The broadcaster recently stopped airing some of ITV's biggest dramas, including ratings-winner Doc Martin and long-running police drama The Bill, in an effort to air more Scotland-focused shows.
In autumn, STV only aired one new ITV drama, Murderland, which was set in Scotland and starred Scottish actor Robbie Coltrane. At the time, STV chief executive Rob Woodward explained that the strategy was merely to create "more space in the schedule".
The Scottish broadcaster also later mooted plans to scrap the ITV Evening News from its schedule, replacing it with a programme delivering a "Scottish perspective" to news coverage.
However, The Greatest Scot, broadcast over a week in November, could only muster 13% of the viewing audience, much lower than the 30% average for ITV's event drama Collision, which launched with 7.5 million viewers.
Following a 12% drop in all-day audience share over the last year and a reported profit loss of 82%, STV has now been forced into a strategic rethink.
Speaking to the Sunday Times, Woodward said: "We hope our audience will be pleasantly surprised when we unveil our schedule in the New Year. You can expect to see some more of ITV's drama back on the screens.
"When we schedule high quality, home-produced content it attracts a strong audience. What doesn't work is relying on old repeats or film stock."
STV is also currently locked in an ongoing financial dispute with ITV over an alleged programming debt and video on demand rights.
In future, the ITV licence-holder in Scotland wants to become more independent from the ITV Network in a relationship similar to Irish broadcaster TV3, which can purchase whichever programmes it wants but at market rates.
