Abstract: front page image
(EN)The present invention, with respect to a method for decoding a video signal, provides a method characterized by comprising the steps of: extracting an inter-prediction mode of the current block from the video signal; generating two non-square prediction blocks by means of two movement vectors in accordance with the inter-prediction mode; acquiring two non-square prediction blocks in the frequency domain by carrying out non-square transformation on the two non-square prediction blocks; updating the two non-square prediction blocks in the frequency domain by means of a correlation coefficient or scaling coefficient; and generating a reconstructed block on the basis of the residual block and updated non-square prediction blocks in the frequency domain.
(FR)La présente invention, par rapport à un procédé de décodage d'un signal vidéo, fournit un procédé caractérisé en ce qu'il comprend les étapes suivantes : l'extraction d'un mode d'inter-prédiction du bloc courant à partir du signal vidéo ; la génération de deux blocs de prédiction non carrés au moyen de deux vecteurs de mouvement conformément au mode d'inter-prédiction ; l'acquisition de deux blocs de prédiction non carrés dans le domaine fréquentiel en effectuant une transformation non carrée sur les deux blocs de prédiction non carrés ; la mise à jour des deux blocs de prédiction non carrés dans le domaine fréquentiel au moyen d'un coefficient de corrélation ou d'un coefficient de mise à l'échelle ; et la génération d'un bloc reconstruit, sur la base du bloc résiduel et des blocs de prédiction non carrés mis à jour dans le domaine fréquentiel.
(KO)본 발명은, 비디오 신호를 디코딩하는 방법에 있어서, 상기 비디오 신호로부터 현재 블록의 인터 예측 모드를 추출하는 단계; 상기 인터 예측 모드에 따라 2개의 움직임 벡터를 이용하여 2개의 비정방형 예측 블록(non-square prediction block)을 생성하는 단계; 상기 2개의 비정방형 예측 블록에 대해 비정방형 변환을 수행함으로써 주파수 도메인 상의 2개의 비정방형 예측 블록(non-square prediction block)을 획득하는 단계; 상관 계수(correlation coefficient) 또는 스케일링 계수(scaling coefficient)를 이용하여 상기 주파수 도메인 상의 2개의 비정방형 예측 블록(non-square prediction block)을 업데이트하는 단계; 및 상기 주파수 도메인 상의 업데이트된 비정방형 예측 블록(updated non-square prediction block)과 차분 블록에 기초하여 복원 블록을 생성하는 단계를 포함하는 것을 특징으로 하는 방법을 제공한다.
