Abstract

The embodiment of the invention provides a control system and a control method of an infrared remote control signal. The system and the method can improve the receiving probability of the infrared remote control signal of long-focus projection equipment on the premise of lower power consumption and cost, and can improve user experience. The control system comprises a remote controller, the long-focus projection equipment, a projection medium and an infrared signal enhancement device which is arranged away from the projection medium within a preset range, wherein the remote controller is used for transmitting the infrared remote control signal; the long-focus projection equipment and the infrared signal enhancement device are used for receiving the infrared remote control signal; the long-focus projection equipment is also used for executing corresponding operation and transmitting a feedback signal to the infrared signal enhancement device according to the infrared remote control signal after the infrared remote control signal is received; and the infrared signal enhancement device is also used for transmitting the infrared remote control signal to the long-focus projection equipment after the infrared remote control signal is received and the feedback signal is not received. The system and the method are applicable to the field of control of the infrared remote control signals.

Description

technical field [0001] The invention relates to the field of infrared remote control signal control, in particular to an infrared remote control signal control system and method. Background technique [0002] A telephoto projection device is a projection device that is more than three meters away from the screen for projection. This projection device is generally placed behind or above the user's viewing position. When users use it, they are accustomed to operating the infrared remote control against the projection medium (such as a projection screen or wall) of the projection device, so that the infrared remote control signal sent by the infrared remote control is reflected on the remote control receiving window of the projection device through the projection medium, and then the projection device The projection device is controlled according to the infrared remote control signal. [0003] However, due to the directionality of the infrared remote control signal, during the...
