This might not be the best place to ask, but I might as well give it a shot. I posted it on a couple more technical forums, but might as well copy/paste here as well.
My church runs a service in one room, and we broadcast it live into the other room where we show it through a projector. We run two dv cameras (720x480i 4:3 dv) and a computer (ppt slides) into a mixer, then run the line from the mixer into the other room for projection. This works fine, but it is incredibly difficult for us to time the two room's services together (one is usually running too slow or too fast), so if we could have a 10-20 minute broadcast delay, sort of like a dvr, that would be fantastic.
Can this be done with a computer, by capturing the dv line from the mixer directly to disk and then beginning playback of the recorded content on the projector with, say, a 15 minute delay? What if I use a conventional capture card and capture it as S-Video to mpeg2? We're on a budget, so we can't afford investing thousands of dollars into it, so a cheap solution would be great.
Any ideas anyone?
