    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.

    摘要: A motion compensation method and apparatus that sequentially use global motion compensation and local motion compensation, a video decoding method, a video encoder, and a video decoder are provided. The motion compensation method includes extracting global motion information of a reference block, performing global motion compensation by applying the extracted global motion information to the reference block, extracting local motion information of the global motion-compensated reference block, and performing local motion compensation by applying the local motion information to the global motion-compensated reference block.

    摘要: A method and apparatus for video encoding/decoding are provided to improve compression efficiency by generating a prediction block using an intra-inter hybrid predictor. A video encoding method includes dividing an input video into a plurality of blocks, forming a first predictor for an edge region of a current block to be encoded among the divided blocks through intraprediction, forming a second predictor for the remaining region of the current block through interprediction, and forming a prediction block of the current block by combining the first predictor and the second predictor.

    摘要: A method and apparatus for video encoding/decoding provides a macroblock used as a unit of video division and encoding formed in various sizes, positions, and shapes to improve compression efficiency according to video characteristics. The video encoding method, divides a video into macroblocks while moving macroblocks in each row and/or each column by a predetermined-size pixel and each of the macroblocks is encoded. A video may also be divided into macroblocks at a position spaced apart from a corner of the video by a predetermined offset and each of the macroblocks is encoded. Encoding may also be performed on each sub-block and sub-blocks having the same prediction mode may be grouped into a macroblock having another form.
