Title (EN) METHOD FOR ENCODING AND DECODING IMAGE INFORMATION AND DEVICE USING SAME
(FR) PROCÉDÉ DE CODAGE ET DE DÉCODAGE D'INFORMATIONS D'IMAGE ET DISPOSITIF L'UTILISANT
(KO) 영상 정보 부호화 방법 및 복호화 방법과 이를 이용한 장치
Abstract: front page image
(EN)The present invention relates to the encoding and decoding of image information. According to the present invention, the decoding method comprises the steps of: entropy-decoding received information; performing inter prediction on a current block based on the entropy-decoded information; and restoring images by using the prediction results, wherein, in the inter prediction step, a skip mode or merge mode is applied to the current block and movement information of the current block may be determined based on the movement information of a neighboring block of the current block.
(FR)L'invention se rapporte au codage et au décodage d'informations d'image, et concerne un procédé de décodage consistant à : décoder par entropie des informations reçues ; effectuer une inter-prédiction d'un bloc courant en fonction des informations décodées par entropie ; et restituer les images en utilisant les résultats d'inter-prédiction. Lors de l'étape d'inter-prédiction, un mode de saut ou un mode de fusion est appliqué au bloc courant et les informations de mouvement du bloc courant peuvent être déterminées en fonction des informations de mouvement d'un bloc voisin du bloc courant.
(KO)본 발명은 영상 정보 부호화 및 복호화에 관한 것으로서, 본 발명에 따른 복호화 방법은 수신한 정보를 엔트로피 복호화하는 단계, 상기 엔트로피 복호화한 정보를 기반으로 현재 블록에 대한 인터 예측을 수행하는 단계 및 상기 예측 결과를 이용하여 영상을 복원하는 단계를 포함하며, 상기 인터 예측 단계에서는, 상기 현재 블록에 대하여 스킵 모드 또는 머지 모드를 적용하고, 상기 현재 블록의 움직임 정보를 상기 현재 블록의 주변 블록의 움직임 정보를 기반으로 결정할 수 있다.
