Description

Pairing method of projection device and projection device using the method

The present invention relates to a method and an electronic device, and more particularly, to a method for pairing a projection device via an external remote control device and a projection device using the method.

At present, the projectors on the market usually use an infrared remote control to implement remote control, but most users only use the function of turning the machine on and off, and other functions such as language or projection methods are not frequently used. When a user needs a projector, the user needs to use a variety of different remote controls to pair devices including a projector, a screen or an image source device. The above process is quite cumbersome for the user.

In order to reduce the number of remote controllers that users need to use, some remote controllers on the market have a learning function. The remote control with learning function can copy the infrared code (IR code) of other remote control. The remote control that has copied the infrared code of other remote control can realize the purpose of one-to-many control. However, there is often a difference between the copied infrared code and the original infrared code, which often causes problems such as insensitive remote control or reduced control distance. In addition, compared with general remote controllers, remote controllers with learning functions are more expensive and have fewer models.

FIG. 2 is a flowchart illustrating a method for pairing the projection device 100 via an external remote control device according to an embodiment of the present invention.

In step S201, the human-machine interface 140 may generate a trigger signal in response to a first operation (eg, an operation from a user), for example, the first operation may be pressing a button of a learning function on the human-machine interface 140 to trigger the signal It can be used to enable the learning function of the projection device 100 . For example, the human-machine interface 140 can display an OSD menu, and the user can activate the learning function of the projection apparatus 100 by clicking a function key corresponding to the learning function in the OSD menu.

In step S202, the processor 110 may receive the first signal through the receiver 130 in response to the trigger signal. Specifically, after the trigger signal enables the learning function of the projection device 100 , the processor 110 can enable the receiving function of the receiver 130 according to the trigger signal, so as to receive the first signal through the receiver 130 . In this embodiment, the first signal is, for example, an infrared signal sent by the remote control device 160, but the present invention is not limited thereto. In addition, the first signal may include one or more commands corresponding to the remote control device 160 . For example, the first signal may be, for example, an instruction corresponding to a button of the remote control device 160 . For another example, the first signal may be, for example, a combination composed of a plurality of commands respectively corresponding to a plurality of keys of the remote control device 160 .

After inputting the first signal to the processor 110, in step S203, the processor 110 can decode the first signal to generate a decoding result, wherein the decoding result can include a key combination corresponding to the first signal, for example, the user presses the remote control device 160 is the power button, then the processor 110 can know that the button pressed by the user is the power button after decoding the infrared signal (the first signal) corresponding to the power button.

In step S204, the processor 110 may receive the third signal through the receiver 130 after generating the decoding result. In this embodiment, the third signal is, for example, an infrared signal sent by the remote control device 160, but the present invention is not limited thereto. In addition, the third signal may include one or more commands corresponding to the remote control device 160 . For example, the third signal may be, for example, an instruction corresponding to a key of the remote control device 160 . For another example, the third signal may be, for example, a combination composed of a plurality of commands respectively corresponding to a plurality of keys of the remote control device 160 .

In one embodiment, the processor 110 may prompt the user to operate the remote control device 160 through the man-machine interface 140 to send a third signal that is the same as the first signal.

In step S205, the processor 110 may decode the third signal to generate a second decoding result, wherein the second decoding result may include an infrared code generated after the third signal is decoded. In one embodiment, after generating the decoding result corresponding to the third signal, the processor 110 may prompt the user to operate the human-machine interface 140 through the human-machine interface 140 . The human-machine interface 140 may receive a second operation (eg, an operation from a user) to correspond the decoding result to at least one function of the projection apparatus 100 corresponding to the second operation.

In step S206, the processor 110 compares the decoding result (ie: the decoding result generated according to step S203) and the second decoding result (ie: the second decoding result generated according to step S205). If the decoding result matches the second decoding result, go to step S208. If the decoding result does not match the second decoding result, go to step S207.

In step S207, the processor 110 may determine that the decoding result is incorrect. In one embodiment, the processor 110 can prompt the user that the decoding result is wrong through the human-machine interface 140 . In other words, the execution of the learning function of the projection apparatus 100 fails. The user needs to perform the learning function of the projection apparatus 100 again.

In step S208, the processor 110 may correspond the decoding result to at least one function of the projection apparatus 100, wherein the at least one function may correspond to the second operation described in step S203 or step S205.

The decoding result is selected as at least one function of the projection apparatus 100 .

The above-mentioned at least one function may include, but is not limited to, power on, power off, volume adjustment, signal source selection, keystone correction, or image parameter adjustment functions. For example, the user can operate the human-machine interface 140 to correspond the decoding result to the power-on function of the projection device 100 . In the future, if the decoding result of the signal received by the processor 110 through the receiver 130 matches the decoding result corresponding to the power-on function, the processor 110 can perform the power-on function according to the received signal.

The above steps can prevent the user from setting the wrong function. After step S203, the user can prompt the user to set the function first. At step S205, the user sets the function again, and the processor 110 can verify whether the two set functions are the same. Make sure the user is set to the correct function.

Since the projection device 100 is in the process of learning the command of the remote control device 160, the signal sent by the remote control device 160 may be affected by noise and distorted. In order to ensure that the decoding result decoded by the projection device 100 matches the signal sent by the remote control device 160 , the projection device 100 of the present invention can ask the user to send the same two signals through the remote control device 160 . If the two signals are matched, the projection device 100 corresponds the decoding result associated with the two signals to at least one function of the projection device 100 . If the two signals do not match, it means that at least one of the two signals may be distorted by noise. Therefore, the projection apparatus 100 does not correspond the decoding results associated with the two signals to at least one function of the projection apparatus 100 .

FIG. 3 is a flowchart illustrating a method of controlling the projection device 100 through the remote control device 160 according to an embodiment of the present invention. After the projection device 100 corresponds the decoding result of the first signal from the remote control device 160 to at least one function of the projection device 100 , the user can trigger the projection device 100 by sending a second signal associated with the first signal through the remote control device 160 . perform the at least one function. Specifically, in step S301 , the processor 110 may receive the second signal from the remote control device 160 through the receiver 130 . In step S302, the processor 110 may perform at least one function corresponding to the first signal in response to the second signal matching the decoding result corresponding to the first signal.

To sum up, the projection device of the present invention can adapt to various remote controllers through the learning function. The user can turn on the learning mode of the projection device through the man-machine interface of the projection device. During the learning process, the projection device can receive a signal from an external remote control device, and correspond the signal to the function of the projection device. Then, if the projection device receives the same signal as the signal, the projection device can execute the corresponding function according to the signal. In this way, the effect of using the external remote control device to perform one-to-many control can be realized, thereby reducing the number of remote controls that need to be operated by the user. On the other hand, the existing projection apparatus can implement the method of the present invention through software/firmware update without adding additional hardware components.
