Game Show: Vem Vet Mest?

Almost all of SVT’s broadcasts have at least some graphics played out by CasparCG in them.
This case is just one of many examples of a project that makes heavier use of CasparCG.

 

Over 9,000 contestants have so far have tried their luck at the popular game show Vem Vet Mest? in the eight seasons that have been shot so far. With a hectic shooting schedule of five 27 minute shows recorded per day, having a easy-to-contol system was key.

The show format dictated an intricate scoring system involving light bulbs and fast-paced questions visible not only to the viewer at home, but also on large screens in the studio (including special judge/host screens with both questions and answers.) Using the modularity and openness of CasparCG, we were able to interface not only with both physical buttons, lights, screens and dimmer packs; but also deliver keyed broadcast graphics and audio cues directly to the vision mixer.

Everything was controlled from a single laptop running custom-built controller software that interfaced with all CasparCG play-out servers, the database with questions, the judges’ buttons, the light bulbs and all the 15 contestant stands with buttons and screens.
