(EN) INTERACTION BETWEEN INTRA BLOCK COPY MODE AND INTER PREDICTION TOOLS
(FR) INTERACTION ENTRE UN MODE DE COPIE INTRABLOC ET DES OUTILS D'INTERPRÉDICTION
Abstract
(EN)
The present disclosure relate to interaction between intra block copy mode and inter prediction tools A method for video processing is provided, including: determining that an Intra-Block-Copy (IBC) mode is applied to a current video block of a video, wherein in the IBC mode, at least one reference picture used by the current video block is a current picture where the current video block is located in; making a decision regarding a disabling of a specific coding mode for the current block; performing, based on the decision, a conversion between the current video block and the bitstream representation; wherein the specific coding mode uses a motion vector and a non-current picture to derive a prediction of a video block.

La présente invention concerne l'interaction entre un mode de copie intrabloc et des outils d'interprédiction. Un procédé de traitement vidéo est décrit, comprenant les étapes consistant à : déterminer qu'un mode de copie intrabloc (IBC) est appliqué à un bloc vidéo courant d'une vidéo, au moins une image de référence utilisée par le bloc vidéo courant étant, dans le mode IBC, une image courante où se situe le bloc vidéo courant ; prendre une décision concernant la désactivation d'un mode de codage spécifique pour le bloc courant ; réaliser, sur la base de la décision, une conversion entre le bloc vidéo courant et la représentation de flux binaire, le mode de codage spécifique utilisant un vecteur de mouvement et une image non courante pour déduire une prédiction d'un bloc vidéo.
