Abstract

Se presenta un aparato para generar señales de parlantes. El aparato comprende un procesador de metadatos de objeto (110) y un renderizador de objetos (120). El renderizador de objetos (120) está configurado para recibir un objeto de audio. El procesador de metadatos de objetos (110) está configurado para recibir metadatos, que comprenden una indicación de si el objeto de audio tiene relación con la pantalla, y que además comprende una primera posición del objeto de audio. El procesador de metadatos de objetos (110) está configurado para calcular una segunda posición del objeto de audio dependiendo de la primera posición del objeto de audio y dependiendo de un tamaño de una pantalla, si en los metadatos se indica que el objeto de audio tiene relación con la pantalla. El renderizador de objetos (120) está configurado para generar las señales de parlantes dependiendo del objeto de audio y dependiendo de información de posición. El procesador de metadatos de objetos (110) está configurado para alimentar la primera posición del objeto de audio como información sobre la posición al renderizador de objetos (120), si en los metadatos se indica que el objeto de audio no está relacionado con la pantalla. El procesador de metadatos de objetos (110) está configurado para alimentar la segunda posición del objeto de audio como información sobre la posición al renderizador de objetos (120), si en los metadatos se indica que el objeto de audio tiene relación con la pantalla.
