S-Video problem with External Connection
Posted on 2006-04-13
This is probably more an A/V question but I'll start here. If there is somewhere more appropriate, please direct me. here goes.
I manage the IT for a client that also has a conference room w/ 4 Epson projectors in the ceiling, with Wireless B cards. I can connect a laptop to any or all of the four projectors using the Epson MP Software. No problem. But there's a wireless lag, naturally, and there's now way anything other than some sort of random picture slide show can be run on all four projectors via powerpoint. A One to one connection wirelessly is OK, but there's still a lag (and Epson says they do not support Wireless G in these units, by the way. Only B).
But there is also the ability to play DVD's on these projectors, in one of two ways:
1. There is a DVD Player and Amp on a rack in the equipment room which can have it's output channelled to any 1, 2, 3, or all 4. Picture a room with the same movie playing on 4 screens all around the room. Fine.
2. A Portable DVD player can also be used in the room from one of three different hook ups along the outside perimeter of the room. In these three areas, there are two cables coming out of the room. Video and Audio. These are hooked up to the DVD and the same thing that can happen in 1 above can happen here. Picture the same as in 1, but controlled locally from within the room rather than back on the rack. Same ability to direct output to 1,2,3,4 projectors. Fine.
Here's where I need some help. I anm pretty network savvy, but really a/v challenged.
The client complains any time they try to use the Epson software to capture computer (Powerpoint,etc . . .) because of the wireless lag. More complaining if they try to direct to more than one projector.
Don't I have all the "plumming" I need to channel a laptop S-Video from the laptop, thru the video hardwire (and running audio from laptop speakerphone jack)?
There are a number of Dell laptops that have S-Video Out. There are also Dell TV/Digital Audio Adapter Cables. That has
S-video to Computer <-----I----------------->Composite Video Connector
I----------------->S/PDIF Digital Audio Connector
Shouldn't I be able to plug the S-Video adapter into the computer, hook the composite video connector on this adapter to the video cable coming out of the wall at different spots around the room, and the get output to 1,2,3,4 projectors and control the same way as I can in 1 or 2 above? I'm sure I'm missing something major. But like I said, I'm A/V challenged <g>
Anyone want to have a go at it here?
