HDMI is a consumer products video interface specification as set by the HDMI organization (www.hdmi.org). The organization was founded by consumer products companies to both simplify the inter-connection of consumer media devices as well as protecting the interests of content developers (by using encryption, HDCP, and other restrictions).
From 1 January 2012 HDMI was no longer referred to with version numbers, instead the reference will be HDMI Standard, HDMI Standard with Ethernet and so on.
Due to the growing popularity of HDMI many non-consumer products have also incorporated HDMI support – as a note one of the most frequently mentioned drawbacks in this context is the lack of any locking mechanism in the connector design.
The digital alternatives: 3G-SDI/HD-SDI, DVI, DisplayPort, HD-BaseT.
