A video decoding method and a video decoding apparatus capable of reducing a memory bandwidth in an intensity compensation process are provided. The video decoding apparatus includes: a bit stream parsing unit which parses an input bit stream, extracts intensity compensation data of a picture to be decoded; a decoding unit which decodes the picture to be decoded; and a memory which stores the decoded picture, wherein the decoding unit comprises a motion compensation unit which reads a motion compensation picture, that is referred by the picture to be decoded for motion compensation, from the memory in block unit of a predetermined size, performs intensity compensation with respect to a motion compensation block of the motion compensation block using the intensity compensation data, and performs the motion compensation with respect to the intensity-compensated motion compensation block. |
