What does MPEG-4 IPMP manage and protect?
An IPMP system manages the level of access to protected digital material that may made available through an MPEG-4 application. This may be to protect to value of the digital material. However, it may that the material has no intrinsic value but it must still be protected to preserve various rights of privacy. Where it is required, MPEG-4 IPMP can be used by IPR owners to protect information about the creations which they own within an IP Identification Data Set (please refer to Documents WG11/N1918 and WG11/2614 for further information) stored within the scene descriptors associated with each digital object. This information is a critical tool for IPR owners to interface with Electronic Copyright Management Systems to facilitate automated transactions such as the monitoring and tracking of usage.
