To bare the Ultra HD Premium logo, those sources will have to conform to the same specification as 4K TVs and Ultra HD Blu-ray players, which includes support for 4K, high dynamic range (HDR), a wide colour spectrum and 10-bit colour depth.
The expansion makes sense considering the increasing number of 4K sources available; 4K set-top boxes are now firmly a ‘thing’ thanks to the likes of Sky, BT and Virgin, and the Google Chromecast Ultra and Amazon Fire TV - and possibly an upcoming 4K Apple TV – are strongly representing 4K media streamers too.
“With 4K UHD TV shipments increasing by 42% to 81 million in 2017, the one constant in a continually and rapidly changing content delivery environment is the consumer demand for a premium content experience regardless of the delivery platform,” said UHD Alliance chairman Michael Zink.
The Alliance has also emphasized its increasing focus on monitoring and maximising interoperability between products and is also broadening its consumer education efforts with plans to launch a website, videos and brochure focusing on UHD technologies.
The Alliance anticipates that product testing and licensing for media streamers, set-top boxes and PCs will begin in “early Fall” this year.
