videoReferee®-4 – Powerful Video Assisted Review system for any sport
A truly versatile series of video-refereeing and VAR systems developed and manufactured by SLOMO.TV.
The number of recording channels is sufficient for virtually any competition in soccer, hockey, basketball, volleyball, handball, canoe slalom, and other sports. Any level of complexity and importance.
The videoReferee®-4 series includes 3 different hardware platforms – videoReferee®-4, videoReferee®-4A and videoReferee®-4G.

16 3G/HD-SDI recording channels
Comfortable and quick review of controversial moments
Second independent workplace
Integration with scoreboard controllers (match-controllers)
Export of the selected video materials for further analysis
Gesture-based interface for referee's monitor
Suitable for Hockey, Football, Basketball, Handball, Water Polo, Wrestling, Speed skating, Fencing, Short track and other sports
Up to 16 Full HD cameras
The multi-camera system provides the ability to analyze the controversial moments synchronously from several cameras, frame-by-frame or in slow motion. The referee's interface can be outputted to a review area monitor or TV broadcaster (RRA option).
Work with non-synchronous video sources
videoReferee® can be used with cameras without external synchronization. Specialized technology, developed by SLOMO.TV, allows synchronizing video streams from non-synchronous cameras when analyzing controversial moments.
Comfortable and quick analysis of controversial moments
videoReferee®-4 systems have all necessary functions for comfortable refereeing:
- event marking and synchronous search on recorded video;
- a convenient high-performance interface for quick preparation of video material;
- ability to review the video from 1 or 4 cameras simultaneously frame-by-frame or in slow motion;
- zoom in/out for detailed review;
- integration with the most popular scoreboard controllers.
Workplaces
The system has 4 graphic ports for connecting interface monitors. The video referee's workplace is equipped with a standard or MultiTouch monitor for working with the gesture-based interface. A specialized control panel, Control-VR, provides instant access to all available cameras, presets and most of the functions. The Control-VR is included with the system, the monitors are provided by the user.
Gesture-based interface for referee's monitor
Support for the gesture-based interface is available as a basic feature. It greatly speeds up and simplifies the video referee's work with the system. Using the gesture interface, the referee performs all the necessary actions with simple and intuitive gestures: camera selection, search, display control (1/4 camera), zoom in/out, playback speed control.
Integration with scoreboard controllers
SLOMO.TV systems are integrated with the most frequently used scoreboard controllers. Official game information – teams, time, score – is displayed in each video window of the system and is updated in real time.
Currently, the system supports the following widely used scoreboard controllers: Westerstrand, Nautronic NTpult, Nautronic NAUCON-1000, Bodet, Omega Saturn, Megalux, NataInfo, Victory, VITA, Araneus-Nglight, ElTablo, Stramatel, Colosseo, CEDR, Favero Console-700.
Export of video material to external media
The system records signals from all cameras on the built-in HDD or SSD-based disk array. After the end of the match, all the recorded material or only clips containing the selected moments can be exported in H.264 format to an alienated digital media for submission to the League's office or for further analysis. If the system is integrated with a match-controller, official game information (time, score, period) is displayed on each channel.

videoReferee®-4 systems have a wide range of options to cover all additional needs.
- SSD or HDD-based built-in storage
- RRA option: SDI output of the referee's monitor to arena and/or TV broadcaster
- Second independent workplace (for SSD-based systems)
- Remote operation (for systems with 2 fully-functional workplaces)
- Expansion of the built-in storage capacity
Disk subsystem
The videoReferee®-4 servers can be ordered with a disk subsystem based on HDDs or on lightweight and high-performance SSDs.
RRA option: the SDI output of the referee's interface
This option provides a separate SDI output for displaying the referee's interface on the monitor at the Referee Review Area (RRA). The same output can be provided to the broadcaster. In this setup for confidential and secure review the output is activated only after pressing a special button. The picture changes from a still background to the video, prepared for review by the main referee. Players, coaches and spectators do not see neither the preparation of the video material nor what the main referee sees.
Second independent workplace
The SSD-based videoReferee®-4 systems allow the user to accommodate an additional independent and fully-functional workplace.
Remote operation
The second workplace can be used for remote work with the system via the Internet.
Expansion of the built-in storage capacity
videoReferee®-4 systems can be ordered with increased built-in storage capacity: 2x or 4x (up to 320 hours of Full HD video).
