I was at Times Square earlier today checking out Fortress, Broadway a few other stores comparing the Analog and DTT signal quality on some LCD tv's and although the DTT signal (on tv's with built in digital tuners) were significantly better, they still seemed quite ''raw'' to me. Not so sharp and kind of grainy. I know that local DTT channels are not HD, except for that one chinese channel but i expected the others to be better than what I saw today.
Anyway, I have this Nowtv HD box and I was wondering if the images for local DTT channels would be any better through it rather than directly into the back of an HDTV equipped with a digital tuner. I came across a thread on this site that seemed to indicate that but i got confused reading all the technical terms.
Also, how do the regular SD cable channels look on an HDtv, I know from my research that they are broadcast in 4:3 and I will have to watch them with the sides blacked out but I did read somewhere that the Nowtv box converts the signal from 480 to 720 which makes it a bit better for viewing on an HD set. Can anyone confirm this, am I making any sense at all?
