Video decoding methods, video encoding methods, and computer-based reading methods (not temporary)

Abstract

The invention relates to a method and apparatus for decoding video, and a method and apparatus for encoding video. The method for decoding video under this invention may include the step of determining the internal prediction mode of the current block, determining the direct current (DC) value using reference samples adjacent to the current block when the internal prediction mode of the current block is DC, and acquiring the prediction sample of the current block based on the DC value.
