- This paper proposes a scalable video coding (SVC) DRM mechanism considering the convergence environment that redistributes the adaptive content for devices which may have different display size and computing capabilities between users or in the home network. The proposed SVC DRM mechanism uses the SVC content that is compressed by H.264/SVC scheme which has been standardized recently and encrypted by SVC encryption scheme so that each device gets a content of suitable level according to its own device capability. For the secure and efficient superdistribution of SVC content, moreover, this paper defines four requirements for SVC DRM and proposes a mechanism which satisfies these requirements by using another license called ?쁔icket??. In addition, our system allows devices to redistribute the contents freely in the home network since the devices in the domain are managed by the domain key.
