Abstract
The present disclosure provides an apparatus for encoding a video including: a prediction unit to generate a predicted block of a current block; a subtraction unit to generate a residual block by subtracting the predicted block from the current block; a transformer to transform the residual block into a frequency transform block by performing different transform methods on different transform units; a quantization unit to quantize the frequency transform block to generate a quantized frequency transform block; and a bitstream generator to encode the quantized frequency transform block into a bitstream.
