Ultra-high-definition television

Ultra-high-definition television (also known as 2160p, UHD-1, Super Hi-Vision, Ultra HD television, UltraHD, UHDTV, or UHD) includes 4K UHD (2160p) and 8K UHD (4320p), which are two digital video formats proposed by NHK Science & Technology Research Laboratories and defined and approved by the International Telecommunication Union (ITU).

The Consumer Electronics Association announced on October 17, 2012, that "Ultra High Definition", or "Ultra HD", would be used for displays that have an aspect ratio of 16:9 and at least one digital input capable of carrying and presenting native video at a minimum resolution of 3840×2160 pixels.

Alternative terms

Ultra-high-definition television is also known as Ultra HD, UHD, and UHDTV. In Japan, 8K UHDTV will be known as Super Hi-Vision since Hi-Vision was the term used in Japan for HDTV. In the consumer electronics market companies had previously only used the term 4K at the 2012 CES but that had changed to Ultra HD during the 2013 CES. The Ultra HD term is an umbrella term that was selected by the Consumer Electronics Association after extensive consumer research.

Lionel Messi

Lionel Andrés "Leo" Messi (Spanish pronunciation: [ljoˈnel anˈdɾes ˈmesi]; born 24 June 1987) is an Argentine professional footballer who plays as a forward for Spanish club Barcelona and the Argentina national team. Often considered the best player in the world and rated by many in the sport as the greatest of all time, Messi is the only football player in history to win the FIFA Ballon d'Or five times, four of which he won consecutively, and the first player to win three European Golden Shoes. With Barcelona he has won seven La Liga titles and four UEFA Champions League titles, as well as three Copa del Rey titles. A prolific goalscorer, Messi holds the records for most goals scored in La Liga (299), a La Liga season (50), a calendar year (91), a Champions League match (five), and most Champions League seasons (five).

Born and raised in central Argentina, Messi was diagnosed with a growth hormone deficiency as a child. At age 13, he relocated to Spain to join Barcelona, who agreed to pay for his medical treatment. After a fast progression through Barcelona's youth academy, Messi made his competitive debut aged 17 in October 2004. Despite being injury-prone during his early career, he established himself as an integral player for the club within the next three years, finishing 2007 as a finalist for both the Ballon d'Or and FIFA World Player of the Year award, a feat he repeated the following year. His first uninterrupted campaign came in the 2008–09 season, during which he helped Barcelona achieve the first treble in Spanish football. At 22 years old, Messi won the Ballon d'Or and FIFA World Player of the Year award by record voting margins.
