Abstract
Provided are a video encoding or decoding method and apparatus, which, during video encoding and decoding processes, determine whether an intra prediction mode of the current block is a DC mode, when the intra prediction mode of the current block is the DC mode, in a case where lengths of a height and a width of the current block are the same, determine an average of upper reference samples of the current block and left reference samples of the current block, as a DC value, and in a case where the lengths of the height and the width of the current block are different from each other, determine a weighted average value, which is determined by determining an average of the upper reference samples of the current block as an upper DC value, determine an average of the left reference samples of the current block as a left DC value, and combining the upper value and the left DC value with a predetermined weight, as a DC value, and perform intra prediction on the current block, based on the DC value.
