A television receiver is connected to a multi-directional antenna having multiple receiving directions for receiving a television signal by making one receiving direction active, and comprises a clock, a tuner, a memory for storing a receiving direction table having content containing channel numbers and a best receiving direction, and a microprocessor for controlling the receiver. Based on the time measured by the clock, the microprocessor renews the content of the table at a preset time, and outputs, to the antenna, a control signal to command a receiving direction for receiving one channel based on the renewed content of the table. The receiver can properly adapt to the variations in time of the receiving conditions of terrestrial broadcasts based on the renewed content of the table, and can automatically renew the content of the table in a time zone when a user does not view a television program.
