View Full Version : NTSC Resolution?
zedrein 11-22-08, 02:21 PM OK, so I'd just like to know the resolution for a standard 4:3 tube set - Like if I walk into a Sam's Club and grab just a normal looking set that we we're all used to for years off the wall, what is going to be the resolution?
Will it be the same for all of the 4:3 tube sets? Were there some exceptions? I know there was such thing as EDTV, but I think that was a widescreen format if I'm not mistaken, no the 4:3 ratio I'm talking about.
Thanks for the help guys.
NTSC (Preferred Format) format uses a 648 by 486 resolution.

I believe you are. I've never seen a 4:3 autoset the vertical raster shrink when fed 480p. DVDs and SD ATSC are 480i.
Interestingly, Guitar Hero World Tour is the only PS2 port I've encountered with no 4:3 setting. Still starts up interlaced every time. It's tradition.
Jack White 11-25-08, 05:36 PM It depends on the set. I've seen some Sony XBR RPTV sets with 1000 lines of horizontal resolution in old Crutchfields. Horizontal resolution is measured across 75% the width of the screen so a set with 1000 lines of horizontal resolution will have roughly 1333x480+ horizontal resolution.
All NTSC sets have 480+ visable scan lines, but the horizontal resolution is different with each set. Some sets only have 270 lines of horizontal resolution, while others have 600, 800, and even 1000.
Horizontal Resolution Wedge Patterns such as in Aiva or VE can tell how much your set is pushing.
It also really depends on the source material. Analog OTA has 330 lines of horizontal resolution(440x480+). C-band has 528 lines of horizontal resoluiton(704x480+). DVD has 540 lines of horizontal resolution (720x480+).
VHS has 240 lines of horizontal resolution (320x480+). Laserdisc has 430 lines of horizontal resolution (573x480+). Dish Network, Cable, and Directv are so OVERCOMPRESSED that resolution becomes meaningless.

DVD resolution is 540 vertical by 720 horizontal.

trivial 11-26-08, 11:23 AM 540 would be nice for native 1080i displays, but that's false. DVD=720x480

That would make the "DVD Demystified" book and everything else I have seen false.
Note the term in the first sentence in the link you provide, "theoretical maximum".
From a few souces (google):
The standard DVD resolution is 720x480 pixels, or 345,600 pixels in each frame.
At 29.97 or 23.976 fps (usually used in regions where NTSC is standard):
720 × 480 pixels MPEG-2 (Called full D1)
A standard DVD player, without upscaling, can output video resolution at 720x480 (480i). A progressive scan DVD player, without upscaling, can output 720x480 (480p - progressive scan) video signals.

Not disagreeing with the 540 vs 480, I am saying 720 is the horizontal.

Oh... didn't sound like that from posts #5 and #7. ;)
Anyway, maybe there's a disjoint in the terminology.
