High-definition television

High-definition television (HDTV) provides a resolution that is substantially higher than that of standard-definition television.

HDTV may be transmitted in various formats:

The letter "p" here stands for progressive scan, while "i" indicates interlaced.

When transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television).

History

The term high definition once described a series of television systems originating from August 1936; however, these systems were only high definition when compared to earlier systems that were based on mechanical systems with as few as 30 lines of resolution. The ongoing competition between companies and nations to create true "HDTV" spanned the entire 20th century, as each new system became more HD than the last. Ironically, in the beginning of the 21st century, this race has continued with 4k, 5k and current 8K systems.

America (advertisement)

"America" is an American political advertisement released by the 2016 presidential campaign of Bernie Sanders. It premiered on January 21, 2016 via YouTube, and to air on television in Iowa and New Hampshire shortly before the Democratic Iowa caucus and New Hampshire primary.

Content

The advertisement features "America," a song recorded by Simon & Garfunkel for their album Bookends (1968).

The ad starts with scenes of everyday American life over soft humming and gentle guitar strumming. As the line, "let us be lovers, we'll marry our fortunes together" plays in the background, a middle-aged couple dances at a small Bernie Sanders for President rally. Then Sanders is seen speaking to a few people in a backyard. As the ad continues, the crowds grow larger and more enthusiastic. A montage of many Sanders supporters appear, as the words "They've all come to look for America" flash on the screen. Sanders is then seen addressing a large outdoor gathering, interacting one-on-one with supporters, appearing before more energetic crowds, finally ending in a large auditorium filled to capacity with cheering people.
