Dolby has worked closely with industry leaders over the last 50 years to make the stories and experiences as engaging as possible—first with noise reduction, then 5.1 surround and 7.1 surround, and now with Dolby Vision™. Dolby Vision™ transforms the way you experience movies, TV shows, and games with incredible brightness, contrast, and color that bring entertainment to life before your eyes. By fully leveraging the maximum potential of new cinema projection technology and new TVs’ display capabilities, Dolby Vision™ delivers high-dynamic-range (HDR) and wide-color-gamut content. The result is a refined, lifelike image that will make you forget you are looking at a screen.
4K televisions have “more pixels” and newer standards for UHD TV also include high frame rates, but these standards don’t make each pixel able to better represent the full range of brightness we see in reality. Dolby Vision™ is the Dolby Laboratories solution to meet this challenge. The current TV and Blu-ray standards limit maximum brightness to 100 nits and minimum brightness to 0.117 nits, while also limiting the range of colours that can be displayed. Dolby Vision™ colour depth allows up to 10,000-nit maximum brightness. (Dolby 2016)
In the compatibility test for Dolby Vision™ Unigraf will provide playback and capturing of the test video and audio content with UCD-series test tools. Dolby will provide customers with the SDK (Software Development Kit) that enables analyzing the Dolby Vision™ video captured with UCD-series test tools. UCD-series test tools also support Dolby Vision signaling test using Dolby Vision VSIF and Dolby Vision Vendor Specific Extended Metadata Packets (EMP) using TMDS. With the Dolby SW package, UCD-series test tools are a mandatory tool for any e.g. television or monitor manufacturer that is willing to have a Dolby Vision™ certificate on their products.

Unigraf’s solution integrates Klein K-10A colorimeter for automated testing of HDR 10+ Display Device tests allowing users to set and play the patterns without having to manually measure luminance values of HDR 10+ patterns. Users that do not have Klein K-10A colorimeter will be able to manually record measured luminance values into the software GUI. This solution is easy to use and reduces the time required to run HDR 10 Display Device certification tests.
