The Ultra HD Alliance has announced an official specification for 4K HDR devices and content, marked with a new Ultra HD Premium logo.

Now that most of us have got our heads around 4K, the Ultra HD Alliance, the industry group in charge of promoting 4K, has announced a new specification to clarify the specification of next-gen devices and content.

The move, announced at CES 2016, is largely triggered by the increasing focus on High Dynamic Range (HDR) 4K content, which is increasingly seen as the optimum Ultra HD experience.

The new specification is called Ultra HD Premium and an accompanying logo will now appear on products and services that conform to the spec.

The Ultra HD Premium spec focuses on "resolution, HDR, peak luminance, black levels and wide color gamut among others. The specifications also make recommendations for immersive audio and other features".

It may sound technical - and, well, it is - but the logo should mean an at-a-glance way for consumers to know exactly what 4K content they're being delivered. And that it should be the 'premium' 4K experience.

More after the break

The key elements of the Ultra HD Premium specification are as follows:

  • Image Resolution: 3840x2160
  • Colour Bit Depth: Minimum 10-bit signal
  • Colour: BT.2020 colour representation
  • High Dynamic Range: SMPTE ST2084 EOTF

Members of the Ultra HD Alliance include LG, Dolby, Netflix, Panasonic, Samsung, Sony, Universal Pictures, Twentieth Century Fox and Warner Bros. So it's pretty much a who's who of the 4K industry.

With this new certificate, does it mean I will have to upgrade my receiver if it already suport 4k? Or is this certificate only for tv's and blu ray players?
