[0006] In the conventional technology seen today, the data format of the infrared signal is defined by various infrared remote control protocols, and the various infrared remote control protocols are not compatible with each other, because the remote control devices of various manufacturers The infrared remote control protocols used are different. Therefore, electronic products, such as digital TV upper boxes, need to be equipped with their exclusive infrared signal decoding system to decode the received infrared signals and complete the process. For the operation that the user wants to perform, the remote control devices introduced by various manufacturers are not suitable for the operation of electronic products of other manufacturers, and it is not convenient to use
[0007] In addition, when the infrared remote control protocol used by the remote control device changes, the exclusive infrared signal decoding system originally equipped with the electronic product also needs to be replaced accordingly. As a result, the conventional infrared signal decoding system cannot flexibly support various An infrared remote control protocol, which greatly increases the manufacturing cost of electronic products
