Remote controller system and method for controlling multiple electronic devices

A remote control setting system comprising:

• a common remote controller comprising a plurality of input keys including each function key and each numeric key for assigning an operation of a different electronic device to each function key and controlling electronic devices;
• and
• a set-top box providing an image to a display device and exchanging a signal with the common remote controller in a bidirectional wireless communication manner,
• wherein the common remote controller enters a remote control setting mode by inputting any one function key of the plurality of input keys,
• wherein in assigning an operation of a selected electronic device to a predetermined function key in the remote control setting mode, when the set-top box and the electronic device are connected to each other through a high definition multimedia interface (HDMI), a manufacturer, a model name, and a recommended code set are displayed on the display device based on information about the electronic device detected by the set-top box, and
• wherein when the displayed recommended code set is selected by the input key, information about the selected code set is transmitted to the common remote controller to assign a function key corresponding to the code set.

A remote control setting method for assigning operations of different electronic devices to each function key of a common remote controller and controlling electronic devices, comprising the steps of:

• entering a remote control setting mode;
• displaying a manufacturer name based on information about an electronic device detected by a set-top box when the set-top box and the electronic device are connected to each other through a high definition multimedia interface (HDMI) and a plurality of recommended code sets corresponding to each model name of the manufacturer on a display device;
• transmitting the input key to the electronic device by operating a power function, key whenever information about the plurality of recommended code sets is automatically and sequentially transmitted from the set-top box to the common remote controller to assign an input key corresponding to the code set, in assigning an operation of a selected electronic device to a predetermined function key;
• and
• detecting whether the electronic device is turned off through the high definition multimedia interface (HDMI) by the set-top box, and stopping an automatic transmission of the code set if the electronic device is turned off.

• wherein when the displayed recommended code set is selected by the input key, information about the selected code, set is transmitted to the common remote controller to assign a function key corresponding to the code set, and
• wherein whenever information about the plurality of recommended code sets is sequentially and automatically transmitted to the common remote controller from the set-top box and an input key corresponding to the code set is assigned, a power function key is automatically operated to transmit it to the electronic device, and
• wherein the set-top box detects whether the electronic device is turned off through the high definition multimedia interface (HDMI), and an automatic transmission of the code set is stopped if the electronic device is turned off.
