Windows Media digital rights management (DRM) is a flexible platform that makes it
possible to protect and securely deliver a la carte and subscription content for playback
on a computer, portable device, or network device connected to an IP network. The latest
release of Windows Media DRM enables new scenarios for consumers and provides content
owners with new outlets for their content. The following sample scenarios show how an
already robust platform now offers even greater value.
Business Scenarios
Subscription Services
Today, consumers can download thousands of tracks to their computers from a variety of
content services for a low monthly subscription fee. However, this subscription content
hasn't been transferable to portable devices. Windows Media DRM 10 solves this issue by
providing platform technology that allows content services to deliver content with
expanded business rules and enables devices to support those business rules. This means
that subscription content can flow to devices, making subscriptions more valuable to
consumers.
For instance, consumers will be able to download a virtually unlimited
number of tracks through their subscription, play them as often as desired, and transfer
them to any device that supports Windows Media DRM 10. These tracks will be linked to
licenses that have start and end dates. At the end of the billing period, the consumer
connects to the content service provider and licenses are automatically refreshed provided
the consumer has paid the fee. Otherwise, the licenses simply expire.
Purchase and Download Single Tracks
In this scenario, consumers purchase and download tracks protected with Windows Media DRM
from content service providers on a per-track basis as opposed to the subscription model.
This remains a very popular scenario and a wide variety of service providers use Windows
Media DRM to protect such content today.
Rental Services
Many consumers download movies on a rental basis over the Internet to their computers.
Windows Media DRM makes this possible by supporting time-based licenses. This means that
movie download services can create licenses that satisfy consumer viewing habits while
ensuring that the content is used in the way the content owners intended. For instance,
consumers might rent a movie that allows them to begin viewing it anytime within 30 days,
and for 24 hours once they start playing it.
Windows Media DRM 10 enables this
content to be transferred to portable devices that support video playback, such as
Portable Media Center devices.
Video-on-Demand or Pay-Per-View Movies
Windows Media DRM has long supported pay-per-view scenarios for playback on a computer.
Windows Media DRM 10 extends this capability to set-top boxes, so content can be viewed
and licensed over a cable network in addition to being played back through a computer.
One File, Different Licenses
With Windows Media DRM, a retail Web site can offer consumers a choice of licenses when
purchasing content. For example, for a small fee, consumers can play the song for one
month. For a larger fee, they can play the song forever and transfer the song to a
portable device. If they choose the latter, Windows Media Rights Manager, the license
server of Windows Media DRM, issues a license to them with no expiration date that also
includes the right to play the file on a portable audio device.
Company Presentations: Protection of Sensitive Material
A company can protect sensitive digital media assets, such as recorded company
presentations, by using Windows Media DRM. For example, employees that are unable to
attend a company meeting can view the taped presentation at a later time. Because the
company doesn't want the information to leak out to its competitors, it has protected the
streamed content by using Windows Media DRM. When the employees select to view the
presentation from their computers, a one-time license for the content is issued silently,
and the video begins streaming.
Distance Learning
A university can save videos of lectures and discussions and encrypt them by using Windows
Media DRM so they can be streamed or downloaded to students' computers after the
acquisition of a license. The student logs in, and a license is sent to her computer. The
university uses the license as an attendance record and also for billing purposes.
