Signing a deal to maintain terrestrial television for the foreseeable future could result in significant changes for the six countries, it said.
Coverage has been shared between the BBC and ITV since 2016, but the current deal will expire after this year’s tournament.
There were fears that the Six Nations could disappear from free-to-air television, but tournament bosses took steps to downplay these concerns.
According to the Scotsman, the BBC and ITV believe they could be persuaded to renew their contracts with the promise of more night-time matches.
Ofcom said events such as Wimbledon, the Grand National and the FIFA World Cup should be shown on terrestrial channels, but the Six Nations do not fall into that category.
Free-to-air coverage boasts a broader reach than subscription channels, but traditional broadcasters often cannot compete in terms of the revenue they can deliver.
As a result, a revamped schedule of fixtures with more evening kick-offs is said to be being considered. The proposed move could help the free-to-air broadcaster land more ‘prime time’ fixtures as it contracts.
The BBC and ITV are still believed to have discussed a new broadcasting deal with their six-nation bosses, and it remains to be seen whether an agreement occurs.
But now this year’s tournament is set to take place as Wales face France in a curtain raiser next weekend.
A 20-minute red card trial in the Autumn Nations Series will be played during the tournament. Scrum-Halves also provide more protection from Rucks and Mauls, while throwing non-strains on non-consecutive line-outs is not punishable.
Players will continue to have less time to transition and form scrums and line-outs, while referees will continue to broadcast key decisions to fans in the stadium.
Ireland are favorites to retain the title even without Andy Farrell, who has been released from coaching duties as he prepares to take charge of the British and Irish Lions.
Meanwhile, England will be hoping to bounce back from a disappointing year by posing their own title challenge.
Steve Borthwick has already had to shake up the team at short notice, with injuries to former skipper Jamie George, Alex Mitchell, Jack Van Poortvliet, Alex Coles and Alex Dombrandt.
