Subscription Services:

Consumers will be able to download a virtually unlimited number of tracks through their subscription, and play them as often as desired. 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:

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.

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.

Video-on-Demand or Pay-Per-View Movies:

Pay to view or listen on a single track or video.

Live DRM: Enjoying Concerts and Sports Events in Real Time:

With Windows Media DRM, content owners can deliver protected live digital media content-such as news, rock concerts, or major sporting events-over the Internet as the events are happening, without requiring that the content first be batched and saved. For example, a music label could offer consumers a customizable concert package with a choice of upcoming performances. After the transaction is complete, consumers can watch the protected live performances streamed over the Internet as they occur.

Preview and Purchase Content:

A retail Web site can offer consumers the option to preview songs before buying them. For example, consumers are allowed to download any song and play it two times in exchange for registering with the service. The third time consumers attempt to listen to the song, they are taken directly to the retailer's Web site where they are given instructions on how to purchase the song. In this scenario, content owners are able to promote their recording artists and albums on the Internet while cutting down on marketing costs and using the registration information to strengthen their mailing list.

One File, Different Licenses:

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.
