The best example of the differences between SDR and HDR patterns is the PLUGE or Black level test pattern. These are some of the aspects of HDR that required the design of HDR specific test patterns. Add to that the fact that HDR10 content can be mastered with a peak luminance reference of 1000 or 4000 Nits depending on what the studio wants to do, it further complicates things in terms of evaluation and optimization. Another factor is that we now have on the market displays from Samsung, Sony and others that are capable of well over 1000 Nits (cdm2) of peak light output, which is considerably brighter than any consumer displays we’ve ever had for SDR playback. The main reasons are the vastly different levels (black, white), and the new EOTF PQ or SMPTE 2084 gamma curve in HDR versus SDR. The disc has now been distributed to key members of the industry’s technical press, and prominent ISF Calibrators around the country.įriedrich, who is a pioneer in the area of understanding and utilizing HDR video, determined early in his experimentations that SDR test material did not work to effectively evaluate the performance of HDR displays.

In late June of this year, we introduced the Reference UHD HDR test disc at the CE Week show in New York City, and conducted demonstrations on its design, intent, and usage. The Reference UHD HDR test disc is the first effective tool for evaluating and optimizing HDR displays. The company then commissioned Florian Friedrich, CEO of AV-TOP in Munich, Germany to produce the disc. Just over a year ago, I was approached by Samsung with the idea of a UHD Blu-ray test disc, and was asked to draft an outline. SAMSUNG RELEASES HDR10 REFERENCE UHD BLU-RAY TEST DISC
