Patent ID: 8059212

Claim:
A television receiver comprising: at least two tuner units that respectively connect to multidirectional antennas capable of electrically switching a directivity of a receiving radio wave and select a television broadcast signal corresponding to a channel selected by a user, an antenna direction searching section that searches all azimuthal directions while serially switching a directivity direction of the multidirectional antenna and that sets an optimum receive direction into the multidirectional antenna; an auto-scanning section that determines in units of each channel whether the optimum receive direction has been set by the antenna direction searching section into the multidirectional antenna and that, when a predetermined signal has been able to be demultiplexed from a television broadcast signal on a channel corresponding to the multidirectional antenna set to the optimum receive direction among respective channels, stores the optimum receive direction of the multidirectional antenna on the channel into a channel table, a channel selection section that, in the event of channel selection, sets a frequency corresponding to a selected channel into a predetermined tuner unit, acquires an optimum receive direction of the multidirectional antenna from the channel table, and sets the optimum receive direction into the multidirectional antenna; and an optimum direction updating section that operates, while one of the tuner unit is not in use, to update an optimum receive direction of the multidirectional antenna on a channel other than a channel selected in the other tuner unit, wherein the optimum direction updating section serially updates optimum receive directions of the multidirectional antenna on the respective channels in parallel with channel selection operations of the channel selection section, the optimum receive directions being stored in the channel table.
