Abstract

Se describen métodos y sistemas para escalabilidad de velocidad de cuadros. Se proporciona soporte para secuencias de video de entrada y salida con velocidad de cuadros variable y ángulo de obturación variable a través de escenas, o para secuencias de video de entrada con velocidad de cuadros de entrada y ángulo de obturación de entrada fijos, pero permitiendo que un decodificador genere una salida de video a una velocidad de cuadros de salida y ángulo de obturación diferentes a los valores de entrada correspondientes. También se presentan técnicas que permiten que un decodificador decodifique de manera más computacionalmente eficiente una velocidad de cuadros y ángulo de obturación objetivo retrocompatibles específicos entre aquellos permitidos.
