The UHD Alliance (UHDA) says it’s nearing completion of premium specifications for products and services incorporating 4K resolution, high dynamic range and other features.

Consumer-driven testing is helping finalize characteristics for the next-generation video standard.

“The Alliance believes that the most compelling next-generation experience delivers 4K resolution, high dynamic range, wide color gamut, high frame rate, immersive audio and other features that create a dramatic new experience for consumers,” UHD Alliance President Hanno Basse said in a statement. “Our consumer testing is designed to help us confirm the possible combinations of features that collectively will help usher in a new era of in-home entertainment.”

At the same time, UHDA is aiding in the development of certification/compliance and logo programs. The Alliance says current activities are focused on hardware and packaged and streamed content but after that it will shift its concentration to specifications and certification/compliance programs for content distributed via broadcast, satellite and cable.

The UHDA, formed in January, says it is nearing 30 member companies. Members include 20th Century Fox, DirecTV, Disney, LG, Netflix and Samsung.

UHD technology uptake among consumers is expected to begin picking up speed.

“IHS expects annual shipments of Ultra HD TVs to grow from nearly 12 million in 2014 to nearly 96 million in 2019, with well over 300 million in use by the end of 2019. With consumers constantly struggling to understand different terminologies, acronyms and feature descriptions, efforts to reduce buyer confusion and improve consistency of the experience benefit not only consumers, but the industry as well,” said Paul Erickson, senior analyst at IHS Technology.

Early UHD supporters like DirecTV are working to drive adoption. DirecTV recently announced the 4K Genie Mini, a small set-top box that enables UHD viewing without a 4K Ready UHD TV from Samsung.
