I'm wondering if anyone knows about a product that will flip an image horizontally, like a mirror mode. I'm looking to take a component or composite input and flip the signal horizontally, so I get out the mirror image of it.

Aurora Multimedia makes one, but it's overkill for what I want and expensive.

Any advice would be appreciated!

Thanks!

Are you using a projector? Most have a mirror mode.

Nope, no projector here.

It's actually the output of one of my arcade boards. The video comes out mirrored due to the way the original cabinet was set up and I'm trying to find a device or a schematic for a way to swap the picture around.

You can rewire the H yoke windings on a direct view CRT TV, that will flip the image. That's not applicable for any digital set though.

Yeah this would most likely be for a digital set and I don't want the change to be permanent either.
I was hoping for a circuit I could build or a not so crazy expensive device to do what I want. I'd be fine if it only support a composite input.

It seems like it'd be easy to do, but I don't know enough about how TV's work.

Nope. not that easy at all, sorry!

OK, a couple more posts came in while I was typing. Digital how? Is it CRT based?

An LCD monitor, I don't want to modify the monitor at all. I'm just looking for an external device to do this.

I want to take the composite or s-video output from my board, plug it into something, then run it into the TV.

Not gonna happen, sorry.. Smile

If I had a spare 3 grand laying around it'd be happening, lol.

Guess there's no market for this kind of thing. At least in the consumer world.

Go CRT it's so much easier, better looking too.

Here's the device: http://auroramultimedia.com/?section=products&id=2
For me all I care about is the ability to flip the screen horizontally, but the ability to take two inputs and output them as a single video is cool too. They also have a pro model that can handle 4 inputs.

I think they can also scale and do all that fun stuff too

This is really simple - use a PC. A $300 machine or some old hacker box with a video input card running a copy of MPlayerClassic to the TV Out would be perfect. Then you could also do whatever gamma correction, color processing, etc, you needed. Or it sounds like you could just run it straight to the VGA output, based on what you're doing.

Dirt cheap, simple, and can do more if you want.

whats the application? maybe we could make a better suggestion.
a mirror works but probably cannot be applied to most applications. depends what you want to do.

I'm converting an X-men arcade board to work on my TV. The board outputs RGB and composite sync. I already have a device to convert that to NTSC type signals. It was a 2 monitor arcade machine. The left hand monitor sat down in the cabinet and was reflected up to sort of hide the edge between it and the right hand monitor which sat in the cabinet normally. So the original machine did use a mirror to flip around picture.

I didn't know MPC could open devices, so I tried that! But the picture is very very dark on my monitor. I supposed that'd just take some tweaking to fix that. I didn't try to run it through the TV Out though.

Actually the MPC picture isn't just dark it's really distorted. I'm not sure it knows how to take the s-video input from the capture card.
Vdub works fine. I might have to google around to see how that works. I've never had luck using VLC to open my capture card either.

Ah, now we are talking. I've worked with arcade game boards quite a lot.
I would bet that the arcade game has a configuration setting or dip switches to flip the video for you.

If that doesn't work, I'd recommend emulating the game with MAME. you can do that legally if you own the real board.

Yeah there's no dips or menu items to flip the screen on the 6 player version of the board. Oddly enough the 4 player version has an option to flip the screen. Yeah MAME is an option, but it'd be cool to get the real thing running. And it's something about the satisfaction of completing the project and actually getting the thing working. Half the fun is getting there!

I may have found a slightly cheaper solution to my problem.

Their down converters and scalers appear to have the mirror option. Plus they're "only" in the $700 range Razz

It's like a bargain compared to 3K!
