Abstract

Un método de generar una matriz de cuantificación que se utiliza en un paso de cuantificación inversa, decodificando una matriz de cuantificación truncada codificada, incluyendo el método: recibir un tren de bits incluyendo la matriz de cuantificación truncada codificada que se obtiene codificando una matriz de cuantificación truncada, donde la matriz de cuantificación truncada se genera truncando una matriz de cuantificación que tiene una pluralidad de elementos de cuantificación, y la matriz de cuantificación truncada codificada tiene bits alineados en el orden de: bits obtenidos codificando elementos de cuantificación incluidos en la matriz de cuantificación truncada y bits obtenidos codificando un código de fin; decodificar la matriz de cuantificación truncada codificada hasta que se lean los bits correspondientes al código de fin para recuperar la pluralidad de elementos de cuantificación y reformarlos en la matriz de cuantificación truncada; y generar una matriz de cuantificación completa usando la matriz de cuantificación truncada reformada obteniendo elementos de cuantificación adicionales que se añaden a los elementos de cuantificación de la matriz de cuantificación truncada reformada para completarla.
