THE AFL's controversial video score review system is set to remain in place until a suitable high-tech replacement can be found.

The system has repeatedly come under fire this season, with the vision used to review scores often providing inconclusive, especially when used to determine whether a shot has been touched or has crossed the line.

"There are two options, really, for this year - you can either run the system that we have got or you can get rid of it and just go back to the goal umpire's call," AFL football operations general manager Mark Evans said on Monday.

"At the moment, the system provides the opportunity for us to reverse something that was a very clear error.

"The issue for us that we're monitoring, and we'll need to watch across the rest of the season, is that there appears to be far more inconclusive episodes this year than there was last year."

'Non-review' was wrong: AFL

Asked whether the current system was guaranteed to last out the season, Evans said: "No. I'd say we'll keep watching where we're going at the moment.

"(But) if it's going to reduce the error rate by (getting rid of) the absolute shockers, then I think it stays while we assess other options."

The League is currently involved in a global search to try and find a long-term system for score reviews.

"My personal view is that micro-chipping the ball will lead us down a path towards as better solution," Evans said.

"But there are other systems that are camera-based systems … others that use a magnetic force.

"In terms of what we can do, we've certainly contacted some technology providers in the past, and I think there'll be a technology solution over time.

"None of them, at the moment, correctly identify where the ball is in flight, whether it's been touched off the boot, whether it's gone left or right of the post.

"So we'll keep working with some of those providers to see if there's a better system for us."

As for when new technology might be introduced: "That's dependent on when we can find the right technology, first of all, then you'd need to have an appropriate time-period where that's tested.

"So I don't think it'll anytime soon."

Finding a score review system that is affordable is a key challenge for the AFL.

"There's a new system that's about to come in place for soccer – Goal Connect – and they're talking a fit-out of $250,000 per stadium and a $2,000 to $4,000 fee per match," Evans said.

"The question for us is: does it actually suit our purposes or not? So we'll talk to those people and perhaps even see if they can come out and run a trial for us."
