Abstract

Un système de communication comporte un signal d'information ayant une pluralité de flux de données (72, 77, 92). Les flux de données sont modulés simultanément dans une transmission (110) par symboles, à niveaux multiples. Les flux de données peuvent avoir des protocoles de signalisation soit indépendants soit dépendants. Un moyen de transmission (105) produit les informations dans un mode de réalisation parmi une pluralité de modes de réalisation. Un premier récepteur (200) reçoit le signal d'informations, et ne traite qu'un premier flux de données destiné à des messages. Un second récepteur (300) reçoit le signal d'informations, et ne traite que le second flux de données destiné à des messages. Un troisième récepteur (400) est capable de recevoir et de traiter sélectivement une pluralité de flux de données. Selon plusieurs modes de réalisation, ledit troisième récepteur assure la sélection des flux de données.
