KR970009451A - Remote control - Google Patents

Abstract

The present invention relates to a remote control device, and to a remote control device for remotely controlling various home appliances having a remote control receiver at a distance of more than a visible distance.

In general, the remote control function can be used only within the visible distance that the infrared signal of the remote control transmitter can reach the controlled device, and in order to control the controlled device using the remote control transmitter, the user must operate the remote control transmitter. If the user is located at a distance greater than the visible distance (for example, when the user is out of the house), there is a problem that the remote control function cannot be used.

The remote control apparatus according to the present invention can remotely control the controlled devices having the remote control function even when the user is located at a remote distance beyond the visible distance where the user cannot use the remote control function. Can be controlled to provide convenience in using the remote control function.
