Digital Visual Interface - (DVI) - The DVI interface is an all digital interface allowing uncompressed high-definition content to be passed to another DVI equipped device, such as an HDTV set. High-bandwidth digital content protection (HDCP) will often protect data flowing over a DVI link from a video source to a digital display, such as an HDTV set. DVI attempts to make the content uncopyable. See the Interactive Television Institute.
