If you thought that the two different HDR (High Dynamic Range) – Dolby Vision and HDR10 – were confusing enough, allow Samsung and Amazon to confuse you even further. The two companies have launched their very own HDR10+ standard. It’s an updated version of the HDR10 standard and comes with a new feature called Dynamic Tone Mapping. The feature users dynamic metadata to produce improved contrast and colors on a wide range of televisions.
The existing HDR10 standard relies on static metadata which doesn’t change during playback even though different scenes have different brightness levels. This results in image quality not being optimal in some scenes. HDR10+ relies on dynamic metadata which enables an HDR-compatible TV to adjust brightness levels on a scene-by-scene or even a frame-by-frame basis.
All of Samsung’s 2017 UHD TVs including its QLED lineup have support for HDR10+. Samsung’s 2016 UHD TV lineup will also get HDR10+ support in the second half of this year. Those who want to experience the enhanced HDR experience will find compatible content on the Amazon Video streaming service.
This also makes Amazon Video the first streaming service provider that developed its own HDR standard for audiences. HDR10+ support is integrated with the x265 High Efficiency Video Coding (HEVC) which is available for free under an open source license.
