What's up with the JVC 34" 16:9 that has a resolution of 1500i? It's the only HDTV that I've seen with this feature. Is this a good HDTV?

HD is 720P or 1080i. 1500i is therefore meaningless. Do you have a link that states this or shows it or has a description?

I have the JVC -AV34WP84 and I think it is a awesome TV, esp for the money. I dont know much about the New D.I.S.T. 1500i-- the industry's highest resolution scaling technology at 1500i that JVC states. There's not alot of info on this TV(reviews and such). I have no regrets in getting this TV. It has super clear/detailed PQ while showing true HD programing. Color is great also.

Here's a press release, 57:

Thanks for the link. Neat. I'll have to read more about this and see if anyone copies it.

Some of the new Hitachis convert incoming SD to 1080P for manipulation, but then the final display is 1080i.

This seems to intimate that the final display is 1500i, although that isn't totally clear...

Since the previous link was from 2002, I found the following from a Canadian Site.

Sorry, but I have to interject a bit of sanity (technical knowledge) to this discussion.

The link provided by BadCamper is chock-full of a whole lot of "techno-babble" and totally misleading "information" regarding this 1500i business. JVC ought to be ashamed of themselves! I have no doubt whatsoever that this set is capable of stunning picture quality ... that's not what I'm qustioning at all. What I do find distressing are claims such as "10.7 million pixels" being displayed which is complete nonsense and misleading to the max! HDTV has a maximum capability of a little more than 2 million pixels (2,073,600 to be exact) and there's no possible way to INCREASE that number by more than 5 times. It's a physical impossibility.

The absolute clincher in my book that would steer me as far away from buying this set (if I were indeed considering it) is the fact that there's only a ONE year warranty on the CRT. This fact alone is enough to be a "deal-breaker" for it exposes you to become the disgusted owner of a VERY expensive door-stop should the tube fail after the 1 year warranty has expired.

Just what JVC had in mind to even consider designing the circuitry involved in scaling all incoming signals to an un-mathematical 1500 scanning line display completely escapes me ... it makes no sense whatever!

Here's the link re: JVC'S 34" 16:9 HDTV w/1500i, it's of their website. I believe you, but why would they make such a claim?

www.jvc.co.uk/article.php?id=100209 More detailed info on D.I.S.T. down in middle of page. Can anyone explain this Technology?

All HDTVs perform upconversion of 480i signals. They do it to either 480P, 540P or 1080i as the display mode, or 720-788P if you've got a fixed pixel display HDTV.

This JVC TV apparently upconverts to 1500i, which may provide a clearer picture if done well. What I don't like is that they apparently deinterlace and reinterlace, which can cause problems since I find that upconverting from 480i to 1080i provides one of the better pictures.

If the original signal is 480P or 720P, these signals obviously don't get deinterlaced, they only get interlaced for the final display.

As mentioned earlier, Hitachi have an upconversion circuitry in their newer TVs that upconvert signals to 1080P before processing, perform all processing and then display at 1080i (which obviously also involves deinterlacing and reinterlacing).

It also, from my brief read-through, performs the appropriate 2:3 pulldown (which is done at different cycles in the UK)

I suppose these are "differentiation gimmicks" to some extent. The proof, as they say is always in the viewing...

I agree! To clarify things, I didn't provide the link, I just did the Googleling and dug it up! I haven't seen this product in action, and am not a terribly big fan of JVC to begin with.

Is JVC opening themselves up to lawsuits by falsely claiming to have 1500i technology.
