Abstract
(EN)
A data processing device and data processing method, in which output systems are controlled so that digital data is outputted through only one specified output system out of the output systems in accordance with the contents of copy restriction based on management data. Therefore the digital data is not outputted through a plurality of output systems when there is copy restriction based on management data, thus properly performing data management.
(FR)
Cette invention se rapporte à un dispositif de traitement de données et à un procédé de traitement de données dans lesquels les systèmes de sortie sont commandés pour que les données numériques soient émises par un seul système de sortie spécifié parmi les systèmes de sortie, en fonction du contenu de la restriction de copie basée sur les données de gestion. Les données numériques ne sont ainsi pas émises par plusieurs systèmes de sortie, lorsqu'il existe une restriction de copie basée sur les données de gestion, ce qui permet d'effectuer correctement la gestion des données.
