Abstract
Disclosed is a method allowing enhanced prediction of a video signal, the method comprising the steps of: entropy-decoding a neighboring block adjacent to a target block; inverse-quantizing the entropy-decoded neighboring block; acquiring the modified neighboring block by carrying out a modified inverse transform on an inverse-quantized transform coefficient vector of the neighboring block; and generating a prediction block for the target block based on the modified neighboring block, wherein the modified inverse transform applies a different scaling matrix for each pixel location reconstructed for the inverse-quantized transform coefficient vector of the neighboring block.
