METHOD AND APPARATUS FOR PROCESSING VIDEO SIGNALS USING COEFFICIENT DERIVATION PREDICTION

摘要

The present invention provides a method for performing enhanced prediction on video signals, comprising the steps of: performing entropy decoding and dequantization on a neighboring block of a target block; performing scaling on a dequantized transform coefficient for the neighboring block by using a scaling matrix; acquiring a modified neighboring block by performing inverse transform on the scaled transform coefficient; and generating a prediction block for the target block on the basis of the modified neighboring block.
