Abstract: A broadcast reception device is provided. The broadcast reception device includes a communication interface unit receiving, from a CAM, a first data unit including a request for diagnostic information for representing a status of the broadcast reception device; and a control unit generating a second data unit including a reply to the first data unit to transmit the second data unit to the CAM through the communication interface unit, wherein the second data unit includes information representing that the broadcast reception device does not implement displaying of a diagnostic information related screen.
