I wonder what's needed to transmit analog TV using a computer.
The requirements would be:
- Using a computer as source.
- Ability to share the full screen.
- Any PAL or NTSC Tuner.
Multi-channel transmission would also be nice, maybe using multiple desktops for different channels and multiple virtual audio cards for each channels audio.
Preferably a PCI-E Card one could just connect to an antenna cable but an SDI Graphics Card with some external "converter" would also be an acceptable solution.
I've found very little information on this on the web but while working at a computer store I once got my hands on a PCI card I think did just this for hotels
