HDR10+ Finally Arrives, In Over 100 titles From Amazon Prime For Samsung 4K TVs
Juan Carlos Ropel – December 16, 2017
Starting this week after an announcement by Samsung, Amazon Prime Video now streams its entire Prime Video HDR library in HDR10+ format, which includes over a hundred titles of series and movies. The HDR10+ format will be compatible with all of Samsung’s 2017 UHD TV lineup, including its premium QLED TV models.
HDR10+ was developed by Samsung in collaboration with Amazon and other major companies as a new alternative to the Dolby Vision high dynamic range format which has always been considered superior to the previous HDR10 high dynamic range format, and thus offers an improved version of the current HDR10 open standard. The HDR10 standard itself utilizes static metadata that does not change during playback despite scene specific brightness levels. HDR10+ enhances this by adding Dynamic Tone Mapping, which applies and individualizes tone mapping for each scene, delivering an incredible viewing experience by adjusting brightness levels on a scene-by-scene, and even a frame-by-frame-basis.
HDR10+ still isn’t quite as good as Dolby Vision though. While HDR10+ and Dolby Vision both use dynamic metadata that carries frame-by-frame instructions for HDR mastering, HDR10+ is still stuck with a 10-bit color depth while Dolby offers a 12-bit palette and support for a maximum 10,000 nit brightness, far exceeding what HDR10+ or its predecessor are designed to support.
On the other hand, Dolby Vision charges royalties for using its tech, whereas Samsung’s HDR10 and HDR10+ are open standards, meaning that they can be adopted by other TV companies for free. This reduces the cost of manufacturing HDR televisions and has encouraged other huge companies like 20th Century Fox and Panasonic to adopt HDR10+ for the sake of forming a sort of HDR10+ alliance to promote the format and establish a certification program. Netflix has also commented the possibility of supporting HDR10+ in the near future.
The Amazon Prime Video HDR10+ catalogue includes hundreds of hours of content such as Prime Originals The Grand Tour, The Marvelous Mrs. Maisel, Jean-Claude Van Johnson, The Tick and The Man in the High Castle plus hundreds of licensed titles.
