AUSTIN, Texas (AP) Racetrack owners are seeking the approval of state regulators to expand gambling to include racing terminals that look similar to slot machines.

The owners see the machines, known as historical racing terminals, as an important revenue stream that could boost a struggling industry.

Proponents argue that state law does not specify that pari-mutuel betting be only for live horse races. The Austin American-Statesman reports (http://bit.ly/1uLdoGJ ) they want to include the racing terminals, which display video feeds of previous horse races. The feeds are stripped of any identifying information that could aid the bettor.

Slot machines are illegal at Texas tracks and critics of the effort say the terminals are nothing more than horse-themed slots.

The Texas Racing Commission will consider the matter Tuesday but will not make a decision.
