Title
(EN) METHOD FOR SYNTAX CONTROLLED DECODED PICTURE BUFFER MANAGEMENT
(FR) PROCÉDÉ DE GESTION DE TAMPON D'IMAGE DÉCODÉE COMMANDÉE PAR SYNTAXE
Abstract
(EN) A method and apparatus for managing a decoded picture buffer for video decoding including decoding at least one syntax element related to a reference picture stored in the decoded picture buffer; and reconstructing a current picture using the reference picture, wherein the syntax element whether the reference picture available or unavailable for future reference.
(FR) Un procédé et un appareil de gestion d'un tampon d'image décodée pour un décodage vidéo comprennent le décodage d'au moins un élément de syntaxe associé à une image de référence stockée dans le tampon d'image décodée; et de reconstruction d'une image courante à l'aide de l'image de référence, l'élément de syntaxe indiquant si l'image de référence est disponible ou indisponible pour une référence future.
