Digital device control system using smart phone

A digital device control system using a smart phone capable of learning an infrared signal of a digital device, the system comprising:

• a remote control device provided together with the digital device, for transmitting a control command of a corresponding digital device as the infrared signal;
• an IR repeater provided with a microcomputer for receiving the infrared signal transmitted from the remote control device, capturing the infrared signal and transmitting the infrared signal to the smart phone through a wireless communication unit;
• the smart phone provided with an infrared signal learning unit for receiving the infrared signal transmitted from the IR repeater, matching the infrared signal to a corresponding control command, and storing the infrared signal, wherein
• the IR repeater includes:
• a learning signal reception unit configured as an infrared ray receiver (IR_Receiver) being activated when the IR repeater is set to a learning mode and receiving the infrared signal transmitted from the remote control device;
• a microcomputer functioning as a control unit in charge of general control of the IR repeater and, in addition, capturing and storing the infrared signal as is received by the learning signal reception unit and transmitting the infrared signal to the smart phone;
• and
• a wireless communication unit configured as a communication module for transmitting and receiving data to and from the smart phone through a wireless communication network.

A digital device control system using a smart phone, the system comprising:

• the smart phone including a driving signal creation unit for creating a driving signal for controlling a digital device by handling a button displayed on a display means by activating a digital device control application and a driving signal communication unit for transmitting the driving signal of the digital device created by the driving signal creation unit through a wireless communication unit;
• a relay home server for receiving the driving signal transmitted from the smart phone of outside and transmitting the driving signal to an IR repeater installed inside of a room;
• and
• the IR repeater including a driving signal reception unit for receiving the driving signal transmitted from the smart phone or the relay home server, an infrared signal generation unit for generating an infrared signal corresponding to a custom code and a control command of the digital device, which configure the received driving signal, an infrared signal transmission unit for transmitting the infrared signal toward the digital device, and a wireless communication unit formed as a gateway for receiving the driving signal.
