Abstract:
1. A signal transmission system, comprising: a receiving device; and a transmitting device including a superimposition portion that superimposes at least one synchronizing signal on at least one video signal among a plurality of video signals, and outputs the synchronizing signal and the video signal as a superimposition signal to a receiving device, the receiving device including: a separation portion that separates the superimposition signal into the synchronizing signal and the video signal; a first delay portion that delays the separated video signal, an amount of delay of the separated video signal being adjustable; a second delay portion that delays the separated synchronizing signal, an amount of delay of the separated synchronizing signal being adjustable; a first adjustment portion that adjusts the amount of delay of the separated video signal to another video signal; and a second adjustment portion that adjusts the amount of delay of the separated synchronizing signal, wherein the amount of delay of the separated synchronizing signal is adjusted so as to be identical with the amount of delay of the separated video signal.
