The present invention is disclosed by that the series connected capacitive impedance and inductive impedance are powered by a pulsed power, thereby to produce the bi-directional divided power in series resonance at each impedance, and be rectified by a rectifier device to provide DC power output to drive the unidirectional conducting light emitting diode. Based on the control signal CS, a TS header processing section 16 specifies a TS header added to a payload of an I picture from the transport stream TS, and changes a value of a reserved bit in the TS header from 0 to 1. The pointers are saved to persistent storage at the earlier time. At least one propeller is mounted on the top of the body including at least two rotating blades.
