Hauptman Ham, LLP
Method and device for subband coding frequency conversion unit, and method and device for image encoding/decoding using same
A method performed by an apparatus for decoding a video, includes: generating a predicted block by predicting a current block to be decoded; reconstructing frequency coefficients in a frequency conversion unit by decoding a bitstream, to generate a frequency conversion block having a size of the frequency conversion unit; inversely transforming the frequency conversion block by using a transform size identical to the size of the frequency conversion unit, to reconstruct a residual block; and adding the reconstructed residual block to the predicted block.
