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.
