The Guardian today reported the free-to-air broadcaster has been in discussions with Sky but has not said whether talks are continuing.
While ITV today refused to comment publicly on the story a source indicated there are no ongoing talks. Sky refused to comment.
Charging for its content would be a major shift in strategy for ITV, reducing its reliance on advertising revenues while damaging its ability to pull in mass audiences.
ITV2 has become the most-watched non-sports digital channel in the UK thanks to the success of Freeview and content such as 'American Idol'.
Any decision to shift its digital channels to subscription would almost certainly be one for a future chief executive of ITV to take.
The broadcaster is currently conducting the search for a chief executive to succeed executive chairman Michael Grade and the process is expected to be completed before the end of the year.
In February, before it was revealed Grade was stepping down, ITV surprised the industry by suggesting it could merge with Channel 4 and Five in a "blue sky thinking" submission to the Government's Digital Britain consultation about the future of public service TV.
ITV's relationship with Sky is complicated by the fact Sky is its major shareholder, with a 17.9% stake.
Sky is currently appealing against a Competition Commission decision forcing it to sell down its stake to less than 10%.
