Digital Rights Management (DRM) is a concept for controlling the distribution and consumption of digital media. As embedded multimedia devices are becoming popular, there are strong demands for the light-weight DRM systems that can run smoothly in a resource-limited environment. Due to the variety of embedded devices, an ideal DRM system should be platform independent and interoperable. These requirements, however, often increase the software complexity, which is undesirable to an embedded device. In this paper, a switchable DRM system is thus proposed. It integrates the concept of downloadable tools and the OMA architecture to provide a balance between flexibility and complexity. We also implement the scheme on an embedded evaluation board to demonstrate its feasibility.
