However, there is no specification on how to enforce the usage rights of digital content in the DVB standards. As a result, even if the digital content is protected under the conditional access sub-system, end users can still copy and redistribute the digital content once it is descrambled. In this paper, we proposed a DRM system for set-top box which supports Multimedia Home Platform middleware. The rights of the protected digital content are described using the MPEG-21 Rights Expression Language and broadcasted with the digital content. In the proposed system, the rights are stored in the smart card. The proposed system is highly renewable and extensible. The service providers can integrate this system with their existing broadcast services without additional hardware cost. ©2006 IEEE. |
