(English Abstract)
In this paper, we proposed the digital contents distribution business model for the operation of integration between heterogeneous systems in order to use IPTV. Also, we designed and implemented the protection management system through this distribution business model. This proposed model maintains interoperability between the heterogeneous systems, creates rights protection document based on REL, and provides the new version of packaged digital contents to itself by packaging the digital contents. Overall, it ultimately offers an interoperable environment. Moreover, since we pre-defines the relations among REL data based on MPEG-21 standard, which creates the newly packaged digital contents, it is easy to edit data. We can expect to save expenses of digital contents distribution and rights protection technology. Additionally, we can further improve security by encapsulating the security technology of CAS and DRM system.
