Video encoding/decoding method and apparatus

A video encoding method comprising:

• determining a most probable mode (MPM) list, based on intra prediction modes of neighboring blocks adjacent to a current block;
• 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;
• calculating a sum of absolute transformed difference (SATD) between the prediction pixels and reconstructed pixels of the first region;
• determining a first intra prediction mode, based on the SATD;
• determining an intra prediction mode of the current block, based on the first intra prediction mode;
• and
• generating a prediction block of the current block, based on the intra prediction mode of the current block.

• 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;
• calculating a sum of absolute transformed difference (SATD) between the prediction pixels and reconstructed pixels of the first region;
• deriving a first intra prediction mode, based on the SATD;
• deriving an intra prediction mode of the current block, based on the first intra prediction mode;
• and
• generating a prediction block of the current block, based on the intra prediction mode of the current block.
