Feeding Video to Portsdown from vMix

You can stream video from vMix from a Windows PC and then transmit it using the Portsdown transmitter. This works with the either the Portsdown filter-modulator board or DATV Express.

Use with the Portsdown Filter-Modulator Board (IQ Output)

Here is the system block diagram

First install vMix on your PC and make sure that it works with your selected video source. vMix can be downloaded from here: http://www.vmix.com/ The free version handles SD video and is adequate for our needs.

The next step is to install ffmpeg on your PC

Make sure that your PC with vMix and your Portsdown transmitter are on the same wired network. Wireless networks might work but have not been tested.
