The principles and manufacturing process are as follows:The infrared receiver REM can be the general integral infrared receiver, the outline is shown in figure 1, the infrared remote signal received by REM is then magnified by V1 and V2 and pushes the infrared emitting pipe to work. In the figure, the part out of the hidden line is installed in the lounge room, after the infrared emitting diode is connected with the receiving part by the coaxial-cable, it is set in a hidden place in front of the satellite TV set in the living room. With this equipment, it is convenient for people to watch TV with the remote control in their hands.
