CEA Reports Characteristics for Ultra High-Definition Displays

June 27, 2014

The Consumer Electronics Association (CEA) has introduced updated core characteristics for Ultra High-Definition (UHD) TVs, monitors and projectors for the home.

As devised and approved by CEA's Video Division Board, these characteristics build on the first-generation UHD characteristics released by CEA in October 2012.

According to a release, these expanded display characteristics (CEA's Ultra High-Definition Display Characteristics V2) - voluntary guidelines that take effect in September 2014 - are designed to address various attributes of picture quality and help move toward interoperability, while providing clarity for consumers and retailers alike.

"Ultra High-Definition 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, 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 CEA's expanded characteristics, a TV, monitor or projector may be referred to as Ultra High-Definition if it meets the following minimum performance attributes:

-Display Resolution - Has at least eight million active pixels, with at least 3840 horizontally and at least 2160 vertically.

-Aspect Ratio - Has a width to height ratio of the display's native resolution of 16:9 or wider.

-Upconversion - Is capable of upscaling HD video and displaying it at Ultra High-Definition resolution.

-Digital Input - Has one or more HDMI inputs supporting at least 3840x2160 native content resolution at 24p, 30p and 60p frames per second. At least one of the 3840x2160 HDMI inputs shall support HDCP revision 2.2 or equivalent content protection.

-Colorimetry - Processes 2160p video inputs encoded according to ITU-R BT.709 color space and may support wider colorimetry standards.

-Bit Depth - Has a minimum color bit depth of eight bits.

CEA's expanded display characteristics also include guidance on nomenclature designed to help provide manufacturers with marketing flexibility while still providing clarity for consumers. Specifically, the guidance states, "The terms Ultra High- Definition, Ultra HD or UHD may be used in conjunction with other modifiers," for example 'Ultra High-Definition TV 4K'.

The Consumer Electronics Association (CEA) is the technology trade association representing the $208 billion U.S. consumer electronics industry.
