Remote controller, remote controlled electronic device, remote control system for electronic device and method thereof
A remote controller, a remote controlled electronic device, a remote control system for an electronic device and a remote control method for an electronic device are provided. The remote controller outputs a control code corresponding to a device ID, a device ID setting/change command and an operation command with respect to one or more electronic devices input from a user. The electronic device receives the device ID and/or control code from the remote controller and stores the received device ID. A control unit of the electronic device determines whether to operate in response to a control code received from the remote controller by checking whether the received device ID matches with the stored device ID. An output unit of the electronic device displays the device ID and/or a function in operation.
1. A remote controller, comprising:
an input unit for inputting a device ID, a device ID setting/change command, and an operation command from a user with respect to at least one electronic device;
a setting unit for setting an input device ID in the electronic device, in response to the device ID setting/change command;
an output unit for outputting a control code for controlling an operation of the electronic device; and
a control unit for outputting a control command to the output unit in response to receiving the device ID and/or the operation command with respect to the electronic device from the input unit, the control command directing the output unit to output the control code corresponding to the device ID and the operation command.
2. An electronic device comprising:
a receiving unit for receiving at least one of a device ID and a control code for setting or changing the device ID from a remote controller, the device ID identifies the electronic device from among a plurality of electronic devices;
a storing unit for storing the device ID; and
a control unit for determining whether the device ID received from the remote controller matches with the device ID stored in the storing unit, and determining whether to perform an operation instructed by the remote controller in response to the control code from the remote controller according to the determined result of whether the received device ID matches the stored device ID.
3. The electronic device of claim 2 , wherein the control unit outputs a control command to replace the device ID stored in the storing unit with the received device ID, when the control unit receives from the receiving unit the control code directing the change of the device ID received from the remote controller.
4. The electronic device of claim 2 , further comprising an output unit for displaying at least one of the device ID and a function in operation.
5. The electronic device of claim 4 , wherein the control unit outputs a control command to display or delete the device ID to the output unit irrespective of the determined result, when the control unit receives from the receiving unit the control code corresponding to display or deletion of the device ID received from the remote controller.
6. The electronic device of claim 2 , wherein the control unit performs the operation corresponding to the received control code irrespective of the determined result, when the control code from the remote controller corresponds to a power command.
7. A remote control system for an electronic device, comprising:
a remote controller for outputting a control signal for directing a setting or change of a device ID; and
at least one electronic device for, upon receipt of the device ID or a control code from the remote controller, determining whether to perform an operation instructed by the remote controller in response to the received control code from the remote controller by checking whether the received device ID matches with a pre-stored device ID.
8. The remote control system of claim 7 , wherein the remote controller comprises:
a setting unit for setting the device ID in at least one display unit;
an outputting unit for outputting a control code for controlling an operation of the display unit;
an input unit for inputting an operation command from a user; and
a first control unit for, upon receipt of at least one of the device ID from the setting unit and the operation command from the input unit with respect to the electronic device, outputting to the output unit a control command directing the output unit to output the control code corresponding to the received device ID and the operation command to the output unit.
9. The remote control system of claim 7 , wherein the electronic device comprises:
a receiving unit for receiving at least one of the device ID and control code from the remote controller;
a storing unit for storing the device ID; and
a second control unit for determining whether to perform an operation in response to a control code from the remote controller by determining whether the received device ID from the remote controller matches with the device ID stored in the storing unit.
10. The remote control system of claim 9 , wherein the control unit outputs a control command to replace the device ID stored in the storing unit with the received device ID when the control unit receives the control code from the remote controller directing a change of the device ID.
11. The remote control system of claim 10 , wherein the electronic device further comprises an output unit for displaying at least one of the device ID and a function in operation.
12. The remote control system of claim 11 , wherein the control unit outputs a control command to the output unit directing to display or delete the device ID irrespective of whether the received device ID matches with the stored device ID, when the control unit receives from the receiving a control code corresponding to the display or deletion of the device ID received from the remote controller.
13. The remote control system of claim 9 , wherein the control unit outputs a control command for performing the operation in response to a received control code from the remote controller irrespective of whether the received device ID matches with the stored device ID, when the control code from the remote controller corresponds to a power command.
14. A remote control method of an electronic device, comprising the steps of:
setting a device ID for at least one electronic device through a remote controller;
receiving at least one of the device ID and a control code from the remote controller; and
determining whether to perform an operation in response to a control code received from the remote controller by determining whether the received device ID matches with the set device ID.
15. The remote control method of claim 14 , wherein an operation in response to a control code received from the remote controller is performed irrespective of whether the received device ID matches with the set device ID, when the control code from the remote controller corresponds to a power command.
16. The remote control method of claim 14 , wherein the set device ID is changed to the received device ID when the control code from the remote controller directs the change of the device ID.
17. The remote control method of claim 14 , wherein the device ID is displayed or deleted irrespective of whether the received device ID matches with the set device ID, when the control code from the remote controller corresponds to a display or deletion of the device ID.
