A timing signal generating part generates a timing signal at a preceding timing preceding a switchover timing between a video signal for the left eye and a video signal for the right eye by a predetermined offset time. When a transmitting time adjustment cause is detected by an adjustment cause detecting part at a generating timing of the timing signal, a timing signal transmitting part generates an adjusted timing signal by adjusting the transmitting time of the timing signal by a predetermined adjustment time at a transmitting time at which the transmitting time adjustment cause does not exist, adds adjustment time information including the information on the adjustment time to the adjusted timing signal, and wirelessly transmits the resultant signal to the wireless communication apparatus.
