    Abstract: A method for intra prediction comprises determining a first MPM candidate corresponding to a left-side candidate block on the basis of a position of the left-side candidate block adjacent to a left side of a current block; determining a second MPM candidate corresponding to an upper-end candidate block on the basis of a position of the upper-end candidate block adjacent to an upper end of the current block; generating an MPM candidate list including a plurality of MPM candidates, on the basis of the first MPM candidate and the second MPM candidate; and determining one MPM candidate of the plurality of the MPM candidates that constitute the MPM candidate list as an intra prediction mode of the current block, and performing intra prediction for the current block on the basis of the determined intra prediction mode to generate a prediction block corresponding to the current block.

    Abstract translation: 用于帧内预测的方法包括:基于与当前块的左侧相邻的左侧候选块的位置来确定与左侧候选块相对应的第一MPM候选; 基于与当前块的上端相邻的上位候选块的位置,确定与上位候选块对应的第二MPM候选; 基于所述第一MPM候选和所述第二MPM候选,生成包括多个MPM候选的MPM候选列表; 以及将构成MPM候选列表的多个MPM候选的一个MPM候选确定为当前块的帧内预测模式,并且基于所确定的帧内预测模式对当前块执行帧内预测,​​以生成预测块 对应于当前块。

    Abstract: A video decoding method performed by a video decoding device according to the present document comprises the steps of: acquiring image information from a bitstream, the image information including a picture header associated with the current picture including a plurality of slices; parsing, from the picture header, a first flag indicating whether information necessary for an inter-prediction operation for a decoding process is present in the picture header; parsing, from the picture header, a second flag indicating whether information necessary for an intra-prediction operation for the decoding process is present in the picture header; and generating prediction samples by performing at least one of intra-prediction or inter-prediction for the slices in the current picture on the basis of the first flag or the second flag.
