In order to facilitate the further description of the remote controller of the present invention, the following is an example based on different application scenarios of the projection device and the terminal device.

(1) The first type of application scenario: a projection device, several remote controls, and one terminal device

As shown in FIG. 3, the projection device is wirelessly connected to the remote controller (such as a wifi connection), and the remote controller is connected to the terminal device USB, wherein the remote controller is provided with a button.

When the user needs to transmit the projection data on the terminal device to the projection device for projection, the user only needs to manually press the button set on the remote controller, so that the button response signal is generated by the button response circuit 60 and sent to the terminal device; When the device detects the button response signal, the terminal device will start to run the built-in driver of the remote controller, so that the data on the current terminal device graphics card and the sound card is acquired and transmitted to the remote controller through the USB connection in real time; after the remote controller receives the real-time, the first step is performed.

In this application scenario, the user simply inserts the remote controller into the terminal device through the USB interface to establish a USB connection with the terminal device. At the same time, the user turns on the NFC pairing function through the button on the remote controller, and then the projector device is controlled by the projection device. The NFC pairing of the two is completed to establish a wireless connection, thereby indirectly implementing a data connection between the projection device and the terminal device.

In addition, in this application scenario, for example, the user can trigger the terminal device to start real-time transmission of the picture and sound data to be projected through the button set on the remote controller, and the user can also trigger the terminal device to stop transmitting the picture through the button set on the remote controller. Sound data.

(2) The second type of application scenario: a projection device, several remote controls, multiple terminal devices

Scenario 1: A projection device, a remote control, and multiple terminal devices

As shown in FIG. 7, the projection device is wirelessly connected to the remote controller, and the remote controller establishes a USB connection with the terminal device A. The terminal devices B and C do not make any connection but only establish a USB connection with the remote controller when necessary. Among them, a button is provided on the remote controller.

This application scenario is basically the same as the first application scenario described above, so it is not described too much. In this application scenario, there are multiple terminal devices, so there may be a need to switch terminal devices.

In this application scenario, when the user needs to project the content on the terminal device B (or C), the user only needs to pull the remote controller from the terminal device A and insert it into the terminal device B (or C), so that the remote controller and the remote controller The terminal device B (or C) establishes a USB connection, and the manner in which the projection device projects the content on the terminal device B (or C) is substantially the same as the first application scenario described above, and thus will not be described in detail.

Scenario 2: One projection device, multiple remote controls, multiple terminal devices

As shown in FIG. 8, the projection device establishes a wireless connection with the remote controllers A, B, and C respectively, and the remote controller A establishes a USB connection with the terminal device A, and the remote controller B establishes a USB connection with the terminal device B, and the remote controller C and the remote controller The terminal device C establishes a USB connection, wherein the remote controller is provided with a button.

Optionally, when the projection device currently projects projection data forwarded by other remote controllers, the projection device switches the projection data forwarded by the other remote controllers currently projected to the projection data forwarded by the current remote controller. For example, the projection device is currently projecting the projection data A on the terminal device A forwarded by the remote controller A, and if the projection device receives (or detects) the projection data B on the terminal device B forwarded by the projection remote controller B, The projection data B on the terminal device B forwarded by the projection remote controller B is automatically switched.

In addition, it should be further explained that since the projection device and the remote controller are wirelessly connected, and the remote controller and the terminal device are connected by USB, the terminal device may not be in the same position space as the projection device, thereby facilitating the user to perform projection data source. Switch, as shown in Figure 9. In addition, the connection manners and the projection implementation manners of the plurality of projection devices and the plurality of remote control devices and the plurality of terminal devices are substantially the same as the above-mentioned application scenarios, and thus are not described in detail.
