Abstract
Un método codificador de datos que comprende la codificación de un arreglo de valores de datos como conjuntos de datos y códigos de escape para valores no codificados por el conjunto de datos, un código de escape comprende una porción prefijo y una porción sufijo codificada no unaria que tiene una longitud, en bits, dependiente de un valor codificado por la porción prefijo de acuerdo con una relación tal que, para al menos algunos valores codificados por la porción prefijo, la longitud de la porción sufijo codificada no unaria es mayor que la longitud, en bits, de la porción prefijo.
