Original Abstract Submitted
A method and a device for encoding/decoding a video are provided. A method for decoding a video according to the present disclosure includes deriving a most probable mode (MPM) list based on intra prediction modes of neighboring blocks adjacent to a current block. The method for decoding the video also includes generating prediction pixels by applying candidate modes in the MPM list or the intra prediction modes of the neighboring blocks to reference pixels of a first region adjacent to the current block. The method for decoding the video also includes calculating a sum of absolute transformed difference (SATD) between the prediction pixels and reconstructed pixels of the first region. The method for decoding the video also includes deriving a first intra prediction mode, based on the SATD. The method for decoding the video also includes deriving an intra prediction mode of the current block, based on the first intra prediction mode. The method for decoding the video also includes generating a prediction block of the current block, based on the intra prediction mode of the current block.
