4C Companies
Four companies (IBM, Intel, Matsushita, and Toshiba) (the “4C” companies)
have developed a number of technologies for the protection of digitized
copyrighted works. The 4C’s Protection for Pre-recorded Media (“CPPM”) and
Content Protection for Recorded Media (“CPRM”) protect digitized copyrighted
works distributed or stored on portable storage media. CPPM, which uses
encryption and watermark detection to protect content in pre-recorded digital
media, has been adapted for works distributed in the DVD audio format.
CPRM protects audiovisual, literary and other copyrighted works stored on a
variety of optical and flash memory-based storage media, including DVD-R, DVD-RW,
DVD-RAM, SD Memory Card and Secure CompactFlash. CPRM provides for encryption of
“copy once” content and includes the obligations to recognize and respond to
watermarks and copy control instructions in content entering unprotected inputs.
Both CPPM and CPRM include robust encryption of copyrighted material and
implicit authentication of recording and rendering products via storage
media-based broadcast encryption. The cryptographic cipher used for both CPPM
and CPRM (the “C2” cipher) is licensed separately by the 4C Entity for certain
uses, such as encrypting content stored on a fixed hard drive for “time
shifting” purposes.
The 4C companies have proposed a framework for the integration of otherwise
independent content protection technologies – the Content Protection System
Architecture (CPSA). CPSA combines encryption, authentication and watermarking
technologies with licensing agreements. Under the CPSA model, content is
encrypted and transmitted digitally only via protected outputs and only to
devices that are bound to provide a minimum level of persistent protection and,
in some cases, to respond to usage rules conveyed by associated watermarks. CPSA
includes Digital Transmission Content Protection (DTCP) technology developed by
the 5C companies (discussed below). More information on the 4C companies is
available at: http://www.4centity.com.
5C Companies
The 5C companies (Intel, Hitachi, Matsushita, Sony, and Toshiba) work
together to develop technologies to protect copyrighted works in digital format.
The 5C companies designed Digital Transmission Content Protection (DTCP)
technology to protect audio and audiovisual content from unauthorized copying,
interception and tampering within a localized network. DTCP technology is used
to protect compressed content from unauthorized access as it travels over
digital buses. By way of illustration, DTCP technology may be used to protect
the “link” between a set-top box receiver and a DVD recorder or a digital
television monitor. DTCP technology is used to ensure that DVD content is sent
via digital outputs only to devices that will recognize and follow any
associated copy control instructions. The Digital Transmission Licensing
Administrator (DTLA) licenses DTCP technology. More information on DTLA is
available at: http://www.dtcp.com and on DTCP technology at:

Copy Protection Technical Working Group (CPTWG)
The Copy Protection Technical Working Group (CPTWG) is an informal forum for
content creators and owners, consumer electronics and computer companies, and
interested consumers and consumer advocates to discuss technical issues related
to content protection. CPTWG seeks consensus on technological solutions for
various content protection challenges, including protecting in the DVD home
video market from casual piracy. The CPTWG began by launching an encryption
approach called Content Scrambling System (CSS) in 1997.
In November 2001, the CPTWG established the Broadcast Discussion Group (BPDG) to
address the protection of digital broadcast television signals against
unauthorized redistribution. More than 70 representatives of the motion picture,
consumer electronics, computer and information technology, cable and broadcast
industries, as well as individuals and representatives of consumer and civil
liberties groups, participated in that process. In June 2002, the BPDG completed
a technical evaluation of the Broadcast Flag technology, which provides a means
of preventing unauthorized redistribution of digital broadcast television
content outside the personal digital network environment. As noted above, the
FCC currently is conducting a rule making with respect to a number of technical
and enforcement issues related to the Broadcast Flag. More information on CPTWG
is available at: http://www.cptwg.org.
