Apparatus and method for controlling electric appliances using broadcast wave, and apparatus and method for controlling home network

A method for controlling an electric appliance using a broadcast wave, comprising:

• receiving a broadcast wave including a product control information packet;
• comparing identification information included in the received product control information packet with that previously given to the electric appliance;
• confirming control data included in the product control information packet, if the identification information in the product control information packet is identical with that of the electric appliance;
• and
• performing a corresponding operation by controlling a function driving unit corresponding to a control object according to a control code, if the control data is the control code for controlling a function of the electric appliance.

A method for controlling a home network using a broadcast wave, comprising:

• enabling a first electric appliance to receive the broadcast wave including a product control information packet;
• comparing identification information included in the received product control information packet with that of the first electric appliance;
• enabling the first electric appliance to transmit the product control information packet to a second electric appliance through the home network, if the identification information in the product control information packet is not identical with that of the first electric appliance;
• and
• enabling the second electric appliance to control a function driving unit corresponding to a control object according to a control code in the product control information packet.

An apparatus for controlling a home network, comprising:

• a broadcast receiving module equipped in a first electric appliance for receiving a broadcast wave including a product guidance information packet;
• a communication module for communicating with a plurality of second electric appliances connected to the home network;
• a storage unit for storing identification information of the first electric appliance and information on a display function of a user interface respectively equipped in the first electric appliance and the second electric appliances;
• a user interface unit equipped in the first electric appliance for displaying guidance information included in the product guidance information packet;
• and
• a control unit for controlling in such a manner that the guidance information can be transmitted through the communication module by searching for the second electric appliance equipped at an user interface capable of displaying the guidance information, if identification information in the product guidance information packet received by the broadcast receiving module is identical with that of the first electric appliance stored in the storage unit, and the user interface can not display the guidance information.
