Five Leading Electronics Manufacturers Announce Licensing
of Digital Transmission Content Protection Method

(SAN JOSE, September 23, 1998) Hitachi, Ltd., Intel Corporation, Matsushita Electric Industrial Co., Ltd., Sony Corporation, and Toshiba Corporation today announced the availability of a copy protection method for copyrighted content transferred across digital interfaces such as the IEEE1394. The Digital Transmission Licensing Administrator (DTLA), an independent licensing authority established by the five companies, will begin licensing the Digital Transmission Content Protection (DTCP) method to interested businesses on September 23, 1998.

The rising popularity of digital AV/IT electronics products has spurred interest by the entertainment, electronics, and broadcast industries in adopting methods to protect digital content transferred between electronics products such as personal computers, DVD players, set-top boxes and digital television sets.

In February 1998, the five companies presented the DTCP method to the Copy Protection Technical Working Group (CPTWG), an ad-hoc cross-industry body organized to evaluate content protection technologies. The five companies subsequently established the DTLA in June 1998 to simplify licensing procedures and promote swift acceptance of the DTCP method by content providers, electronics manufacturers, and broadcast service providers.

Detailed technical information concerning the operation and implementation of the DTCP method is available through the DTLA pursuant to the terms of a nondisclosure agreement. The necessary export license authorizations have already been secured from the governments of the United States and Japan. Both a technical white paper describing the DTCP method and licensing information from the DTLA can be found on the Internet at

Businesses interested in licensing the DTCP method should contact:
