| Summary: | 碩士 === 國立交通大學 === 電機資訊學院碩士在職專班 === 92 === Many existing DRM (Digital Right Management) systems in the market may no longer sustain, due to the rapidly growing computer technology. 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.
