Okay so I bought the sony 1251 projector

if i buy the IFB-12 card
it will work with component and will be HD
so i wont need any wierd adapter or box to convert
the signal to component to vga?

no

yes

well youll have to buy 3 rca-bnc adapters.

Are you sure that card works as a component in aswell (YPbPr)?
Somehow i don't think it does.
RBG is not the same a Component.

Yes, you have to setup the jumpers properly though. If you do a search in the forum archives, there is some information on doing what you ask.

NO. The IFB 12 connected to the 12xx sets is only good to 480p....... at 720p or 1080i(as high as the projector can resolve), they cause serious green push.. they will display, if you like a dark-greenish image:(


For component-HD you will need a Component to RGBHV transcoder.

This is correct.

If you search the archives and look back at the original documents, you will see that the big advantage of Brian Hampton's "discovery" was that the card could be configured for "progressive scan" DVD's, which were the new hot thing at the time. But they were still only 480p. Somehow over the years, this has become interpreted as "progressive scan = High Definition".

Many people have wasted a lot of time trying to get this card to present a decent image from more modern HD video sources.

My 2 cents

I've run 1080i into them no problem.

I can't believe that I am disagreeing with Curt, but...

I have had several 12xx units and none of them would consistently work at anything above 480p when using a IFB-12 (not the -12a) in component input mode. I understand the G models would work OK with the -12 and -12a cards, however, but I have no first hand knowledge on those units.

Perhaps it is the variations in source signals, or perhaps I wasn't holding my mouth right, or the difference between the -12 and the -12a, but I never got a 12xx to work right at 1080i, or 720p with this card (the -12). Get a Moome card, or an HD Fury, or a Crescendo, use 1080i, and all will be right with the world. If you use a PC, I always found that the image looked best at less than 720p, say aroung 800 x 600 or so. Too many lines into a typical used 12xx unit and the image gets soft fast. Although a brand new set of tubes might do better, that just isn't likely to be anyones case anymore on these units.

So, will the -12 card in a 12xx accept HD (720p, 1080i, 1080p)? No - not when I tried it. Will it run 480p? Yes, but that isn't HD.

Hmm, the last -12 card I had was about 2 years ago, I can't remember if it was a plain -12 or -12a.

I do know what with the custom jumper settings (not covered in the -12 manual), it did work with my HD box.

I never deviated from the manual. If I had been a deviant, like Curt, maybe I could have made it work. Just kidding, of course - we love ya Curt.

I just noticed that Curt posted the setup for this card in his advanced procedures on his site. Try that out and it just might work!

For the life of me I can't find it on Curt's site. It's probably related to the fact that I got only a few hours of sleep last night. Can you link me?

Its right there at the bottom of the page where the manuals are.

I remember reading that the ifb12 had to be in slot A, and the projector had to be turned on before the source.

Is this true curt?

Ah, ok. I was looking for it under the advanced procedures link.

Thank you.

I think I have an IFB12 here, I'll check. I happen to have a 1252 set up on the bench, with an HD DVD player standing by. I'll post again if indeed I do have a card here.

Cool:) Curt, if you in fact do and get it to work, I'd like to know also. I have an IFB-12 and 12a here for my machines.

I have a IFB-12A, and it does component. I have not tried anything over 480 with it because the HDFury works so well. I suppose I could hook up the component out from the HD-A2 and see if it works.

hmmmm, what is this IFB-12? Is this something we already have on our projector or is it something we have to buy separately? Interesting. :)

I verified my 3 cards and all are IFB-II. Let me know guys so I can test it as well.

Looks like mine won't work. I just notice guys that yours is -12 or -12A and mine is IFB-11. Anyone willing to sell his extra 12 or 12A if it does indeed work on 1080i?

It looks a lot like the IFB-11 card in your pj. It has five bnc connectors, stereo audio connectors AND quite a few switches and jumpers on the board that allow it to be set to do composite, component, s-video, all of the different rgb types, both input and output. (As I understand it) The documentation I have is barely readable and I have spent a lot of time decifering it.:)

I read a post recently and they said that IFB-11 will not do component. :( I'm so sad. http://www.avsforum.com/avs-vb/showthread.php?p=13193990

Yeah... I have four or five IFB-11's here... and one IFB-12A. I'm not actually using it yet but it might come in handy if I ever get around to doing my stack. I'm using two IFB-11's in the 1272 right now, one for the fury and one for the vga from the pc.

I have 3 IFB-11 cards too. Previously, the two 11s on my 1272 are used up by HTPC and HDDVD. Until last night, only 1 is connected to the 1272. Feed is coming from Autopatch 1YDM where it has the connections from HDDVD and HTPC. I just send BCS command to the Autopatch via serial connection from HTPC. Command I execute in linux htpc is echo CI1O1T > /dev/ttyS1 if I want to watch from HDDVD and echo CI2O1T > /dev/ttyS1 if I want to watch from MythTV.

If I had the 12A, I was planning to put my Comcast DCT6200 set top box via component(YPbPr) connection.

I'm going to go with all digital inputs. I'm getting a HDMI switch that will accept four inputs and has two outputs so I can have multiple ways of sending signals either out to the hdfury or to a flat panel display in another room. I think the IFB-12A can be used to send the signal out of one pj into an IFB-11 in another at the same time, allowing them to be synced for a stack

That's what my Autopatch is capable of doing. It can send to 4 rooms simulatenously from the HDDVD source or HTPC. Or send HDDVD feed to 3 rooms and 1 room using HTPC source, or any video matrix. However, I also need an HDMI switch like what you mentioned. This switch will be useful once I get a BluRay player. This way, I can switch between HDDVD or Bluray.

The Autopatch sounds like a good unit for you. I put the LG bluray/hddvd combo drive in my pc so It would be able to play anything. Now hddvd is going down and I won't need it.:(
