Remote control device and method

摘要

The present invention relates to a method of controlling a device remotely and includes: transmitting a device selecting signal; receiving a response signal from a device to be controlled that receives the device selecting signal; identifying the device to be controlled by using the response signal; changing at least one of an angle of beam spread and direction of the device selecting signal if the identified device to be controlled is two or more in number; and generating a remote control signal by using device control information corresponding to the identified device to be controlled and transmitting the generated signal to the device to be controlled.

1. A remote control method, comprising:
transmitting a device selecting signal; receiving a response signal from a target device that is to be controlled and that receives the device selecting signal; identifying the target device based on the response signal; changing at least one of an angle of beam spread and a direction of the device selecting signal, when a plurality of target devices to be controlled are identified; and generating a remote control signal based on device control information corresponding to the identified target device, and transmitting the remote control signal to the target device, wherein the step of changing at least one of an angle of beam spread and a direction of the device selecting signal comprises: reducing the angle of beam spread of the device selecting signal at a predetermined interval; requesting a device that receives the device selecting signal to transmit the response signal; and reducing the angle of beam spread of the device selecting signal until one of the plurality of target devices is selected.
