MPEG IPMP concepts and implementation

Abstract

Intellectual Property (IP) protection is a critical element in a multimedia transmission system. Therefore, ISO/IEC MPEG started the IP protection standardization project on MPEG-4 a few years ago. A basic IPMP (Intellectual Property Protection and Management) structure and interface was first defined in its System part. In this paper, we will first outline the MPEG-4 basic IP protection mechanism and then describe our simulation of an MPEG-4 IPMP system. An IP protection application is constructed using the MPEG-4 system software - IM1 (Implementation Model one). This application includes a client-server program, in which a client can request the keys from a server in a secure way using a hierarchical key distribution structure.
