Abstract

Un método de codificación de datos para la codificación de una matriz de valores de datos como conjuntos de datos y códigos de escape para los valores no codificados por los conjuntos de datos, un código de escape que comprende una porción unaria codificada y una parte no unaria codificada comprende las etapas de: Establecer un parámetro de codificación de la definición de un número mínimo de bits de una parte codificada no unaria, el parámetro de codificación está entre 0 y un límite superior predeterminado; añadir un valor de desplazamiento de 1 o más para el parámetro de codificación a fin de definir un tamaño mínimo de la porción de datos menos significativos; generar uno o más conjuntos de datos indicativos de las posiciones, en relación con la matriz de valores de datos, de valores de datos de rangos de magnitud predeterminada, a fin de codificar el valor de al menos un bit menos significativo de cada valor de datos; generar, a partir de al menos la parte de cada valor de datos no codificados por el uno o más conjuntos de datos, las respectivas porciones de datos más significativos complementarios y porciones de datos menos significativos, de tal manera que la porción de datos más significativo de un valor representa cero o más bits más significativos de esa porción, y la respectiva porción de datos menos significativo depende de un número de bits menos significativos de esa parte, el número de bits menos significativos que es mayor que o igual al tamaño mínimo de la porción de datos menos significativo; codificar los conjuntos de datos a un flujo de datos de salida; codificar las porciones de datos más significativos con la corriente de datos de salida; y la codificación de las porciones menos significativos con la corriente de datos de salida.
