4C Entity has developed a solution: Content
Protection for Recordable Media (CPRM) and Content
Protection for Pre-recorded Media (CPPM). The CPRM/CPPM
specification defines a renewable cryptographic method for protecting
entertainment content when recorded on removable and portable physical
media including, but not limited to, DVD media and Flash memory.
The CPRM/CPPM specification was designed to meet the robustness and
renewability requirements of content owners while balancing the implementation
needs of both the consumer electronics and PC industries. Multimedia
applications enabled by 4C technologies are creating vast new market
opportunities for content providers, service providers, application
developers and device manufacturers. By using 4C Entity technology solutions and specifications, device
manufacturers can offer consumers a wide range of choice for sharing
premium content among digital devices while reducing long development times and resources.
