With the advent of set-top boxes, infrared learning technology began to be applied in a large number on set-top box remote controllers for duplicating the infrared key values of television remote controllers, so as to realize the function that one remote controller can operate two devices (television and set-top box).
Taking a set top box remote controller as an example, the infrared learning function on the set top box remote controller is generally used in the following manner: the signal transmitting end of the infrared remote controller of the television is aligned to the signal receiving end of the set top box remote controller, when the set top box remote controller enters an infrared learning mode, the television remote controller presses a target key to transmit an infrared key value, and then the set top box remote controller receives the infrared signal and copies the infrared signal to be used. However, the above remote controller infrared learning scheme has the following drawbacks: 1. because the infrared communication technology has lower anti-interference capability, external interference is easy to receive in the infrared learning process, and particularly under strong light (such as under a fluorescent lamp, a balcony or window edge where sunlight irradiates, and the like), the probability of infrared learning failure is greatly increased; 2. when the carrier signal is identified, the set timeout time threshold is a fixed experience value (t 1 is temporarily set here), so that the method can only learn the infrared signal with the carrier frequency being greater than 1/t1 Hz, and the infrared signal carrier frequency range for learning in the infrared learning process is smaller and has large limitation.
