Digital broadcasting allows 1.78:1 (16:9) widescreen format transmissions without losing resolution, and thus widescreen is the television norm. Most television channels in Europe are broadcasting standard-definition programming in 16:9, while in the United States, these are downscaled to letterbox. When using a 4:3 television, it is possible to display such programming in either a letterbox format or in a 4:3 centre-cut format (where the edges of the picture are lost).
