Abstract

Se presenta un sistema de radiodifusión directa vía satélite que incluye múltiples enlaces hacia satélite, de velocidad fija, uniforme, acceso múltiple de división de frecuencia ("FDMA") y un enlace desde satélite multiplex por división de tiempo ("TDM"). Los canales de audio fuente pueden ser divididos y trasmitidos a través de un número seleccionable de enlaces de velocidad fija hacia satélite de manera de tener una calidad de audio seleccionable en el receptor. Los enlaces hacia satélite de velocidad fija FDMA incluyen información que designa canales relacionados que contienen información relacionada de la fuente. A bordo del satélite el procesamiento de banda base selecciona canales de información hacia satétite para la inclusión en ninguna, uno o múltiples enlaces TDM desde satélite. La información de audio trasmitida puede ser codificada y se puede enviar autorización a los receptores para permitir la decodificación para los servicios tarifados.
