Microsoft and AT&T announce
collaborative effort to use Microsoft PlayReady content access and protection technology
to enable shared content and converged entertainment experiences across AT&T’s TV,
broadband and wireless services. As part of this collaboration, Microsoft intends
to add support for PlayReady into its Microsoft Mediaroom IPTV software platform,
enabling access to PlayReady-based content through AT&T U-verse TV set-top boxes.

PlayReady is designed to enable digital entertainment services across devices and
software applications, with a specific focus on meeting the needs of mobile and network
operators, service providers and device manufacturers. PlayReady supports a broad
range of business models that can be applied to almost any type of digital content
and a wide range of formats. PlayReady also provides features such as service domains
and embedded licenses specifically designed to make it easy for consumers to enjoy
content on all their registered devices without the need of an active connection.
