Abstract

Un método para mapear una pluralidad de canales de entrada de una configuración de canales de entrada con los canales de salida de una configuración de canales de salida comprende producir una serie de reglas asociadas a cada canal de entrada de la pluralidad de canales de entrada, donde las reglas definen diferentes mapeos entre el canal de entrada y una serie de canales de salida asociados. Por cada canal de entrada de la pluralidad de canales de entrada, se accede a una regla asociada al canal de entrada, se realiza una determinación de si la serie de canales de salida definida en la regla a que se ha accedido está presente en la configuración de los canales de salida, y se selecciona la regla a que se ha accedido si la serie de canales de salida definida en la regla a que se ha accedido está presente en la configuración de los canales de salida. Se mapean los canales de entrada con los canales de salida de acuerdo con la regla seleccionada.
