The implementation of the Video Assistant Referee (VAR) system in football was intended to help the pitch referee in difficult situations increase the objectivity of refereeing. Interaction and verbal communication between the pitch referee and the VAR is made via a specialized radio communication system. To ensure the decision-making transparency of controversial moments all communications between the VAR and the pitch referees must be recorded and logged.
Organizing a reliable and private communication channel on the field is quite a challenge. The Vokkero® intercom system has become the de facto standard for radio communications at sporting events. It ensures reliable voice communication by using digital, secure technology, compliant with the requirements for VAR in football. Another advantage of this communication system (the Vokkero®) are the securely weared lightweight compact Phonak headsets.
Slomo.tv integrated its VAR systems with Vokkero® intercoms. The goal of the integration was to receive audio and control the communication channels between the intercom beltpacks. In accordance with VAR regulations, the communication channel is activated by pressing the red button, which turns on the microphone of the VAR referee's headset and starts recording the conversation between the VAR and the referee on the pitch. As long as the button is pressed, the recording is in progress. A red frame on the referee’s monitor screen indicates that the radio channel is activated and the recording is on. Releasing the button interrupts the communication and stops the recording. Simultaneously with pressing the button, an event mark is created, which facilitates the subsequent search for the desired moment of the conversation of the VAR and/or his assistant (AVAR).
