Abstract

Les modes de réalisation de la présente invention concernent un procédé pour enregistrer de la vidéo pour un appel d'un terminal de visiophonie ainsi qu'un terminal de visiophonie. Selon l'invention, le procédé comprend : un premier terminal de visiophonie envoie un message de réponse de demande de l'état de sonnerie à un deuxième terminal de visiophonie après avoir reçu un message de demande d'appel envoyé par le deuxième terminal de visiophonie ; après la réception par le premier terminal de visiophonie des données vidéo envoyées par le deuxième terminal de visiophonie, si la durée de la sonnerie du premier terminal de visiophonie dépasse une durée prédéfinie et que l'appel n'aboutit pas, les données vidéo et un identifiant du deuxième terminal de visiophonie sont enregistrés et les données vidéo enregistrées sont stockées dans un fichier vidéo. Avec la présente invention, dans le cas où un appel n'aboutit pas, les données vidéo et le numéro d'appel du correspondant peuvent être enregistrés, ce qui facilite la lecture d'une vidéo corrélative au moment de l'acquisition des appels manqués et améliore le service à l'abonné.
