Abstract

La gestión de la funcionalidad de conversión ascendente de la tasa de fotogramas se mejora a través del uso de indicaciones en un flujo de bits de video que controlan tanto las subporciones de una imagen de video como los subprocesos. En lugar de una sola indicación que controla la conversión ascendente de la tasa de fotogramas, al menos una modalidad utiliza señalización adicional para determinar si un codificador o un decodificador debe implementar la conversión ascendente de la tasa de fotogramas para una porción de codificación de video particular o si implementar uno de los procesos asociados con la conversión ascendente de la tasa de fotogramas.
