BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-way home network system. Specifically, the operation of home appliances or various devices is controlled remotely or at home using a wired or wireless Internet, and whether or not the operation of various electronic products is performed using a video and audio compression technology. The present invention relates to a two-way home network system based on image compression technology for viewing through the Internet.

In general, a home automation system refers to a system for automatically controlling various devices such as electronic products in a home by using a control device such as a home server to provide more convenience and comfort to residential life.

In addition, until now, a number of technologies for realizing a home automation system have been proposed, and recently, a method of freely controlling a home automation system by a user using a mobile communication terminal or the Internet has been posted.

However, the conventional home automation system is a semi-permanent system that does not need to change settings for a certain period of time once installed such as door control, power control of lighting devices, and heating / cooling temperature control using RF (Radio Frequency) method. In general, electronic appliances such as TV, video, washing machine, refrigerator, and air conditioner are mainly focused on wireless remote control using IR (Infra Red) method. There was a practical difficulty.

In addition, the wireless remote controller mainly used until now has been configured to transmit and receive ultraviolet rays having respective identification data codes, and unlike ultraviolet rays having a transmissive property, infrared rays have reflection characteristics, so that a conventional remote controller operator emits light of the remote controller. It is inconvenient to operate the remote control at a position where the space view between the unit and the light receiving unit of the electronic product is secured.

Due to these characteristics, it is almost difficult to control the electronics in the wall or other barriers in the home, and it is impossible to control according to the site situation with the conventional remote controller which performs only one direction control. It is a situation that there is a difficulty in moving to a device to be controlled directly and giving a command without blocking other objects at a short distance.

In addition, the infrared identification code adopted for each electronic product has a remote control having a plurality of different uses in the home, causing inconvenience to find the remote control according to the situation.

In order to solve such inconvenience, recently integrated remote controllers incorporating respective infrared identification codes have been introduced. However, since the integrated remote controller also adopts an infrared ray receiving type, there is still a problem of reflection due to space blocking. If another electronic product is added to the integrated remote controller, which is outside the range of the preset infrared code, the update operation such as adding a control function or changing the code is practically impossible.

According to Patent Publication No. 2004-85822 "Home Automation System Using IR and RF Integrated Remote Control Module and Its Method" filed by the present applicant to solve this problem, the wired / wireless internet module is embedded as shown in FIG. A wired / wireless computer terminal (400, 500) for performing a wired / wireless data communication process through the Internet, and a program for issuing a remote control and monitoring command for the home automation system by an operator's selective operation; and a remote control of a home automation system. And an RF transceiver 10 configured to receive and demodulate predetermined RF data for monitoring, convert the digital data into digital data, or modulate the applied digital data into predetermined RF data and transmit the same to various devices or systems using an RF scheme. By receiving the digital data and performing IR (Infrared) modulation Infrared (IR) transceiver 30 for generating an optical signal that can be transmitted to each electronic product using the IR method to transmit to each device or system, and digitally converted and transmitted from the RF transceiver If the data is RF data, the RF transceiver processes RF transmission and reception, and if the digital data converted and transmitted by the RF transceiver is IR data, digital data is applied to the infrared (IR) transmitter and receiver to perform IR modulation and transmission and reception. A central processing unit (20) for controlling the operation, an IR and RF integrated remote control module (100) including a storage device for storing predetermined programs and various control and command data, and a wired / wireless internet module using TCP / IP. Receiving remote control and monitoring commands for home automation from the wired or wireless computer terminal, Time-modulated command to generate the predetermined RF data, and transmit and receive the generated predetermined RF data to the IR and RF integrated remote controller module to perform a relay role between the wired / wireless computer terminal and the IR and RF integrated remote controller module. It comprises a box 200.

Referring to the operation of the home automation system using the IR and RF integrated remote control module, first, the user on the wired / wireless computer terminal 400, 500 side, the electronic device in the home automation system, for example, the lighting device in the home In order to give a command to turn off the remote control program is run to give the command of the iconized part.

The remote control command generated from the wired / wireless computer terminals 400 and 500 is applied to the set top box 200 through the internet access module, and the set top box 200 receives the remote control command applied through the internet module. RF modulation, the RF modulated remote control command is transmitted to the IR and RF integrated remote control module 100 by the RF transmission method, the IR and RF integrated remote control module 100 is a process as shown in FIG. After determining whether to use the IR transmission method or the RF transmission method, the modulated IR or RF command data is transmitted to be received by the receiving unit installed on the lighting device, so that the remote control desired by the operator, that is, the off operation of the lighting device is performed. .

The response signal according to the off operation of the lighting apparatus may be applied to the wired / wireless computer terminals 400 and 500 in the reverse order to the above process, and the image pickup apparatus connected to the camera interface unit 40 mentioned above ( 800 may be applied to the wired / wireless computer terminals 400 and 500 in the form of an image data to monitor the response of the command as an image.

If you want to remotely control the TV 600 or the refrigerator 700 using the conventional IR transmission method, the IR and RF integrated remote control module 100 uses the IR transmission method through the process as shown in FIG. In this case, the modulated IR command data is transmitted to be received by the receiving unit (not shown) installed on the television 600 or the refrigerator 700 so that the remote control operation desired by the operator is achieved.

However, the home automation system using the conventional IR and RF integrated remote control module is impossible to grasp the operation state after operating the device, and in order to grasp the state, it is possible to grasp the situation in the field using the imaging device. It is possible to check only the image, so it is not only possible to grasp the superficial state of the site, and only the temporal state change of each electronic product can be monitored, which makes it difficult to grasp various information about the electronic product. .
