Abstract

L'invention porte sur: un appareil de production de flux de transport, sur un appareil de démultiplexage de paquets turbo et sur les méthodes associées. L'appareil de production de flux de transport comporte: un codeur RS (de Reed Solomon) de données turbo en données turbo RS; un entrelaceur des données turbo RS; un duplicateur d'adjonction d'insertion de parité aux données turbo entrelacées; et un multiplexeur multiplexant des données normales et les données turbo traitées par le duplicateur pour produire un flux de transport. On obtient ainsi des performances de réception améliorée dans un système AVSB (avancé à bande latérale résiduelle).
