I work at a school where there is a closed circuit TV system. I think it's over COAX, or maybe it can be RCA.
Either way, I need audio.
I have a computer with HDMI output. This is the only way I can get video onto our system.
I need something like this"
> (HDMI to COAX modulator)
> Main TV Switch
Computer With Feed
> (HDMI to RCA converter)
> (RCA switch)
Unless someone wants to donate A LOT so we can buy HDMI TVs?
Maybe there's another way, but we need audio and video. It also needs to be as simple as possible.
