ABSTRACT:
An analog TV broadcast receiver connected to a multi-directional antenna has a receiving direction counter for a channel which is set at an initial receiving direction to measure intensity of a TV broadcast signal in the initial receiving direction, when a channel registration in the TV broadcast receiver starts. The measured intensity, if higher than a threshold, is registered in a channel map. The receiving direction counter is sequentially incremented to measure the intensities in all receiving directions. All the measured intensities higher than the threshold are registered in the channel map as best receiving directions. A user can delete one or more of the registered best receiving directions by viewing images on a screen of the TV receiver that are given by the registered best receiving directions. It can solve a problem that a receiving direction which a user considers to give an undesired image remains registered.
