DIGITAL DEVICE CONTROL SYSTEM USING SMART PHONE
First Claim
1. A digital device control system using a smart phone, the system comprising:
- the smart phone having an application of a remote control function;
a digital device of which on/off of a power supply, channel or volume is controlled according to an infrared; and
an IR repeater functioning as a central control unit connected to the smart phone through Bluetooth or Wi-Fi communication and, if a signal of the smart phone is received, transmitting the infrared signal to the digital device, whereinthe IR repeater includes;
a communication unit for wirelessly communicating with the smart phone through the Bluetooth or Wi-Fi communication;
a code storage unit for storing information on an electronic product and a manufacturer corresponding to a custom code;
a plurality of infrared ray transmission and reception units including a plurality of LEDs for expanding a transmission angle to a range of 60°
to 360° and
transmitting the infrared signal; and
a microcomputer for controlling the digital device control system to separate and detect a custom code of the digital device included in the signal of the smart phone received through the communication unit, compare a custom code in the code storage unit with the custom code of the digital device, and transmit the infrared signal for controlling the digital device through the infrared ray transmission and reception unit if the custom codes are matched.

Abstract
There is provided a digital device control system using a smart phone, including a smart phone having an application of a remote control function, a digital device of which on/off of a power supply, channel or volume is controlled according to a signal received from the smart phone, and an IR repeater functioning as a central control unit connected to the smart phone through Bluetooth or Wi-Fi communication and connected to the digital device through a plurality of infrared ray communications in order to remotely control the digital device, and therefore, the digital device can be controlled using the smart phone instead of a remote controller. In addition, since a plurality of LEDs capable of performing infrared ray communication is included in the IR repeater so as to transmit and receive an infrared signal of a wide range, a digital device desired to be controlled can be remotely controlled even when the digital device is placed at a far distance or at a blind spot in a room, and a plurality of digital devices can be controlled simultaneously.
