Ultra HD 'Premium' Is For New, HDR-Capable 4K TVs

There's a new standard for high-end Ultra HD TVs, setting clear definitions for picture quality in terms of maximum and minimum brightness, colour depth and input resolution. This might seem boring, but it's the kind of thing that will set a benchmark in quality for the TVs that we buy in 2016 and beyond.

Developed by the UHD Alliance, the working group composed of companies like Samsung, Sony, LG, Dolby and Netflix, Ultra HD Premium is a standard for 3840x2160pixel video, and the devices that capture and display it. It's more concrete and demanding than the original Ultra HD standard, which was little more than a specification for resolution, aspect ratio and bitrate.

The biggest feature of Ultra HD Premium is the mandatory inclusion of high dynamic range, the standard by which new TVs are able to simultaneously display excellent detail in both extremely bright and extremely dark areas of video. Notations for peak luminance and minimum black level are also incuded.

This kind of standardisation is great; such a concrete definition means that only compatible TVs will be able to sport the Ultra HD Premium sticker, and that will serve as a genuine assurance of a cetain level of quality in colour, contrast and overall image clarity. [UHD Alliance]

The UHDA’s ULTRA HD PREMIUM logo is reserved for products and services that comply with performance metrics for resolution, high dynamic range (HDR), peak luminance, black levels and wide color gamut among others. The specifications also make recommendations for immersive audio and other features. These advances in resolution, contrast, brightness, color and audio will enable certified displays and content to replicate the richness of life’s sights and sounds and allow in-home viewers to more fully and accurately experience the content creator’s vision.

    Just need some content..

      The 4K Content from Netflix doesn't count?

      EDIT: Nevermind, mis-read the article.

        hardly a lot of content still. Netflix and YouTube doesn't look the greatest either.
        Even then it has been compressed down looks similar to 1080p

        Compared to vast librabraries of BluRays people have access too - that is content

          OK, by the numbers there is no denying the content is minimal but it's gonna change sooner than what some skeptics think.

          It's taken three years but it looks like we'll finally see the mythical 4K players and 4K BluRays.

          But I won't deny it; only live action which is shot at 4K or even 6K (as is the case with Season 3 of House of Cards) or fresh renders of computer generated movies (Toy Story, Rio and How to Train Your Dragon) are going to benefit for these transfers.

          The only other potential candidates are films on celluloid and that is assuming they were at least scanned in 4K (like with the remasters of Blade Runner) or are in a good enough state to be scanned again in 4K or 6K.

    Reminds me of the days when I was younger, when you battled it out to be the best between ur friends... something along the lines of "supreme commander master of the universe ultra HD premium" :-\

      the Ultra HD Alliance wants you to join them in the fight for the galaxy and defeat the dark lords and ensure the survival of the high dynamic range!

    This is awesome, if only there was one standard for High Dynamic Range content...

    Too bad no consoles can output at 4K let alone UHD Premium. For my screen size, 1080p is just fine though, so no need to worry about my Blu rays yet.

    Good point. I wonder when PS5 and XB2 come out with 4k? If one gets a console out fast it would win a lot of customers.
