Therefore, it is not so convenient for people to use them. By contrast, the design of smart TV remote control based on MCU possesses superiority, for instance, flexible programming, and casual setting of manipulation function and so on. Focusing on AT89C51 automotive microcontrollers, the design makes full use of MCU counter, timer, storage and interrupts system. In the meanwhile, it absorbs the advantages of infrared light, which mainly reflects in its controlling of the radiation frequency from infrared light for distinguishing various remote operating systems. The chief operational principle is that the remote control tells the kinds of operational systems by distinguishing radiation frequency emitted from infrared light. All this is to complete the progress of infrared emission and receiving. In general, it is of great use value and high cost performance. Also, it has complete software function and easy-made hardware circuit. Keywords: Microprocessor；Infrared rem
