IBM, Intel, Matsushita Electric and Toshiba are jointly developing a copy protection framework for Digital Versatile Disk (DVD) Audio that has the backing of music industry heavyweights.
The framework has been developed over the last 12 months, following discussions with music companies BMG, EMI, Sony Music Entertainment, Universal Music Group and Warner Music Group. It is expected to be commercially available this year.
DVD Audio is the next generation industry format based on DVD technology. The significant improvements it will offer include high quality multi-channel sound for home theatre, in car stereo and music videos.
The copy protection framework for DVD Audio will use watermark and encryption technologies to protect music copyright on pre-recorded DVD Audio discs. Consumers will only be able to play the discs on licensed players, much the same as DVD discs and players today.
The framework includes the ability to make one digital copy per DVD Audio recorder of the original disc for personal use on recordable CD, Minidisc or Dat Media.
