Design Considerations

The Digital Visual Interface (DVI) Specification, is an industry standard devel- oped by the Digital Display Working Group (DDWG) for high-speed digital connection to digital displays. DVI uses Transition-minimized DC balanced (TMDS) data signaling. Single link supports up to 165Mpixels/s – UXGA FPDs, SXGA DCRTs, 720p and 1080i HDTVs.

High Bandwidth Digital Content Protection (HDCP)

•Content protection for video sent over DVI

•Implementation of HDCP requires a license from the Digital Content Protection Licensing, L.L.C. (www.digital-cp.com)

HDCP Elements

•Authentication is a process for verifying that a device is authorized (e.g. licensed) to handle protected content.

•Encryption prevents eavesdropping of protected content.

•Renewability enables revocation of compromised devices.
