Jitter and Wireless Networks

Hey all,

I’m brand new to jitter. I have been reading up on it and feel that it is suitable for my group masters thesis project. However, I know this seems like a silly question but how does Jitter transmit data to a projector?Does it need to be directly connected to a projector through a computer running jitter or could it be streamed over a wireless network?

We hope to use Jitter to manipulate data and send different videos to four different screens.
Does this require four laptops each running a copy of Jitter and attached through cable to the projector or is there anyway to use one laptop and one copy of jitter to output to multiple screens?

Apologies if this has been already asked but I couldn’t find an answer while looking through forum and I need to know this asap.

I think your computer would require a quad head video card. I’ve only ever worked with a matrox triple head2go.

I just need to know does it require four seperate versions of jitter to do this as we have no budget provided by the college so buying equipment of that price is not feasible for us.
Thanks for the help,

you can use the runtime version on any computer indefinitely for free.

Are you referring to the downloads which stop fully functioning after ten minutes?

Thanks for your response!

I’m curious where did you find such a download?

I have one max runtime running for almost a year now.

And demo versions lasts for 30 days.

There’s absolutely no time limit for running Max/MSP Jitter patches through the Max Runtime.

Regarding your original questions(which are by the way already asked&answered on the forum numerous times):

* Computer usually sends data to the projector the same way it sends it to your computer screen. Usually it’s a VGA or composite output. It has very little to do with Jitter.

* The number of video outputs depends on your hardware setup, not on Jitter.

* Jitter can stream data through network (jit.net.send or jit.broadcast). Wireless network is less optimal for this than perfectly configured ‘cabled’ network.

There are a lot of possibilities, and the correct choices depend entirely on what do you want to achieve.
Imagine a situation where you have 4×4 windows where you want to have different videos running. Usual solution would be to use 16 projectors and a bunch of computers. But instead of using sixteen projectors, it might be possible to use one projector outside the building and just mask the space between the windows).

Please think before you post.

Good luck,

in regards to Nesa’s last post, search “keystone” in the forums. there are many examples of advanced keystoning, and this technique can be used to create multi-channel video installations with one projector. I do it all the time.
