Beschreibung
Zusammenfassung:	An image coding/decoding method and device are provided. Disclosed is an image decoding method comprising the steps of: acquiring a bitstream including a predetermined syntax element; performing, on the predetermined syntax element, at least one from among a determination of a context model, a probability update and a determination of a probability interval; and arithmetically decoding the predetermined syntax element on the basis of the performance results. La présente invention concerne un procédé et un dispositif de codage/décodage d'images. L'invention concerne un procédé de décodage d'images comprenant les étapes suivantes : acquérir un train de bits comprenant un élément de syntaxe prédéterminé ; effectuer, sur l'élément de syntaxe prédéterminé, au moins l'une des opérations suivantes : une détermination d'un modèle de contexte, une mise à jour d'une probabilité et une détermination d'un intervalle de probabilité ; et effectuer le décodage arithmétique de l'élément de syntaxe prédéterminé sur la base des résultats de performance. 영상 부호화/복호화 방법 및 장치가 제공된다. 본 개시의 영상 복호화 방법은 소정의 구문요소를 포함하는 비트스트림을 획득하는 단계; 상기 소정의 구문요소에 대한 문맥 모델의 결정, 확률 업데이트 및 확률 구간의 결정 중 적어도 하나를 수행하는 단계; 및 상기 수행 결과에 기초하여 상기 소정의 구문요소를 산술 복호화하는 단계를 포함한다.
