1080p - Time for a reality check!

cliffs: you did good my being a poor m0f0 and not running out to buy this stuff that isn't compatible with 1080p.
Looks like that more quite some time 1080p will be left to pcs
Good read. Makes me happy I bought a 1080i last winter.
Cliffs:
-There are no fast refresh (30Hz or 60Hz) 1080p production or transmission formats in use, nor are there any looming in the near future ? even on the new HD-DVD and Blu-ray formats.
-The bandwidth is barely there for 1080i channels, and it?s probably just as well, because most TVs wouldn?t support 1080p/60 anyway
- they?d just convert those signals to 1080i or 540p before you saw them.

I scanned the article for 20 seconds and quickly realized he has no clue what he is talking about.

"To get your attention, marketers are referring to 1080p as ?full spec? HD or ?true? HD, a phrase also used by more than one HD veteran in the broadcast industry. We?re hearing about ?1080p content? coming out of Hollywood, from broadcasters, from cable systems, and from direct broadcast satellite services."
That's a new one on me.
"First off, there is no 1080p HDTV transmission format. There is a 1080p/24 production format in wide use for prime time TV shows and some feature films. But these programs must be converted to 1080i/30 (that?s interlaced, not progressive scan) before airing on any terrestrial, satellite, or cable TV network."
umm, no.
"What about live HDTV? That is captured, edited, and broadcast as 1080i/30. No exceptions. At present, there are no off-the-shelf broadcast cameras that can handle 1080p/60, a true progressive format with fast picture refresh rates. It?s just too much digital data to handle and requires way too much bandwidth or severe MPEG compression. (Consider that uncompressed 1920x1080i requires about 1.3 gigabits per second to move around. 1080p/60 would double that data rate.)
"
We're talking diplays here...a very good de-interlacer could still provide a very pleasing image. Has this yahoo ever watched a DVD?
That's where I dismissed this moron.

Still think you?ve just gotta have that new 1080p RPTV? Wait until you see what standard definition analog TV and digital cable look like on it?
Hah! He knows EXACTLY what he's talking about!
Hah! He knows EXACTLY what he's talking about!
This year's Samsung DLP 1080p sets accept a 1080p signal via the HDMI inputs, HP sets have since last year.
Some newer AV receivers offer 1080p switching.
At least some HD-DVDs are already being mastered in 1080p even through first generation players only output 1080i.
We don't know yet whether the PS3 will output blu-ray discs in 1080p.
Cliffs of article: a $300 HDTV won't play 1080p content, and cable is 1080i. so the feature is worthless.

I'll be honest, I don't know very much about HDTV and I don't know how credible this is, but I know a lot of people on here have been advocating how great 1080p is/will be.

Thoughts?
For some background for you...
1) digital video processing has advanced leaps and bounds in the last 6 years in terms of price and power - what you couldn't do back then for 1500 bucks on the processing alone is now on a few chips for a few dozen bucks.
2) I'm too lazy to discuss the advantages of a progressive display over another one that offers higher resolution.
3) 1080p is the best of both worlds and digital processing is to the point where IMHO it is able to handle the conversion and IMHO is more pleasing to the eye.
The article listed is so full of BS that I'm laughing at it. It's like those that said "SACD and DVD-A are terrible because you can't hear a difference!!" Well there are those of that can hear a good recording and want our speakers to produce exactly what we give them. Same with displays.
I don't care if it's crap or not, I couldn't afford a 1080p TV, so I have a 1080i TV. Still looks good to me.
Nothing wrong with 1080i, the article author is just a moron for saying that a 1080p set offers no additional value.

I have to chime in here and strongly disagree with Spidey.
1080p, for the most part, is pure marketing hype.
The author makes several very good points which cannot simply be waved away.
The fact of the matter is, in most application IT IS better to have 1080 lines of resolution. But like a few other things in life, it's not necessarily the number of pixels on your display that matters most-- its how you use them.
Currently, the fact of the matter is that so very few displays which are capable of actually displaying a 1080p signal can actually accept it.
Even those that accept a 1080i signal do nothing but discard the odd or even frames-- the hardware and algorithms necessary to properly deinterlace 1080i are too complicated and expensive for manufacturers to include in their set. They are banking on the fact thay you as a consumer will say "ZOMG! 1080 lines of resulotion rocks my world!!!" to notice that what you are watching is essentially 540p.
Dare I mention the dearth of 1080p content outside of a PC?
And don't bet on cable or satellite coming through anytime in the next decade with 1080p-- they don't have the bandwidth they fully need to do the few channels they already have in 720p or 1080i justice.

HOW-TO Scaling the sea of HD
- A common trap many consumers fall into occurs when they purchase an HD or 1080p capable display and hook up all of their video sources. The assumption is that every DVD they own and all of their favorite TV shows will magically look better because of the shiny new plasma TV. Many consumers simply aren?t making the connection that you have to actually be watching the High-Def feed of a program or source in order to enjoy the HD benefits. They think that because their TV has a "High-Def" logo on it, everything is high def when in fact the opposite is true. Blowing up an NTSC image on a 50-inch plasma TV makes it look worse than it did on a 32-inch direct view TV.
