Title
(EN) ADAPTIVE BLOCK UPDATE OF UNAVAILABLE REFERENCE FRAMES USING EXPLICIT AND IMPLICIT SIGNALING
(FR) MISE À JOUR ADAPTATIVE DE TRAMES DE RÉFÉRENCE INDISPONIBLES PAR BLOC À L’AIDE D’UNE SIGNALISATION EXPLICITE ET IMPLICITE
Abstract
(EN)
A decoder includes circuitry configured to receive a current block, determine the current block is a block for updating an unavailable reference frame based on the current block, and update the unavailable reference frame using the current block. Related apparatus, systems, techniques and articles are also described.
(FR)
Un décodeur comprend des circuits configurés pour recevoir un bloc actuel, déterminer que le bloc actuel est un bloc destiné à la mise à jour d’une trame de référence indisponible sur la base du bloc actuel, et mettre à jour la trame de référence indisponible à l’aide du bloc actuel. La présente invention concerne en outre un appareil, des systèmes, des techniques et des articles associés.
