Abstract
Se proporciona un método de decodificación de imágenes de un flujo de bits. El método incluye la identificación de un punto de recuperación en el flujo de bits desde una indicación de punto de recuperación. El punto de recuperación especifica una posición de inicio en el flujo de bits para decodificar el conjunto de imágenes. Además, el método incluye la decodificación de la indicación del punto de recuperación para obtener un conjunto decodificado de elementos de sintaxis. Además, el método incluye la derivación de información para generar un conjunto de imágenes de referencias no disponibles del conjunto decodificado de elementos de sintaxis antes de que cualquier dato de imagen codificada sea analizado por un decodificador. Además, el método incluye la generación del conjunto de imágenes de referencia no disponibles según la información derivada. Además, el método incluye la decodificación del conjunto de imágenes después de la generación del conjunto de imágenes de referencia no disponibles. También se proporcionan métodos realizados por un codificador.
