Question

Stitiching Multiple Video Feeds Into One Large Feed

Mar 11, 2013 2:40AM PDT

I am looking for a (hopefully relatively cheap) way to stitch together multiple video feeds into one. Specifically I need to set up 3 projectors side-by-side and be able to switch between sending 3 different feeds and sending one large feed across all 3. Is there any way to do this with just software? I know that for a proper set up I should have edge-blending projectors, but I don't, so I'm pretty much looking for a good way to fake it if possible. Also is this something I can send from one source (preferably a computer) or will I need multiple sources for the multiple feeds?

No.

Said feeds are not shared here so I have to guess that this is the usual where you need some matrix switch panel.

And to involve a computer means we have to have the digitizer for the source video (bucks there) and plenty of horsepower to do the video work in real time. This area is full of video processor boxes that run a few thousand each.

Why not prepare the show ahead of time and play it like others have in the past?

So, no hope?

My company is doing an event for a sports bar, and they want to be able to stream 3 different games on 3 projectors but also be able to switch them all over to one large image to display logos, ambient images, etc. I figured it would be something that couldn't really be done without special hardware but I thought it'd be worth the ask.

The hardware isn't as special as it once was.

But we are discussing in a vacuum here. Without knowing the source format we can't start or end the discussion.

For example, if the source is HDMI that means it has HDCP and can block many solutions that we used pre-HDMI.

If you google VIDEO WALL PROCESSORS then you find the usual solutions. I'll stop here since there is a vacuum.

Hardly a vacuum...

This is hardly a "vacuum" since you never asked what source signals were being sent. I was asking for a general answer to IF something like this is even possible. We also have a video wall processor with DVI and HDMI ins and outs, so let's run under the assumption that will be using one of those. Normally we run it through a graphics card into a CAT5 signal but that won't work for our projectors. Is there even a way to use the video processor for what I need? As far as I know it is a single signal output, so more of a beefed up video SWITCHER. If the answer is a flat out "no" without the right equipment then so be it. If you need more information all you need to do is ask, but please don't just assume no information will ever possibly come based on 2 general posts.

This is up to you to supply the details.

Look at the words in red when you post. Until the details are known I can't give you a good answer.

My background includes circuit design and software on DVRs so if you want to discuss this, that's OK but I won't be asking for much. As this is a discussion forum, you supply what you can. Most folk are unaware of the HDMI issues and my guess is the source is HDMI.

Up to you to tell what you can but as it stands it appears you want the type of service you get when you call a vendor. This is just a discussion forum so you can see how it's different.
