<p>PURPOSE:To realize the two-way remote control system used easily by sending a control signal and a device operating state data signal between a control signal reception section and a data signal transmission section provided on each equipment and between a data signal reception section and a control signal transmission section provided on a remote controller. CONSTITUTION:A control signal reception section 6 and a data signal transmission section 7 are incorporated in the side of a tuner 1, and devices 1-5, a control signal reception section 6 in the tuner 1, a data signal transmission section 7, a tuner section 1' are connected by a bus line 8. Moreover, a remote controller 9 consists of a control signal transmission section 10, a data signal reception section 11, a display section 12 displaying the data signal reception content, a control section 13 and an operation section 14. Then the data signal transmission section 7 and the control signal reception section 6 make two-way communication by using the remote controller 9 and an infrared ray signal 15. Thus, the operating state of the stereo system is confirmed from a location apart from the device main body and the two-way remote control system offering ease of use is realized.</p> |
