Abstract
A television tuner that receives a television signal using a smart antenna includes a rescan unit that executes rescan; that is: that when an instruction that instructs direct selection of a reception channel on which a television signal is currently received is issued during reception of a television broadcast service, causes an antenna control section to vary or control the receiving direction of the smart antenna and causes a signal state detector section to detect the states of signals sampled in all receiving directions; and that if the state of a signal detected by the signal state detector section agrees with a predetermined signal state, preserves the receiving direction of the smart antenna in which the signal is sampled. Consequently, rescan can be executed for all the receiving directions of the smart antenna by performing a simple manipulation.
