Another lounge room format war is looming as Samsung and Amazon Video unveil HDR10+ to rival Dolby Vision, backed by LG and Netflix. Here are the ugly details.
High Dynamic Range has been the Next Big Thing in home entertainment for the last few years, boosting the contrast to reveal more detail in the brightest highlights and darkest shadows. I'd argue that it's more important than 4K, as HDR dramatically improves the picture quality regardless of the screen size and resolution.
While HDR goes by a few names, until now the various formats have been backwards compatible so you wouldn't class it as a true format war. You haven't really been forced to choose between them, but that's about to change.
Heart of Darkness
HDR10 is the baseline HDR format, with metadata which sets the dynamic range – the difference between the brightest white and the darkest black – for the entire movie. Meanwhile Dolby Vision includes extra metadata which allows the television to adjust the dynamic range for each scene, plus Dolby Vision supports a wider 12-bit colour range and maximum 10,000 nits brightness. Put to the test you can clearly see the difference.
Dolby and LG cheekily describe HDR10 as "generic HDR" to goad their rivals, but the good thing is that Dolby Vision-compatible gear can still play HDR10 content – you still see the benefit of HDR, you just lose the extra detail which Dolby Vision brings to the picture. Likewise HDR10-compatible gear can still play Dolby Vision content, but it only looks as good as HDR10.
These days you'll find HDR10 on most Ultra HD Blu-ray discs and some streaming services, but we're still waiting for the first Dolby Vision-compatible Ultra HD Blu-ray discs and players – which should be on the shelves by the end of the year. Until then Netflix is Australia's only source of Dolby Vision content.
Dolby Vision is a closed standard, players and televisions require a built-in decoding chip and manufacturers must pay licensing fees to Dolby. LG has championed Dolby Vision and a few other major television makers are onboard, but fellow Korean tech giant and arch rival Samsung is not one of them.
There is another
Rather than jumping on the Dolby Vision bandwagon, Samsung has teamed up with Netflix rival Amazon Video to create the open HDR10+ standard. Building on the HDR10 baseline, HDR10+ adopts Dolby Vision's ability to optimise the dynamic range on the fly by embedding extra metadata for each scene. The new HDR10+ format still falls short of Dolby Vision when it comes to colour range and maximum brightness.
Presumably HDR10+ is backwards compatible with HDR10. The good news is that HDR10+ doesn't rely on a special decoding chip, it's already supported on all of Samsung's 2017 Ultra HD televisions and is coming to last year's models via a firmware update. It's an open standard, so other television makers are welcome to get onboard.
Meanwhile Amazon Video is committed to start streaming in HDR10+ across the world this year, although there's no word as to whether HDR10+ is coming to Ultra HD Blu-ray discs.
So where does that leave us? It's unlikely television makers in the Dolby Vision camp like LG will add HDR10+ support, while it's pretty certain those in the HDR10+ camp like Samsung won't embrace Dolby Vision. Until now Dolby Vision was your safest option, but now you risk missing out on the improved picture quality when watching HDR10+ content, and vice versa. Each format will downgrade rival content to standard HDR10.
The good news is that Amazon Video already supports Dolby Vision, so with the addition of HDR10+ it will cover all the bases – although it remains to be seen which Amazon content features which HDR format. It also remains to be seen whether Netflix, one of Dolby Vision's key partners, will embrace HDR10+.
Only time will tell whether one format turns out to be a dud, the HD DVD or Betamax of High Dynamic Range. Anyone burned by the format wars of the past is advised to watch this space carefully.
Netflix has declared 2017 the year of High Dynamic Range (HDR) programming. The popular streaming service has already dramatically expanded its 4K HDR content - and there's a lot more to come in the months ahead. Last year, we were invited to check out the company's state-of-the-art colour correction suite in New York where Netflix Originals receive a fresh lick of digital paint in the HDR conversion process. Here's everything we learned.
Dear Lifehacker, I've been hearing a lot about HDR TVs and how "revolutionary" they are. One so-called expert called it the biggest technological leap since the first colour TV. The thing is, similar things were said about 3D TV and look how that turned out! So my question is, does HDR really matter or is it just another marketing gimmick?
