HDMI 2.0 Design And Verification Challenges

HDMI designs face challenges with respect to run time and memory consumption due to the huge size of HDMI frames. Scrambling adds more complexity and designs face synchronization and timing challenges. Similar challenges are faced during the functional verification of systems-on- chip (SoCs) including HDMI interfaces. These challenges can be addressed using HDMI verification IP (VIP).

High-Definition Multimedia Interface (HDMI) is an audio/video (A/V) trans- mission 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.
