DVI refers to a type of Digital Video connection. This method is a high quality connection for HDTV's and Set Top Boxes/Receivers that support it.

Video is compatible with HDMI provided both devices are HDCP compatible. DVI carries uncompressed video data, but no audio. Point to point interface - connects only two devices at a time.

This type of connection is used on some HDTV's, Projectors, Set Top Boxes and Receivers. DVI cables are usually only available in limited length. DVI will be replaced by HDMI for Home Theater applications.
