The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

Those skilled in the art will appreciate that the structure shown in FIG. 1 does not constitute a limitation on the function expansion device of the display device, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

As shown in FIG. 1 , the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a display device function expansion program.

In the display device function expansion device shown in Figure 1, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the display device function expansion device of the present invention can be set in the display device function expansion device, and the display device function expansion device calls the display device function expansion program stored in the memory 1005 through the processor 1001, and executes the display device function expansion method provided by the embodiment of the present invention.

An embodiment of the present invention provides a method for expanding the functions of a display device. Referring to FIG. 3 , FIG. 3 is a flow chart of a first embodiment of a method for expanding the functions of a display device according to the present invention.

In this embodiment, the method for expanding the function of the display device includes the following steps:

Step S10: When a connection with the screen projection device is detected, a connection path between the display terminal and the screen projection device is established.

It should be noted that the executor of this implementation is a screen projection transmitter, which can be an intelligent communication device externally connected to the screen projection device, or other devices with the same or similar functions as the intelligent communication device. The connection method between the screen projection transmitter and the screen projection device can be a socket connection (directly plugged into a Micro USB port, Type-C port, Lightning port, etc.) or a data cable connection, which is not limited in this embodiment.

It should be noted that, as shown in Figure 2, a screen projector is shown, which includes: a screen projection transmitter and a screen projection receiver. The screen projection transmitter is used to connect to a first electronic device, wherein the first electronic device is a screen projection device, and the screen projection receiver is used to connect to a second electronic device, wherein the second electronic device is a display device. The screen projection transmitter is provided with a display device function expansion program, and the executive body of this embodiment is the screen projection transmitter in Figure 2.

It is understandable that when the device applied to the display end of this embodiment has a demand for function expansion, because the required function of the display end cannot be realized on the display end or the use conditions are not ideal, it can be realized through the coordinated work of the projection device. For example: when the display end is a smart TV, when the smart TV needs to use the face recognition function, because the user is far away from the screen and cannot perform face recognition well, at this time, the camera on the projection device can be used to collect user image information for facial recognition on the smart TV to complete the function expansion process. In this way, even if the display end does not have the corresponding hardware foundation, it can also complete the corresponding function by relying on the hardware conditions on the projection device.

It should be noted that the screen projection device is a device that provides an image data source, that is, a device that provides video images in the screen projection scenario. The screen projection device can be a mobile phone, a computer, or other smart terminals, which is not limited in this embodiment.

It should be noted that the display end is the part that plays the projection image in the projection scene. The display end includes a projection receiver and a display device. The projection receiver is used to communicate with the projection transmitter. When the projection transmitter receives the data transmitted by the projection device, it will automatically send the data to the receiving end, and then the receiving end sends it to the display device. The display device can be a TV, a smart display, a smart projector or other device for playing image information, wherein the projection receiver is connected to the display device, and the connection method between the two can be a socket connection (directly plugging the device into a USB interface, HDMI interface, etc.), a data cable connection, or directly building the projection receiver into the display device.

It is understandable that in order to improve the convenience of use, for example: to realize the plug-and-play function, when the projection transmitter detects that it is connected to the projection device, it can automatically establish a communication line between the projection device-transmitter-receiver-display device, thereby establishing a basis for communication from the projection device to the display device. The specific detection method is that when the physical connection is made, it is sufficient to detect when the plug is powered on, and the wireless connection is to establish wireless communication.

In this embodiment, the product information of the screen projection device is determined according to the screen projection request; the target data conversion protocol is determined according to the product information; and a connection path between the screen projection device and the display terminal is established according to the target data conversion protocol.

It should be noted that the data transmission method of the screen projection device may be different from the communication method between the screen projection transmitter and the display end. Therefore, the screen projection transmitter can find the corresponding communication protocol based on the product information of the screen projection device, and then find the corresponding data conversion protocol based on the communication protocol to unify the communication method between the screen projection device and the display end, and then establish a connection path between the screen projection device and the display end. For example: the protocol of the display and the screen projection receiver in the display end with a built-in screen projection receiver is unified at the factory, and it comes with the same privacy protocol as the screen projection transmitter. The mobile phone can be directly connected to the transmitter and quickly connected through the screen projection device in the local area network; the display end with an external screen projection receiver needs to connect the receiving end on the display device to unify the transmission protocol before the mobile phone, screen projection device, TV end, screen projection receiver, connection, and data transmission are carried out.

In this embodiment, a user operation data packet is generated; the user operation data packet is sent to the screen projection device through a connection path, so that the screen projection device generates an operation program according to the user operation data packet, and the operation program is used to generate device control instructions and feedback the device control instructions; when the device control instructions are received, the corresponding control operation is performed according to the device control instructions.

It is understandable that the present embodiment can also control the entire display device function expansion process through the screen projection device. For example, after establishing the connection path, the screen projection device user can click to terminate the transmission on the mobile phone page, or disconnect the screen projection device to end the real-time audio and video content transmission. Therefore, after the screen projection transmitter and the screen projection device are connected, a user operation data packet can be generated, and the user operation data packet can be sent to the screen projection device through the connection path, so that the screen projection device generates an operation program according to the user operation data packet. The specific process can be that the screen projection transmitter sends the installation package storing the control program as a user operation data packet to the screen projection device for installation to obtain the operation program. Through the control program, the screen projection device can complete the control of the display device function expansion process and even the display end in its own interface. The operation program is used to generate device control instructions. The user operates the operation program and then sends the operation instructions generated by the operation to the screen projection transmitter or the display end to complete the execution of the instructions.

In a specific implementation, the user operation data packet may be an installation package storing a control program for the projection device to install the operation program. The user operation data packet may also be a link for downloading the operation program, and the projection device automatically downloads the operation program through the link for operation.

Step S20: Obtaining the function request of the display terminal.

It should be noted that the display end often makes some function requests based on the user's operation and the function of the display end. You can request to use the camera or request to upgrade the wifi (when the TV can only connect to 2.4Ghz wifi, use the mobile phone's wifi module to upgrade to 5Ghz wifi), etc. For example: the pop-up prompt window on the display end page includes "whether to use the camera, microphone, Bluetooth, and Wi-Fi request of the mobile device". When the display end user confirms to accept the request, the camera, microphone, Bluetooth, and Wi-Fi on the projection device can be directly used as expansion hardware for the TV.

Step S30: Acquire control information of the target functional module according to the connection path and the functional request.

It can be understood that according to the function request, it is possible to know which function module the display end requires, so the corresponding function module can be found to obtain the relevant control information used by it, and collect, encode, and transmit it to the display end. The control information is the relevant information for controlling the function module, such as: camera zoom, brightness adjustment, etc., microphone reception adjustment, start and stop, etc.

Specifically, the target functional modules include at least one of a wifi module, a bluetooth module, a microphone, an image acquisition module, and an audio playback module. The right to use multiple functional modules can also be obtained at the same time. By establishing multiple sub-paths, the interactions between different functional modules and the display end can be parallel. For example: while downloading files through 5Ghz, the display end can be used as a display screen to control the image acquisition module of the projection device to take pictures.

In this embodiment, corresponding function requirement information is determined based on the function request; whether corresponding function permission is possessed is determined based on the function requirement information; when corresponding function permission is possessed, the function request is sent to the screen projection device, so that the screen projection device feeds back corresponding control information based on the function request.

It should be noted that the corresponding functional requirements need to be determined based on the functional request. The functional requirements correspond to different functional modules. For example, if the functional requirement is a camera function, it can be determined whether the user has the permission to use the image acquisition module. If the user does not have the permission, the user can be informed to the display end that the permission needs to be opened. If the user has the corresponding functional permission, the functional request is sent to the projection device, and the projection device can then feedback the corresponding control information based on the request.

Step S40: sending the control information to the display end according to the connection path, so that the display end calls the target functional module according to the control information.

In the specific implementation, after the connection path is established and the corresponding functional module permissions are obtained, the target functional module can be called. For example, after the connection is completed, when the TV needs relevant capabilities, it will give priority to obtaining the capabilities of the mobile phone, and collect, encode and transmit the data of the mobile phone through the screen projector. The information is transmitted between the mobile phone and the TV through the screen projector, and the TV side decodes and plays to realize the use of mobile phone Bluetooth search devices, use higher frequency Wi-Fi, real-time video call picture and sound collection, karaoke sound recording, voice wake-up and other capabilities.

When the present embodiment detects that it is connected to the screen projection device, it establishes a connection path between the display terminal and the screen projection device; obtains a function request of the display terminal; obtains control information of the target function module according to the connection path and the function request; and sends the control information to the display terminal according to the connection path, so that the display terminal calls the target function module according to the control information. Through the above-mentioned method, the function expansion of the display device is realized. This application establishes a connection path between the display terminal and the screen projection device based on the external device of the screen projection device, thereby laying a communication foundation for the display terminal to call the function module of the screen projection device, and then obtains the right to use each function module of the screen projection device through the built-in program in the external device, so that the display terminal can complete the corresponding function by relying on the hardware conditions on the screen projection device without the corresponding hardware foundation.

Refer to FIG. 4 , which is a flow chart of a second embodiment of a method for expanding the functions of a display device according to the present invention.

Based on the first embodiment, the method for expanding the function of a display device in this embodiment further includes, before step S30:

Step S301: Obtain screen projection device information.

It should be noted that the projection device information may be a device code, identification code or other information used to identify the projection device, and the type and model of the projection device may be determined based on the projection device information. The acquisition method may be to intercept the message data of the projection device information and parse the header or footer of the message to obtain the information.

Step S302: Generate corresponding terminal control program parameters according to the screen projection device information.

It can be understood that the identity of the projection device can be confirmed based on the projection device information, and the corresponding terminal control program parameters can be found from the locally stored data. The terminal control program parameters are used to mark the method of obtaining permissions and apply for permissions for the corresponding functional module from the projection device.

In this embodiment, the model information of the screen projection device is queried based on the screen projection device information; the function type of the screen projection device is determined based on the model information; and the corresponding terminal control program parameters are generated based on the function type.

It should be noted that the model information of the projection device is queried according to the projection device information, and then the function type of the projection device is determined according to the model information. This is because different projection devices may have different functional modules. For example, when a computer is used as a projection device, it may not have an image acquisition module, and some mobile phones may not have a lidar module. Therefore, it is necessary to determine which function types the projection device has according to the projection device type, and then generate corresponding terminal control program parameters according to the function type to apply for permissions.

Step S303: Send the terminal control program parameters to the screen projection device, so that the screen projection device obtains corresponding function permissions according to the terminal control parameters.

It can be understood that the terminal control program parameters are sent to the projection device so that the projection device obtains the corresponding functional permissions according to the terminal control parameters. In this way, various permissions of the projection device can be automatically applied for before using the function. Users can authorize according to their own needs, so that there is no need to apply for them one by one when using it, which optimizes the user experience.

This embodiment obtains the projection device information; generates corresponding terminal control program parameters according to the projection device information; and sends the terminal control program parameters to the projection device, so that the projection device obtains the corresponding functional permissions according to the terminal control parameters. Through the above method, it is possible to automatically obtain the various functional permissions of the projection device, find out which functional modules the projection device has through the projection device information, and obtain the determined functional module permissions. When using them, there is no need to apply for them one by one, which optimizes the user experience.

In addition, an embodiment of the present invention further provides a storage medium, on which a display device function expansion program is stored. When the display device function expansion program is executed by a processor, the steps of the display device function expansion method described above are implemented.
