摘　　要：分析了数字版权管理(DRM)系统产生的原因、研究现状,以及DRM系统的基本结构。针对现有DRM系统之间的协作问题,文中分析了格式互用、连通互用、配置驱动互用三种解决方法及其优缺点并提出使用原则。最后,提出了实现连通协作方法的框架,并以多媒体分发应用为例,用实验验证此框架支持DRM系统间协作的特性。The origin, research status and basic architecture of Digital Rights Management (DRM) were presented. Aiming at current DRM systems interoperability, Full Format Interoperability, Connected Interoperability and Configuration-driven Interoperability approaches were put forward. Their Pros and Cons were analyzed and application principles were outlined. In the end, an architecture supporting Connected Interoperability was suggested, and a multimedia-distribution-application example resulting from experiments was given to illustrate the interoperability of DRM systems based on the architecture.
