A television receiver is connected to a smart antenna, and comprises: a tuner for receiving, and measuring signal intensity of, a television signal; an OSD superimposer for superimposing, on the television signal, an image indicating an active receiving direction of the antenna; and a microprocessor for outputting, to the antenna and respective elements of the television receiver, various signals including a receiving direction control signal. Based on the signal intensity, the microprocessor determines the active receiving direction of the antenna, and outputs a receiving direction control signal to the antenna, and further outputs a signal indicating the active receiving direction of the antenna to the OSD superimposer which is connected to a monitor for image display. The antenna comprises: a control unit for making active one receiving direction commanded by the receiving direction control signal; and a display for displaying the commanded receiving direction. A user can easily recognize the receiving direction of the antenna, either at the television receiver site or the antenna site.
