Title
(EN) FLAG INDICATION METHOD IN INTRA BLOCK COPY MODE
(FR) PROCÉDÉ D'INDICATION DE DRAPEAU DANS UN MODE DE COPIE À L'INTÉRIEUR DES BLOCS
Abstract
(EN)
The present disclosure relate to flag indication method in intra block copy mode. A method for video processing is provided, including: determining whether an Intra Block Copy (IBC) mode, in which at least one reference picture used by the current video block is identical to a picture in which the current video block is located, is applied for the current video block; signaling whether the IBC mode is applied for the current video block; refraining from signaling flags for a group of prediction modes based on determining that the IBC mode is applied for the current video block; and performing the conversion for the current video block based on the application of the IBC mode.

La présente invention concerne un procédé d'indication de drapeau dans un mode de copie à l'intérieur des blocs. L'invention concerne un procédé de traitement vidéo qui consiste : à déterminer si un mode de copie à l'intérieur des blocs (IBC), dans lesquels au moins une image de référence utilisée par le bloc vidéo actuel est identique à une image dans laquelle le bloc vidéo actuel est situé, est appliqué pour le bloc vidéo actuel ; à signaler si le mode IBC est appliqué pour le bloc vidéo actuel ; à s'abstenir de signaler des drapeaux pour un groupe de modes de prédiction sur la base de la détermination du fait que le mode IBC est appliqué pour le bloc vidéo actuel ; à effectuer la conversion pour le bloc vidéo actuel sur la base de l'application du mode IBC.
