A new open standard for high dynamic range video, called HDR10+, has been announced by Samsung and Amazon. It is described as an update to the already existing HDR10 standard. It includes Dynamic Tone Mapping, which will allow the metadata included in a video to be dynamically based on individual scenes.
This will allow the brightness levels to vary, depending on the particular scene, adjusting to a bright or dark image. HDR10 performed this with static data, which means that if the greater part of a video is dark, then the brighter portions will previously be oversaturated relative to the rest of the video clip.
The addition of dynamic metadata helps move the open HDR10 standard closer to the closed Dolby Vision Spec standard, the latter had differentiated between the two stating that dynamic metadata as one of its key elements.
HDR10+ Won’t Require New Hardware
However, the introduction of the HDR10+ standard does increase the number of standards the industry will now have to support, alongside the previous four standards: HDR10, Dolby Vision, HLG, and Advanced HDR. Interestingly enough, HDR10+ will not require people to buy new hardware.
The new standard is already supported by Samsung’s 2017 UHD TV sets. It will also be released for the company’s 2016’s lineup through an update that will release later in 2017. This, theoretically, means that other companies interested in adding support for the new standard will be easily able to do so.
The only major content company signed up to support the new standard is Amazon Video. It will provide HDR10+ supported service later in 2017. This goes to show that the evolution of HDR standards will likely be to slide along differing qualities of the same base stuff. Unlike the format clashes of the past, such as Blu-Ray vs. HD DVD, HDR won’t have to trouble consumers with difficult hardware changing decisions.
