When HDMI 2.0 was introduced with much Fanfare in September of 2013 (wow time flies!) there was a lot of misunderstanding and misinformation. This brings us to HDMI 2.0 and the new 18 Gbps standard. This revision had the first actual cable performance change (from 5 to 10 Gbps) since the introduction of HDMI and is where we still are almost 10 years later! The HDMI 1.4 spec introduced in 2009 added features to the electronics but did not have any cable changes except for the “not yet used” Ethernet support. In 2006 the HDMI 1.3 spec was released, this covered several new features and an expanded bandwidth of 10.2 Gbps. The original HDMI Spec 1.0, 1.1 and 1.2 (2002-2006) allowed for 5 Gbps of data transfer, this supported 1080P, 8 Bit color, Multi-channel Audio and EDID/HDCP. ![]() To fix this shortcoming, Silicon Image (creator of DVI) took the functioning structure of DVI and the HDCP protection scheme developed by Intel and put it all together into a smallish terminal that carried the High Speed Video, Multi-Channel Audio, Intelligence and Security together as one. They would not release “HD” content to without a strict level of “Intellectual Property” protection. They felt motivated by and ultimately compelled to limit market availability due to what they assumed were their intellectual property rights. Not long after DVI was introduced, the movie and TV industries started looking for ways to secure their new “HD” content. Some of the issues were the lack of a single Plug/Wire standard the inability for the signal path to travel more than 15’ consistently no audio standard and a very large terminal. ![]() DVI performed as intended - but not without problems creating a roadblock to future implementation. In the beginning, there was DVI created by silicon image which was intended to be a computer video interface that provided a true Digital High Speed Video connection over a relatively short distance. Let’s look at how we evolved, where we are presently, and where we are headed in the future: To fully understand the new technology, let’s review. The question is: “As an industry, how do we salve the fears and provide the client with what they need to move forward with the new HDMI interface?” Be sure to watch for Part 2, Into the Future of HDMI in our next installment. We’ll examine some of the issues we’ve had to deal with as we get underway with this new frontier in Part 1. ![]() Dealers and manufactures are afraid of HDMI while customer demand is looming. Although HDMI® 2.0 has been out for a while, this technology still has a dark shroud of mystery surrounding it.
