Difference between DVI and HDMI
Even though DVI HDMI are discussed keeping side by side, there, in reality, exists lots of differences between the two. Are DVI and HDMI well-matched? Which one is better of the two? There are, in fact, lots of questions that may flummox an ordinary individual. Let’s have a brief study to found out the reality.
Digital Visual Interface (DVI) happens to be the digital standard introduced in 1999 at the behest of Digital Display Working Group (DDWG), is designed mainly for carrying uncompressed digital video data to a display. In the beginning the display was a computer monitor but DVI is now normally used for television too.
High-Definition Multimedia Interface (HDMI), on the other hand, released late in 2002, happens to be an all-digital audio/video interface capable of transmitting uncompressed streams of data similar to DVI. But HDMI also provides the ability to carry audio signals, as well as video, incorporating HDCP, which is a Digital Rights Management technology.
Lots of studies point out presence of commonality between the two than differences. Is it so? Well, these studies have been erroneous. There are, in point of fact, two big differences. While
HDMI incorporates content protection called High Definition Content Protection (HDCP),
HDMI is found to support audio in addition to digital video. (DVI supports digital video only).
Which one should be used then? Well, if available, HDMI is always recommended. This is not much better than DVI but industry’s reliance on HDCP Digital Rights Management technology makes all differences.
