Abstract

L'invention concerne un système de télévision conçu pour fonctionner comme un serveur destiné à distribuer des applications autonomes diffusables vers un dispositif extérieur. L'application autonome diffusable peut être comprise dans un signal vidéo de programme de diffusion, ou dans une diffusion de train de données sur un canal de distribution de données dédié. Dans la mise en oeuvre considérée, l'application autonome diffusable est une mini-application Java, et le dispositif extérieur est activé par Java. Dans un mode de réalisation, le système de télévision stocke l'application autonome avant de la transmettre au dispositif extérieur, et affiche des informations d'identification d'application suffisantes pour informer un téléspectateur des différentes applications autonomes disponibles pouvant être téléchargées vers le dispositif extérieur. Le système de télévision comprend, de préférence, un mécanisme permettant au téléspectateur de sélectionner au moins l'une quelconque des différentes applications autonomes disponibles pouvant être téléchargée vers le dispositif extérieur. Dans un mode de réalisation particulier, le dispositif extérieur est un contrôleur distant intelligent, par exemple, le Philips «Pronto» iRCD.
