Abstract
Se proporcionan un método para decodificar un flujo de bits de video codificado implementado por un decodificador de video. El método incluye el decodificador de video que determina si un valor para un primer indicador se proporciona por una entrada externa; establecer un primer indicador igual al valor proporcionado por la entrada externa y un segundo indicador igual al valor del primer indicador para impedir que una imagen de actualización de decodificación gradual (GDR) se genere cuando el valor para el primer indicador se proporciona por la entrada externa; decodificar la imagen GDR; y almacenar la imagen GDR en una memoria intermedia de imágenes decodificadas (DPB).
