Abstract
Se proporciona un sistema de radiodifusion directa por satélite que ensambla bits de programas de difusion en incrementos de velocidad fundamental,varios de los cuales se ensamblan en un bloque. Los bloques se dividen en símbolos quese desmultiplexan en bloques alternantes de una pluralidad decanales de velocidad fundamental. Los canales de velocidad fundamental se desmultiplexan en un numero correspondiente de frecuencias de difusion paratransmision a un satélite; undesmul tiplexor polifásico a bordo separa senales de enlace ascendente en flujos de símbolos multiplexados por division detiempo. Un desmodulador de modulacion por desplazamiento de fase a bordo desmodula los símbolos en datos digitales debanda bas e. Un aparato dealineacion de velocidades a bordo corrige diferencias de velocidades a frecuencias de base entre un reloj a bordo y los símbolos de difusion. Elequipamiento de un satélite conmuta los símbolos en flujos de datos m ultiplexados por divison de tiempo (TDM) empleando dos memorias dinámicas dealternacion y un conmutador de encaminamiento. Los receptores procesan los flujos de TDM empleando preámbulos de bloques maestros y canales de controldeintervalos, prop orcionados en los mismos por el satélite, y cabeceras de control de servicio (SCHs) proporcionadas en los mismos por estaciones dedifusion. Las SCHs sirven para el direccionamiento de receptores particulares y para serviciosmultimedia. Se prop orciona un sistema de gestion paragestionar y controlar el satélite y las estaciones de difusion.
