Unified rights management for ipmp system

摘要

A method for any IPMP terminals or digital consumption terminal like MPEG-4 system achieves interoperability for handling rights management in different content distribution chains. ;By using a defined and standardised unified rights description language and schema architecture world-wide, by defining the right place or position to hold such standardised rights schema in a content stream, by pre-implementing rights parser and rights management in a terminal based on such rights schema and the specified position for holding the rights descriptions, interoperability can be achieved across content distribution chain, across different countries, across different manufactures for making the terminal, and across different content providers. Such interoperability will bring us low cost for making the terminal, and also low cost to create and distribute a content. ;Flexibility and extensibility are also provided since it is based on flexible and extensible XML-like language.
