Software-hardware Co-design And Research Of Hdcp For High-definition Multimedia Digital Signal

With the rise of digital-TV brings multimedia entertainment enters the high-definition times. It supports 1080p (1920×1080). Digital TV content providers ask government to protect their copyright. So the protection of high-definition digital content becomes more and more important. Against this background HDCP (High-bandwidth Digital Content Protection) is developed.This paper studied HDMI interface and HDCP protocol. We then completed software-hardware co-design of the SHA-1 module, modeled the implenmented architecture on ARM ESL design platform, and also evaluated the system performance promotion after improving the algorithm. In chapter four, HDCP transmitter architecture is introduced. Design of Cipher and according software had been introduced. To wrap up the thesis, comparisons between simulation diagram and protocol logic were showed, to prove the correctness of the design.
