The remote controller is a wireless transmitter, which encodes the key information through modern digital coding technology, emits light waves through infrared diodes, and the light waves convert the received infrared signals into electrical signals through the infrared receiver of the receiver, which are decoded in the processor and demodulated into corresponding instructions, so as to meet the operational requirements for controlling set-top boxes and other equipment.
