Abstract
The present invention relates to a video decoding method. [Solution] The video decoding method according to this document includes the steps of: configuring an MPM (Most Probable Mode) list that includes candidate intra-prediction modes for the current block; deriving the intra-prediction mode for the current block from the MPM list based on MPM index information that indicates the intra-prediction mode for the current block from among the candidate intra-prediction modes included in the MPM list; generating a prediction sample for the current block based on the intra-prediction mode; and generating a restored picture for the current block based on the prediction sample, wherein the step of configuring the MPM list is characterized in that, based on the case where the value of the reference line index information indicating the reference line used for intra-prediction of the current block is not 0, the DC mode is derived as one of the candidate intra-prediction modes and included in the MPM list.
