Andy Tai writes: "This InteractiveWeek article describes how Microsoft, without much public attetion, has built multimedia content protection technology into Windows, thus encouraging the movie and music industries to adapt the Windows Media formats for their content. Microsoft's offering is not very different from other DRM (Digital Rights Management) technologies, but MS has the advangage of being able to place it in the OS, which gives it credibility in the eyes of content providers. 'What's novel is that it's built directly into (Windows Media) that is quickly gaining ground on its own, and that the two (DRM and media) technologies are inextricably linked. The technologies, in turn, are being set deeply into the Windows operating system. Other technologies being built into Windows further boost content-protection features, such as the so-called Secure Audio Path, which scrambles output from a computer sound card so that music streams can't be tapped and copied at that point.'"
