PROBLEM TO BE SOLVED: To judge a remote control transmitter for outputting a remote control signal for the first time by simultaneously transmitting remote control signals from plural remote control transmitters after reset, and continuously detecting the ID information of the remote control signals received later during a monitor period when the remote control signals are overlapped and ID information cannot be detected. SOLUTION: When an incoming judging part 12 detects the rising of a BUSY signal, it judges that this is reset, and informs each player by a speaker 17 and a display part 18. Whether or not any remote control signal is included in an input signal inputted from a receiving part 11 is judged according to whether or not a pulse signal demodulated by a demodulating part 13 is one part of a primary modulated signal generated by a transmission signal generating part 3. When it is judged that the remote control signal is included, this remote control signal is further secondary demodulated by the demodulating part 13, and an ID code is decoded from the secondary demodulated remote control signal. Then, a remote control transmitter 1 is judged from the decoded ID information. |
