Yes this thread started off useful. Then sort of went off on a tangent there.]]> http://www.dslreports.com/forum/Re-The-is-it-1080p-conundrum-21040006 Mon, 01 Sep 2008 11:55:30 EDT Re: The "is it 1080p" conundrum... http://www.dslreports.com/forum/Re-The-is-it-1080p-conundrum-21030454
While cheaper 60hz would be fine for most interested in mostly normal speed things.

Yes hopefully the thread is useful info for those who haven't leaped yet, to cheap (for a reason... being dumped) 720p supposedly 1080 but really just down converting disappointments

My god your amazing. They create a thread with information and you have to jump in and slam it like all the others.

You say people should go out and do research. Well isn't reading this thread research?

But I guess you want people to look else where for information and not here. Unless of course it is you that is giving the information.

Why not just stay out of it.

Another useful thread polluted.

There's immense confusion and disagreement as to what "1080p" really means.

Just like those that buy a $20K less car but supposedly just like a super BMW... but in the end isn't.

Buyer should self educate themselves. I actually returned a HDTV misrepresented, as 1080p when actually just an down-converting 720p, 1080i compatible set (still 720 image though )

Took a little back and forth but thank you MacWorld accepting the refusal and for for in the end sucking up the $95 shipping charge too (for full refund), after realizing someone just screwed up in the site prod description... though they had already corrected before even shipped, but never notified me... do you still want this inferior version.

And I know how the mistake likely happened a one letter dif in same model number... old and new the same model but 720 being mod# HD, vs the 1080p being same mod # FHD. (FULL HD)

I already HAD a smaller 720 HD, I wanted a larger true HD 1080p understanding the difference.

One of the reasons why some LCD makers are now touting "120hz" devices is because it is a perfect multiple of 24 - where what's called a 5:5 pulldown can be used - more efficient than 3:2 and less error prone).

Summary: 1080p is a resolution. Anything that's displaying 1920x1080 progressive pixel/lines is true 1080p.
Nice definition, but any slightly tech head should know....

And by the way that is how "Film Chains", film projectors in to 30 fps NTSC TV cameras for direct film broadcast on television worked.... rather than single shutter blades the projectors had 5 blades spinning by in the single frame rate... again like 120hz frame rate , 5 times 24 (in mechanical terms) is 120/even multiple as well... so no flicker, and normal look. WHen still working at a TV station, converted old 16mm home movies to video that way... even though 16 fps (the silent standard... 24fps was chosen for sound quality as well as less perceived flicker), but took them to 1" tape in between which had clean variable time base corrented speed, so could get the 24fps procetion, back to 16 fps effective cleanly.

And actually, if those film chain cameras had a silent speed slowed to 15fps rather than 16, then I could have done it directly as that would also be a even multiple of 30, and not really look slow... but they didn't.
Actually a bit better, while some say they can see 30fps flicker I definately can 24 fps when a bright panning scene in the theater... but with even NTSC the 6more fps, and the phosphor persistance, much smoother looking. And agian those old 16mm home movies, with none of the perceived flicker you you definately physically projected at 16fps. (though nothing the interferance/frame rate mismatch flicker you see of film converted to video without compensation)

The 120hz frame rate is more necessary perhapes because modern LCD and Plasma does not have the persistance lag that old CRT phosphors did. (Also why early LCD monitors were resisted for video gaming, until vid card frame rates were upped) Though I havent really noticed it on a 42" HD LCD, I ampretty sure is only 60hz, though might be 120hz in 1080p, my DISH SD, passing through DVD-R is upconverted to. (Looking much better than the S video directly into the TV just doing 480 conversion)

Without getting into too many technical details, here is a summary:

1080p is a display resolution standard - representing 1920 horizontal x 1080 vertical pixels in a Progressive (i.e. not interlaced) format. Anything that is progressive scan (all of the lines are drawn in sequence in a frame) at 1080 lines top to bottom (vertical resolution/horizontal lines) qualifies as "true 1080p".

The frame rate defines how 'often' a display (or for that matter, capture) device produces unique consecutive frames. It is usually referenced in fps (frames per second).

Movies have been traditionally shot on film at 24fps. Major players (like George Lucas from Star Wars fame) have transitioned this 'standard' to the digital era - so nearly all "movies" are shot, even today digitally, at 24fps. This is the 'production' standard. Video (i.e. videotape) has tended to be 30 fps, but varies.

ATSC and DVB broadcast standards support 1080p resolution at 24, 25 and 30 fps.

Once you've got the material to a display device, you then have the problem that most panels operate at 60hz (e.g. 60fps) - so something is needed to translate the signal from it's source format into something the display can understand and output. Hence, the creation of 3:2 pulldown and reverse 3:2 pulldown - allowing a 24fps source to be 'properly' displayed on a 60fps device.
(very detailed information about the telecine process and 3:2 pulldown can be found here.)

One of the reasons why some LCD makers are now touting "120hz" devices is because it is a perfect multiple of 24 - where what's called a 5:5 pulldown can be used - more efficient than 3:2 and less error prone).

Summary: 1080p is a resolution. Anything that's displaying 1920x1080 progressive pixels is true 1080p.
