Abstract
(EN)
A decoder includes circuitry configured to receive a bitstream, decode a plurality of video frames from the bitstream, determine for a current block of a current frame that a long term reference block update mode is enabled, determine a long term reference block update including pixel values and using the plurality of video frames, and update a portion of a long term reference frame with the long term reference block update. Related apparatus, systems, techniques and articles are also described.

L'invention concerne un décodeur comprenant des circuits conçus pour recevoir un flux binaire, pour décoder une pluralité de trames vidéo à partir du flux binaire, pour déterminer, pour un bloc courant d'une trame courante, qu'un mode de mise à jour de bloc de référence à long terme est activé, pour déterminer une mise à jour de bloc de référence à long terme comprenant des valeurs de pixel et utilisant la pluralité de trames vidéo, et pour mettre à jour une partie d'une trame de référence à long terme au moyen de la mise à jour de bloc de référence à long terme. La présente invention concerne également un appareil, des systèmes, des techniques et des articles associés.
