Its not a coincidence, its an artifact of the power source and the color information in the country, you are acting as if they resolution was decided independently, it most definitely wasn't.
Actually, I'm not. I wonder where you get that idea!
PAL is a tweak of NTSC (color). Do you suppose that the phase is reversed every alternate line _only_ for 50Hz countries? Hmmm.. why do that? No, the color systems are independant of refresh rates & number of scan lines.
Which part of MPEG2 D1 streams did you not understand?
Well, according to what I've read D1 doesn't exactly define a certain resolution.
As for the Pal 60 format you talked about, or the PAL I, PAL N, etc all of them are based on different frame rates, sizes because of local conditions, this basically proves my point not yours
But that IS my point.
My point all along was that PAL is independant of resolution/framerate. And you argued against me, and now you're arguing exactly what I was arguing - contradicting yourself, mind you - and now telling me that I was wrong??
In addition, understand NTSC started out as a monochrome format at 60 Fields, and 525 lines (not all viewable), there was no color, so implying that NTSC only has to do with color is silly, it was a monochrome spec (adopted in 1941), we later added the color carrier wave with NTSC II,
I know. I'm using 'NTSC' in the context of NTSC Vs PAL, as in the differences in color signal (obviously, PAL only existed after color NTSC).
DVDs are sold as PAL and NTSC formats for a reason, even D-VHS is sold in PAL and NTSC formats unfortunately.
Hang on, didn't you just 'agree with' my point about color signals (ie NTSC Vs PAL) as being independant of resolution/framerate?
Anyway, that doesn't mean that what's recorded on the media (especially in the case of digital) is PAL or NTSC. It's really neither.
Geeeezz...
