OK! I'm really confused now. I'm not a technophile but I'm trying to follow along with this new fangled digital convergence stuff.


Anyway I was talking to a guy @ the local tech shop about plasma and he said that many Plasma's had different native rates while standard analogue television does not have a native rate. So I puffed my self up and declaimed that NTSC native rate was 720x480i.


Sorry he said it did not work that way. He explained all sorts of other things that I solemnly shook my head at but he had lost me by the third sentence.


Is there anyone who has a simpler way of sorting this native rate thing out? And what's with SDTV not having a native rate? Is that possible?


:cool:

720x480i is DVD resolution, I think NTSC is somewhat worse (440x480). NTSC is analog, so technically there aren't discrete pixels on a scan line (the 4 Mhz frequency of the carrier limits how fast the intensity can change, though and thus the discernable vertical lines).

Ahh! Analog. Thats the word I was looking for. So I'm comparing apples to oranges here.


Native rate is peculiar to digital signals and pixels.


NTSC analog is all frequency and wave functions
