The UHD Alliance (UHDA) today announced the Mobile HDR Premium specification and logo for portable devices including smartphones, tablets and laptops.
The new designation will be for devices that meet UHDA-defined performance criteria for resolution, dynamic range, color space and bit depth and delivers a consistent premium experience.
“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 in a statement. “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.”
In particular, the new HDR specification sets parameters for devices including smartphones with 3- to 7-inch screens, tablets with 7- to 12.9-inch screens, and laptops with 9.5- to 18-inch screens. In each of those instances, to meet the specification those devices will need to display a resolution of 60 pixels/degree, dynamic range of .0005-540 nits, 90% of P3 color gamut, and a bit depth of 10.
As video consumption continues to shift more toward mobile and multiscreen, and away from traditional linear viewing on a large-screen TV set, it’s important for the UHDA to expand its purview to encompass smaller screens.
Last year the alliance—which now counts 50 member companies and board members from Amazon, Dolby Laboratories, Netflix, Panasonic, Disney, Twentieth Century Fox, Universal Pictures, Warner Bros. Entertainment and others—used CES to launch a similar UHD spec for TVs.
"The diverse group of UltraHD Alliance 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 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."
