Zusammenfassung:	Disclosed herein is a method of encoding a video signal, comprising receiving an original video signal; comparing the original video signal with a previously reconstructed signal; generating a correction signal to minimize a sum of a distortion component and a rate component; and entropy-encoding the correction signal that is transmitted to the decoder for video signal reconstruction, wherein the previously reconstructed signal has been inverse-transformed by additionally using a scaling diagonal matrix.
