A paper exploring a “distributed digital signage system” by Justin Lloyd

In this lengthy paper I investigate and document the creation of a portable digital signage system for conferences that can be controlled over WiFi from a central server. The distributed digital signage system provides a robust communications system that handles failures gracefully, ad hoc updates to time locked and time sensitive, structured content, and the ability for each digital signage to build an impromptu mesh network with other recognised digital signage in case signs are moved out of range of the WiFi base station.

Each digital sign is controlled by a microcontroller with high-resolution graphics output capable of displaying video, formatted text messages, and simple animations.
