Abstract

IL EST MIS à DISPOSITION UN SYSTèME DE RADIODIFFUSION DIRECTE PAR SATELLITE QUI ASSEMBLE DES BITS DE PROGRAMMES DE RADIODIFFUSION EN INCRÉMENTS à DÉBITS PRIMAIRE, DONT PLUSIEURS D'ENTRE EUX SONT ASSEMBLÉS EN UNE TRAME. LES TRAMES SONT DIVISÉES EN SYMBOLES QUI SONT DÉMULTIPLEXÉS EN CANAUX ALTERNÉS APPARTENANT à UNE PLURALITÉ DE CANAUX à DÉBIT PRIMAIRE. LES CANAUX à DÉBIT PRIMAIRE SONT DÉMULTIPLEXÉS EN NOMBRE CORRESPONDANT DE FRÉQUENCES DE RADIODIFFUSION POUR LA TRANSMISSION VERS UN SATELLITE. LA CHARGE UTILE DE SATELLITE COMMUTE LES SYMBOLES DANS DES FLUX DE DONNÉES MULTIPLEXÉS PAR RÉPARTITION DANS LE TEMPS (MRT) . LES RÉCEPTEURS TRAITENT LES FLUX MRT à L'AIDE D'EN-TeTES DE COMMANDE DE SERVICE (SCH) QUI Y SONT INSÉRÉS PAR DES STATIONS DE RADIODIFFUSION. LES SCH FACILITENT LA TRANSMISSION DE DIFFÉRENTS COMPOSANTS DE SERVICE DANS DES TRAMES DE CANAUX DE RADIODIFFUSION, L'ASSOCIATION D'UN CANAL DE RADIODIFFUISION PRIMAIRE à UN OU PLUSIEURS CANAUX DE RADIODIFFUSION SECONDAIRES, EN UN MODE DE TRAME PAR TRAME, ET LA TRANSMISSION, AU TRAVERS D'UN CANAL DE RADIODIFFUSION, DE FLUX BINAIRES MULTITRAMES OU DE DONNÉES AUXILIAIRES QUI SONT INDÉPENDANTS D'UN SERVICE, DANS DES TRAMES CONTIGUeS OU NON CONTIGUeS.
