On two different TV sets tuned to WLIO DT 8.1, the image does not fill the screen but is, instead surrounded by a black "frame." In comparison, WLIO DT 8.2 and 8.3 and the other area digital signals fill the screen.
Any ideas of what's happening?
WLIO-DT sends out a signal in 16:9 format, which is standard HD.
When we’re transmitting SD, you should see a black band on either side of the picture, since SD does not fill the picture from side to side.
If you’re seeing black bands on the top and bottom, that usually means that the set needs to have the aspect ratio changed. On some sets we’ve noticed that the button on the TV is called “aspect”, on others it’s “picture”, and on still others it’s called “size”. Once the 16:9 mode is selected for WLIO, then it should stay that way.
We do not “fill” the HD screen with SD programming, stretching the picture to make it look HD. Other stations do it to make it look like HD. That, in my opinion, is not HD or true 16:9 format. Plus it distorts the picture by putting everything out of correct aspect ratio.
