Remote control device, electronic device and control methods thereof

A remote control device comprising:

• a user interface;
• a memory storing at least one instruction and a plurality of binary codes;
• a communication interface;
• and
• at least one processor operatively connected with the user interface, the memory, and the communication interface and configured to execute the at least one instruction to:
• identify, based on a user command receiving through the user interface, a binary code corresponding to the user command from among the plurality of binary codes,
• identify the binary code and regroup the binary code, based on a pre-set number of bit units, into a plurality of bit groups corresponding to the binary code, wherein the pre-set number of bit units is lower than a number of bits in the binary code, and
• control the communication interface to transmit a first pulse signal corresponding to the plurality of bit groups,
• wherein the at least one processor is configured to execute the at least one instruction further to control the communication interface to determine an interval between a pulse of a first group and a pulse of a second group directly after the first group based on a use distribution of binary data of the plurality of bit groups.
