Abstract:
1. An analog television broadcast receiver with a screen for display and connected to a multi-directional antenna having multiple receiving directions, the analog television broadcast receiver comprising: a channel setting unit for setting channels, to be received by the multi-directional antenna, at channels each designated by a user at the time of a channel registration; a receiving direction change unit for sequentially changing and setting the receiving directions of the multi-directional antenna for each channel set by the channel setting unit; a received signal intensity storage unit for temporarily storing intensities of an analog television broadcast signal for each channel in respective receiving directions of the multi-directional antenna as changed by the receiving direction change unit; a receiving direction determination unit for determining a best receiving direction(s) for each channel on the basis of the intensities of the analog television broadcast signal stored in the received signal intensity storage unit; a receiving direction storage unit for storing the best receiving direction(s) for the each channel determined by the receiving direction determination unit; and a channel up/down operation unit for selecting a channel by forward or backward channel selection from channels displayed on the screen of the analog television broadcast receiver, wherein: a best receiving direction(s) for each channel is or are registered at the time of a channel registration by the channel setting unit, the receiving direction change unit, the received signal intensity storage unit, the receiving direction determination unit and the receiving direction storage unit; the receiving direction determination unit determines all such receiving direction(s) as the best receiving direction(s) for the each channel, if there are one or multiple receiving directions for each channel to give higher intensities of the analog television broadcast signal than a predetermined threshold intensity; the receiving direction storage unit stores the best receiving direction(s), determined by the receiving direction determination unit, as a combination(s) of each channel and the best receiving direction(s) associated with the each channel; the receiving direction change unit makes active the best receiving direction(s) of the selected channel registered, when the user selects a channel after the channel registration, so as to receive an analog television broadcast signal in the best registered receiving direction(s) for the channel; and the best receiving direction(s) in the combination(s) of the each channel and the best receiving direction(s) associated with the each channel are changed by the user operating the channel up/down operation unit.
