Coalition Aims To Limit Digital Copies

Music and technology companies publish specifications for portable digital-music players.

Music fans will be able to store only a limited number of digital copies of a song on their computers, under guidelines for copyright-protected music made public Tuesday (July 13) by a coalition of music and technology companies known as the Secure Digital Music Initiative. While content creators, such as record companies, will be able to set their own limits on copies, the default limit will be four. The coalition's guidelines are aimed at portable digital-music devices such as the Rio MP3 player. SDMI is trying to develop industry-wide standards to thwart online piracy while encouraging record companies to release music for sale by download.
