It's a simple but good idea. So good that HDTV is going to use it too.
Like the widescreen movie formats, the HDTV screen is formatted much
closer to the way we see. Our field of vision is more rectangular than
square. So, when we view movies in widescreen format, the image fills
more of our field of vision and has a stronger visual impact. After
a few decades of experimenting with ratios, the most common theater
screen aspect ratio is 16:9. HDTV is going to use the same aspect ratio.
However, that's only part of HDTV. Besides a wider screen, the picture
is going to have more detail and crisper images. With the bigger pictures
comes a finer resolution.
