    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.
