Microsoft Licenses Analog Anti-rip Technology
CD copy-protection specialist Macrovision is to work with Microsoft to ensure their respective DRM and anti-rip technologies are interoperable, the two companies said this week. Sounds straightforward enough, but the deal runs deeper. Microsoft agreed to license a number of Macrovision’s patents, in particular those relating to analogue copy protection technology and more recent extensions to that system that cover video-on-demand, pay-per-view content and support for the US ‘broadcast flag’, which determines whether consumers will be able to record digital TV broadcasts.
