Abstract: A sync signal generator of a television receiver for use in a vehicle has a phase reset detector for gradually absorbing a phase fluctuation of an input sync signal which occurs due to a ghost phenomenon or a fading phenomenon and reducing a phase fluctuation. The sync signal generator provides a sync signal synchronized with an output signal of the phase reset signal detector. Thus, a stable sync signal without a sudden change in phase can be obtained although it is synchronized with the input sync signal.

Abstract: A diversity reception apparatus which has a plurality of antennas and in which one of the antennas having the best receiving condition is automatically selected and connected to a broadcasting signal receiver. The diversity reception apparatus has a feature in that after demodulated signals, obtained by the receiver respectively corresponding to the plurality of antennas, are converted into digital signals by an A/D converter, the best demodulated signal and the antenna corresponding thereto are selected by comparing the digital signals with each other, and that the width of a switch driving pulse from a switch driving pulse generator is made not more than 3 .mu.s.

Abstract: A sync generator which generates a reference horizontal synchronizing signal, a time difference detector which detects the time difference between the reference horizontal synchronizing signal and a horizontal synchronizing signal within a received television signal, and a variable delay circuit which responds to an output signal of the time difference detector to control the delay time and delay the received television signal are installed in a television receiver. When a plurality of horizontal synchronizing signals exist in one horizontal scanning period of the received television signal, the time difference between the horizontal synchronizing signal with the maximum amplitude and the reference horizontal synchronizing signal is detected, and the delay time of the received television signal is controlled in the variable delay circuit according to this time difference.
