    • A conventional copy control using an electronic watermark has a problem that an additional process is required depending on the control specification, thereby deteriorating the efficiency if the control specification differs between the applications and the same process is performed. A recording device for performing copy control by using the copy control information indicating a plurality of copy control methods includes electronic watermark detection means (103) for detecting copy control information of a predetermined part of the copy control information from a content superimposed by an electronic watermark indicating the copy control information and recording means (104) for recording a content according to the detection result of the electronic watermark detection means.
    • 使用电子水印的常规复制控制存在根据控制规范需要附加处理的问题,从而如果控制规范在应用之间不同而执行相同的处理,则效率降低。 用于通过使用表示多个复制控制方法的复制控制信息进行复制控制的记录装置包括电子水印检测装置(103),用于从由电子水印叠加的内容中检测复制控制信息的预定部分的复制控制信息 指示用于根据电子水印检测装置的检测结果记录内容的复制控制信息和记录装置(104)。
