Abstract
Un sistema de difusión de audio directa satelital incluye una pluralidad de enlaces de acceso en múltiplex de división de frecuencia ("FDMA") uniformes de velocidad fija y un enlace de salida o descenso en múltiplex de tiempo compartido o división temporal ("TDM"). Los canales de audio de fuente pueden ser divididos entre y transmitidos a través de un numero seleccionable de enlaces de acceso de velocidad fija de modo que se tenga calidad de audio seleccionable en el receptor. Los enlaces de acceso en múltiplex de división de frecuencia ("FDMA") de velocidad fija incluyen información que designan a canales relacionados como conteniendo información de fuente relacionada. El procesamiento de banda de base da borde del satélite selecciona canales de información de enlace de acceso para su inclusión en ningún, en un o en múltiples enlaces de salida o descenso en múltiplex de tiempo compartido o división temporal. La información de audio transmitida puede estar encriptada, y se puede descargar la autorización a los receptores para permitir el desencriptada para servicio de abonado pagado.
