[Background Art] With the advancement of information media equipment,
As AV systems centered on television receivers became widespread, it became necessary to use as many remote control transmitters as there were components, and it became possible to use remote control transmitters for television receivers to remotely control other video equipment, such as VTRs. Some do, but
Compatibility with other companies' video equipment was not sufficient. In other words, as a remote control transmitter that is compatible with other companies' video equipment, the remote control signal receiving section of the remote control transmitter in storage mode receives the remote control signal of the other company's remote control transmitter and makes it correspond to the operation keys of the own device. The control code was stored in the non-volatile memory within the machine, and by operating the same key, the control code stored in the non-volatile memory was converted to a remote control signal and output, thereby remotely controlling other companies' equipment.
