摘要:
Methods, systems, and products are disclosed for controlling with rights objects delivery of broadcast encryption content for a network cluster from a content server outside the cluster that include receiving in the content server from a network device a key management block for the cluster, a unique data token for the cluster, and an encrypted cluster id; calculating a binding key for the cluster in dependence upon the key management block for the cluster, the unique data token for the cluster, and the encrypted cluster id; inserting a title key into a rights object defining rights for the broadcast encryption content; and sending the rights object to the cluster. In typical embodiments, the rights for content include an authorization for a play period and an authorized number of copies of the broadcast encryption content to devices outside the cluster.
