Abstract
Métodos y aparato de procesamiento de datos multimedia. Los sistemas y los métodos comprenden recibir un primer conjunto de los coeficientes cuantificados que representa al menos un cuadro de video, recibir un segundo conjunto de los coeficientes cuantificados que representa el al menos un cuadro de video, y generar, utilizando el primer conjunto de los coeficientes cuantificados y el segundo conjuntos de los coeficientes cuantificados, un tercer conjunto de los coeficientes cuantificados que representa el al menos un cuadro de video. En ciertas formas de realizacion, los parámetros de cuantificacion asociados con los primeros y segundos conjuntos se utilizan en producir el tercer conjunto de los coeficientes cuantificados.
