   @philpem Very cool! A proper video converter is something I am hunting for, but everything is absolutely huge for a desk install.

     This is what lurks under the Eldrich horror of cabling. A pair of fairly boring grey boxes with a pretty nice front panel.
     They talk to each other over a standard RJ45 straight cable strung between the RS485 ports, and the video is chained with a normal DVI-I monitor cable.

     Aside from broadcasting, these were also popular for shop CCTV systems - those would have had a composite output, connected to a VCR. These days you'd use a digital video recorder.

     Showing off a little bit perhaps... but the video stream in the first screenshot is being captured by a Datapath VisionRGB E2S video capture card sat in an old Dell R210ii server. The video stream is being converted into h.264 4:2:2 Baseline by FFMPEG, and barfed into a Multicast transport stream I can pick off with VLC, FFPLAY or OBS.
     It's pretty cool - the card has two inputs and can stream both, live, in real time. Each can take a DVI, VGA or Component (YPbPr) input.
