Title
(EN) METHOD OF INTRA PICTURE BLOCK COPY FOR SCREEN CONTENT AND VIDEO CODING
(FR) PROCÉDÉ DE COPIE DE BLOC D'IMAGE DE TYPE INTRA À DES FINS DE CODAGE DE CONTENU D'ÉCRAN ET VIDÉO
Abstract
(EN)
A method of screen content coding (SCC) and video coding using coding modes including IntraBC mode (Intra-block copy mode) is disclosed. In one embodiment, a Merge candidate list including one or more IntraBC Merge candidates and one or more Inter Merge candidates is derived. If an IntraBC Merge candidate is selected from the Merge candidate list for the current block, the current motion information of the current block is encoded or decoded by sharing candidate motion information of the selected IntraBC Merge candidate as the current motion information of the current block, and the current block is encoded or decoded using a coded block in the current picture located according to the current motion information as an IntraBC predictor. The candidate motion information or the current motion information may include one or more elements selected from a motion information group consisting of coding mode, displacement vector and reference picture information.
(FR)
L'invention concerne un procédé de codage de contenu d'écran (SCC) et un codage vidéo au moyen de modes de codage comprenant le mode IntraBC (mode de copie de bloc intra). Dans un mode de réalisation, une liste de candidats à la Fusion comprenant un ou plusieurs candidats à la Fusion de type IntraBC et un ou plusieurs candidats à la Fusion de type Inter est dérivée. Si un candidat à la Fusion de type IntraBC est choisi dans la liste de candidats à la Fusion pour le bloc en cours, les informations de mouvement en cours du bloc en cours sont codées ou décodées par le partage des informations de mouvement en cours du candidat à la Fusion de type IntraBC sélectionné comme informations de mouvement en cours du bloc en cours, et le bloc en cours est codé ou décodé à l'aide d'un bloc codé dans l'image en cours située en fonction des informations de mouvement en cours servant de prédicteur de type IntraBC. Les informations de mouvement des candidats ou les informations de mouvement en cours peuvent comprendre un ou plusieurs éléments sélectionnés dans un groupe d'informations de mouvement constitué par le mode de codage, le vecteur de déplacement et des informations d'image de référence.
