Application and implementation of UCPS based on HDMI interface

UCPS (UCPS, Unified Content Protection System) specification has been used in HDMI(High-Definition Multimedia Interface) interface in terms of software and hardware. Based on UCPS technical specification, the paper deep analyses how the technical specification can been used in HDMI Interface. We design the hardware circuit and the authentication drivers, based on HDMI chips (sil9013 and sil9024), and also do experiment to prove that authentication drivers are right and HDMI interface has the ability to authentication.
