Abstract: front page image
(EN)The present invention provides a method for decoding a video signal, comprising the steps of: extracting a prediction mode for a current block from the video signal; generating a prediction block in a spatial domain according to the prediction mode; acquiring a transformed prediction block by transforming the prediction block; updating the transformed prediction block by using a correlation coefficient or a scaling coefficient; and generating a reconstructed block on the basis of the updated transformed prediction block and a residual block.
(FR)La présente invention concerne un procédé de décodage d'un signal vidéo, comprenant les étapes suivantes : extraire un mode de prédiction pour un bloc actuel à partir du signal vidéo ; produire un bloc de prédiction dans un domaine spatial selon le mode de prédiction ; acquérir un bloc de prédiction transformé par transformation du bloc de prédiction ; mettre à jour le bloc de prédiction transformé en utilisant un coefficient de corrélation ou un coefficient de mise à l'échelle ; et produire un bloc reconstruit en fonction du bloc de prédiction transformé mis à jour et d'un bloc résiduel.
(KO)본 발명은, 비디오 신호를 디코딩하는 방법에 있어서, 상기 비디오 신호로부터 현재 블록에 대한 예측 모드를 추출하는 단계; 상기 예측 모드에 따라 공간 도메인 상의 예측 블록(prediction block)을 생성하는 단계; 상기 예측 블록에 대해 변환(transform)을 수행함으로써 변환된 예측 블록(transformed prediction block)을 획득하는 단계; 상관 계수(correlation coefficient) 또는 스케일링 계수(scaling coefficient)를 이용하여 변환된 예측 블록(transformed prediction block)을 업데이트하는 단계; 및 상기 업데이트된 변환된 예측 블록(transformed prediction block)과 차분 블록에 기초하여 복원 블록을 생성하는 단계를 포함하는 것을 특징으로 하는 방법을 제공한다.
