Abstract

A method and system for managing use of items having usage rights associated therewith including a point of capture system adapted to generate content of a future event when the event occurs, a content distributor adapted to generate a rights label having usage rights associated with content of the future event before the content is created, the rights label having a distribution key for encrypting the content as the content is generated, the distribution key being encrypted with a public key. The system also includes a license server adapted to generate a license associate with the content from the rights label before the content is generated, the license including the distribution key encrypted with the public key, and a content distributor adapted to distribute the license before the content is generated.
