A voice-signal/remote-control-pulse converter (30) receives a voice signal (S) by means of infrared rays (RV) from a remote control transmitter, and then performs voice recognition. An item of control information indicated by a recognized word (W) is converted into a control code (C) in the same format as that of a control code indicated by a remote control signal (RK). The control codes are entered into a remote control pulse selector (23) as respective remote control pulses P1 and P2 in the common format. The remote control pulse selector (23) enters exclusively one of the remote control pulses P1 and P2 into a remote control pulse decoder (24) in response to a remote-control-pulse switching signal (N).
