CES2016: UHD Alliance present ‘UHD Premium’ standards for UHD and HDR

The UHDA, formed a year ago, comprises of the biggest players in the global content creation and distribution industries. Their primary goal is to “Define a next generation premium audio-visual entertainment experience”, and at CES 2016 they have announced their first major step.

The UltraHD Premium ‘standard’ is not a format, like we have from the SMTPE for colour spaces (BT.2020, REC.709 et al), but as explained by UHDA President Hanno Blass – who is chief technology officer at 20th Century Fox – it is “…parameters that define the quality of the experience.” This is great news for content creators and consumers. Those of us looking for a UHD TV in the coming months will start to see this logo being used to show that the model complies with various requirements covering resolution, bit depth and colour spaces.

Blass provided the following details on these specifications that manufactures will have to meet to be legible for licensing the logo onto their devices:
