Behind the scenes on most any large entertainment production today - from an arena spectacle to a theme park dark ride, from a concert tour to a Broadway stage - you will find Ethernet switches, cat 5 cables, and IP addresses all playing a critical role carrying a variety of control protocols that make these sophisticated shows possible. In this talk, John Huntington, author of Show Networks and Control Systems, will give an overview of the ways that networks are used on shows, and why and how we use equipment from traditional IT applications. In addition, applications from real shows will be featured, including a detailed exploration of the sophisticated control network for the Gravesend Inn haunted attraction.
