ABSTRACT
Digital media can be exploited by intellectual property (IP) owners to develop new and innovative business models for their products and services. The lowered cost of reproduction, storage, and distribution, however, also invites much motivation for large-scale commercial infringement. This chapter presents an overview of copyright and copyright industries and examine how the technological, legal, and business solutions help maintain the incentive to supply the lifeblood of the markets. Protection of digital multimedia content therefore appears to be a crucial problem for which immediate solutions are needed. There are three industries with vested interest in the digital content protection arena: motion picture, consumer electronics, and information technology. Digital Rights Management (DRM) refers to the protection, distribution, modification and enforcement of the rights associated with the use of digital content. Renewability is achieved by upgrading DRM system components and preventing the compromised devices from receiving content.
