Abstract

L'invention concerne un dispositif d'enregistrement de données ou un dispositif analogue permettant de protéger une image fixe contre la copie non autorisée lorsque les données musicales associées à cette image sont déplacées, et de restaurer le lien entre image et données musicales lorsque ces dernières sont retournées sur un premier support d'enregistrement. Pour réaliser ce dispositif, on enregistre sur un disque optique (DK) des données d'identification (CID) permettant d'identifier des données d'image fixe (STL) associées à un objet audio (AOB), et des données de présence (SFG) indiquant si l'objet audio (AOB) et les données d'image fixe (STL) associées à l'objet audio (AOB) sont présent sur le même disque optique (DK)
