HDMI 2.0 Design And Verification Challenges

A look at the new audio/video standard, how it applies to 4K ultra-HD, and what you need to know about it.


High-Definition Multimedia Interface (HDMI) is an audio/video (A/V) transmission protocol, which is omnipresent in consumer electronics, personal computing, and mobile products. Modern-day requirements of big screen resolutions, 3D, and multi-channel/multi-stream audio have pushed display devices to use a completely digital, high-speed transmission media, requiring a multi-layered protocol like HDMI.

HDMI 2.0 is the next generation of the popular audio/video high-definition standard and it is the successor to the current HDMI 1.4a/b specifications. The oncoming rise of 4K Ultra HD is the reason behind the entry of HDMI 2.0 into the market. Since 4K Ultra HD is four times the resolution of 1080p, the current HD standard, there is a need for more throughput to handle large amounts of data. Some of the key features of the HDMI 2.0 specification include scrambling, character error detection, and dynamic auto lip-sync.
