Abstract

La présente invention se rapporte à un système (10) comprenant au moins un dispositif de gestion de média (2), un dispositif de stockage (6) et un dispositif d'affichage (3). Le système selon l'invention est configuré de façon à enregistrer un flux multimédia en direct dans le dispositif de stockage (6) durant une pause, et à fournir le contenu multimédia enregistré et temporellement décalé au dispositif d'affichage (3) une fois la pause terminée. Le contenu multimédia temporellement décalé est lu plus rapidement que le flux multimédia en direct, dans le but de rattraper le flux multimédia en direct, et la lecture accélérée est obtenue en augmentant la vitesse de lecture et/ou en sautant des trames. La lecture accélérée du contenu multimédia enregistré est contrôlée par le dispositif de gestion de média et/ou par l'utilisateur final via un dispositif d'entrée utilisateur (1). Quand le contenu multimédia enregistré a rattrapé le flux multimédia en direct, le flux multimédia en direct est lu sur le dispositif d'affichage.
