For the first time, the use of the “Video Challenge” system is being tested in sitting volleyball competitions at the Asia Championship.
According to the Public Relations of the Federation and Tasnim News Agency, the World Para Volleyball Federation has introduced the Video Challenge system to assist referees in making fair decisions during sitting volleyball matches. This system will be used experimentally during the Asia Sitting Volleyball Championship.
The Video Challenge can be applied to five specific scenarios:
Determining whether the ball is in or out of the court
Whether the ball was touched by the defense
Net faults
Touching the antenna by the player or the ball
The player’s buttocks touching the court line during service
Teams have the right to request a challenge under these conditions:
Challenges can only be requested at the end of a rally.
If the team’s challenge is correct, they are allowed up to two unsuccessful challenges per set.
Each team can request only one challenge per timeout.
The process to submit a challenge is as follows: the requesting team presses the buzzer button, the head coach signals the challenge with a rectangular hand sign, then selects the type of challenge and shows it to the referee—all within seven seconds.
The first referee confirms the request and asks the challenge referee to review the video. After the review, if communication devices (headsets) are available, the challenge referee informs the first referee of the result, who then announces it with a whistle. If no communication device is available, the challenge referee stands and announces the result to the first referee, who then signals it with a whistle.
Additionally, if a fault occurs during defense or attack, the challenge referee can review the entire play, even if the fault is only part of the scene
