Over the past couple of decades, the Moving Picture Experts Group (MPEG) have set the standards when it comes to video and audio compression. The newest form, MPEG-21, will change the way people share media. To give a brief overview, MPEG-21 is a Rights Expression Language (i.e., Digital Rights Management), and its framework rests on the delivery and consumption of media.
Its goals are to:
- define a machine-interpretable language's syntax and semantics to specify rights unambiguously
- provide an authorization models to determine if a principal has the right to act on a resource according to REL expressions; and
- support many business models in the end-to-end distribution value chain. (Smith and Wang)
This will change the way people share media since computer code will determine who has the right to access certain media. Since the structure of MPEG-21 includes event reporting, companies will be able to keep a record of how users manipulate, trade, or simply consume media.
