An open media platform (OMP) notifies the subscriber terminals (ST) that the services it provides have changed and that the updated licenses should be retrieved. The STs then initiate a request to a license manager for the new licenses that are required. In response, the license manager requests from the OMP authentication/authorization of the ST and the license terms for the appropriate channels. The OMP authenticates the ST and determines the content ID's associated with the licenses that need to be issued. If authentication is successful, the appropriate C-ID's and terms are returned to the license server. When authorization and the license information are received from the OMP, the license manager generates the personalized licenses and delivers them to the originating ST to enable viewing of the protected content. |
