4C ENTITY MAKES IT EASIER TO SHARE PROTECTED DIGITAL CONTENT

Today’s consumers want to enjoy high quality entertainment such as music, movies and streaming video wherever and whenever they wish. That means being able to easily shift copyright-protected content among a fast-growing array of digital devices – from multimedia PCs and DVRs to personal music players, mobile phones and in-vehicle systems.

The 4C Entity was formed to develop technologies that will enable premium content to be shared as authorized on a wide range of electronic devices built by multiple manufacturers. 4C Entity is working to provide consumers with flexible access to all forms of digital content, while ensuring that the content is high quality, easy to store and maintain, transferable to similar digital devices and copyright-holder friendly.

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.
