Abstract
(EN)
Aspects of the disclosure provide a method and an apparatus for video encoding/decoding. Processing circuitry of the apparatus can decode first prediction information of a first coding block in a first key picture from a coded video bitstream. The first key picture is one of multiple key pictures in a video sequence and includes a first intra coded region and a first inter coded region. When the first prediction information indicates that the first coding block is in the first intra coded region, the processing circuitry reconstructs at least one sample of the first coding block based on the first intra coded region. When the first prediction information indicates that the first coding block is in the first inter coded region, the processing circuitry reconstructs the at least one sample of the first coding block based on a region different from the first inter coded region.

Des aspects de la présente invention concernent un procédé et un appareil de codage/décodage vidéo. Des circuits de traitement de l'appareil peuvent décoder des premières informations de prédiction d'un premier bloc de codage dans une première image clé à partir d'un flux binaire vidéo codé. La première image clé est l'une de multiples images clés dans une séquence vidéo et comprend une première région intra-codée et une première région inter-codée. Lorsque les premières informations de prédiction indiquent que le premier bloc de codage est dans la première région intra-codée, le circuit de traitement reconstruit au moins un échantillon du premier bloc de codage sur la base de la première région intra-codée. Lorsque les premières informations de prédiction indiquent que le premier bloc de codage est dans la première région inter-codée, le circuit de traitement reconstruit l'au moins un échantillon du premier bloc de codage sur la base d'une région différente de la première région inter-codée.
