Abstract

L'invention concerne un procédé et un système de gestion de référencement cyclique, un procédé et un système d'analyse, et un support d'enregistrement lisisble par ordinateur stockant un programme pour mettre en oeuvre lesdits procédés. Le procédé de gestion de référencement cyclique, qui peut se produire par application de références mutuelles de biens enregistrés dans un fichier de contrôle de biens exécuté dans un environnement d'application multimédia, consiste à: détecter un référencement cyclique générateur de biens; et ignorer le référencement cyclique générateur de biens. Selon les procédés et les systèmes de l'invention, un référencement cyclique pouvant survenir dans un fichier pour contrôler de biens peut être détecté et traité de sorte que le système puisse être empêché d'entrer dans une boucle indéfinie ou de provoquer une opération erronée.
