(FR) DISPOSITIF DE CODAGE D'IMAGE ANIMÉE ET DISPOSITIF DE DÉCODAGE D'IMAGE ANIMÉE
(JA) 動画像符号化装置及び動画像復号装置
Abstract:
(EN) The definition of a flag that indicates the number of non-zero conversion coefficients in a coding unit (CU) is changed to reduce the amount of code for LAST, which indicates the position of the last non-zero conversion coefficient in the CU.
(FR) Selon l'invention, la définition d'un indicateur qui indique le nombre de coefficients de conversion non nuls dans une unité de codage (CU) est modifiée pour réduire la longueur du code pour LAST qui indique la position du dernier coefficient de conversion non nul dans la CU.
(JA) CU内の非ゼロ変換係数の個数を示すフラグの定義を変更することで、CU内の最後の非ゼロ変換係数の位置を表すLASTの符号量を削減する。
