The relevant TRIPS provision on Broadcasting is Article 14(3), which reads as follows:
Article 14: Protection of Performers, Producers of Phonograms (Sound Recordings) and Broadcasting Organizations
(3) Broadcasting organizations shall have the right to prohibit the following acts when undertaken without their authorization: the fixation, the reproduction of fixations, and the rebroadcasting by wireless means of broadcasts, as well as the communication to the public of television broadcasts of the same. Where Members do not grant such rights to broadcasting organizations, they shall provide owners of copyright in the subject matter of broadcasts with the possibility of preventing the above acts, subject to the provisions of the Berne Convention (1971).

Note that the WIPO treaty negotiations address issues that are similar in some respects to the US disputes in the Aereo case currently under review at the US Supreme Court, although the WIPO negotiation concerns much broader and legally different claims as regards broadcaster rights.
