Abstract

L'invention concerne un système combiné de réception de télévision et d'informatique, qui comprend au moins un dispositif d'utilisateur, assurant la conversion des signaux de télédiffusion transmis dans un réseau de télédiffusion numérique. Les signaux comportent un guide de programme électronique contenant des informations relatives aux programmes de télévision. L'invention concerne également un procédé relatif à la fourniture d'informations sur les programmes de télévision, qui comprend les étapes suivantes: récupération de termes de recherche sur des étiquettes de script ou dans un texte de page d'accueil (HTML), via un réseau informatique (Internet ou Intranet, par exemple), exploration de guide de programme électronique à l'aide des termes de recherche récupérés, puis fourniture et présentation d'une série de résultats de recherche sur les programmes de télévision.
