Abstract

Transmission de données TCP/IP par l'intermédiaire d'une liaison satellite depuis une station pivot jusqu'à une pluralité d'unités à distance. Ces données, transmises sur la liaison satellite, mettent en application le protocole de diffusion vidéo numérique (DVB). On utilise un champ de l'en-tête DVB afin d'indiquer l'emplacement du début d'un nouveau paquet de données TCP/IP à l'intérieur des données DVB. L'utilisation d'un champ de l'en-tête DVB afin d'indiquer l'emplacement du début d'un nouveau paquet de données TCP/IP facilite la localisation variable de données TCP/IP à l'intérieur d'une trame DVB et, par conséquent, permet une application plus efficace de la largeur de bande DVB.
