I have seen the current crop of D-ILA TV's in stores like BB and Sears and I think they look amazing. I'd really like to hold out for something with a native 1080p resolution though. Has anyone heard anything regarding if there are any plans from JVC to release a 1080p capable D-ILA RP set in 2005? Thanks in advance.

JVC has a $30K front projector that is 1080p. It uses Dila chips, so they have this chip ready, just not in a TV at the moment. I would guess it might get announced at the january trade shows. But since they cancelled the 61 inch dila with DCR, I am not so sure they are looking to support Dila for very much longer. Dila is a lot like LCOS, Intel and Philips got out of LCOS this year, perhaps that is going to happen with JVC as well.

I'll be at CES 2005 so I guess I'll just have to wait to see if they have a 1080p capable RP set on display. I was already aware of the Front Projector HD2K. I guess it is a good sign they already have a 1080p capable chip.
The only thing about that is JVC uses digital D-ILA chips in their front projectors and analog D-ILA chips in their rear projection sets, so it's not really the same chips (this generation anyway).
Thanks for the info anyway. Hopefully I'll have my questions answered at CES.

The high definition standard does not contain a specification for 1080p, so it will be a very long time before any television program is broadcast that way.

I stand corrected.
Still, it will probably be years before any television program is broadcast in 1080p, as well as a TV that can support 1080p for a reasonable (less than $5000) price.
I agree Broadcast TV wont be 1080p for a while but HD-DVD will be 1080p, and the benefits of having a TV that upconverts 1080i to 1080p will be great.
Just remember the difference 480i to 480p made...

Where did you read that HD-DVD will be 1080p? And wouldn't you rather have a TV that does native 1080p instead of upconverting an interlaced signal (i.e. trying to create something from nothing)?

1080p DVD is very likely since there are no bandwidth issues.
And yes I would rather have a TV that has a native 1080p Resolution, that was exactly what I said in my post prior to yours. If the TV is 1080p and cable is 1080i. The TV will scale the picture to it's native res resulting in a nicer picture.

I beleive Sony is working on a 1080p set right?

I was at CES this year and spoke with representatives from the HD-DVD camp as well as Blu-Ray and both parties said their respective formats are only slated for 1080i playback (meaning NOT 1080p). I hope this clears up that debate.
As far as TV's. Samsung is set to release quite a few 1080p models around June that are around the $5000 mark mentioned. In fact, they should have one this month (February) but better models are slated for June.
To keep on with the JVC theme of this thread, I did see the 70" HD-ILA TV and it looked nice but the loop they were playing on it was filled with motion artifacts. There was no way for me to determine if this was caused by the pre production set or the quality of the signal being fed to it.

You do it with DVD's. Why not deinterlace 1080i to 1080p?

As for upconverting, you appear to be right. I had previously (incorrectly) understood that interlacing only shows half the picture each frame, but it actually shows the entire picture each frame by drawing every other line twice per frame. This means the only advantage of a 1080p TV would be upconverting from 1080i.
I can't see any other advantages because:
a) We know TV won't be broadcasting 1080p for a long long time
b) We know HD-DVDs and HD-DVD players will not do 1080p
The 1080i -> 1080p upconversion advantage also depends on HD-DVD and HDTV content being in 1080i and not 720p, which is not certain at this point.

Why?
Are you saying you can't upconvert 720p to 1080p?

Personally, it seems like the less converting the better, no matter the starting resolution. except for making an interlaced signal into progressive, any signal converting is just that: fake HD.
It seems like most broadcast HD is 720p, and will be for a while to come. With Dish and DirectTv doing downrezzing and overcompression, 1080p sets are pretty well useless at this time. I am dismayed that blueray and HDDVD are only planning 1080i/720p, but that is the breaks, few people have the capability, so why would they spend the money on the tech.
I would like a 1080p display, but that is years down the road when my current tv breaks beyond repair. and by then there will be something better on it's way...

...any signal converting is just that: fake HD.
Many TV's/STB's comvert 720p or 1080i to various resolutions. It's still HD. Granted, the less manipulation, the better.

Most broadcast HD is 1080i. Only ABC, FOX and ESPN-HD are 720p.

UPN and WB are 1080i? I know the cable companies usually forget them, but I thought they were using 720p?
less manipulation is better, that is what I should have written. compress/convert/uncompress just isn't the best situation.

Max -- I am considering buying the Sony XS -- are you happy with it, any issues?
Yes I am very happy with this TV! The PQ on HD is jaw dropping, DVD's look great, Xbox is awesome but SD could look better.
Overall I could not be happier with it, and I would buy it again if this one broke...

Any idea what contrast ratio we can expect on the new 720p models or the fall 1080p models? I'm interested to see how they stack up in terms of the DLP models shown at CES 2k5. Also, do you know what the pixel response time for the new 720p or 1080p models are supposed to be? Sonys SXRD model (Qualia 006) has a stated response time of 5ms, I'm interested to see how the new JVC line stacks up against that. Thanks in advance for any info you can provide.
