No special setup is required for web broadcasting except that the

video capture workstation must be able to connect to the Internet.

The video capture workstation can be connected directly to the

Internet or to a LAN that is connected to the Internet.
The following procedure is the same whether or not Epiphan has

permanently enabled web broadcasting for your Frame Grabber.

To start a web broadcasting session

Start the VGA2Ethernet user interface.
