In this embodiment, the method for expanding the function of the display device includes the following steps:
step S10: and when the connection with the screen projection equipment is detected, establishing a connection path between the display end and the screen projection equipment.
It should be noted that the execution main body of this embodiment is a screen projection transmitter, where the screen projection transmitter may be an intelligent communication device externally connected to the screen projection device, and may also be other devices having the same or similar functions as the intelligent communication device, where the connection mode between the screen projection transmitter and the screen projection device may be socket connection (directly plugged in a Micro USB interface, a Type-C interface, a Lightning interface, or the like), and data line connection, which is not limited in this embodiment.
It should be noted that, as shown in fig. 2, a screen projector is provided, which includes: the screen projection device comprises a screen projection transmitter and a screen projection receiver, wherein the screen projection transmitter is used for being connected with first electronic equipment, the first electronic equipment is screen projection equipment, the screen projection receiver is used for being connected with second electronic equipment, the two electronic equipment is display equipment, a display equipment function expanding program is arranged in the screen projection transmitter, and an execution main body of the embodiment is the screen projection transmitter in the picture 2.
It can be understood that, when the device applied to the display end has a function expansion requirement, the function required by the display end cannot be realized on the display end or the use condition is not ideal, the function can be realized through the screen projection device in a cooperative work manner. For example: when the display end is the intelligent television, when the intelligent television needs to use the requirement function of face recognition, the intelligent television can not well recognize the face far away from the screen, and at the moment, the user image information can be collected by the camera on the screen projection equipment to perform face recognition on the intelligent television so as to complete the process of function expansion. By the method, the display end can complete corresponding functions by means of the hardware condition on the screen projection equipment under the condition that the display end does not have a corresponding hardware base.
It should be noted that the screen projection device is a device for providing an image data source, and a device for providing a video image in an instant screen projection scene, and the screen projection device may be a mobile phone, a computer, or other intelligent terminals, and this embodiment is not limited thereto.
It should be noted that the display end is a part for playing the screen-projected image in the screen-projected scene, and the display end includes a screen-projected receiver and a display device, the screen-projected receiver is used for communicating with the screen-projected transmitter, and the screen-projected transmitter automatically sends data to the receiving end when receiving the data transmitted by the screen-projected device, and then sends the data to the display device by the receiving end. The display device may be a television, an intelligent display, an intelligent projection device or other devices for playing video information, wherein the screen projection receiver is connected to the display device, and the connection between the screen projection receiver and the display device may be a socket connection (directly inserting the device into a USB interface, an HDMI interface, etc.), a data line connection or directly placing the screen projection receiver in the display device.
It will be appreciated that, to improve ease of use, for example: the plug-and-play function is realized, when the screen projection transmitter detects that the screen projection device is connected with the screen projection device, a communication line between the screen projection device, a transmitting end, a receiving end and the display device can be automatically established, a foundation is established for communication from the screen projection device to the display device, when the specific detection mode is in physical connection, when the plug is detected to be electrified, the wireless connection can be established, and then the wireless communication can be established.
In the embodiment, product information of the screen projection equipment is determined according to the screen projection request; determining a target data conversion protocol according to the product information; and establishing a connection path between the screen projection equipment and the display end according to the target data conversion protocol.
It should be noted that the data transmission mode of the screen projection device may be different from the communication mode of the screen projection transmitter and the display terminal, so that the screen projection transmitter may find a corresponding communication protocol according to the product information of the screen projection device, find a corresponding data conversion protocol according to the communication protocol to unify the communication modes of the screen projection device and the display terminal, and then establish a connection path between the screen projection device and the display terminal. For example: the protocol of the display and the screen projection receiver in the display end with the built-in screen projection receiver is uniform when the display and the screen projection receiver leave a factory, the display and the screen projection receiver are provided with the same privacy protocol as the screen projection transmitter, a mobile phone can be directly connected with the transmitting end, and the display and the screen projection receiver can be quickly connected through screen projection device equipment in a local area network; the display end externally connected with the screen projection receiver needs to access the receiving end on the display equipment, so that after the transmission protocol is unified, the mobile phone, the screen projection device, the television end, the screen projection receiver, the connection and the data transmission are carried out.
In the present embodiment, a user operation data packet is generated; sending the user operation data packet to a screen projection device through a connecting passage so that the screen projection device generates an operation program according to the user operation data packet, wherein the operation program is used for generating a device control instruction and feeding back the device control instruction; and when receiving the equipment control instruction, executing corresponding control operation according to the equipment control instruction.
It can be understood that, in this embodiment, the flow of the function expansion of the whole display device may also be controlled by the screen projection device, for example: after the connection path is established, the screen projector user can click on a mobile phone page to terminate transmission, or the screen projector is disconnected to finish the transmission of the real-time audio and video contents. Therefore, after the screen projection transmitter and the screen projection equipment are connected, a user operation data packet can be generated, and the user operation data packet is sent to the screen projection equipment through a connecting channel, so that the screen projection equipment generates an operation program according to the user operation data packet.
In a specific implementation, the user operation data package may be an installation package in which a control program is stored, so that the screen projection device may install the operation program, and the user operation data package may also be a link containing operation program downloading, and the screen projection device automatically downloads the operation program through the link to perform the operation.
Step S20: and acquiring the function request of the display end.
It should be noted that. The display end often can propose some function requests according to user's operation and the function of display end, can request to use the camera, also can request to upgrade wifi (when the TV can only connect the wifi of 2.4Ghz, upgrade to using the wifi of 5Ghz with the help of the wifi module of cell-phone) etc. for example: the content of the display end page popup prompt window comprises a request whether to use a camera, a microphone, Bluetooth and Wi-Fi of the mobile phone device, and when a display end user confirms that the request is received, the camera, the microphone, the Bluetooth and the Wi-Fi on the screen projection device can be directly used as expanded hardware for a television.
Step S30: and acquiring the control information of the target function module according to the connection path and the function request.
It can be understood that, according to the function request, it can know which function module the display end needs, so that the corresponding function module can be found to obtain the relevant control information used by the function module, and the relevant control information is collected, encoded and transmitted to the display end, where the control information is the relevant information for controlling the function module, for example: zooming and brightness adjustment of the camera, sound receiving adjustment and start-stop of the microphone, and the like.
Specifically, the target function module includes at least one item in wifi module, bluetooth module, microphone, image acquisition module and the audio playback module, also can acquire a plurality of function module's right of use simultaneously, through establishing a plurality of sub-passageways, lets different function modules and the mutual parallelism of display end, for example: and when the file is downloaded through 5Ghz, the display terminal is used as a display screen to control an image acquisition module of the screen projection equipment to take a picture.
In this embodiment, the corresponding function requirement information is determined according to the function request; judging whether the corresponding function authority is possessed or not according to the function requirement information; and when the screen projection equipment has the corresponding function right, the function request is sent to the screen projection equipment, so that the screen projection equipment feeds back corresponding control information according to the function request.
It should be noted that, corresponding function requirements need to be determined according to the function request, where the function requirements correspond to different function modules, for example, the function requirements are camera functions, so that it can be determined whether the image acquisition module has an authority to use, and the authority can be fed back to the display end to inform the user that the authority needs to be opened when the authority does not exist. And when the function right is possessed, the function request is sent to the screen projection equipment, and the screen projection equipment feeds back corresponding control information according to the request.
Step S40: and sending the control information to a display end according to the connection path so that the display end calls the target function module according to the control information.
In a specific implementation, after the connection path is established and the corresponding function module permission is obtained, the target function module may be called, for example: after connection is completed, when the television end needs related capabilities, the capability of the mobile phone can be acquired preferentially, data of the mobile phone is collected, coded and transmitted through the screen projector, information transmission is carried out on the mobile phone and the television through the screen projector, and the television end realizes the capabilities of using mobile phone Bluetooth search equipment, using higher-frequency Wi-Fi, collecting picture and sound of real-time video conversation, recording sound of K song, awakening voice and the like through decoding and playing.
In the embodiment, when the connection with the screen projection equipment is detected, a connection path between a display end and the screen projection equipment is established; acquiring a function request of the display terminal; acquiring control information of a target function module according to the connection path and the function request; and sending the control information to a display end according to the connection path so that the display end calls the target function module according to the control information. Through the mode, function expansion of the display equipment is achieved, and a connection channel between the display end and the screen projection equipment is established on the basis of the external equipment of the screen projection equipment, so that a communication basis is laid for calling the function modules of the screen projection equipment by the display end, the use right of each function module of the screen projection equipment is obtained through a built-in program in the external equipment, and the display end can complete corresponding functions by means of the hardware condition on the screen projection equipment under the condition that the display end does not have the corresponding hardware basis.
Referring to fig. 4, fig. 4 is a flowchart illustrating a function expanding method for a display device according to a second embodiment of the present invention.
Based on the first embodiment, before the step S30, the method for expanding functions of a display device in this embodiment further includes:
step S301: and acquiring information of the screen projection equipment.
It should be noted that the screen projection device information may be a device code, an identification code, or other information for identifying the identity of the screen projection device, and the type and model of the screen projection device may be determined according to the screen projection device information. The acquisition mode can be obtained by intercepting message data of the screen projection equipment information and analyzing the data of the header or the trailer of the message.
Step S302: and generating corresponding terminal control program parameters according to the screen projection equipment information.
It can be understood that the identity of the screen projection device can be confirmed according to the screen projection device information, and the corresponding terminal control program parameter is found from the data stored locally, and the terminal control program parameter is used for marking the manner of authority acquisition and applying for the authority of the corresponding functional module to the screen projection device.
In this embodiment, the screen projection device model information is queried according to the screen projection device information; determining the function type of the screen projection equipment according to the model information; and generating corresponding terminal control program parameters according to the function types.
It should be noted that, the model information of the screen projection device is queried according to the information of the screen projection device, and then the function type of the screen projection device is determined according to the model information, because different screen projection devices may have different function modules, for example: when the computer is used as a screen projection device, an image acquisition module may not be provided, and a part of mobile phones may not have a laser radar module, so that which function types the screen projection device has needs to be determined according to the type of the projection device, and then corresponding terminal control program parameters are generated according to the function types to apply for permission.
Step S303: and sending the terminal control program parameters to screen projection equipment so that the screen projection equipment acquires corresponding function permission according to the terminal control parameters.
It can be understood that the terminal control program parameters are sent to the screen projection device, so that the screen projection device obtains corresponding function permissions according to the terminal control parameters, and thus, before using the function, the screen projection device can automatically and intensively apply for all permissions of the screen projection device, and a user can authorize the screen projection device according to own requirements, so that the screen projection device does not need to apply for the permissions one by one during use, and the use experience of the user is optimized.
