Former England captain Michael Vaughan says TV cameras should be placed on Decision Review System operators in order to provide “transparency”.
England have been frustrated by a number of DRS decisions during their ongoing tour of India.
“I’m not saying anyone is cheating,” said Vaughan.
“I’m trying to give an answer for when a decision is made and we all disagree with it. If the person on Hawk-Eye is filmed it puts the noise to bed.”
Basingstoke-based Hawk-Eye is providing the ball-tracking information for England’s series in India.
England’s Joe Root appeared to be aggrieved on the third day of the fourth Test when he was given out on review to India off-spinner Ravichandran Ashwin.
In the same Test, England benefited from four ‘umpire’s call’ lbw decisions during India’s first innings.
Earlier in the series, England captain Ben Stokes disagreed with opener Zak Crawley being given out to left-arm spinner Kuldeep Yadav during the second Test in Visakhapatnam.
Then, after the third Test, Stokes and coach Brendon McCullum engaged in a discussion with match referee Jeff Crowe after Crawley again was given out to Jasprit Bumrah.
At the time, Stokes called for ‘umpire’s call’ to be removed from the DRS system.
“You just want something that is consistent,” Stokes told BBC Sport. “Umpire’s call, personally I think we should just get rid of it. If it’s hitting the stumps, it’s hitting the stumps, then it’s a level playing field.”
Vaughan, who led England in 51 of his 82 Tests, told the Test Match Special podcast on Sunday: “I can understand supporters on both sides being frustrated with the decisions that have been made. It doesn’t look like Hawk-Eye is having a great series.
“The most important operators of decisions now are in the trucks. We need to have a camera in the truck to give an understanding of how it all comes to that decision.
“All I want is full transparency. If it takes the International Cricket Council employing someone to put in the trucks for integrity, they have to do that as well.”
Conversations between the third umpire and the on-field officials are heard in stadiums, and on television and radio broadcasts.
“For the game in general, for people watching, we need to see who is operating, because the person operating the technology is more important than the umpires,” added Vaughan.
India ended the third day of the fourth Test on 40-0, needing another 152 runs to beat England and take an unassailable 3-1 lead in the series.
