Abstract: This paper introduces the development in DRM and home network DRM. Through the comparison between them, it proves the integration of both kinds of systems is necessary. It proposes a novel solution for the integration. The solution can not only make content and certificates sharable at home but also protect the benefits of content providers and provide the ability to control and trace. It discusses the feasibility of the solution and the results prove it.
