Disclosed are an infrared encoding data calibration method and device and a control method. The calibration method is used for the control terminal and includes receiving infrared encoding data of a display; judging the completeness degree of the infrared encoding data, feeding the judgment result back to the display; transmitting the infrared encoding data received to the display if the judgment result indicates that the infrared encoding data are complete, so that the display can calibrate. Based on the calibrated infrared encoding data, the terminal can be controlled, and reliability in control of the terminal can be improved.
