In its updated guidelines, the German Football Association (DFB) provides an extensive set of recommendations for using state-of-the-art video technology in stadiums. These have been drawn up with assistance from the Electro and Digital Industry Association (ZVEI). The new version of the practical guide, which was first published in 2013, takes account of technological progress and the latest developments concerning the legal framework. The guide was a collaboration between the Video Systems expert group at the ZVEI and Christian Delp and Gerhard Kißlinger, both of whom are the Stadium Officers at the DFB. One of the key reasons why the guidelines were revised was because of the EU General Data Protection Regulation (GDPR), which came into force in 2018. GIT SECURITY spoke to Fabian Stegmaier, Manager Safety & Security Technologies at ZVEI and Christian Delp, DFB Stadium Officer.
