Abstract

Un proceso de decodificación que comprende: el escalado de un bloque de coeficientes utilizando un factor de escalado determinado para cada coeficiente mediante el cálculo de un índice para cada coeficiente y la indexación de una tabla de consulta (LUT) usando dicho índice, en el que el índice se basa en el parámetro de cuantificación, el tamaño del bloque de coeficientes y la posición de cada coeficiente dentro del bloque; y la aplicación de una transformada al bloque de coeficientes escalados.
