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.

(ZH)

为了防止内容数据被非法记录或者再现,对水印信息或者其他信息附加用于检测非法配信或者记录该内容数据的信息。准备了两个WM(水印)数据集,即,WM1数据集和WM2数据集。关于WM1数据,设置表示该内容数据是封装介质数据或者配信数据的数据、SCMS信息、表示该内容数据记录在盘或者半导体存储器内的数据以及表示盘或者半导体存储器的类型的数据。关于WM2数据,设置配信时间或者年和日期,作为表示记录内容数据的时间的时间信息。根据WM1数据或者WM2数据,数据再现设备(1)对再现进行控制使之最适合版权持有人的意图。
