Abstract

Il est fourni un système de service vidéophonique susceptible de réaliser un service bidirectionnel basé sur une vidéo non en temps réel qui ne peut pas être fourni par le téléphone classique. Le système inclut un moyen pour décider différents supports tels que la séquence animée, les images fixes, les caractères et le son distribués en réponse d’un utilisateur du service de vidéophonique IP et leur procédé de distribution et la distribution de ces supports en tant que vidéo en continu au vidéophone IP, selon la procédure de distribution préétablie dans un serveur de distribution (50) raccordé à un réseau IP (10) auquel est fourni le service vidéophonique. Ainsi, l’utilisateur du vidéophone IP peut acquérir différentes informations de manière interactive et audiovisuelle uniquement par le fonctionnement du téléphone classique et de la communication téléphonique.
