Transmitter for remote control system and method of remotely controlling a plurality of operations on a plurality of electronic devices

摘要

A transmitter for a remote control system for controlling a plurality of operations on a plurality of electronic devices. An external input unit (18) generates a selection signal in response to a user's manipulation of a plurality of keys (2) thereon and transmits this selection signal to a control unit (30). The control unit (30) by use of a signal processor retrieves information from a correspondence table ( 4) which links the particular selection signal to a particular operation on a particular electronic device and generates a transmission signal in response thereto. An outputting unit (12) receives the transmission signal and outputs a remote control signal which causes the selected electronic device to perform the selected operation. The transmitter includes a display unit (22) to display a message in response to a display signal generated by the control unit (30).
