Why is 720p still around?

[nec1912]

Why do they still sale 720P TV's when all blu ray movies are in 1080P and the standard definition is 1080P now?

I thought they would be phasing out the stock of 720P TV's by now?

Or is 720P TV's only for small TV's has small TV's cannot show 1080P do to the small size.

I thought they would be phasing out the stock of 720P TV's .

i guess to give consumers an option to buy tvs. For example, I wouldn't buy a 32" inch or below 1080p. Also, not all broadcast is 1080p yet.

Is any?

Because video games and a lot of HD TV content is still being produced in 720P. Only a handful of games and TV shows are actually broadcast in 1080P. Really, 1080P is only the standard for HD movies, anything else HD is still using 720P.

When did they start broadcasting shows in 1080P? I didn't think anything was and probably wouldn't for a long time. Interesting didn't know that.

CBS and NBC broadcast in 1080i.
1080i is the same resolution as 1080p if your TV performs deinterlacing properly and handles 2:3 and 2:2 cadences.

So with a 1080p set it is possible to watch a lot of 1080p content.

ABC and FOX broadcast at 720p. The only way to see their programs in higher resolutions is to buy them on Blu-ray.

In addition the only way to make sure you're watching these programs in their native resolution is to get them for free OTA with an antenna. Otherwise your cable/satellite provider may be changing the resolution to fit in their bandwidth/system more easily. Some people think when they change the resolution on their cable/satellite box they are changing the resolution of the program, but you're only changing the output resolution of the box.

For example, in Canada Bell takes all signals and converts them to 720p. Hockey Night in Canada on CBC is broadcast at 1080i. If you set the box to 1080i you're taking a 1080i signal that's already been converted to 720p and changing it back to 1080i again, you've lost half the resolution, you should just leave it at 720p and skip an additional conversion step.

You would be amazed how much clearer and cleaner an OTA antenna signal looks than most of the HD channels I've seen from Canadian and US cable/satellite providers.

First, the ATSC specification included a variety of pixel resolution and aspect ratios from 480P 4:3 to 1080i 16:9. The national broadcasting chose two formats that filled the bill for the ability of broadcast electronics to handle a specific amount of bandwidth. If you compare the amount of bandwidth needed for 720P you will see that is is about the same as 1080i.

Why one broadcast network chose one format over the other had more to do with motion artifact that commonly arise in interlaced formats. Hence, it was no surprise that those sports-inclined broadcast networks ABC and Fox chose 720P, and while those not inclined chose 1080i which is what CBS and NBC did.

At this point the consumer electronics association chose to make products for their HDTV standards that fit these two bills, and is why a lot of analog sets were capable of 720P and or 1080i. It wasn't until well after the ATSC standard was adopted in 1995-96, and after the CEA began making serious displays that electronics evolution and a new transport medium started offering content on 1080P.

This new transport form was in the optical media industry and consumerized in the forms of HD DVD and Blu-ray media. Once consumer broadband started picking up in available bandwidth along with much more efficient compression codecs that streaming of 1080P content began to become realized.

But keep in mind that national broadcasters have spent a pretty penny in near term legacy equipment for the ability to broadcast in 720P/1080i and asking them and all of their affiliates to change out again in such a near term of unacceptable, and probably unaffordable by the the bulk of the affiliates.

So, while we can all drool over 1080P asking networks to change out expensive infrastructure to please folks for commercial television isn't probably going to happen for a long time. It will probably be another decade or more before OTA changes are made in the commercial world (which is different from FCC adoptions) and will probably be for higher resolution and skipping 1080P altogether.

If you have a good quality TV, like a samsung or a sony, and it's say 32", 720p it's really good enough. And the price difference quite worth buying it.

What? Than what is Panasonic?

We picked up a 32" for the bedroom for $249. It is 720p which is fine. The HD programing still looks great lying in bed.

Our first Plasma, 42" was 720p And to tell you the truth I don't notice to much difference sitting 15 ft away. Unless of course I had 2 side by side. Then maybe?

[wdaleherring]

I am not a videophile by any means, but I DO notice grain in picture and can most definitely tell if I am watching a DVD or Blu Ray. That said, I had a 50 inch plasma last year that was 720p and now I have a 55 1080p LED and as far as the actual resolution goes, I can't really tell the difference.

Also, 1080p (in my opinion) seems kind of pointless on anything under 42 inches.

I agree.

Quite the opposite for me. Just replaced the 720p DLP in the living room with a 46" 1080p SAMSUNG Smart LED TV. The sharpness of 1080p over 720p was so night and day, the old set went streight into the dog's room to keep them occupied when we're not around. Looking forward to 4K and 8K if/when it comes our way. Expect that it will give the PQ that iPod look.

thats a good question im still puzzled about 1080i i know its for broadcast etc but they could have upgraded by now...

[U4K61]

With much confusion over standards, copy protection and war over 1080i vs 720p, Digital HDTV hobbled into existance in an analogue world: The cathode ray tube, 60 cycle AC, 8VSB vs COFDM modulation... It was a good compromise for something developed in the 80s and rolled out in the 90s. Most affordable consumer sets of the time could not do 1080p. It was 1080i, and if you were lucky, 720p. Times have changed and today's 1080p sets can correctly deinterlace 1080i from 24fps film to 1080p with no loss in PQ if all parts of the system are working correctly. Happy ending.

Someone asked: Why do they still sell 720p TV?

The question is why does anybody bother spending more money on 1080p TV when they could be buying a 720p TV for less money? 1080p is a mess. It's a hoax. It's a gimmic for Best Buy to make more money!

You must read the CNET article (link at bottom)...

Most 1080p TV's in the US have NEVER displayed a single true 1080p image!
Yes, I realize this is a Blu-ray forum and those who post here are the exceptions. Still I say MOST 1080p TV's in the US have NEVER displayed a true 1080p image. Most people do NOT have Blu-ray disc players and or gaming devices with built-in Blu-ray disc players.

BTW, even those with Blu-ray disc players don't watch 1080p most of the time. Right? If your watching Fox or ABC, CBS or NBC you're not getting 1080p. Even if you're viewing a DVD, if the film wasn't originally shot in 1080p then you're not seeing a 1080p image. Am I right?

Please read the following CNET article. I found it sooo interesting. I hope you do, too. I think retailers are so underhanded and the consumers are their victims.

This article is from June 2010 and since then Netflix made a new app. available (Oct. 2010) that allows streaming 1080p but ONLY if you have a PS3 -- and of course the movie you're stream must have been filmed in 1080p or once again, you're not seeing true 1080p images on your 1080p TV screen!

Isn't Direct TV starting to broadcast movies in 1080p?

No, not really. Fox and ABC broadcast in 720p, so yes you're not watching 1080p, but CBS and NBC both broadcast in 1080i which is the same resolution as 1080p. On any set that deinterlaces properly you're watching 1080p as plasma and LCD are not interlaced displays (a few exceptions like the Hitachi ALiS notwithstanding) and they have to convert interlaced signals to progressive signals.

As for film on Blu-ray, it doesn't need to be shot in 1080p to be presented in 1080p. As long as it was shot on a medium that affords resolution equivalent to or greater than 1080p then you can watch 1080p. 4K, 2K, 35mm, 70mm, etc., etc., all afford greater resolution than 1080p.

The hoax is 99% of every thing on TV is not in HD and that 1% in HD 90% of the time is near HD not full HD.And it take 15 to 20 years or more for most of the stuff on TV to be in HD.

The morale of the story is HD is a hoax with a big money drain that does not have market with TV or TV shows,box sets , it is pure blu ray movies non TV.

And that is also why 99% of the TV shows I cannot buy in blu ray.It is going to take a very very very very very long time to phase out DVD / non HD TV and go to full HD.

There is a reason why we switch faster from VHS to DVD than from DVD to blu ray.The studies and production companies gave lost money in DVD and there was kill manality with the record stores.That is why every year less and less VHS to choose from in the store to point you go in store and they would say sorry not in VHS but we have it in DVD.The problem now is they are trying to support blu ray and DVD and there is no kill manality .

And the studies and production companies are giving out pocket change that is the reasone why it is taking for ever to see HD TV shows and big switch to HD and death of DVD and non HD .
