摘要

An electronic apparatus and a control method thereof, and an external apparatus and a control method thereof. The electronic apparatus includes a communication unit which communicates with an external apparatus, and a controller which performs an operation corresponding to a key signal received through the communication unit, receives a setup signal through the communication unit to reset up an operation corresponding to a first key signal, and performs a second operation based on a result of the reset up when the first key signal is received through the communication unit. The setup signal sets up the first operation corresponding to the first key signal to be replaced by the second operation different from the first operation.
