KR970025258A - Remote controller using ROM-CARD - Google Patents

Abstract

The present invention relates to a remote controller using a ROM card (ROM-CARD), and in addition to the ROM existing in the existing remote control, an expansion ROM storing driving instructions for a desired A / V device is provided in a predetermined portion of the remote controller. Mounted on the frame (B), using the selector switch on the keypad to select the desired A / V device, and then pressing a key to perform the desired operation, the parallel operation corresponding to the desired operation from the ROM and expansion ROM. The drive command is drawn out and provided to the P / S converter, respectively, and the parallel drive command from the ROM or the extension ROM is selectively converted into the serial drive command based on the selection signal from the keypad, and converted into the infrared signal through the converter. And then it is transmitted through the light emitting unit, it is possible to control the operation of a plurality of A / V / equipment and office equipment in addition to the existing functions of the remote control by mounting the expansion ROM to the remote control , Is a so it is possible to prevent an increase in production costs is generated By making the FLAHZS each device can be made more convenient use of the user.
