How do you get 74 Samsung devices all playing different videos synchronized at exactly the right time? You call Aaron and myself from the RGA Prototype Studio. We built a node.js/socket.io/Android platform to allow the director to start/stop/reset the videos on all the devices simultaneously. The devices were all Wi-Fi’ed into a heavy duty router and there was a Samsung laptop running the node server. The director had a slick web-based management console to run the whole thing. The system took 4 days or so to build and it ended up working great. The RGA Content Studio and RGA Samsung team put the whole thing together and it came out amazing. Take a look:
