‘Uhd blu-ray premium’ logo also coming to players
The UHD Alliance has announced that Ultra HD Blu-ray players can obtain certification to use the Ultra HD Premium logo. This means that the logo is no longer only displayed on televisions that meet the UHD standard.
At the moment, thirty televisions are allowed to carry the logo, says the UHD Alliance. Blu-ray players are now added. The logo should enable consumers to easily find products that meet the standard. “The certification of ultra-blu-ray players is a natural first extension,” said Hanno Basse, president of the alliance.
After uhd-blu-ray players, live broadcasts in uhd may be the next candidate for certification, although there are still some technical hurdles to be overcome in order to develop a premium standard for broadcasting.
Uhd premium is a standard developed by a group of 35 companies, including Dolby, LG, Netflix, Panasonic and Samsung. The group’s existence was announced at CES 2016 in Las Vegas. The standard states, among other things, that for a device to display the uhd premium logo, a resolution of at least 3840 by 2160 pixels must be achieved, a range of at least 90 percent of the dci-p3 color space, a 10 -bit signal for color depth and can use HDR.
It is not known what exactly players must meet in order to qualify for the ‘uhd premium’ certificate, in addition to a paid license by the manufacturer. The standard does contain additional requirements for UHD TVs, such as a minimum brightness for good HDR reproduction, but these do not seem to be available for UHD Blu-ray players. For example, each of those players must be able to play uHD discs with HDR. Moreover, not every manufacturer has rallied behind ‘Ultra HD Premium’. For example, Sony will not carry the logo, while the company will release UHD TVs that meet the requirements.
