Abstract: front page image
(EN)The present invention relates to a method and apparatus for processing video signals, the method comprising: receiving a video signal; decoding a current frame of the video signal in block units to generate a restored frame; and acquiring first and second flags to acquire a filter coefficient which is adaptively determined from the video signal for each slice on the basis of flag information, or performing deblocking filtering with a predetermined filter coefficient. Moreover, the present invention relates to a video signal processing method which includes an inter-frame prediction method that efficiently determines a motion vector to perform motion prediction, as well as a method for performing inter-frame prediction for a residual image. The method for processing video signals according to the present invention can increase the compression encoding efficiency of a video signal by performing accurate motion prediction and residual image prediction, and can improve the quality of a restored image by removing distortion which occurs when restoring an image and performing a filtering operation for restoring an image that is nearly identical to the original image.
(FR)L'invention concerne un procédé et un appareil destinés à traiter des signaux vidéo. Ledit procédé consiste à : recevoir un signal vidéo ; décoder une trame en cours de signal vidéo dans des unités de bloc pour générer une trame restaurée ; et acquérir un premier et un second drapeau pour obtenir un coefficient de filtre qui est déterminé de manière adaptative à partir du signal vidéo pour chaque tranche sur la base d'informations de drapeau, ou exécuter un filtrage de déblocage au moyen d'un coefficient de filtre prédéterminé. L'invention concerne également un procédé de traitement de signal vidéo qui inclut un procédé de prédiction inter-trames qui détermine efficacement un vecteur de mouvement pour effectuer une prédiction de mouvement ainsi qu'un procédé d'exécution de prédiction inter-trames pour une image résiduelle. Selon l'invention, le procédé de traitement de signaux vidéo permet d'augmenter l'efficacité d'un codage par compression d'un signal vidéo par exécution d'une prédiction de mouvement précise et d'une prédiction d'image résiduelle, et d'améliorer la qualité d'une image restaurée par suppression des distorsions qui peuvent se produire lors de la restauration d'une image et exécution d'une opération de filtrage pour restaurer une image qui est presque identique à l'image d'origine.
(KO)본 발명은 비디오 신호를 수신하는 단계; 상기 비디오 신호 내의 현재 프레임을 블록 단위로 복호화하여 복원된 프레임을 생성하는 단계; 제 1플래그 및 제 2플래그를 획득하여 플래그 정보에 기반하여 비디오 신호로부터 슬라이스마다 적응적으로 결정된 필터 계수를 획득하거나, 기결정된 필터 계수를 이용하여 디블록킹 필터링을 수행하는 단계를 포함하는 비디오 신호 처리 방법 및 장치가 개시된다. 또한 본 발명에서는 효율적으로 모션 벡터를 결정하여 움직임 예측을 수행하는 화면간 예측 방법 및 레지듀얼 영상에 대한 화면간 예측 수행 방벙을 포함하는 비디오 신호 처리 방법이 개시된다. 본 발명에 따르면 비디오 신호처리 방법에 따르면 정확한 움직임 예측 및 레지듀얼 영상에 대한 예측을 수행함으로써, 비디오 신호의 압축 부호화 효율을 높이고, 영상 복원시 발생하는 왜곡을 제거하고 원 영상에 가깝게 복원할 수 있는 필터링 연산을 수행함으로써, 복원 영상의 품질을 향상시킬 수 있다.
