VideoReferee®-SR is the 7th generation of such systems. It is based on the most successful compact replay server «SimpleR-II» and became the mobile solution for sport video judging of competitions of any level of complexity and importance. The server's dimensions and weight are suitable for hand luggage.
The system records 8 cameras. The referees can analyze the controversial moment frame by frame concurrently from several cameras. If necessary, the video image can be magnified (zoomed in). The slow motion playback is not only used by the judges, but can be included in the television broadcast.
Simultaneous recording of 8 cameras.
Direct integration with scoreboard data or using scoreboard image as PIP.
The server's dimensions and weight are suitable for hand luggage.
Events can be marked live or on recorded video. Events are instantly available for review. When an event is created, the system remembers the currently active channel, and when returning to this event you start with the same view. Marked events are also used to create video reports with controversial game moments.
Using a special vR-Keypad, the operator or assistant can assign with one click different event tags. A special search engine allows you to instantly find the tagged events. For example, all goals of the guest team, or all off site situations by the hosts.
The standard system configuration includes two monitors – engineering interface monitor with built-in multiviewer of all channels and a folder of marked events and referee’s monitor with controller for the video judge. The video judge can work with 1, 2, 3 or 4 cameras simultaneously in live mode or search recorded video. The view from several cameras simultaneously helps accurate and quick decision making. Users are able to create different presets of channels. The system can also magnify any frame for detailed analysis.
Besides the referee’s and engineering monitors, videoReferee®-SR can accommodate a 3rd monitor working as a separate multiviewer. This is convenient when there is a video-assistant who can mark events on live video when the referee’s monitor is used for analyzing recorded fragments. In the case of limited space and/or personnel, all these 3 interfaces can be displayed on a single monitor using the MultiSkin function by one person. The MultiSkin feature is ideal for field work with only one monitor.
The referee’s workplace includes simple and intuitive vR-Controller with functions which can be learned in minutes. Positioning on recorded video with the controller’s Jog/Shuttle is quick and accurate. The Shuttle ring allows you to control the playback speed and slows it down so that judges can view dynamics of the movements by subjects of the controversial situation and notice the smallest details. For analyzing all phases of the movement, videoReferee® allows in addition to frame by frame viewing of recorded video, to view fields. This feature even with the use of ordinary video cameras increases the number of movement phases 2 times to 50 and 60 respectively for PAL and NTSC.
The system uses specially developed technology that allows synchronizing the video even from non-synchronous cameras when parsing controversial moments. In many sports controversial moments are closely related to timing. For example, in ice hockey, a goal scored after time stoppage does not count, in basketball successful throw 0.1 sec. before the end of the game or attack time is counted. That is why the judges must have access to official game data.
The videoReferee®-SR has two ways of solving this problem: using a special interface receiving data directly from scoreboard or by selecting the appropriate scoreboard view and displaying it as PIP. In both cases, information is recorded in each video channel of the system.
If all 8 channels do not contain the necessary scoreboard image, then the optional dedicated camera input device is used. It can use either SDI or inexpensive HDMI cameras.
Unlike all other similar systems, videoReferee® can work with 720p and 1920i cameras on the same project.
TV viewers are eager to see the decision making process. If this is not prohibited by the league rules, the referee’s monitor image via optional SDI output module can be provided for broadcasting.
Many sports federations require a video report in the form of H.264 or MPEG files. In addition to marked moments the system can batch export with the use of one button all video channels, which significantly reduces the time spent export.
It is worth mentioning that videoReferee®-SR is based on SSD. This made the system more reliable, insensitive to vibrations and at the same time with video storage many times exceeding the storage size of systems with large dimensions.
