14:9

14:9 is a compromise aspect ratio of 1.56:1. It is used to create an acceptable picture on both 4:3 and 16:9 televisions, conceived following audience tests conducted by the BBC. It has been used by most UK, Irish, French, Spanish and Australian terrestrial analogue networks, and in the United States on Discovery Networks' HD simulcast channels with programming and advertising originally compiled in 4:3. Note that 14:9 is not a shooting format; 14:9 material is almost always derived from either a 16:9 or 4:3 shot, and no televisions have ever been made in 14:9.
