Video Assist Centre
Right from the start, the DFL and the German Football Association (DFB) opted for a central workplace for video assistants at the Video Assist Centre (VAC) in Cologne rather than trucks at each individual stadium. The VAC has supported the referees on the field in all 306 Bundesliga matches since the 2017-18 season and was extended to Bundesliga 2 from the 2019-20 season. The two-year test and training phase for video assistants already took place at the facility at the Cologne Broadcasting Center (CBC).
Each video assistant at the VAC is supported by operators. All the camera images from the stadiums are available so that contentious situations on the field of play can be assessed optimally. Technical implementation is performed in conjunction with Hawk-Eye, the company that is also known for the introduction of goal-line technology in the Bundesliga in the 2015-16 season.
