Patent ID: 8819838

Claim:
A method in a multimedia device communicably coupled to a network, the method comprising: obtaining protected content that originates in a first DRM system, the protected content having a limited exercisable right associated therewith, obtaining an extension of the limited exercisable right when a condition is satisfied, the condition is satisfied upon entry of the multimedia device into a second DRM system that is different than the first DRM system from which the protected content originates, and the extension of the limited exercisable right obtained from an entity other than the multimedia device, transmitting a hash of the protected content to the entity from which the extension is obtained upon entry into the second DRM system, receiving the extension from an anomaly detector coupled to the first DRM system and the second DRM system, which is adapted for detecting any anomaly in the protected content in response to transmitting the hash, wherein the anomaly detector assigns the extension to the protected content after determining that the protected content is eligible for rights extension based upon a review of the hash of protected content received from the multimedia device, and associating the extension with the protected content.
