Abstract
Provided is a video decoding method including obtaining a residue of a first bit-depth with respect to a current block by decoding a bitstream; when intra predicting the current block, generating a prediction block of the current block by using a block that is previously decoded at the first bit-depth and then stored in a buffer; and generating a reconstruction block of the first bit-depth by using the prediction block and the residue of the first bit-depth. When the current block is inter predicted, the video decoding method may further include generating a prediction block of a second bit-depth by using an image previously decoded at the second bit-depth, and generating the prediction block of the current block by changing the generated prediction block of the second bit-depth to the first bit-depth. The first bit-depth is higher than the second bit-depth.
