MP3
MPEG 1 or 2, Layer 3, or MP3, is an audio compression standard that allows tracks from an audio CD to be compressed into a digital file 1/10 of its original size. Once compressed, songs can be easily stored on a hard drive for playback on any Personal Computer, with virtually no loss in sound quality. Users can manage their music collection on their PC, home stereo connected to the PC, or Internet radio station. The small size of MP3s allows for hours of music to be stored rather than the one-hour limit of traditional CDs. |

RIAA - (riaa.org)
The Recording Industry Association of America (RIAA) was founded in 1952. The RIAA is the trade group that represents the U.S. recording industry. Its mission is to foster a business and legal climate that supports and promotes members' creative and financial vitality. Its members are the record companies that comprise the most vibrant national music industry in the world. RIAA© members create, manufacture and/or distribute approximately 90% of all legitimate sound recordings produced and sold in the United States. In support of this mission, the RIAA works to protect intellectual property rights worldwide and the First Amendment rights of artists; conduct consumer industry and technical research; and monitor and review state and federal laws, regulations and policies. The major record groups represented by the RIAA include: Sony, EMI, BMG, Time Warner, Warner Music, Seagram, Universal and Bertelsmann. |
Audio Home Recording Act (AHRA)
In 1992 President Bush signs the Audio Home Recording Act. Defined by many a historic compromise, the ARHA is the first official document to recognize the consumer’s right to use and the retailer’s right to sell, all equipment able to record and duplicate, both in digital and analogue form. Duplication is limited to domestic use and as such, the ARHA allows only a first generation of copies but prohibits serial use of the equipment for commercial purposes. The compromise requires payment of a modest fee which is to go to the first "person" involved in the distribution process, the production or import company; no monetary compensation is required from the retailer or the end user. The sum, established as a percentage, is managed in common by the "Register of Copyrights" and by the "Librarian of Congress": two thirds of the amount will go to the Sound Recordings Fund and one third to the Musical Works Fund. |
Digital Millennium Copyright Act (DMCA)
The DMCA (Digital Millennium Copyright Act) is a law passed by the Clinton Administration on 28 October 1998 on the basis of suggestions by the WIPO (World Intellectual Property Organization) and consists of 5 articles devoted to the "protection" of copyright in the digital age. The first article of the DMCA deals in particular with the technological aspects related to copyright, defining new classes of offence:
The question remains of Copyright Management Information (CMI). This is only a sort of electronic watermark containing information on the work in question, the author, the copyright owner and other similar information. Fortunately, the CMI is strictly forbidden to contain information on the user holding the object. In this case also, the law provides for two possible offences:

Secure Digital Music Initiative (SDMI) - (sdmi.org)
The Secure Digital Music Initiative is a forum that has brought together more than 200 companies and organizations representing information technology, consumer electronics, security technology, the worldwide recording industry and Internet service providers. SDMI's charter is to develop open technology specifications that protect the playing, storing, and distributing of digital music such that a new market for digital music may emerge. The open technology specifications released by SDMI will ultimately:

Peer-to-Peer (P2P)
Peer-to-Peer is a network model where each computer connected is simultaneously able to offer and request a service with parity and in a decentralized manner. In the case of P2P networks with "file-sharing" or "file-swapping" functions, the computers request and send files and supply services questioning the shared files. |
Napster
Napster is a Peer-to-Peer protocol enabling sharing of MP3 files amone users of customer program Napster, downloadable free of charge from the site napster.com. The search for musical documents in the directories shared by users is carried out by a central server indexing the musical documents and adressing their transfer. The Napster central server contains only the list of songs made available by users, the real MP3 files reside only in the computers of individual users and are never transferred into the Napster server. The company says its software aims to make finding MP3 files easier on the Net. |
Gnutella
Gnutella is a Peer-to-Peer protocol with a substantial difference from Napster: user-shared files are not searched by a central server but in a decentralized manner by the Peer-to-Peer network itself. Gnutella was designed to connect up to the entire network of users, establishing a link with any one of them. In short, a Gnutella client connects to another Gnutella client who,in turn, connects to another Gnutella client, using a method similar to word-of-mouth to perform document search. A Gnutella client is also a Gnutella server and this characteristic makes the protocol technically and legally attack-proof. Gnutella does not belong to a company and any responsibility can only be attributed to the end user: the person who shares the file. In comparison with the centralized search by Napster, the only disadvantage of Gnutella is the high consumption of network resources by each user. Apart from MP3 files, the Gnutella protocol enables any other type of document to be shared. |
The Case of Felten vs. SDMI
Edward Felten, professor of informatics at the University of Princeton, decided to participate in the "watermark" challenge issued by SDMI. In a short time, with his assistants, he managed to crack 4 of the 6 "watermarks, showing the weakness of the system designed by SDMI. Felten at this point could have won $10,000 for each watermark he cracked. But the competition rules were that all information on possible cracking of the watermarks should not become public. Felten refused the prize: "I believe that the public, musicians and composers have the right to know if the technology they have to purchase doesn’t work. And then, this could be a very dangerous precedent...". He decided to present the documentation in public at the Hiding Workshop Conference in Pittsburgh the following April. In a letter, SDMI warned Felten that divulging the material in question would be a violation of the Digital Millenium Copyright Act (DMCA), which forbids the diffusion of information which, even indirectly, might favour the violation of intellectual property. The Pittsburgh event was cancelled. Edward Felten and his assistants (supported by the Electronic Frontier Foundation), decided to take legal action in the belief that this use of the DMCA violated the freedom of expression enshrined in the First Amendment of the Constitution. Edward Felten lost the case. The academic world supported Felten and showed great concern about possible future conflicts between laws defending intellectual property and freedom to do research and divulge scientific information. |
Is Napster hurting record sales?
The RIAA identifies MP3-sharing as the cause of the drop in the profits of record companies. The products most affected are CD singles, which in 2000 fall to almost 40% less than the previous year. A statistical study commissioned by the RIAA reports that 23% of those interviewed do not buy CDs because they practice Peer-to-Peer. In May 2001, Jupiter Research publishes a new statistical study on the phenomenon with a research sample of 3,319 people: it finds that 34% of habitual MP3-swappers are buying more CDs than ever before and that only 14% have stopped all purchases. Jupiter Research finds that sales in 2000 have dropped only for: audiotape and CD singles, audiotape compilations, vinyl records and music videos. Sales of CDs have risen by 3%; probably not as much as the record companies had hoped. Others attribute the cause of the drop in sales to the exorbitant price of CDs. |
A large directory for everyone.
FastTrack, Audiogalaxy, opennap, Gnutella and the great variety of protocols and clients available are often used simultaneously by the same file-swapper, who tends to group documents on their own computer in a single directory. An "exchange area" independent of the type of P2P technology used. A huge bank of contents digitised and available to anyone. Some call it: "A new, spontaneous social practice, A new culture". Others: "An illegal practice, a vice to be fought against". Different views of a visibly rooted phenomenon. |
Denial of Service (DoS)
Denial of Service is a class of computer attacks which can be carried out via a computer network. The aim of a DoS is to cause disruption to a net service. Using particular techniques, the "target service" is subjected to more requests than it is able to supply. |
High Fidelity MP3
In 2000, Texas Instruments purchase Burr-Brown, an American company manufacturing DACs (Digital to Analog Converters) for high quality reading of Audio CDs. The result of the collaboration between the two companies is a new generation of DSP (Digital signal processing)chips. The excellent performance of these chips in reading MP3 formats persuade many Hi-Fi enthusiasts of their quality. "Imagine never buying another music CD or cassette. No hissing, no skipping, no matter what. One of the hottest new uses for the Internet is downloading music. MP3 files are populating the web by the hundreds of thousands. Manufacturers are building the devices. The whole music world is changing. And this is creating tremendous growth opportunities for the companies that get there first." (Texas Instruments. Internet audio: Overview). These chips cost around 4 dollars each. |
