1. An infrared transmission device, comprising:
a communicator receiving request data generated by an input device with a plurality of buttons; a buffer storing the request data;
a control circuit configured to determine that a repeat event occurs, based on an amount of the request data stored in the buffer;
a signal generator generating an infrared signal corresponding to the repeat event when the repeat event occurs; and
an infrared transmitter transmitting the infrared signal to an external electronic device, wherein:
the repeat event is an event in which a user continues to press a certain button, the plurality of buttons comprises two or more repeat buttons each configured to allow of a corresponding repeat operation,
the buffer comprises a plurality of buffer cells,
the control circuit determines that a repeat event of or to a first repeat button, out of the two or more repeat buttons, occurs only when request data corresponding to a press event of the first repeat button are stored in all the plurality of buffer cells, and
the signal generator generates an infrared signal corresponding to the determined repeat event of or to the first repeat button.
