Samsung and Amazon announce HDR10+ with dynamic metadata

21 April 2017 2

Samsung and Amazon have teamed up to announce a new high dynamic range video open standard named HDR10+. It is an upgrade over the previous HDR10 and brings "dynamic metadata" as the major change between the two standards. It also closes the gap between HDR10 and Dolby's Dolby Vision HDR standard.

With the addition of dynamic metadata in HDR10+, it will now be able to adjust the brightness of the display depending on the particular scene or even frame-by-frame. This will allow users to watch each scene as the director of the video intended and should be able to deliver better video quality for HDR videos.


Prior to this, Samsung's HDR10 standard used to work with fixed metadata. It means it used a static metadata for adjusting video brightness which would result in not so good video quality for specific scenes. For example, if a video has most of its scenes in bright light and a few of them slightly on the dark side, those few scenes would appear darker than they were intended to be because of the static metadata information.

All of Samsung's 2017 UHD TVs as well as the premium QLED TV family supports the HDR10+. It will also be updating 2016 UHD TVs to make them compatible with the new standard. And as Amazon is the partner, Prime Video will be the first one to offer video content with HDR10+ support globally which is said to happen "later this year".

With this new standard, Samsung has surely reduced the gap with Dolby but the latter is still quite ahead of its standard with features like the maximum 10,000 nit brightness and 12-bit color range. One of the major difference between these two HDR video standards is that Samsung's offering is an open standard and Dolby's offering is closed. It means anyone is free to use HDR10+ without paying any fee but for using Dolby Vision HDR, TV makers and content creators have to pay royalty fees.
