In addition to the domestic policy implications raised by broadcasting on the Internet, there are important international considerations as well. The U.S. has obligations under the Berne Convention for the Protection of Literary and Artistic Works (Berne), the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPs), and the recently ratified WIPO Copyright Treaty (WCT) that relate to broadcasting and Internet transmissions. In particular, to the extent that Congress considers the option of compulsory licensing of broadcast television signals for retransmission on the Internet, Berne imposes specific limitations on member countries' ability to impose such licenses.
