Abstract

A system and method for managing digital rights includes receiving a Universal Resource Identifier (URI). The URI is used to identify a location for a user selected digital media item. The digital media item is to be played in a local area network (LAN). The selected digital media item is retrieved from a content server over a network connection. If the selected digital media item is encrypted, a license to decrypt the selected media item is obtained. Access to the license is based on a plurality of access rules, which are based on the terms of the license. The plurality of access rules may also include personal owner rules. If a request for the license adheres to the access rules, the license is received via a secure out of band transfer and the selected digital media item is decrypted for playback via one or more media rendering devices.

Claims

1. A system for managing digital rights media, comprising:

a home network coupled to a wide area network, the home network including a home media server, the home media server containing references to encrypted digital media items, the home media server including a local license server, the local license server including a plurality of licenses for the encrypted digital media items, wherein the local license server manages distribution of the plurality of licenses based on key identification and distribution access rules for each of the licenses; and

a media renderer, coupled to the home media server, to retrieve, decrypt and play the encrypted digital media items, wherein the media renderer retrieves the encrypted digital media items from the wide area network and wherein the encrypted digital media items are decrypted using a key supplied by the licenses for the encrypted digital media items.

2. The system of claim 1, wherein the home network further comprises:

one or more media rendering devices coupled to the media renderer to enable playback of the encrypted digital media items to a user; and

a controller, wirelessly coupled to each of the home media server, the media renderer, and the media rendering devices to control the home network.

3. The system of claim 2, wherein the one or more media rendering devices comprises at least one of a compact disk (CD) player, a MPEG-audio layer 3 (MP3) player, a Windows Media Audio (WMA) player, a digital versatile disc (DVD) player, a television (TV), a video digital recorder (VDR), and a home theater system.

4. The system of claim 2, wherein the media renderer to distribute the encrypted digital media items to the one or more media rendering devices.

5. The system of claim 2, wherein the media renderer further to extract unencrypted meta data from the encrypted digital media items corresponding to the licenses, the unencrypted meta data including a key identifier and a license Universal Resource Identifier (URI) for each of the plurality of licenses, the key identifier identifies a particular license and the license URI identifies where the particular license can be found.

6. The system of claim 5, wherein the media renderer to send the key identifier and the license URI for the particular license to the controller, the controller further to determine whether the particular license is available from the local license server.

7. The system of claim 6, wherein the local license server further to:

(i) retrieve the particular license from a license server on the wide area network using the key identifier and the license URI in response to the controller determining that the particular license is not available from the local license server; and

(ii) send the particular license retrieved to the media renderer.

8. The system of claim 6, wherein the local license server further to send the particular license to the media renderer in response to the controller determining that the particular license is available from the local license server.

9. The system of claim 1, wherein the licenses for the encrypted digital media items not located within the local license server are retrieved from a license server on the wide area network using the local license server.

10. The system of claim 1, wherein the local license server manages the distribution of each of the licenses by not releasing a license corresponding to an encrypted digital media item if a request for the license does not adhere to the access rules for the license, wherein the access rules for the license are based on terms of the license.

11. The system of claim 10, wherein the access rules include at least one of a number of times the encrypted digital media item is to be played, a number of media rendering devices the encrypted digital media item may be played on at one time, an expiration of the license, and a length of time a user may play the encrypted digital media item.

12. The system of claim 1, wherein the access rules are based on terms of the licenses and personal owner rules regarding playing the encrypted digital media items, wherein the personal owner rules regarding playing an encrypted digital media item include at least one of an indication of who can play the encrypted digital media item, an indication of when the encrypted digital media item can be played, and an indication as to the number of times the encrypted digital media item can be played by certain individuals.
