"Those are the only two events that we've confirmed that this will be in place at the moment," the ICC's umpires and referees boss Adrian Griffith told The Herald and Age. "It will be up to the members how they want to take this forward."

Missed no-balls have become a major frustration for players, coaches and commentators, with many believing on-field umpires should be relieved of the duty of calling bowlers who overstep.

Australia's James Pattinson and Pakistan teenager Naseem Shah were among those this season who were denied a wicket this after the mandatory check of the front foot. Channel Seven reported that as many as 21 balls were not called in the first two sessions of day two of the Gabba Test between Australia and Pakistan in November.

At Cape Town last month, there were 12 no-balls not detected in a session between England and South Africa.

World cricket's governing body first trialled the system in 2016 only to decide in 2018 not to push ahead as it was not cost-effective, but the ICC's general manager of cricket, Geoff Allardice, last week said significant improvements had been made.

The system, which is using broadcast cameras, is now more cost-effective with minimal impact on the flow of the game, Allardice said.

The groundbreaking move comes after three trials over 12 matches in which 13 of the 4717 deliveries bowled (0.28 per cent) were called.

The ICC found it takes an average of 17 to 20 seconds from the moment the bowler lands their foot to a call being made on the field, which Griffith conceded was "a little longer than we would have liked". This includes the three-second delay between the foot landing to when the umpire can start assessing video, Griffith said.

On-field umpires will be instructed by the video umpire to delay play if a decision cannot be made before the bowler is ready to deliver the next ball.

"Most of them have been very clear. If it's a tight one, the umpire will indicate there's been a check and the on-field umpire will delay play to check if the delivery is a no-ball," Griffith said.

"During the trial there were no major issues. If it's close the umpire will take the time to satisfy themselves."

If the technology works well at the World Cup, which the ICC is confident it will, there will likely be a push to bring it into bilateral series. One potential drawback could be the games held by smaller cricket nations with broadcasters who do not have TV cameras that can provide the number of frames required.

"Everything is a possibility," Griffith said. "Those decisions need to be ironed out at the next board meeting. We will have it in our events moving forward and have a discussion on when we can move that forward to bilateral cricket.

"If we can use technology that has minimal impact and can give the game the correct result, we think that's a good thing to do.

"We're putting it into our events, the ladies are the trailblazers."
