Display device. (2) The readout instruction circuit has an arithmetic circuit that calculates the difference between the azimuth of the antenna rotation position and the azimuth of the set search azimuth range, and instructs and displays the video signal readout in accordance with the azimuth of the calculated value. 1. A video display device according to claim (1) of the utility model registration, characterized in that the video display device comprises a circuit that outputs an azimuth signal. (3) The readout instruction circuit has an azimuth storage circuit that stores the antenna azimuth signal in synchronization with the video signal stored in the video signal storage circuit, and when the rotational azimuth position of the antenna is outside the set search azimuth range. A utility model registration claim comprising a circuit that outputs the stored predetermined antenna azimuth signal, instructs to read a video signal corresponding to the azimuth, and outputs an azimuth signal for display. Video display device as described in scope paragraph (1).
