Default Upscaling to 1080i vs 1080p DVD for 1080p LCD

I am in the market for a new DVD player and am looking at upscaling DVD players.

My questions are about the difference between a 1080i upscale vs. a 1080p upscale.

I think my tv (Samsung LN-T4061F) will deinterlace a 1080i input from the DVD player and display a 1080p picture. Is this correct?

Or should I purchase a 1080p upscale player?

Also, any recommendations for players?

A lot of people rave about the Toshiba HD-A2. It will play HD DVDs as well as upscale SD DVDs to 1080p. You might look at this player.

For less $$ there are a lot of good DVD upsalers out there now in the $50 -$100 range that will output at 1080p as well.

1080p and 1080i are about the same thing. All current TV's deinterlace signals to progressive scan. Assuming your TV deinterlaces reasonably well, the 1080i may be a slight advantage since it goes through one fewer scaling step in the DVD player.

I recommend the Toshiba A2. Not only does it upscale very well but it also plays HD DVD's. You can find a refurbed unit for less than $190. A brand new one is about $235. For me it doesn't make sense to buy an SD player when you can find HD for a few bucks more (assuming you don't need SACD or DVD-audio which it doesn't handle.)

If your display doesn't accept a 1080p input, then there is no point in getting a DVD player that upscales to 1080p.

Assuming the player is at least a half-way decent upscaler, there will be no difference in the 1080i and 1080p output data anyway, the only difference is in how the data is transmitted to your TV (odd lines followed by even lines for 1080i and all lines in order for 1080p).

Before you go investing in a new player though, be aware your display already upscales DVD's to 1080p (by virtue of it being a fixed-pixel display like all LCD's) and there is a good chance the upscaler in the display is as good or even better than any given upscaing DVD player, so be sure to compare.

His set IS a full 1080P set and does accept 1080i/p signals.

A good (Oppo, Denon, etc.) up scaling DVD player will provide a far better signal and will result a superior picture. If HD TV's could up upscale that well, there would be no need for any HD signals. . .

But the earlier poster is correct-- go for the real HD player! An A2 cost just a few dollars more than an a good up scaling player-- and does a very fine job of upscaling also. If Audio is important-- then an Oppo is a very good player to own while you wait for the price of the Blu Ray players to come down. If you like HD-DVD-- then go for the A2 NOW!

Let's not confuse the issue. Upscaling an SD signal allows it to match the pixel resolution of the TV screen. It doesn't contain as much detail as HD. A TV can upscale to its heart's content but it is only interpolating the "missing" pixels. It doesn't have them to work with in the first place like an HD signal has.

What's the correlation between whether "a good upscaling DVD player will provide a far better signal and will result in a superior picture"??? and the conclusion that "if HD TVs could upscale that well, there would be no need for any HD signals"???
I mean, does this mean that since a "good upscaling DVD" provides such a superior picture that there is no need for HD signals??? That seems to be what you are saying.

The upscaling that is performed in an upscaling DVD player to convert 480i to 720p or 1080i/p, and the upscaling that is performed in the HDTV to convert 480i/p to the native resolution of the display are the same process--interpolation.

Some scalers have better algorithms than others to preserve and enhance details. There is no way of knowing in advance whether the scaler in a given DVD player is worse than, as good as or better than the one in a given HDTV.

The best upscaled 480i/p DVD will not look as good as the best true HD signal, as the HD image contains more fine details that simply aren't there in an upscaled image and can't be added via interpolation.

Let me try again:

To paraphrase what Rick-F said:

"If HD TV's could up upscale as well as a good up scaling DVD player, there would be no need for any HD signals. . ."

I was just trying to figure out if he really meant what he said.

Sorry, I wasn't responding to your post but to his.

I don't follow his logic.

Upscaled SD isn't as good as a real HD image, regardless of whether it's coming from an SD DVD or from an SD broadcast. Upscaling is the same process whether it is peformed in a DVD player or in the display.

Yes, the quality of upscaling varies from product to product and model to model. There are quite a few HDTV's with better upscalers than in the typical upscaling DVD player.

I have a 1080i rear projection CRT TV. I was going to grab a Sony DVPNS77H that upconverts to 1080p. I realize my TV will not display this. Is this a waste of money as opposed to say a SONY DVP-NC85H?

I don't think you will beat the upscaling of an Oppo Digital regardless of 1080i or 1080p. The only exception within a reasonable price would be a Toshiba HD DVD player which does a great job of upconversion, or maybe the newer BD players.
The only thing 1080p will buy you is future-proofing if you change up your display.

If 1080p is the only difference and you're not buying for the future, then yes, it would be a waste of money.

But if you're buying for the future, buy a Hi-Def disc player, as they are some of the best upscaling players on the market and you get to watch real HD as well.

I am just getting something to tide me over. I picked up a NS71HP and it caused a lot ob background noise in the picture. I sent it back. I have a Sony player now that is dying. I want to fill the gap for Blu-Ray or HD. I will pick up the 85H. I can get it pretty cheap now.

If you are getting something to just tide you over then just get a good progressive scan DVD and let the TV do the upscaling. Save some money that way.
