The Supreme Court will likely rule in favor of television networks, which argue online service provider Aereo committed copyright infringement by retransmitting programs, CBS CEO Les Moonves told CNBC on Friday.
"We think we're going to win," Moonves said on "Squawk on the Street," noting U.S. Solicitor General Donald B. Verrilli Jr. came out in support of TV networks earlier this month. "The percentage of cases that go with the solicitor general are very high—somewhere in the 75 to 80-percent range—so we're confident."
Aereo, backed by billionaire Barry Diller's IAC/InterActiveCorp, does not pay broadcasters for use of programming that it retransmits to subscribers. Its users pay a low monthly fee to watch live or recorded programs on their computers or mobile devices.
Last year, a federal appeals court in New York ruled in favor of Aereo in a similar lawsuit. Broadcasters appealed to the Supreme Court, which will hear the case at end April. A decision is expected by the end of June.
Moonves said the pending decision is "nothing I lose sleep over," though, because he has a plan that will allow his network to "win either way."
"If we don't win, we have other ways of making up for it," Moonves said. "Putting our shows directly on cable, forming our own Aereo with other networks, going over the top. Lots of solutions. No fear on my part."
