Part of the DMCA.
DMCA Title I has two main portions, one of which covers several legislations already implemented in US copy prevention laws and the other which is often known as DMCA anti-circumvention provisions. The latter portion of this title gave way to laws being passed that made all analog video recorders come with a copy protection schema known at one time as Macrovision. This title also includes several guidelines against reverse engineering of a media product.
