The CPSA Ecosystem

4C Entity has developed a comprehensive, standards-based framework for unifying various content protection technologies, including CPRM and CPPM. The Content Protection System Architecture (CPSA) was developed to integrate major existing content protection technologies from the personal computing and consumer electronics industries, as well as new technologies as they emerge in the years ahead.

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.
