Multiple Inputs Multiple Outputs

[ciscoraz]

Hi All,

Setup -

Inputs

Sky Box = Scart or S-Video
PC = VGA and/or S-Video

Outputs

Projector 1 = VGA and/or S-Video
Projector 2 = VGA and/or S-Video

I have currently only one projector setup that is connected to the PC via VGA and to the Sky box via S-Video, so swapping betwwen the two inputs is very simple (select computer or video on projector remote)

I am looking for a solution that is as simple as using the remote above (or a switch) that will enable me to set the two projectors to run either Sky or the PC, because of distances covered I have opted for a complete S-Video solution (good idea????). There are several solution on the market from Ocean, Kraner and Knox, but we are talking about seriouys bucks. SIma SVS-4D is relatively cheap has anyone had any experience of these? Or good someone suggest another solution.

Thanks for reading this post and any feedback/ideas given.

do you need to be able to send diffrent signals to each projector? (ie to be able to watch sky on 1 and pc on the other) - if so the sima box will not do it, you need a 2x2 matrix switch (more ????)

on the other hand if you are happy for the 2 projectors to allways show the same image then a simple video switch will do the job (you can get them a lot cheaper than the sima) - if you can't find one with 2 outputs you can make a simple passive spliting lead that will split the signal to the 2 projectors (an active VDA would be better - but is unnessasery, the sima switch uses a passive split)

as to using svideo - no this isn't a good idea, it is much more flakey and can't be sent over long cable runs without the use of line amps, stick to composite - you will hardly notice the diffrence in quality and swichers VDAs and wotnot are loads cheaper in composite than s

I'm not sure where you're getting that aversion to SVideo.

I try and keep everything running S, instead of composite, and I notice a pretty sizeable difference. I'm usually running several sources into a mixer, and then out to a single projector, however.
I think it really starts to show as you get more generations of color degredation with composite.

My advice is to spend some bucks on the cabling, and properly powered signal splitting. The difference is only percentually higher, but compared to the cost of the rest of your gear why cheap out on something that effects everything you'll see.

You can split a y/c signal into two bnc cables, if you're worried about using heavier shielded cables.

As far as I know, a composite signal shouldn't hold any better then S, S cables just tend to be more expensive... and perhaps flimsier then rugged BNCs.

Check out Trianglecables.com for cheap, long SVHS cables.

I've tried a few wireless solutions, and would love to share my input here.

I intially tried FM transmit/recvrs that work around the 900mhz range... bad idea. I still have them, if you want to buy them, they're all yours. they don't sent a video signal well at all, and they catch a lot of interference from loud speakers and amps.

They sell a 2.4 Ghz setup that does 3 signals, like video, right audio, left audio. They'll send video (or s-video) across all 3, which is good, they also have a 4 channel selector that you could change between. Check them out, i'm a big fan.

Sorry for the incoherent rambling, it's early/late.

Hi All,

Thanks for your advise.

A recent trip to Maplins and I located a Aver TV Box. I have connected the Sky box (S-Video) and the PC (VGA) to the Aver TV Box which then has a VGA out, this connects to my first projector that also has a VGA out, this then connects to my second projector.

It seems to work well, I will be installing the kit properly soon and will see how it stands up to a Weekend of partying.

As you can see from the above solution I only require to show either PC or Sky on each projector not both at same time.
