Abstract: A method of decoding a motion vector includes: determining at least one prediction motion vector (PMV) candidate block used to determine a PMV of a current block; determining an availability of a motion vector of the at least one PMV candidate block; when there is a PMV candidate block determined to be unavailable, determining the PMV of the current block by using a default motion vector (MV); and obtaining a motion vector of the current block based on the determined PMV.

Abstract: A video decoding method includes determining an intra prediction mode of a current lower block corresponding to one of a plurality of lower blocks generated by splitting an upper block, determining reference samples of the current lower block based on samples adjacent to the upper block, determining a predicted value of a current sample included in the current lower block, by using the reference samples based on the intra prediction mode, and reconstructing the current lower block based on the predicted value, wherein the current sample included in the current lower block is excluded from reference samples of another lower block included in the upper block.
