What They Say
HDR10+ Technologies LLC said that Google and Roku have now certified HDR10+ products. Roku said
“We recently announced Roku OS 10, a free software update rolling out to Roku devices, and we have enabled HDR10+ on the all-new Roku Express 4K+, Roku Express 4K and Roku Ultra (2020) products…”
The group also referred to new APEX (Airline Passenger EXperience) Association standard which allows HDR10+ content to be enjoyed during in-flight entertainment.
It also made a whitepaper on HDR10+ available for download.
What We Think
The white paper is a reasonably summary of HDR10, HDR10+ and HDR10+ Adaptive, without, of course, mentioning alternatives such as Dolby Vision.
I hadn’t previously spotted the APEX specification. Its number is APEX 0415 and version 3 was modified to support HDR including HDR10+ and Dolby Vision. I found this talk by Juraj Siska that included some background on the challenges in introducing HDR (and his talk is transcribed here. I must say that most aviation displays that I have seen in planes can’t even do SDR very well! The aviation industry has a 250 cd/m² specification for SDR and 500 cd/m² for HDR, with a need for a ‘night mode’ for dark environments. It looks as though the Apex specification is only available to members. The chair of the working group on APEX 0415 is from Panasonic, which is no surprise as the firm is strong in the In Flight Entertainment (IFE) market. (BR)
