Abstract

La présente invention a trait à un procédé et un dispositif permettant la gestion d'un support d'enregistrement comportant des données de diffusion numérique, ledit ensemble comprenant une information de diffusion et une information de navigation. Le dispositif est caractérisé en ce qu'il comporte: une mémoire cache permettant de mémoriser une information de diffusion lue à partir du support d'enregistrement et une structure de données comprenant au moins des données incluses dans l'information de navigation associée à cette information de diffusion; un moyen de gestion de l'information de diffusion se trouvant dans la mémoire cache, afin d'effacer l'information de diffusion et la structure de données qui y est associée, qui se trouvent dans la mémoire cache, et afin d'effectuer la lecture des données de diffusion numérique à partir du support d'enregistrement en vue d'inscrire l'information de diffusion correspondante et la structure de données qui y est associée dans ladite mémoire cache.
