HDR10 is a technology developed by the UHD Alliance and it’s starting to be supported by TVs and devices, such as Roku, Apple TV, Chromecast Ultra, and so on. Dolby Vision is a technology developed by Dolby Laboratories
What Is HDR10?
HDR10 is an open standard that allows 4K content owners to deliver HDR video, mastered in Rec 2020 color space, to consumers with compatible TVs. The goal of the UHD Alliance’s HDR working group was to develop a royalty-free specification that ensures every manufacturer will provide an interoperable implementation of HDR technology. The UHD Alliance technology group first formed a UHD Phase A Task Force to define a common HDR specification. The result is the publication of E-UTRA, Generic Coding and Configuration Guidelines for High-Efficiency Video Coding (HEVC). The guidelines provide a clear definition of how HDR services will be encoded into Ultra HD TV streams.
The UHD Alliance announced HDR10 as the specification for Ultra HD Premium during CES 2016. Regular updates to this spec are already in the process of adding new features and functions.
What Is Dolby Vision?
Dolby Vision is a proprietary HDR technology that allows content creators to author movies or TV shows that can be displayed with dynamic range, based on what’s on-screen, that results in enhanced brightness and contrast as well as a wider color gamut. This means that the TV has to be able to display more colors than HDTVs do today or it won’t be able to display all of the colors authored into the content.
At the same time, Dolby Vision allows for scene-by-scene adjustments, which can optimize at each step what is being displayed on the screen. The result is improved picture quality since HDR TVs should not have to constantly switch back and forth between different shades or brightness levels throughout a movie or TV show.
HDR10 Vs Dolby Vision
You may still be wondering why you should even consider buying an LG OLED TV if you already have an HDR10 capable UHD TV and can’t take full advantage of all that Dolby Vision has to offer. Well, there are several reasons why you should seriously consider buying an OLED TV with Dolby Vision today.
First of all, not every movie or TV show is available in the Dolby Vision format, but more and more content owners such as Warner Brothers and Sony Pictures are releasing their titles in both formats. Secondly, most non-LG 4K TVs will only support HDR10 which means they won’t be able to play any titles in the Dolby Vision format even when said titles become available in this format, and finally your current UHD TV only supports up to HFR (High Frame Rate) of 60Hz meaning it can only play content coded at up to 60fps. This is where OLED’s true advantage lies because their infinite contrast ratio allows for blacker blacks and brighter whites that are not possible with LCD/LED TVs which means the difference between 24fps and 36fps doesn’t show up as much on an OLED TV as it does on a 4K UHD TV with just HDR10 support.
Another of the differences between these two formats is how each one treats metadata during playback. Dolby Vision supports static metadata which remains unchanged through playback while HDR10 supports dynamic or changing metadata, so if your receiver or AVR does not handle switching the source from HDR10 to Dolby Vision content, you could be stuck with a picture that doesn’t look as good as it should.
