DRM (digital rights management) interoperability has been the barriers for seamless content consuming. Consumers suffer from being incapable of enjoying content through several devices because most of the DRMs don't provide consuming the other DRM content. Some technologies and standards are appeared or in progress. But most of them result in another DRM -they don't support the previous DRMs, but they are only new DRMs. In this paper, we propose the persistent content protection scheme and show implemented prototype system which is able to support the existing DRMs.
