Abstract
Métodos para generar una paleta de conjuntos de coeficientes de filtro de retroalimentación (IIR) y utilizar la paleta para configurar (por ejemplo, actualización adaptiva) un filtro de predicción que incluye un filtro de retroalimentación y un sistema para realizar cualquiera de los métodos. Ejemplos del sistema incluyen un codificador, que comprende un filtro de predicción y configura para codificar datos indicativos de una señal de forma de onda (por ejemplo, muestras de una señal de audio), y un descodificador. En algunas modalidades, el filtro de predicción se incluye en un codificador operable para generar (y estimar a un descodificador) datos codificados incluyendo datos de coeficientes filtro indicativos del conjunto de coeficientes IIR selectos con los cuales el filtro de predicción se configura durante generación de los datos codificados. En algunas modalidades se restringe la sincronización con la cual la actualización adaptativa de configuración de filtro de predicción ocurre o se permita que ocurra (por ejemplo, para optimizar la eficiencia de codificación de predicción).
