16:9 Aspect ratio of an HDTV signal which is 16 units by 9 units, whatever
size those units may be. In the film trade aspect ratios are described
in relation to one, which means this aspect ratio is described as 16/9

viewed on a NTSC video device. To accomplish this, 4 frames of film
are converted to 5 frames of video by inserting an extra field of film
frame every other frame.
