Title (EN) METHOD FOR INDUCING MOTION INFORMATION IN MULTILAYER STRUCTURE AND APPARATUS USING SAME
(FR) PROCEDE POUR INDUIRE DES INFORMATIONS DE MOUVEMENT DANS UNE STRUCTURE MULTICOUCHE ET APPAREIL L'UTILISANT
(KO) 멀티 레이어 구조에 있어서 움직임 정보의 유도 방법 및 이를 이용하는 장치
Abstract: front page image
(EN)The present invention relates to a method for encoding a video and a method for decoding a video in a multilayer structure, and an apparatus using same. The method for decoding the video according to the present invention comprises the steps of: specifying a current layer reference location for specifying a current block from a current layer; specifying a reference layer reference location corresponding to the reference location of the current layer, from the reference layer; inducing motion information from the reference layer reference location, based on the size of motion information saving units; and scaling the induced motion information and inducing same into a motion vector used for recovering a picture in the current layer.
(FR)La présente invention concerne un procédé pour coder une vidéo et un procédé pour décoder une vidéo dans une structure multicouche, et un appareil les utilisant. Le procédé pour décoder la vidéo selon la présente invention comprend les étapes consistant à : spécifier un emplacement de référence de couche courante pour spécifier un bloc courant à partir d'une couche courante; spécifier un emplacement de référence de couche de référence correspondant à l'emplacement de référence de la couche courante, à partir de la couche de référence; induire des informations de mouvement à partir de l'emplacement de référence de couche de référence, sur la base de la taille d'unités de sauvegarde d'informations de mouvement; et mettre à l'échelle les informations de mouvement induites et inclure celles-ci dans un vecteur de mouvement utilisé pour récupérer une image dans la couche courante.
(KO)본 발명은 멀티 레이어 구조에서의 비디오 인코딩 방법, 비디오 디코딩 방법과 이를 이용하는 장치에 관한 것으로서, 본 발명에 따른 비디오 디코딩 방법은 현재 레이어에서 현재 블록을 특정하는 현재 레이어 기준 위치를 특정하는 단계, 참조 레이어에서 상기 현재 레이어 기준 위치에 대응하는 참조 레이어 기준 위치를 특정하는 단계, 상기 참조 레이어 기준 위치에서 움직임 정보 저장 단위의 크기를 기반으로 움직임 정보를 유도하는 단계 및 상기 유도된 움직임 정보를 스케일링하여 상기 현재 레이어에 픽처 복원에 이용하는 움직임 벡터로서 유도하는 단계를 포함한다.
