Abstract

Selon l'invention, un système de diffusion en continu de contenu audiovisuel en temps réel transmet un contenu audiovisuel sur un inter-réseau d'une source de flux audiovisuel à une pluralité de spectateurs invités. Le système comprend un dispositif de surveillance d'application couplé à un inter-réseau pour surveiller les performances de serveurs de diffusion en continu qui reçoivent et diffusent un flux audiovisuel sur l'inter-réseau, sur la base de sa surveillance des serveurs de diffusion en continu. Le dispositif de surveillance d'application surveille également les performances de serveurs de commande et sélectionne un serveur sur la base de celles-ci pour établir une commande avec la source de flux audiovisuel et permettre la transmission du flux de la source à un serveur de diffusion en continu sélectionné et pour établir une commande de spectateurs invités pour la diffusion du flux audiovisuel d'un serveur de diffusion en continu sélectionné à un spectateur invité.
