Abstract

Un dispositivo de codificación de video, tal como un codificador de video o un decodificador de video, puede ser configurado para codificar un mensaje de información de mejora suplementaria (SEI) de la sincronicidad de una sub-imagen asociado con una primera unidad de decodificación (DU) de una unidad de acceso (AU). El dispositivo de codificación de video además puede codificar una duración entre el tiempo de eliminación del buffer de la imagen codificada (CPB) de una segunda DU de la AU en el orden de decodificación y el tiempo de eliminación del CPB de la primera DU en el mensaje SEI de la sub-imagen. El dispositivo de codificación de video además puede derivar un tiempo de eliminación del CPB de la primera DU sobre la base al menos en parte del mensaje SEI de sincronicidad de la sub-imagen.
