Video mixing chess games on tv in Norway using Ethernet Shield

When The Norwegian Broadcasting (NRK) planned the television broadcast of the Chess Olympiad 2014 in Tromsø, Norway, they encountered a challenge: how to mix video, graphics and the results of many ongoing chess games simultaneously, requiring 16 cameras for the games going on at the same time?

On their blog you can find a long and nice post about how they found the solution using Arduino Uno, Arduino Ethernet Shield and the library for Arduino to control such Atem switchers written by Kasper Skårhøj:

At first, the idea was to use a computer with a webcam for each of the 16 games, then mix video images, background animation and results in software on each of them.

Afterwards the finished mix of images would be streamed to separate channels in our web player, so that the online audience would be able to choose which game they wanted to follow. This solution would also provide our outside broadcasting van (OB van) with 16 finished video sources composed of video, graphics and results. This would make the complex job of mixing all video signals much easier.

After thorough thinking we came to the conclusion that for our web-audience, it would be better to skip the stream of individual games, and spend our resources on building websites that could present all games in the championship via HTML in real time. This would also give the audience the opportunity to scroll back and forth in the moves and recall all the previous games in the championship. We started working on it immediately, and you can find the result on our website nrk.no/sjakk.
