Abstract

La présente invention concerne un procédé et système de programmation de ressources d'unités de commande multipoint (Multipoint Control Unit, MCU), appliqués à un système de vidéoconférence comportant des MCU multiples en cascade. Le procédé comporte les étapes consistant : en premier lieu, à sélectionner une par une les MCU et à attribuer les terminaux jusqu'à ce que tous les terminaux à attribuer aient été attribués; caractérisé en ce que, pour la MCU sélectionnée chaque fois, les étapes suivantes sont réalisées : réserver des ressources de M interfaces en cascade de la MCU, M étant inférieur à une valeur prédéfinie; attribuer des terminaux à la MCU jusqu'à ce que les ressources autres que les ressources de réservation soient occupées; effectuer la validation de ressources pour la MCU, en configurant une MCU maîtresse; en second lieu, déterminer si N, le nombre de MCU sélectionnées, est égal à M+1; si c'est le cas, achever la programmation des ressources des MCU. Selon la solution technique ci-dessus apportée par la présente invention, le problème de l'utilisation réduite de la programmation des ressources lorsque des MCU multiples sont placées en cascade pour mener une vidéoconférence selon la technique antérieure est résolu, de sorte que l'interface en cascade peut être réservée de manière souple, le gaspillage des ressources pendant la procédure de programmation étant par conséquent réduit.
