Abstract
Disclosed is a video encoding apparatus. The video encoding apparatus includes a prediction unit for generating a prediction block based on interpolating sub-samples of a reference block referenced by a motion vector of a current block. The video encoding apparatus further includes a subtraction unit for generating a residual block based on subtracting the prediction block from the current block and a transform unit for generating a frequency-transformed block based on transforming the residual block. The video encoding apparatus further includes a quantization unit for generating a quantized frequency-transformed block based on quantizing the frequency-transformed block and an encoding unit for encoding the quantized frequency-transformed block into a bitstream.
