Abstract:

This paper focuses on the study and design of the receiver of High-bandwidth Digital Content Protection(HDCP).It also analyzes the basic structure of HDCP receiver and discusses the design method,including the design for four sub-modules,Cipher datapath,controller,register and I²C interface.HDCP is an IP core embedded in Digital Video Interface(DVI) or High Definition Multimedia Interface(HDMI) chips.The integration of the HDCP in DVI＼HDMI chips can ensure the legality and confidentiality of video data in its transfer between two devices.
