<p>Ultra-high-definition television (also known as Ultra HD television, Ultra HD, UHDTV, UHD and Super Hi-Vision) today includes <a href="/facts/4K_resolution/Ehhhg0rD">4K UHD</a> and <a href="/facts/8K_resolution/9JXu8uoG">8K UHD</a>, which are two <a href="/facts/Digital_video/xsn9omqG">digital video</a> formats with an <a href="/facts/Aspect_ratio_(image)/I3vbqVl3">aspect ratio</a> of <a href="/facts/16:9/rS5YUsQd">16:9</a>. These were first proposed by <a href="/facts/NHK_Science_%26_Technology_Research_Laboratories/H9rG6zhm">NHK Science & Technology Research Laboratories</a> and later defined and approved by the <a href="/facts/International_Telecommunication_Union/Yn8UKKkw">International Telecommunication Union</a> (ITU). </p><p>The <a href="/facts/Consumer_Electronics_Association/4mwfDzM8">Consumer Electronics Association</a> announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an <a href="/facts/Display_aspect_ratio/hK5LYHN7">aspect ratio</a> of 16:9 or wider and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840 × 2160. In 2015, the <a href="/facts/Ultra_HD_Forum/XQ2hfSBf">Ultra HD Forum</a> was created to bring together the end-to-end video production ecosystem to ensure interoperability and produce industry guidelines so that adoption of ultra-high-definition television could accelerate.
