The the UHD Alliance has just defined the HDR "premium viewing experience" for battery-powered devices with their announcement of the specification and logo for portable devices: "MOBILE HDR PREMIUM."

The UHDA's MOBILE HDR PREMIUM designation confirms that a device meets UHDA- defined performance criteria for resolution, dynamic range, color space and bit depth.

"The dramatic improvement of screens in battery operated devices, coupled with the emergence of 4K and 4K with HDR streaming offerings through services such as Amazon, Netflix and others, makes it possible for consumers to get a much richer and more immersive experience on their computers, tablets and smartphones," said UHDA President, Hanno Basse. "The expansion of our certification of logo program will help consumers identify premium portable products that take full advantage of the wealth of HDR content coming to market."

The mobile category surpassed the in-home category in consumer entertainment device spending in 2013, and Statista predicts that mobile video internet traffic, which is currently over 3.5 million terabytes per month, will reach nearly 23 million terabytes per month by 2020. Ooyala's Global Video Index found that 52 percent of all video streams in the third quarter of 2016, both short and long form, were viewed on mobile devices.

Since its introduction, consumer adoption of Ultra HD hardware and software has seen growth with an estimated 100 million households worldwide currently enjoying an Ultra HD experience, and by 2020 it is estimated there will be 450 million UHD TV households.

The UHD Alliance was founded in April 2015 by 10 companies and now counts more than 50 companies. The UHDA unveiled its Ultra HD PREMIUM certification and logo program for televisions and pre-recorded content at CES 2016, followed by certification of Ultra HD Blu-ray players last April.
