摘要： The present invention relates to a method for encoding/decoding a video. To this end, the method for decoding a video may include: deriving a spatial merge candidate from at least one of spatial candidate blocks of a current block, deriving a temporal merge candidate from a co-located block of the current block, and generating a prediction block of the current block based on at least one of the derived spatial merge candidate and the derived temporal merge candidate, wherein a reference picture for the temporal merge candidate is selected based on a reference picture list of a current picture including the current block and a reference picture list of a co-located picture including the co-located block.

摘要： Provided are method and apparatus methods and apparatuses for encoding an intra-prediction mode based on a secondary IPM. The present invention may comprises a first decision step of determining whether an intra-prediction mode of a current block is included in a first candidate mode set including M candidate modes (M is an integer equal to or greater than 1); a second decision step of determining whether the intra-prediction mode of the current block is included in a second candidate mode set including N candidate modes (N is an integer equal to or greater than 1) based on a first determination result representing a determination result of the first decision step; and an intra prediction mode encoding step of encoding the intra-prediction mode of the current block based on the first determination result or a second determination result representing a determination result of the second decision step.
