PURPOSE:To completely suppress the generation of a malfunction in an unspecified remote controlled device by transmitting plural different control instructions which are encoded in series and successively transmitting the same control instruction more than two times. CONSTITUTION:After the same control data is transmitted three times, when a programmable timer 8 completes the third counting, the data corresponding to a 1 word period T is preset only to the programmable timer 8 and the com pletion of the counting is waited for. According to the waiting for the time, as shown in the drawing, the control data having a silence part N corresponding to the 1 word period T is formed next to the three same data D1, D1, D1, and transmitted. Similarly, the second the fourth data having the silence part in the vicinity is formed and sequentially transmitted. According to the presence of this silence part, the completion of the transmission of one control instruction an be effectively discriminated. Accordingly, if the remote controlled device is provided with a toggle input circuit or a successive sound volume adjusting circuit or the like, all the control instruction can be effectively performed. |
