Abstract
A remote control system enables simplified programming of new remote control transmission data of an electronic apparatus which a user wants to remotely control. A plurality of electronic apparatuses are remote controlled by using a single common use remote control transmitter and by converting an infrared signal from an exclusive use remote control transmitter belonging to an electronic apparatus into another remote control transmitter data at a remote control signal analysis/output unit. The data is output as a magnetic signal, the magnetic signal is received, the signal is converted into new remote control transmitter data and the converted data is stored in a nonvolatile memory device.
