UHD Alliance Releases Official Ultra HD Premium Spec

From UHD Alliance
Enjoying a premium, full-featured Ultra High Definition in-home experience has been simplified for consumers as the UHD Alliance (UHDA), the inter-industry group charged with fostering the Ultra HD ecosystem and promoting the benefits of Ultra HD entertainment technology, today unveiled a consumer-facing logo to identify devices, content and services capable of delivering a premium experience to an exploding Ultra HD market that is expected to grow eightfold by 2019. The UHDA also announced the start of licensing of its ULTRA HD PREMIUM logo.

Developed through the collaborative efforts of leading film studios, consumer electronics manufacturers, content distributors and technology companies, the Ultra HD Premium specifications reflect collective expertise from across the Ultra HD ecosystem, as well as significant input gleaned from experiential consumer testing.

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 widecolor 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.

“The diverse group of UHDA companies agreed that to realize the full potential of Ultra HD the specs need to go beyond resolution and address enhancements like HDR, expanded color and ultimately even immersive audio. Consumer testing confirmed this,” said UHD Alliance President Hanno Basse. “The criteria established by this broad cross section of the Ultra HD ecosystem enables the delivery of a revolutionary in-home experience, and the ULTRA HD PREMIUM logo gives consumers a single, identifying mark to seek out so they can purchase with confidence.”

To ensure products bearing the ULTRA HD PREMIUM logo are certified and conform to the organization’s specifications, the UHDA has designated multiple, independent centers around the globe to handle testing. Companies throughout the ecosystem will work directly with these centers to have their products tested and certified.

The UHDA’s new ULTRA HD PREMIUM specifications cover multiple display technologies and reference established industry standards and recommended practices from the Consumer Technology Association, the Society of Motion Picture and Television Engineers, the International Telecommunications Union and others.

“Ever-rising consumer adoption of Ultra HD TV sets will fuel strong growth for the entire Ultra HD ecosystem over the next few years,” noted Paul Erickson, senior analyst at IHS Technology. “Annual worldwide shipments of Ultra HD TVs are expected to grow nearly 719% over the next several years according to IHS’ forecasts, from nearly 12 million in 2014 to nearly 96 million in 2019, with over 300 million in use by the end of 2019. For the many mainstream consumers looking to make sense of the various terminologies, acronyms and feature descriptions at retail, standardization efforts such as the UHDA’s “ULTRA HD PREMIUM” can reduce consumer confusion and help ensure consistency of both buyer expectations and the delivery of the end experience — benefiting not only consumers, but also the industry as a whole.”

Founded in January 2015, the UHDA has grown to more than 35 companies in two membership categories — Board and Contributor. In 2016, the UHDA will add a third member category, Adopter, for those who wish to license the Ultra HD Premium specifications. Collectively, the UHDA member companies will continue to lead the charge into this new era of home entertainment through advances in resolution, brightness, contrast, dynamic range, color and audio.
