High-Definition Multimedia Interface (HDMI), released late in 2002, is an all-digital audio/video interface capable of transmitting uncompressed streams of data. Based on the Digital Visual Interface (DVI) definition. Therefore HDMI is very similar to DVI in many ways but at the same time different in two big ways. One is that HDMI carries audio as well as video where DVI does not. The other is that HDMI also incorporates HDCP, which is a Digital Rights Management technology. The HDCP technology limits the ability to convert HDMI to other connection formats without degrading the signal. This is actually by design. For additional details on HDMI, see our articles below.
