks, a second-block processing order for sequentially processing second blocks included in a current first block is determined in order to process a residue between a motion compensation value of the current first block and the current first block in units of the second blocks having a smaller size than that of the current first block.

The method includes selecting a base picture for the unsynchronized picture, generating a predicted motion vector of the current layer from a motion vector of the base picture, subtracting the predicted motion vector from a motion vector of the unsynchronized picture, and encoding the result of subtraction.
