What I've noticed hereabouts recently is that when KFMB-TV airs CBS 4:3 cbs
programs, they place a somewhat subtle "HDTV" in grey on pastel on the left
otherwise black area, and their channel number and the CBS logo on the right
side of the screen.
I've also seen - at least once - a subtle gradation from black to grey. I
can't remember where I saw it.
I won't watch - for more than a second - a channel with stretched video.
KUSI-DT does it hereabouts; the Chief Engineer told me that was 1) because
there isn't much syndicated HDTV content (pathfire doesn't transmit it yet)
and 2) because he's airing 720 60p, and wants people to think it's all HDTV.
For many of us, the stretched video says something is a bit off-tune.

For 16:9 formats like 1920x1080i or 1280x720p, 4:3 content should
be pillerboxed in the frame. IMHO, that should be the end of the
story, but of course, it's not.
Some networks (mostly cable networks) like to send 4:3 content
that fills the 16:9 frame. There are two possible reasons for this:
1) Prevents burn-in of the display at the expense of image distortion.
2) Assumes the typical HDTV is 4:3.
I think we can all agree that reason #2 no longer applies. For reason #1,
it pains me to go to sports bars and see short fat images on 16:9 displays.
At home, I just refuse to watch the cable networks that stretch their 4:3
content.
Since 4:3 content isn't going away anytime soon, the correct path of action
is to advance the display technology to prevent burn-in.
