Abstract

En general, se describen técnicas para la señalización de capas para la codificación escalable de datos de audio ambisónicos de orden superior. Un dispositivo que comprende una memoria y un procesador se pueden configurar para llevar a cabo las técnicas. La memoria se puede configurar para almacenar el flujo de bits. El procesador se puede configurar para la obtención, a partir del flujo de bits, de una indicación de un número de capas especificadas en el flujo de bits, y la obtención de las capas del flujo de bits con base en la indicación del número de capas.
