Patent ID: 8689314

Claim:
A Downloadable Conditional Access System (DCAS) provisioning server (DPS) in a network supporting a host that moves from a network of a first authentication proxy server to a network of a second authentication proxy server, the DPS comprising: a mapping information receiver to receive, from the second authentication proxy server, mapping information between the second authentication proxy server and a secure micro of the host, wherein the secure micro is used for the host as the host moves from the network of the first authentication proxy server to the network of the second authentication proxy server; and an instruction unit to, in response to receiving the mapping information, instruct a conditional access system (CAS) server to transmit an entitlement management message to the network of the second authentication proxy server without transmitting the entitlement management message to the network of the first authentication proxy server, and wherein the entitlement management message is configured to support the host while the host is in either the network of the first authentication proxy server or the network of the second authentication proxy server.
