This is one of the serious problems encountered in digital content delivery business. It is therefore desirable to establish a robust flexible DRM system. So, MPEG group defines Intellectual Property Management and Protection (IPMP) in order to solve DRM system problem. IPMP-X is the extension to the old MPEG-4 IPMP hook. IPMP defines one of the processing chain in the DRM system. Its purpose is to define a compliant terminal platform such that for various terminal systems there is a consistency usage environment for the right associated with content. This will allow DRM system and manufacture have a standard to follow and guarantee the interoperability. We study MPEG-4 IPMP-X Specification and investigate MPEG-4 IPMP-X software reference code supported by IM1.We implement two applications about Multimedia Content Guard application based on MPEG-4 IPMP-X: one is Digital TV conditional access application, and the other is DVD copy protection application. We also trace a software reference code supported by IM1.The software reference code is about MPEG-21 Right Expression Language in a MPEG-4 IPMP-X .Future, we will extend to MPEG-21 Right Expression Language and MPEG-21 IPMP based on this foundation. We will extend and implement application of the MPEG-21 Right Expression Language and MPEG-21 IPMP in the future.
