Abstract

El presente documento describe un método (500) para generar un flujo de bits (101), donde el flujo de bits (101) comprende una secuencia de supertramas (400) para una secuencia de tramas de una señal de audio inmersivo (111). El método (500) comprende, repetidamente para la secuencia de supertramas (400), insertar (501) datos de audio codificados (206) para una o más tramas de una o más señales de canal de mezclado descendente (203) derivadas de la señal de audio inmersivo (111), en campos de datos (411, 421, 412, 422) de una supertrama (400); e insertar (502) metadatos (202, 205) para reconstruir una o más tramas de la señal de audio inmersivo (111) de los datos de audio codificados (206), en un campo de metadatos (403) de la supertrama (400).
