Title (EN) COEFFICIENT LEVEL CODING IN VIDEO CODING
(FR) CODAGE DE NIVEAU DE COEFFICIENT DANS UN PROCESSUS DE CODAGE VIDÉO
Abstract:
(EN) A video coder, such as a video encoder or a video decoder, uses a first Rice parameter derivation method and a second Rice parameter derivation method for coding coefficient levels of the TU. The first Rice parameter derivation method is a statistics-based derivation method. The second Rice parameter derivation method is a template-based derivation method.
(FR) Un codeur vidéo, tel qu'un encodeur vidéo ou un décodeur vidéo, utilise un premier procédé de dérivation de paramètre de Rice et un second procédé de dérivation de paramètre de Rice pour coder des niveaux de coefficient de la TU. Le premier procédé de dérivation de paramètre de Rice est un procédé de dérivation basé sur des statistiques. Le second procédé de dérivation de paramètre de Rice est un procédé de dérivation basé sur un modèle.
