摘要:
A system, apparatus, and method are directed towards managing entitlement/right revocation and delivery to be performed within a non-addressable media network. Such networks may include for example a client device behind a network address translation (NAT) device, employs non-addressable satellite components, or so forth. A server notifies clients that entitlements, revocations, or the like are available by sending a request for communications with the client. The client initiates a connection to receive the entitlements, or the like, and then disconnects from the server. If the client fails to initiate a connection, the server may continue to send a request for a connection, or even change encryption keys to the content to prevent access by the client. In one embodiment, failure to receive an acknowledgement response from the server of a connection with the client, or from the client, may result in invocation of a revocation failure action.
