The two groups have engaged in a legal battle since the French group's surprise decision to pull out of an April 2016 contract which would have handed it full control of Mediaset's pay-TV unit Premium.

An Italian judge had asked the two companies to seek an agreement over the case. Sources close to the matter have said that the two sides are in talks over a possible deal.

The Milan-based TV group had been seeking to enforce the sale contract.

Mediaset and the Berlusconi family's holding company Fininvest, which owns just under 40 percent of the broadcaster, are seeking 3 billion euros in damages.

The source said the postponement request would be made at the start of the Dec. 19 hearing.
