In making the transition, which upgrade makes a bigger difference in terms of picture quality and clarity?


480i to 480p (NTSC to EDTV)
480p to 720p (EDTV to HDTV)


Just curious, please elaborate on your answer if you care to.

Anyone else? The results are surprising to me, although the sample size is still small. I though there was a big difference between 480p and 480i.

There is a decent difference between the two, but it still doesn't compare between 480p and 720p. 480p is still 4:3 aspect, while 720p is 16:9. It's a big difference in my opinion.

I assume you must be joking, since the difference between 480i and 480p is how frequently the image is displayed, so there shouldn't be any difference in a still image.

And btw - That was very startling, just quite annoying..

I thought 480i to 480p was a huge difference, until I saw 480i-1080i... Even uninteresting channels are insanely fascinating when it looks that good.

Actually you're confusing the issues, the resolution/scan spec is independent of the aspect ratio. I can do a comparison of a 16:9 film in either 480i or 480p. The difference the poll is referring to is the interlace vs. progressive scan as well as the resolution going from 480 to 720, which has nothing necessarily to do with the AR. :)

The original question is regarding picture quality and clarity. While aspect ratio can be important, I didn't want to get into that here. What do you think about clarity and quality of the two?

I still think there's a big difference between 480p and 720p.

Just a little nitpick 480p sure can be 16:9, that is normally what EDTV refers to (852x480).

But anyway. I voted for the 480p to 720p. Most 480p that you encounter (DVDs) is really just 480i deinterlaced rather than native 480p. But more than that the resolution afforded to you by going up to 720p is just incredible. Think of like this... set your PC to 640x480, not a whole lot of screen realestate to work with, eh? now set it to 1024x768, tons more room to work with... This is sort of like the jump to 720p, there is quite a bit more detail that can actually be used and now seen. 720p has close to 3x the pixels on screen compared 480p.

No contest, 480p to 720p is a far more significant jump in quality.

Seems to me that we should be referring to the most "stunning" difference. If you accept that, then:

There is as much stunning difference between a normal TV and an EDTV (therefore an EDTV capable of 480p with analog basic cable) and I have a Sharp LC-13S1U-S in the kitchen, as

SD (480i or 480p) and 1080i on my Toshiba 57HDX82 (CRT RPTV displays in 1080i and not in 720p).

Of course I prefer HD to ED but this does not take away the marvelous EDTV picture we get with just the basic analog cable with the Sharp. Simply unbelievable compared to a SD tube TV.
