摘要:

研究了高带宽数字内容保护技术的接收端设计。分析讨论了HDCP接收端的基本结构以及实现接收端的设计方法,其中包括数据加密、控制器、寄存器、I2C接口共4个子模块的设计。HDCP是一个内嵌在数字电视接口或高清晰度多媒体接口芯片中的IP核模块。将HDCP集成在DVI\HDMI接口芯片中,可以保证视频数据在视频设备间传输的合法性、保密性且不被窃取。

关键词: HDCP, 接收端, 高带宽

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.

Key words: HDCP;receiver;high bandwidth
