Abstract

Esta invencion se refiere a un metodo, dispositivo y producto de aplicacion de software para la cuantificacion de vectores de nivel-N, en donde N puede ser seleccionado antes de la cuantificacion a partir de un conjunto de al menos dos valores predefinidos que son mas pequenos o iguales a un numero maximo predefinido de niveles-M. un valor de reproduccion para cada vector es seleccionado a partir del libro de codigos de n nivel-N de N vectores de reproduccion que son, para cada N en el conjunto de al menos dos valores predefinidos, representados por los primeros N vectores de reproduccion del libro de codigos de union. La invencion ademas se refiere a un metodo, dispositivo y producto de aplicacion de software para la recuperacion de los vectores de reproduccion para vectores que han sido cuantificados de nivel-N, a un sistema para la transferencia de representaciones de vectores, a un metodo, dispositivo y producto de aplicacion de software para la determinacion de un libro de codigos de union, y a un libro de codigos de union por si mismo.
