Abstract

Un decodificador de video para decodificar un video de un flujo de datos está configurado para decodificar una indicación del flujo de datos la cual es válida para una secuencia de imágenes del video, e indica que las imágenes RASL dentro de la secuencia de imágenes están codificadas de una manera que excluye un conjunto predeterminado de una o más herramientas de codificación.
