Display Interfacing 2017: Getting Around the UHD ‘Speed Bump’

The growth of UHD imaging and the addition of high dynamic range (HDR), wide color gamut (WCG), and high frame rates (HFR) are pushing display interfaces to ever-higher clock and data rates. However, current interfacing standards are too slow to accommodate many of these rates. We're pushing the limits of copper wire interfaces and are now compressing display signals for the first time. The newest version of HDMI (2.1) won't be widely available for a few years and may require optical fiber connections at higher speeds. In the meantime, DisplayPort (1.4) is ramping up its bus speeds to new highs and adopting support for consumer video formats. This presentation will provide updates on the latest interface architectures and speed challenges, and will also consider network signal transmission as an alternative connection method.
