For comparison other standards are:
240 - VHS (ditto Betamax)
330 - NTSC broadcast
425 - laserdisc (ditto S-VHS)
540 - DVD

I was a bit surprised, but apparently the Electronics Industry
Association measures the resolution differently than one might
expect. They put a giant circle in the middle of the screen, count
the number of visible pixels across, and arrive at a number like "425
for laserdisc" or "540 for dvd". It seems counterintuitive, but
that's how it's done.

I imagine if the DVD is severely compressed, the quality would drop
much lower than 540 (just as a VHS tape recorded in super-slow mode is
only ~120 across). 540 is the ideal, not the norm.

First is the signal. I had understood NTSC to be 525 each way, (for a video
camera)
Second is the display - there are regions of the signal ( top & bottom)
which are not displayed on the screen


So what you actually see is less than what is recorded. The technical
sections of sites like digitalfaq explainm this properly.

Don't confuse HORIZONTAL resolution with VERTICAL resolution.

525 is the VERTICAL resolution of NTSC. Of those 525, only 480 actually
carry picture information. The rest are for sync, closed captioning, and
other digital transmission features (parental control, XDS,
TVGuideOnScreen, timecode for VCR's, etc...)

The 240/330, etc mentioned above are rough HORIZONTAL resolutions.

For reference, the HD resolutions are:
1280(h)x720(v)
1920(h)x1080(v)

expressed in pixels, but expressed in "lines of resolution per picture
height". This is the standard method for defining analog resolutions in the
4:3 format. To get to pixels (approximately), these numbers have to be
multiplied by 1.333.

Anim8r is an internet stalker. He follows me around from forum to

starting to scare me. I may have to seek legal action.

Hang on, 'resolution' is the number of tiny dots while 'pixel' is the
