When it comes to HDR video on smart TVs today, there are a few different formats, including HLG, Dolby Vision, HDR10, and HDR10 +. But Dolby Vision is by far the most popular.

So when Samsung, whose screens account for 32,9% of the global TV market, which makes it one of the largest producers of televisions in the world, choose to adopt HDR10+ instead of Dolby Vision certainly raises questions.

Samsung said it would not support Dolby Vision due to additional manufacturing costs and additional license fees., but also because it relies on its own hardware and TV processing system, which says, can optimize HDR10 images without the need for Dolby Vision. Therefore, Samsung has decided to exclusively support the HDR10+ royalty-free dynamic metadata HDR system.

HDR10+ is a direct rival to Dolby Vision and was developed by Samsung in collaboration with 20th Century Fox and Warner Bros.. But with TV makers like Hisense, Panasonic and Philips supporting Dolby Vision and HDR10+, are Samsung users missing out and is HDR10+ really the best option?

Dolby Vision vs HDR10 +

As for the difference between these two formats, Dolby Vision is considered to be more accurate than conventional HDR (displayed in HDR10 format) because content can be encoded frame by frame, meaning what you see will appear more colorful. , dynamic and more suited to the individual capabilities of the television on which it is broadcast.

Dolby Vision IQ compliant televisions can also use light sensors to automatically calibrate picture settings based on the light level in your room.

The maximum specification for consumer televisions using Dolby Vision is up to 12-bit color depth with a possible supply of 68 billion colors. And when it comes to brightness, Dolby allows levels up to 10,000 nits (although no commercial TV currently hits that spec).

HDR10+ is an HDR format created by Samsung, but as a royalty-free standard, content creators and manufacturers don't have to pay high fees to use it.. While the HDR10 standard uses static metadata, meaning the brightness setting is set at the beginning of the content you're viewing and doesn't change, HDR10+ applies a layer of dynamic metadata to the HDR10 stream. So like Dolby Vision, HDR10+ enhances HDR images in every frame or scene, so you get better colors and a lot more tonal detail.

HDR10+ has impressive 10-bit colour, which I think doesn't hold up to Dolby Visions 12-bit color system, but it's worth noting that consumer TVs these days aren't capable of depth depth anyway. But that doesn't mean the technology to deliver 12-bit color won't be available in the near future.

Then, At their core, HDR10+ and Dolby Vision are similar in that they both use dynamic metadata to enhance color, brightness, and contrast, which can enhance any home viewing experience., although both depend on a long list of content creators, distributors and manufacturers. play ball.

There's also the small question of money, as HDR10 + is an open, royalty-free standard, while Dolby Vision requires manufacturers, providers, and content creators to pay a royalty to use the system.

How to watch Dolby Vision

Streaming services tend to stream Dolby Vision and HDR10+ content on a title-by-title basis, meaning that it will not be available for most of the content in a service's library.

There are also many 4K Ultra HD Blu-rays that support Dolby Visionincluding Blade Runner 2049, Wonder Woman, and Avengers Infinity War. But when it comes to streaming services, Netflix, Disney Plus and Apple TV all offer Dolby Vision support – Amazon favors HDR10+.

Dolby Vision is also available through Apple TV 4K, Google Chromecast Ultra, Fire TV Stick 4K, and Fire TV Cube. Almost all of these devices support HDR and HDR10 +, except for Apple TV 4K, which does not support HDR10 +.

media streaming devices The Roku Express 4K and Roku Ultra have also been updated to include HDR10+ support.

Mark Ely, Roku's vice president of retail product strategy, confirmed his support saying, “At Roku, we are committed to providing consumers with easy-to-use products that offer great value and choice. We recently announced Roku OS 10, a free software update rolled out for Roku devices, and we enabled HDR10 + on the new Roku Express 4K +, Roku Express 4K, and Roku Ultra (2020) products for even better viewing. vivid and brilliant experience on compatible TVs.

Dolby Vision on Samsung TVs: Why is it not supported? 1

What can you see in HDR10 +?

Considering that HDR10+ does not require content creators and manufacturers to pay licensing fees, it is surprising that there is not much more support for this format. However, lThe involvement of 20th Century Fox and Warner Brothers means that there are more than 100 Blu-Ray HDR10+ titles on the market, including Bohemian Rhapsody and Wonder Woman 1984.

When it comes to streaming services, Amazon Prime Video has the most content in HDR10+ format. They announced their partnership in 2017 and have continued to go strong by making all of their HDR mastered content available in HDR10+. Google Play, Rakuten, Paramount+, and YouTube are also among those also making sure their content supports HDR10+.

Netflix has yet to adopt HDR10+, but told TechRadar in 2017 that it was ready to support it in the future.. Netflix's senior product manager for its partner ecosystem, Richard Smith, said that Netflix will be open to supporting other HDR formats beyond HDR10 and Dolby Vision.

"We already support HDR10, not the HDR10 + variant, we may support it in the future, but it is not something on our roadmap at the moment," he said.

But I guess we are still waiting for this partnership to materialize. However, Netflix supports HDR10.

For apps like Disney Plus and Apple TV, the services automatically detect your system's capabilities and play content in HDR10 if your TV supports HDR, and autoplay in Dolby Vision if that standard is supported. Upload / available for content as well.

What Samsung TVs are HDR10 + compatible?

The HDR10 + website claims that more than 700 models of televisions, Blu-Ray players, and mobile devices are compatible with the HDR10 + format.

All Samsung UHD TVs made from 2016 will have HDR10+ capabilities. However, newer models like Terrace, Sero, The Frame or the latest QLED and Mini LED ranges will be even better at displaying HDR10+ content thanks to HDR10+ Adaptive, which will use the TV's light sensor to calibrate the picture in response to ambient light, meaning viewers can have a cinematic experience regardless of the viewing environment.

If you have a Samsung TV made between 2016 and 2020, check that its firmware has been updated to take advantage of the HDR10 + feature.

Do Samsung and HDR10 + really support Dolby Vision?

While we don't think HDR10 + can surpass the popularity of Dolby Vision, it certainly can hold its own, especially with the backing of electronics giant Samsung.

Dolby Vision benefits from more advanced technology and support for 12-bit color with brightness up to 10,000 nits. By comparison, HDR10+ offers 10 bits of color and just 4000 nits of brightness., though Samsung's ultra-bright QLED TVs certainly come closer to this latest brightness spec than OLED TVs for Dolby Vision.

The open source nature of HDR10 + can also be tempting for some content creators and production companies, who don't want to pay a premium for Dolby Vision.

What complicates matters is that many televisions and media streamers simply support both formats. Extensive HDR support will be included in both, as well as the HDR10 and even HLG HDR streaming standard, and devices will likely only choose one of the above options.

It's also worth mentioning that HDR10+ technology isn't just available on Samsung TVs. They have also included this format on their cell phones and tablets so you can get 4K video and content on the go. Samsung mobile phone users can even shoot HDR10+ videos on their phones.

HDR10+ and Dolby Vision are likely here to stay for the foreseeable future, and as long as they continue to appear on TVs with exceptional picture quality, there will certainly be room for both.
