Abstract

A system and method for managing digital rights. The method 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. The plurality of access rules 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

and

wherein the second usage rule of the retrieved required license comprises at least one of an indication of one or more users permitted play the selected encrypted digital media item, an indication of when the selected encrypted digital media item is permitted to be played, or a number of times the selected encrypted digital media item is permitted to be played by another user.

6. The home media server of claim 1, wherein the local license server is further to track usage of the retrieved required license.

7. The home media server of claim 1, wherein the local license server is further to identify the remote license server based on the second Universal Resource Identifier.

8. The home media server of claim 1, wherein to transmit the retrieved required license to the media rendering device comprises to transmit the retrieved required license to the media rendering device via a secure out-of-band transmission.

9. A machine-readable medium comprising a plurality of instructions stored thereon that in response to being executed by a home media server, cause the home media server to:

enumerate digital media items selectable by a user for local playback on a media rendering device communicatively coupled to the home media server via a local area network;

receive a selection associated with an encrypted digital media item from a control point communicatively coupled to the home media server;

transmit a first Universal Resource Identifier indicative of a media location at which the selected encrypted digital media item is located to the control point for transmission to the media rendering device;

receive a message from the control point to retrieve a license required to decrypt the selected encrypted digital media item, wherein the received message comprises a key identifier and a second Universal Resource Identifier indicative of a remote location of a remote license server communicatively coupled to the home media server and at which the required license is located;

retrieve the required license from the remote license server based on the key identifier and the second Universal Resource Identifier;

transmit a third Universal Resource Identifier to the control point, the third Universal Resource Identifier is indicative of a local location of the home media server at which the retrieved required license is located;

receive a request for the retrieved required license from the media rendering device based on the third Universal Resource Identifier; and

transmit the retrieved required license to the media rendering device to decrypt the selected encrypted digital media item based on one or more usage rules of the retrieved required license.

10. The machine-readable medium of claim 9, wherein to transmit the retrieved required license based on the one or more usage rules of the retrieved required license comprises to (i) determine whether the retrieved required license is valid based on the one or more usage rules and (ii) transmit the retrieved required license in response to a determination that the retrieved required license is valid or deny transmission of the retrieved required license to the media rendering device in response to a determination that the retrieved required license is invalid.
