I understand that not all HD stations broadcast everything in HD, so my question is:

Why do SD shows on HD channels look better than SD shows on SD channels? They are both in SD, so why does one look better?

That's SIMPLE....the SD channels on the HD stations are DIGITAL broadcasts so they are NOISE FREE....

And removing NOISE from the Video signal is about 80% of the HD/DIGITAL signal's PURPOSE.....

Make it clean and you won't see loss of detail.....

Sure it's only 480 lines of information, but it's CLEAN....and it does show you how well the 480 signal can actually LOOK....

Pretty.....isn't it.

The SD show on an ANALOG (SD) signal falls victim to NOISE and Signal Loss and [[[Ghosting]]].
and Tint-Shift and other problems....

That's why DIGITAL signals are so good at delivering a PRISTINE SIGNAL.....

You oughta go to a TV station and get a tour of the facility, then look at a production studio's SIGNAL QUALITY on the OLD Analog system....

It's amazing the signal they get......

Because it's being broadcast digitally. With analog, there is always the possibility of minor signal degradation because of distance or interference.

With digital, you either get it or you don't. And if you get it, you are essentially getting a perfect SD broadcast.
