Abstract

Se puede proporcionar un nuevo servicio como que mantiene la compatibilidad con un receptor de audio relacionado, sin deteriorar un eficiente uso de una banda de transmisión. Se genera un número predeterminado de flujos de audio que tienen primeros datos codificados y segundos datos codificados que están relacionados con los primeros datos codificados, y se transmite un contenedor en un formato predeterminado que incluye estos flujos de audio. El número predeterminado de flujos de audio se generan de modo que los segundos datos codificados se descartan en un receptor que no es compatible con los segundos datos codificados.
