Abstract:
1. A system for controlling a motion using time synchronization between a picture and the motion, comprising: a picture server configured to show the picture in a facility of showing pictures and transmit a time code corresponding to the picture; a central server configured to transmit a reference time of the picture by analyzing the time code received from the picture server; and a motion controlling device configured to prestore a motion code corresponding to the reference time of the picture before showing the picture and control the motion of an actuator according to the prestored motion code when the picture showing starts, a current motion driving time being synchronized with the received reference time of the picture by comparing the current motion driving time with the reference time of the picture received from the central server, wherein the motion controlling device resets the current motion driving time according to the received reference time of the picture when a time difference between the received reference time of the picture and the current motion driving time is greater than a predetermined threshold, and wherein when the motion controlling device fails to receive the reference time of the picture or when the time difference between the received referenced time of the picture and the current motion driving time is less than or equal to the predetermined threshold, a clock of the motion controlling device determines the current motion driving time.
