BT is understood to be seeking full ownership of on-demand and catch-up service YouView.
The company already owns a stake in the platform, along with TalkTalk, the BBC, ITV, Channel 4, Channel 5 and Arqiva.
However, publications including the Telegraph are reporting that BT will pay up to £60 million in order to own it outright.
It is understood BT had initially bid less than £20 million to purchase YouView, but stakeholders including the BBC and TalkTalk have pushed for a much higher price.
No official comment from any party has yet been made, but reports state that if BT succeeds in the buyout, it would step up its focus on pay-TV to fend off competition from the likes of Virgin Media and Sky, both of whom are updating their set-top boxes.
The BBC is believed to be the main obstacle to any sale, as it has used considerable sums of licence fee payers' money to subsidise the project, which had been conceived as a replacement for Freeview.
