The control unit analyzes the signal of broadcast contents received from a broadcast signal processor (22) and determines whether the signal contains adult content or not.;COPYRIGHT KIPO 2013;[Reference numerals] (21) Broadcast signal processor; (22) Broadcast signal processor; (23) Display unit; (24) Input unit; (25) Image acquisition unit; (26) Image processing unit; (27) Control unit; (28) Memory unit; (29) Communication unit
