The set-top box remote controller is used to control the set-top box and then control the TV. Take the remote control of Panda set-top box as an example, its remote control button consists of two parts, the former is used to replace the TV remote control, and the latter is used to control the set-top box. That is to say, even if there is no previous button, the latter button can control the set-top box and then control the TV.
The setting method of the Panda set-top box remote control is as follows: There is a setting button on the front of the set-top box remote control. When you press this button, a red light flashes in front of the remote control. At this time, the head of the set-top box remote controller is opposite to the head of the TV remote controller (the infrared emitting part in front of the remote controller is together), then press a button of the TV remote controller, and then press the corresponding button of the set-top box remote controller. In this way, relevant information will be input into the set-top box remote controller (for example, press the button on the TV remote controller, then press the button on the front of the set-top box remote controller, and then input the relevant information into the voice control button on the front of the set-top box remote controller), so that you can use the corresponding button on the set-top box remote controller to complete the corresponding control of the TV in the future. For example, controlling the volume of sound and so on.
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.
