Abstract
(EN)
Apparatuses and methods for encoding and decoding are provided. The method includes determining whether at least one of two blocks is predicted by application of combined inter-intra prediction (CIIP), wherein the two blocks include a first block (block Q) and a second block (block P), and wherein the two blocks are associated with a boundary. The method further includes setting a boundary strength (Bs) of the boundary to a first value when at least one of the two blocks is predicted by application of CIIP; or setting a boundary strength (Bs) of the boundary to a second value when none of the two blocks is predicted by application of CIIP.
(FR)
L'invention concerne des appareils et des procédés de codage et de décodage. Le procédé consiste à : déterminer si au moins un des deux blocs est prédit en appliquant une prédiction inter-intra combinée (CIIP), les deux blocs comptant un premier bloc (bloc Q) et un second bloc (bloc P) et étant associés à une limite ; puis paramétrer une intensité (Bs) de la limite à une première valeur lorsqu'au moins un des deux blocs est prédit en appliquant une CIIP ; ou paramétrer une intensité (Bs) de la limite à une seconde valeur lorsqu'aucun des deux blocs n'est prédit en appliquant une CIIP.
