CPSA (Content Protection Security Architecture) provides a comprehensive framework for integrating existing and new content protection technologies. It defines key technologies like watermarking and encryption. Watermarking embeds usage rules in content without the user's knowledge, while encryption requires a license to decrypt content. CPSA compliance ensures technologies work together, including formats like CPRM for recordable media, CSS for DVD video, and DTCP for digital transmission.
