著作权保护数据处理系统以及再现装置

Copyright protection data processing system and reproduction device

Abstract

When a reproduction device is disabled to reproduce R media, there arises a problem that it takes a long time to manufacture commercial ROM media. On the contrary, when the reproduction device is allowed to reproduce the R media, there arises a problem that the copyright may be infringed. It is judged whether reproduction is to be enabled or disabled according to the type of a recording medium and the type of a signature attached to the program, so as to make a decision. With this configuration, it is possible to effectively manufacture commercial ROM media while protecting the copyright of a content.
在对于再现装置禁止了R介质的再现时,存在商用ROM介质的制作花费时间的问题,相反地,在对再现装置许可R介质的再现时,存在著作权可能被侵害的问题。本发明具有根据记录介质的类别、程序被赋予的签名的类别来判定并决定可否再现的结构。根据该结构,能够保护内容的著作权,并且有效地进行商用ROM介质的制作。
