<p>PROBLEM TO BE SOLVED: To suppress the time lag between a display image by a terminal apparatus and output voice by an on-vehicle voice output unit as much as possible, in an on-vehicle system to which the terminal apparatus capable of image display is freely detachable.SOLUTION: An on-vehicle system (20) comprises a vehicle side apparatus (30), terminal apparatuses (40, 50), and an on-vehicle voice output unit (203). The vehicle side apparatus is fixed to an inner package portion of a vehicle. The terminal apparatus performs image display by short-distance radio communication with the vehicle side apparatus in a state where the own apparatus is set to the vehicle side apparatus detachably. The vehicle side apparatus comprises a delay state acquisition unit (3011) and a time lag suppression processing unit (3012). The delay state acquisition unit acquires a delay state in transmission/reception of a video signal by the short-distance radio communication. The time lag suppression processing unit performs suppression processing for the time lag between a display image and output voice on the basis of the acquired delay state.</p> |
