I have several times pointed to interesting material that is posted to Control Geek blog. Here is another good time to point you there. My Show Networks talk from The Eleventh HOPE (Hackers On Planet Earth) article tells that John Huntington’s Show Networks talk from The Eleventh HOPE (Hackers On Planet Earth) is now here on Youtube.
The talk gives a good overview of the current state of the live show control technology like light control, audio, video etc. Today those high tech devices are very often networked to Ethernet network that is intentionally kept separated from Internet. The talk tells how this show technology industry works and what specific demands to technology it has. It’s about 50 minutes long and worth to watch if you have anything to do with show control systems or interested how they work.
