Why is the aspect ratio of different programs inconsistent?
The aspect ratio of the content is controlled by the service providers (HBO, Showtime etc.). You can go to the HBO website at www.hbo.com or the ShowTime website at http://www.sho.com and see which programming is in 16:9 HDTV. On the HBO website, you need to look for the little HDTV symbol, and on the Showtime website, it will say “WIDESCREEN” for the 16:9. As time goes on, there will be more and more HD in 16:9 aspect ratio. Whether the HD signal is in 4:3 or 16:9 formats, the picture quality will be better (crisper, clearer, etc.) than an analog or a standard digital signal. The reason for this is that there is up to 5 times the information, or data, for each HD service than there is for standard digital, no matter what the aspect ratio.
