Title I implements two World Intellection Property Organization (WIPO) treaties: The Wipo Copyright Treaty and the WIPO Performances and Phonograms Treaty adopted at the WIPO Diplomatic Conference in December 1996. The treaties have two major portions. One portion includes works covered by several treaties in U.S. copy prevention laws and gave the title its name. The second portion (17 U.S.C. 1201) is often known as the DMCA anti-circumvention provisions. These provisions changed the remedies for the circumvention of copy-prevention systems (also called "technical protection measures") and required that all analog video recorders have support for a specific form of copy prevention. The section contains a number of specific limitations and exemptions, for such things as government research and reverse engineering in specified situations.
