Recent "Digital Copyright" Legislation: U.S. DMCA (Digital Millennium Copyright Act) The debates in the House and Senate preceding the signing into law of the DMCA by U.S. President Clinton in October 1998 indicated that the principal object of the Act is to promote the U.S. economy by establishing an efficient Internet marketplace in copyrighted works. The DMCA implements the two 1996 WIPO treaties (WIPO Performances and Phonograms Treaty and WIPO Copyright Treaty) and addresses a variety of issues that arose with the increased availability of content in digital form. The Act 1) creates a series of "safe harbor" defenses (which are subject to a variety of conditions that must be met) for certain common activities of ISPs (Internet Service Provider), 2) bars the circumvention of technological protection measures that protect copyrighted works, 3) prohibits the distribution or provision of false copyright management information with the intent to induce or conceal infringement, 4) establishes an exemption for making a copy of a computer program for purposes of maintenance or repair, and 5) contains provisions concerning the "webcasting" of sound recordings on the Internet and the making of (digital) copies of copyrighted works by nonprofit libraries and archives. A full-text version of the DMCA is available from: The Library of Congress: Thomas (Legislative Information on the Internet): http://thomas.loc.gov/cgi-bin/cpquery/z?cp105:hr796: Moreover the U.S. Copyright Office provides a memorandum, which briefly summarizes each of the five titles of the DMCA (pdf format): http://lcweb.loc.gov/copyright/legislation/dmca.pdf The DMCA has been criticized for not clarifying the range of legal principles on the liability of ISPs and creating exceptions to only some of the provisions; therefore giving copyright owners even more rights.

Proprietary Network Proprietary networks are computer networks with standards different to the ones proposed by the International Standardization Organization (ISO), the Open Systems Interconnection (OSI). Designed to conform to standards implemented by the manufacturer, compatibility to other network standards is not assured.

Satellites Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure. On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from fiber optic cables, so point-to-multipoint transmission increasingly becomes the ruling satellite technology. Point-to-multipoint transmission enables the quick implementation of private networks consisting of very small aperture terminals (VSAT). Such networks are independent and make mobile access possible. In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
