Overview
ISO/IEC 21000-4:2006/Amd 2:2012 is an amendment to the international standard ISO/IEC 21000-4, which is part of the MPEG-21 multimedia framework. This amendment specifically addresses the protection of the presentation element within the Intellectual Property Management and Protection (IPMP) components of MPEG-21. The standard is developed by the joint technical committee ISO/IEC JTC 1, Subcommittee SC 29, which focuses on coding of audio, picture, multimedia, and hypermedia information.
The MPEG-21 framework aims to enable transparent and augmented multimedia delivery across a variety of devices and platforms. Part 4 focuses on mechanisms for managing and protecting intellectual property rights in multimedia content. Amendment 2 enhances this by defining a new element for governing protections related to presentation aspects of multimedia content.
