Abstract

L'invention concerne un procédé, un système et un client pour plate-forme à enregistrement vidéo. Lorsqu'un serveur d'enregistrement vidéo fonctionne anormalement, un client détecte s'il existe une tâche d'enregistrement vidéo exécutée ou à exécuter dans une liste de tâches d'enregistrement vidéo qui est sauvegardée en local. Le cas échéant, le client active le codeur et la vidéo est enregistrée, et le fichier vidéo est stocké localement. La solution de l'invention permet, dans le cas où le mécanisme d'enregistrement vidéo de plate-forme ne fonctionne pas côté serveur, d'introduire un mécanisme de sauvegarde mutuelle entre la plate-forme et le client. Lorsque le serveur d'enregistrement vidéo de plate-forme ne fonctionne pas et qu'il ne peut pas effectuer l'enregistrement vidéo de plate-forme, le client exécute la tâche d'enregistrement vidéo de plate-forme à la place du serveur d'enregistrement vidéo. De cette façon, l'invention peut remplir les tâches d'enregistrement vidéo avec souplesse dans le cas où le serveur d'enregistrement vidéo ne fonctionne pas, le système présentant une bonne tolérance aux défaillances.
