Abstract

Current digital rights management systems employ proprietary methods to protect contents. Hence, they are incapable of interoperation with each other. This causes great inconvenience for users who want to subscribe to contents from different providers. We introduce a new, intellectual property management & protection method (IPMP extension), which enables users to enjoy content services delivered from different providers which are based on individual content protection mechanisms. The method is proposed to ISO/IEC JTC1/SC29/WG11 (MPEG) and the standardization is in the final stage. IPMP is also proposed to DVB-CPT (digital video broadcasting-copy protection technologies). TV Anytime Forum ISMA (Internet Streaming Media Alliance) have adopted IPMP in the ISMA1.0 Encryption & Authentication specification.
