pixel aspect ratio

[QUOTE]Originally posted by SomeJoe

"Standard NTSC DV is 720x480 with a 0.909 pixel aspect ratio."

According to “A Quick Guide to Digital Video Resolution and Aspect Ratio Conversions”:

http://www.uwasa.fi/~f76998/video/conversion/

the pixel aspect ratio (x/y) is 72/79, which equals 0.911, for a sampling matrix of 720X480 on 525-line television systems with 59.94 Hz field rate. This is for DV, DVB, DVD, SVCD, according to the conversion table.

Which is correct, 0.909 or 72/79?

Thanks.
