Adelaide: Cricket's Decision Review System (DRS) was in the spotlight in the Ashes test between Australia and England in Adelaide as both captains had to make quick decisions time and again on whether to challenge the umpire's call.

No less than 17 decisions were referred to the DRS technology for the third umpire to review, of which seven were successful in having the original call overturned, while on 10 other occasions the umpire's original decision was upheld.

Captains are allowed two unsuccessful reviews per innings, after which the on-field decision cannot be challenged. The reviews are used mainly for leg before wicket decisions or when the batsman has been caught after getting a thin edge.

Australia captain Steve Smith could have rued his impetuousness in the second innings, when he burnt his two appeals relatively early and had to live with the umpire`s decisions thereafter.

Smith acknowledged the difficulty of having to make more or less instant decisions whether to review decisions that are often decided by millimetres.

"It's a tough one," he told reporters after Australia beat England in the second test on Wednesday.

"I certainly think my thought process around it has changed a little bit (whether to risk calling for a review early in an innings). Sometimes it's more hope."

"It's something I can, in particular, continue to work on and try to get as consistent as I can."

England captain Joe Root, meanwhile, said decision-making was tough on both the umpires and captains.

"It's easy to criticise the umpires and make excuses but it's a very difficult job and just like players you have good or bad days," he said.

Root looked at the bigger picture of the DRS technology, and whether it somehow could be improved.

DRS uses technology that tracks the path of ball and predicts what it would have done for lbw decisions.

It also uses audio and infra-red imaging for catch decisions to detect temperature changes as the ball strikes bat or pad.

"Is the tech in the right place, could it be better?" Root said. "We are where we are with it. If we use it as an excuse it`s not going to help us."
