Abstract
(EN)
Video decoder configured to decode a video comprising a plurality of pictures from a video data stream by decoding each picture from one or more video coding units within an access unit of the video data stream which is associated with the respective picture; read a substitute coding unit type from a parameter set unit of the video data stream; for each predetermined video coding unit, read a coding unit type identifier (100) from the respective video coding unit; check whether the coding unit identifier identifies a coding unit type out of a first subset of one or more coding unit types (102) or out of a second subset of coding unit types (104), if the coding unit identifier identifies a coding unit type out of the first subset of one or more coding unit types, attribute the respective video coding unit to the substitute coding unit type; if the coding unit identifier identifies a coding unit type out of the second subset of coding unit types, attribute the respective video coding unit to the coding unit type out of the second subset of coding unit types identified by the coding unit identifier.

La présente invention concerne un décodeur vidéo configuré pour décoder une vidéo comprenant une pluralité d'images à partir d'un flux de données vidéo, par le décodage de chaque image à partir d'une ou de plusieurs unités de codage vidéo à l'intérieur d'une unité d'accès du flux de données vidéo qui est associé à l'image respective ; la lecture d'un type d'unité de codage de substitution à partir d'une unité d'ensemble de paramètres du flux de données vidéo ; pour chaque unité de codage vidéo prédéterminée, la lecture d'un identifiant de type d'unité de codage (100) à partir de l'unité de codage vidéo respective ; la vérification si l'identifiant d'unité de codage identifie un type d'unité de codage parmi un premier sous-ensemble d'un ou plusieurs types d'unités de codage (102) ou un second sous-ensemble de types d'unités de codage (104), si l'identifiant d'unité de codage identifie un type d'unité de codage parmi le premier sous-ensemble des un ou plusieurs types d'unités de codage, l'attribution de l'unité de codage vidéo respective au type d'unité de codage de substitution ; si l'identifiant d'unité de codage identifie un type d'unité de codage parmi le second sous-ensemble de types d'unités de codage, l'attribution de l'unité de codage vidéo respective au type d'unité de codage parmi le second sous-ensemble de types d'unités de codage identifiés par l'identifiant d'unité de codage.
