JVC HD1 + CIH + Lumagen HDP success?

[DuyK]

Hi all,

I thought I will post this Q outside of the main JVC HD1 thread as it is now very large.

Is anyone having good results with the above combo - would really appreciate your impressions. I have a HD1 on order and was looking into a Lumagen HDP to do the vertical stretch for a scope screen setup and to clean up the SD signal from cable TV.

Also, how does the HDP scaling and deinterlacing performance compare with the Gennum chip on the JVC HD1?

Cheers,

I can't comment on the vertical stretch aspect of your question, but the HD1 overscans digital SD sources by 2.5% all round (5% in total both horizontally and vertically). That tipped the balance for me into going the scaler route again (Radiance as it happens).

There is also the current firmware issue of HDMI 480/576i signal being completely messed up and a chroma issue with 480/576p YCbCr 4:2:2 signals.

Thanks Viruskiller. Very jealous of your Radiance

Anyone with a the HD1 and + HDP who could confirm the vertical stretch ability

Cheers,

I think there are hardly any CH systems in UK. If you go to AVS forum I'm sure you'll find plenty of folk with CH systems and Lumagen. I have a client in UK who uses an HDP Pro with an ISCO3 and a PD Cineo3 1080P DLP and has excellent results. (He used a 12" CRT projetor previously and money was not an object in the sourcing of components for his system)

Ah yes. The same client who pushed me off the HD fence by buying me a Tosh XA1. He's cost me a lot of money you know! You can thank him, in part, for another Radiance sale...

Aha...so you were one of the lucky ones from Hitchikers...I heard about that. His system is without doubt the most amazing Home Theater room I've been involved with. Truelly awesome.

I'm on Hitchers far too much, so perhaps luck had nothing to do with the fact that I saw his offer first. I've seen the photo over on AVS. Even the Yanks think it's awwwwsome.

Getting back on topic, how are different cinemascope aspect ratios handled in a CH system. I mean you can have 2.35:1, 2.40:1, 2.42:1, etc. Do you set it up for 2.35:1 and live with much smaller horizonal bars for the even wider formats? Presumably the lenses only cope with giving you a 2.35:1 image from a 16:9 panel?

[Gordon @ Convergent AV]

That's a question for someone with such a system. I would say that it would seem to me that for anything that isn't 2.35:1 you will get black bars at top or sides unless you zoom or distort image

I set mine for 2.35:1, and leave it. I can't say that I've ever noticed the difference in other ratios other than 16:9 of course, but if you can zoom the image to crop the sides slightly of wider than scope formats, that may be an option. So far I've not felt the need to do that.

Hi,

I've just moved from using a Ruby with a 7 ft wide CIH screen (using the zoom of the Ruby to go from 1.78 to 2.35), to a proper anamorphic lens based system, (using a Lumagen HDQ for scaling). The lens is a Prismasonic FE1500R.

Things are looking really promising so far, although I have not finished setting it all up yet (need to make a more permanent mount for the lens for one thing).

The biggest improvement has been on SD DVD, but HD DVD has also benefited, and now I don't have to zoom, lens shift, and refocus every time I change format

I can certainly recommend going for a CIH setup – way more cinematic – its a just a bit expensive to get into (I could never justify the price of an ISCO III, for example).

As for the black bars at the sides - I use velvet curtains, the lens also has a handy side effect of blocking most the light overspill I had when just zooming the projector, so its easier to get a tidy edge to the image anyway.

I plan on leaving it at 2.35:1 and manually mask the vertical bars for 16:9 material (which is only a small % of my viewing material).

Thanks for all the comments - will check out the US forums.
