  • the set top box checks 42 the incoming call and if the caller is in the authorised list, the call is let through otherwise the call is disregarded 43.
  • the set top box checks 44 whether the TV is on or the bracelet is nearby; if so the call is put through.
  • the TV may be turned on automatically.
  • the call is put through 45 otherwise the caller is informed 46 that there is no user in nearby.
  • the TV program is interrupted and the image of the caller is screened 47.
  • the set top box starts recording 48 the current TV program. From now on the caller has the total control over the system and can maintain the call and control the set top box. The call is terminated from the caller side and the called person cannot terminate the call. If the caller is not on the list, the receiver must accept the call, e.g. using the bracelet.

Abstract

La présente invention concerne un système d'appel vidéo/audio destiné à permettre une communication entre un premier et un second utilisateur. La communication comprend : un flux de données comprenant des signaux de commande, ainsi que des données vidéo et audio. Le système se compose d'un premier et d'un second système de communication séparés géographiquement, dans lequel le premier utilisateur commande les deux systèmes de communication, et où chaque système de communication est doté d'une caméra vidéo, d'un micro et d'une connexion de réseau permettant de connecter le système de communication au réseau. La connexion de réseau est utilisée pour envoyer un flux de données initiant un appel à partir du premier système de communication vers le second système de communication, et pour transmettre le flux de données entre le premier et le second système de communication une fois que l'appel est initié.
