The Scottish Professional Football League has been accused of selling the television rights to SPFL matches for a tenth of their true value.
Leading sports accountant Charles Barnett has said that Scottish football risks falling further behind English football if the mistake is not rectified when the contract expires.
"To put the current financial anomaly into perspective, the £20million cost of showing two English Premiership games on Sky is more than all of the broadcast fees that Scottish football receives in a year," Barnett told the Daily Record.
"Simple arithmetic indicates that if Sky and BT are happy to pay £1.712billion a year for English football the comparable figure for Scotland should be £142million. To be getting just over one 10th of that at £15m is unfair and unsustainable.
"The hierarchy of Scottish football must start to lobby for more money. It is unlikely they will get £142million from broadcasters but even another £20m or £30m, which compared to the investment in the English Premiership is a drop in the ocean, would make an enormous difference to the game in Scotland."
The current television rights deal expires in 2017.
