Method and apparatus for decoding video

The present invention relates to a method and an apparatus for decoding video. A method and an apparatus for encoding/decoding a video comprises the following steps: generating an encoded image data by encoding a current block partitioned into a plurality of subblocks; generating an encoded partition information data by encoding partition information of the current block; generating a bitstream including the encoded image data and the encoded partition information data; and then reconstructing the video image from the generated bitstream. According to the present disclosure, when encoding a high resolution video with variable sized blocks, various block shapes may be used for the encoding, and efficient encoding and decoding of the block partition information can improve the compression efficiency.
