Odd aspect ratio
On Travel Channel HD, I notice some HD programs are broadcast in this odd aspect ratio in which the picture fills the top and bottom of the screen and there are thin bars on left and right. It's somewhere between the 16:9 (or 1.78) full HD and 4:3 (1.33) SD. When I measured the picture dimensions I got an aspect ratio of about 1.55.
Anyone know the origin of this ratio?
