That is, the preset correspondence relationship refers to a mapping relationship between the remote control code and the preset operation instruction, and when the preset correspondence includes more than two mapping relationships, different remote control codes correspond to different presets. The operation instruction, the instruction type of the preset operation instruction may include three types of the motion instruction, the touch instruction, and the voice instruction, and each of the preset operation instructions may include one or more operation instructions.

In addition, the preset correspondence may include only a mapping relationship between a preset operation instruction of the instruction type and the remote control instruction, or may include only a preset operation instruction of any two instruction types and the remote control code respectively. The mapping relationship, of course, can also include the mapping relationship between the preset operation instructions of the three instruction types and the remote control code.

The following three types of motion commands, touch commands, and voice commands are respectively illustrated and described, as follows.

For example, if the instruction type of the preset operation instruction is a motion instruction, and if the remotely controlled device is a smart TV, the mapping relationship between the remote control code and the preset operation instruction may be as shown in Table 1 below.
