Select a topic or year

Burbank, CA - 03 Mar 1999: - IBM, Intel, Matsushita Electric (Panasonic) and Toshiba today jointly announced the development of a content protection framework for Digital Versatile Disk (DVD)-Audio. This framework has been in development over the last 12 months as a result of discussions among the four technology companies and the world's five leading music companies: BMG, EMI, Sony Music Entertainment, Universal Music Group and Warner Music Group.

The public release of this music industry-supported copy protection framework is the last major step enabling DVD-Audio to be commercially introduced into the marketplace this year. DVD-Audio is the next generation music industry format based on the high capacity DVD technology. DVD-Audio offers significant improvements over present audio formats, including very high-quality multi-channel sound for home theater and automobile listening, artwork, liner notes and music videos.

In anticipation of the finalization of the DVD Forum's release of Version 1.0 of the DVD-Audio specification, several music companies encouraged the four computer and consumer electronics companies to define a framework for the copy protection of music released on DVD-Audio discs. The proposed framework was chosen to represent the best interests of content owners, consumers, PC systems integrators and hardware manufacturers in promoting the widespread support and development of products based on the DVD-Audio specification.

The new framework uses watermark and encryption technologies created or identified by the four technology companies to protect the music made available on the prerecorded DVD-Audio disc. The copy protected DVD-Audio discs can be played only on licensed players, in a way similar to that used for today's DVD-Video discs and players. The framework also includes a set of options which provide music industry content owners with the flexibility to address the needs of consumers as the market for DVD-Audio products develops.

"The framework was designed to satisfy both the music industry's copyright protection requirements and the consumers' need to protect their existing audio investments," said Alan Bell, IBM program director, digital media standards, and co-chairman of the Copy Protection Technical Working Group (CPTWG).

The framework provides consumers with the ability to make one digital copy, per recorder, of the original audio content for personal use at a sound-quality equal to CD-Audio or less. For example, a consumer who purchases a DVD-Audio disc for a home player would be able to make one copy -- on recordable CD, MiniDisc or DAT media -- for existing automobile or other personal music players. Content owners will have the option of allowing additional copies at various levels of quality, up to and including the full quality of the prerecorded DVD-Audio original.

IBM, Intel , Matsushita Electric (Panasonic) and Toshiba have all actively contributed to developing methods to protect digital entertainment content from unauthorized copying. For example, they have participated in the efforts to develop the DVD Content Scrambling System (CSS).
