Abstract: PURPOSE: An encoding/decoding method and an apparatus using the same are provided to increase the similarity of a prediction block which uses an original block and a skip mode. CONSTITUTION: A skip mode prediction block is generated(S300). An offset value is determined to be applied to the skip mode prediction block(S310). A skip mode block is compensated based on the calculated skip mode offset value(S320). A prediction block which is compensated as the skip mode offset value is a reconstructed block.

Abstract: PURPOSE: An encoding apparatus and method capable of multi-dimensional conversion and quantization and a decoding apparatus and method are provided to apply integer-type quantization to a difference image which is converted twice. CONSTITUTION: A first differentiator(140) removes a prediction block created by inter prediction and creates a difference image. A converting unit(151) performs the multi-dimensional conversion of the difference image. A quantization unit(153) applies integer-type quantization to the multi-dimensionally converted difference image. An entropy coding unit(157) encodes and compresses the coefficient values of the re-aligned difference image.
