A method of assigning an IR code set of a TV using a remote control, the method comprising:

• entering, by the remote control, a code set auto-scan mode when a set button is manipulated, and transmitting a scan mode entry request signal for requesting entry into the code set auto-scan mode to a set-top box;
• entering, by the set-top box, the code set auto-scan mode in response to the scan mode entry request signal, and transmitting a scan mode entry completion signal corresponding to the scan mode entry request signal to the remote control;
• outputting, by the set-top box, the number of a plurality of the IR code sets of an IR database (IRDB) received from the remote control on the TV;
• transmitting, by the set-top box to the remote control, an IR code set transmission request signal for requesting transmission of an IR signal of any one particular IR code set among the IR code sets, which are at least two in number, constituting the IRDB;
• and
• transmitting, by the remote control, the IR signal of the particular IR code set.
