Abstract

Es posible realizar con precisión la renderización de audio 3D incluso en un caso donde la conmutación de vistas se realiza en un lado de recepción. Se generan un primer flujo de video que tiene datos de video de una primera vista, un segundo flujo de video que tiene datos de video de una segunda vista, y un flujo de audio que tiene datos de audio de una fuente de sonido de objeto e información posicional basada en la primera vista de la fuente de sonido de objeto. Se transmite un contenedor de un formato predeterminado que incluye el primer flujo de video, el segundo flujo de video, el flujo de audio, y la información de corrección de posición para corregir la información posicional de la fuente de sonido de objeto a la información posicional basada en la segunda vista.
