CoreHDCPHDMIRX

The CoreHDCPHDMIRX is a specialized IP core designed to comply with the High-bandwidth Digital Content Protection (HDCP) 2.3 specification for secure audiovisual content reception over HDMI. Operating as part of an HDMI Sink system, it is responsible for detecting encrypted frames and decrypting both active video and auxiliary (AUX) data packets using the AES-CTR algorithm. While the core handles secure content processing and link integrity synchronization, the initial Authentication and Key Exchange (AKE) process is performed externally.
