The Consumer Electronics Association (CEA) has announced updated core characteristics for 4K UltraHD TVs, monitors and projectors for the home.

The new voluntary guidelines build on the first-generation UltraHD characteristics released by CEA in October 2012 and will take effect in September 2014. They are designed to address various attributes of picture quality and help move toward interoperability, while providing clarity for consumers and retailers alike.

"UltraHD TV is the next revolution in home display technology, offering consumers an incredibly immersive viewing experience with outstanding new levels of picture quality," said Gary Shapiro, president and CEO at CEA. "These updated attributes will help ensure consumers get the most out of this exciting new technology and will provide additional certainty in the marketplace."

Under the expanded characteristics, a TV, monitor or projector may be referred to as Ultra High Definition if it has at least eight million active pixels, with at least 3,840 horizontally and at least 2,160 vertically; an aspect ratio of 16:9 or wider; is capable of upscaling HD video and displaying it at UltraHD; has one or more HDMI inputs supporting at least 3,840 x 2,160 native content resolution at 24p, 30p and 60p frames per second. At least one of the 3840x2160 HDMI inputs must support HDCP revision 2.2 or equivalent content protection.

Requirements also include the ability to process 2,160p video inputs encoded according to ITU-R BT.709 colour space ,and may support wider colorimetry standards. And, it has a minimum colour bit depth of eight bits.

The CEA is also working with its member companies to develop a UHD logo to be made available for voluntary use by manufacturers for product packaging, marketing materials and promotional activities.
