Title: Light gun to work w/component?
Post by: picasso on July 25, 2005, 02:22:39 pm
Is there one???

Do mean Component YPbPr or composite?  The Act-Lab TV-Out guns work for composite video if that is what you meant.  As for Component RGB style video I have no clue.

I meant YpbPr.   I am using a dongle off of my ATI card to component input on a Toshiba 27" TV.   I have heard the light guns do not work with this setup but did not know if that was true or not.

Do you also have svideo or RCA out?  If so I think you just need to hook the gun up to that.  it jus tneeds something to sync with, right gun experts?

I don't know the situation on the ActLabs, but I know a Playstation's GunCon just watches for the sync.
And can be hooked up in line with the "green" line in component video.

OK so for a non-technical guy what would I have to do?   Splice some wires?   I have s-video on the television as well but I prefer the component picture.   Could I just plug the gun into the s-video port and it would work with my component video?

The first thing I'd try is feeding it the green component video line just as if it was a composite signal.

If I'm right about how they work, that'll do it.

Some kind of RGB connection uses the so called "sync on green". So if you don't have any separate sync signal you should feed the green component in the gun's composite input.

OK... I will give that a shot and report back.   Thanks..

Doesn't that dongle have composite video out too?

I think the point is for those of us using a component connection for better picture quality, it would be considerably noticeable to go from component to composite.

With that said, I was never able to get my Act Lab TV gun to work with the s-video connection (the only way to hook it up I believe) on my Toshiba TV.  It did work on my old TV that didn't have component (but the picture quality was much better with component, so I sacrificed the few gun games I'd play, for picture quality)  I did try the Guncon2 option, connecting the composite cable to the green component input.  The gun was recognized, however I was never able to get it to stop the gitters.  After attempting suggestions (with unsuccessful results) made on the Guncon thread, I needed to give it up for a while.  The concept is there, and driver seems okay...the gun just wouldn't stop gittering.

Oh well, at least you know you can hook up a composite cable into your green component input. :-\

Wait scoobie ... are you talking a bout a standard RGB scart cable ? If so,  did you try to feed your gun with pins 19 / 17 for SYNC / GROUND ?

Maybe you should put some pictures. It already sounds strange to me that you have a videocard with TV-OUT that outputs an RGB signal ... generally it is composite or S-VIDEO ...

If it helps, I have been running the Pelican Silent Scope Rifle through the component output of my Xbox on my widescreen TV (rear projection no less) without any picture or functional degredation.

I'll try to take some pics and post soon.  Thanks.

Here is my setup using component inputs using an ATI Dongle.

I think that people are confusing RGB inputs and component inputs which are NOT the same thing.  In North America (can't speak for elsewhere) a component input (as stated above by Testicle) is YPbPr or more commonly referred to as YCbCr.  These inputs carry the Luma ("luminance") and Chroma signals.  See Wikipedia herehttp://en.wikipedia.org/wiki/YCbCr  People are often confused because the typical colours of the RCA jacks used for component inputs are red, green and blue.

RGB inputs on the other hand typically require more than three connections to carry the vertical and horizontal sync etc.  Sometimes a composite sync signal can also be carried on "Green". 

When you hook up your composite cable to the "Green" RCA jack of a component input you are actually hooking up (I think but can't confirm) to the Luma input.

As far as the SCART standard, I have no idea, but I believe that it is a type of true RGB input.  Component inputs can be considered "inferior" to true RGB inputs.

Hope this helps.

Yah. And luma carries the sync signal.
I can't guess why the gun is jittering, unless it just doesn't like what its "seeing."

SCART's a catch-all connector. It DOES carry a 4-line RGBSync signal.
And composite video, chroma/luma, and stereo audio.
