Title
(EN) MOST PROBABLE MODE SIGNALING WITH MULTIPLE REFERENCE LINE INTRA PREDICTION
(FR) SIGNALISATION DE MODE LE PLUS PROBABLE AVEC PRÉDICTION INTRA DE LIGNE DE RÉFÉRENCE MULTIPLE
Abstract
(EN)
A most probable mode flag is context encoded in an encoder using multiple reference lines. In a corresponding decoder, the most probable mode flag is always decoded regardless of the value of a multiple reference line index flag. When multiple reference line index is nonzero, a context is used in parsing of the most probable mode flag.
(FR)
Un drapeau de mode le plus probable est codé dans le contexte dans un codeur utilisant de multiples lignes de référence. Dans un décodeur correspondant, le drapeau de mode le plus probable est toujours décodé indépendamment de la valeur d'un drapeau d'indice de ligne de référence multiple. Lorsque l'indice de ligne de référence multiple est non nul, un contexte est utilisé lors de l'analyse du drapeau de mode le plus probable.
