Abstract

Se describen dispositivos de codificación y decodificación para codificar los canales de un sistema de audio que tiene al menos cuatro canales. El dispositivo de decodificación tiene un primer componente de decodificación estéreo que somete un primer par de canales de entrada a una primera decodificación estéreo, y un segundo componente de decodificación estéreo que somete un segundo par de canales de entrada a una segunda decodificación estéreo. Los resultados del primer componente de decodificación estéreo y el segundo componente de decodificación estéreo se acoplan transversalmente a un tercer componente de decodificación estéreo y un cuarto componente de decodificación estéreo, cada uno de los cuales realiza decodificación estéreo en un canal resultante del primer componente de decodificación estéreo y un canal resultante del segundo componente de decodificación estéreo.
