Abstract

La présente invention concerne un procédé pour la distribution sécurisée de flux audiovisuels numériques selon un format standard, normalisé ou propriétaire, lesdits flux sur lesquels on procède, avant la transmission à l'équipement destinataire, à une séparation (2) du flux en deux parties pour générer un flux principal modifié (14), présentant le format du flux original, et une information complémentaire (3) d'un format quelconque, comportant les informations numériques aptes à permettre la reconstruction du flux original, caractérisé en ce que l'on transmet par voies séparées pendant la phase de distribution ledit flux principal modifié (12) à partir d'un serveur de distribution (13) et ladite information complémentaire vers ledit équipement destinataire (11) depuis un serveur central sécurisé (4) en passant par au moins un serveur local reliant ledit équipement destinataire (11) audit serveur local via au moins un point d'accès (11).
