This might be off topic but my tv does 720x480p. For 480, I thought the res would be 640x480p but that's not the case with my tv, strange huh?
Actually, that's correct. The resolution of a normal television signal is 720x480 (NTSC). The reason it's different is because the pixels on a television aren't perfectly square like that of a computer monitor. The image is still 4:3 ratio, just like a computer's 640x480, but because the pixels are slightly thinner than they are tall (it's a 0.9 pixel ratio), the image ends up being 720x480.. the 0.9 makes it 4:3. It's a bit confusing at first, and it's still kind of weird when I'm working with 0.9 footage on my computer, because it never looks right (everything looks kind of "fat"). I just keep at it, because I know the final output will look exactly as it should when it goes to a television.
Oddly enough, a widescreen image is also 720x480.. hehe. The difference is that pixel aspect ratio.. it goes from 0.9 to 1.2. On a normal TV, it makes the image look "skinny", but a widescreen TV will stretch the image horizontally to fill up the frame. Head over to
http://www.thedigitalbits.com (one of the best DVD news sites, by the way), and look for the link about "Anamorphic Widescreen". That's what all DVDs use for widescreen images, and it's also what the current generation of game systems use. It's possible that the next-gen systems will be able to produce a native widescreen image, but we don't know where the industry is going yet.. even the Blu-Ray and HD-DVD movies may still use anamorphic, just to fit more on-screen and maintain compression.
tha_con: to be perfectly blunt, you don't know whether it's "fake" or not. Unless you happen to have a PS2 dev kit sitting in your living room, there's absolutely no way you can tell what the actual exported signal's resolution is. Even if it's upscaled, the output resolution is still 1080i (it has to be, in order for the TV's to even recognize it). And because of that, the aliasing
will be reduced. Which will still look better, even if it's only by a small margin. If a gamer has an HDTV capable of supporting a 1080i signal, there is absolutely no reason why they shouldn't use it.
