Hi, I was looking at a cheap and convenient way to carry audio and video signals over long distance (around 20m, 66ft). I stumbled over these: http://www.svideo.com/svideobalun.html http://www.kvms.com/nav/item.asp?item=8560 http://www.hometech.com/video/videopwr.html http://www.videocapturecard.com/svideobalun2.html etc... They are baluns, that basically allow a CAT5 cable (110 Ohm) to act as a cable of another impedance (75 ohm in svideo case). It is very cheap given the price of CAT5 these days... Not mentionning my house is already wired with CAT5, hence my need. I would need to carry three signals over a single CAT5e cable (4 twisted pairs): SVideo SPDIF and USB, so I need to build one of my own (unless someone knows of such a balun) Where could I find resources over this ?
