Abstract
A video decoding apparatus includes: a decoder to extract motion information on a current block to be decoded and a quantized frequency-transformed block from a bitstream; an inverse quantizer to reconstruct a frequency-transformed block based on inversely quantizing the quantized frequency-transformed block; an inverse transformer to reconstruct a residual block based on inversely transforming the frequency-transformed block; a predictor to determine a motion vector of the current block based on the extracted motion information, and generate a prediction block based on interpolating chroma sub-samples of a reference block referenced by the motion vector of the current block; and an adder to reconstruct the current block based on adding the reconstructed residual block and the prediction block.
