Due to the cost of television cameras and other equipment needed for a video referee to function, most sports only employ them at a professional or top-class level.Cricket
In cricket, the video referee is referred to as the
third umpire . The third umpire is called upon to adjudicate by the two on-field umpires where they are unsure over a decision of a dismissal or boundary.Field hockey
Video umpires are used in top-level FIH events to assist the on-field umpires. The match umpires may refer decisions to the video umpire when they are uncertain of the correct decision relating to the awarding or disallowing of goals.

Rugby league
Video referees are also used in rugby league in the domestic
National Rugby League (Australia/New Zealand), Super League (Europe) as well as in international matches. In rugby league the video referee can be called upon by the match official to determine the outcome of a possible try. The "video ref" can make judgements on knock-ons, offside, obstructions, hold-ups and whether or not a player has gone dead, but cannot rule on a forward pass. If a forward pass has gone un-noticed by the on-field officials it must be disregarded by the video ref, as such judgements cannot reliably be made due to camera angle effects.Rugby union
In rugby union the video referee is officially referred to as the Television Match Official (TMO) and is used mainly in international and professional games. The TMO can only be used in the situation where the referee is unsure whether a try or goal attempt has been scored, or in the event of foul play in-goal.
