Resolution question

----- HDTV Magazine Tips List -----

Resolution and aspect ratio are two different things.

16:9 is an aspect ratio (width:height)

720x480 is a resolution. To produce a 4:3 or 16:9 from a DVD with
720x480 resolution, the pixels are not square, since 720x480 is 3:2.

Anthony,
Pixel shapes/sizes are not consistent from one panel to another. The
720:480 pixel rate you have works to 1.5:1, not a standard aspect ratio.
Theoretically a 480 vertical would work to 640 horizontal to be 1.33:1 (4:3)
and a 16:9 would be 854 pixels wide for a 480 vertical.
Cheers,
Joe

A friend has a question regarding resolution. I think
the way he phrased it is confusing me, but perhaps
it's just me. Anyone out there willing to take a
crack at what I think is something simple? Here goes,

If 4:3 is 720x480 or 486, what is 16:9 in terms of
resolution?

either 1920x1080 or 1280x720. anything less is not HD. Some sets have
fewer horizontal pixels and still maintain 16:9 by stretching the pixels
(not square, but rectangular pixels).

It should also be pointed out that the 720 and the 480 are lines of
resolution related to an analog response which does not use pixels.

As for 16:9 resolution that currently maxes out at 1920 or 1280 using HD
sources but that says nothing about resolution of how the the image was
captured or mastered nor the display and it's capability.

Bottom line is aspect ratio and resolution can be independent from one
another in terms of response and one does not by definition denote the
other.

Extended definition displays can be 16:9 and some front projection CRT
can do 1920 in a 4:3 aspect as an example...
