要約
(EN)
In order to prevent content data from being illegally recorded or reproduced, information for detecting that the content data is illegally distributed or recorded is added to watermark information or other information. Two sets of WM (watermark) data, a WM1 data set and a WM2 data set are prepared. For the WM1 data, data representing that the content data is package media data or distribution data, SCMS information, data representing that the content data is recorded in a disk or a semiconductor memory, and data representing the type of disk or semiconductor memory are set. For the WM2 data, the distribution time or the year and date is set as time information representing time when the content data is recorded. According to the WM1 or WM2 data, a data reproducing device (1) controls reproduction most suitably as copyright holder' s intention.

(FR)
Selon l'invention, afin d'empêcher l'enregistrement ou la reproduction illégale de données de contenu, des informations permettant de détecter une distribution ou un enregistrement illégal de données de contenu sont ajoutées à des informations en filigrane ou à d'autres informations. On prépare deux ensembles de données en filigrane (WM), un ensemble de données WM1 et un ensemble de données WM2. Dans les données WM1, on intègre des données représentant que les données de contenu sont des données de progiciels médias ou des données de distribution, des informations SCMS, des données représentant que les données de contenu sont enregistrées sur un disque ou sur une mémoire à semiconducteurs, et des données représentant le type de disque ou de mémoire à semiconducteurs. Dans les données WM2, on intègre l'heure de distribution ou l'année et la date sous la forme d'informations temporelles représentant l'heure d'enregistrement des données de contenu. En fonction des données WM1 ou WM2, un dispositif de reproduction de données (1) gère la reproduction de la manière la plus conforme aux intentions d'un détenteur de droit d'auteur.
