发明名称 Technique for providing security measures for communications device connectable to a communications network
摘要 A user may purchase in a retail outlet a host device for receiving cable services. The cable operator needs to provide a point-of-deployment (POD) module for insertion into the host device to realize out-of-band communications, and provide conditional access to premium subscription channels. Security measures are implemented to detect removal of the host device from its connection to a broadband communications system. If its removal is unauthorized, the service area in which the host device is located may be identified when it is reconnected to the system. In addition, a transmission device in the host device may be activated to transmit detectable signals to help recover the host device.
