Abstract
(EN)
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information of a current block from a coded video bitstream. The prediction information is indicative of a subset of inter prediction modes associated with a merge flag being false. Then, the processing circuitry decodes at least an additional flag that is used for selecting a specific inter prediction mode from the subset of inter prediction modes. Further, the processing circuitry reconstructs samples of the current block according to the specific inter prediction mode.

Certains aspects de l'invention concernent des procédés et des appareils de codage/décodage vidéo. Dans certains exemples, un appareil de décodage vidéo comprend des circuits de réception et des circuits de traitement. Les circuits de traitement décodent des informations de prédiction d'un bloc actuel à partir d'un flux binaire vidéo codé. Les informations de prédiction indiquent un sous-ensemble de modes d'inter-prédiction associés à un drapeau de fusion qui est faux. Ensuite, les circuits de traitement décodent au moins un drapeau supplémentaire qui est utilisé pour sélectionner un mode d'inter-prédiction spécifique à partir du sous-ensemble de modes d'inter-prédiction. En outre, les circuits de traitement reconstruisent des échantillons du bloc actuel selon le mode d'inter-prédiction spécifique.
