Referring to fig. 2, fig. 2 is a schematic flowchart of a screen projection control method for an intelligent device according to an embodiment of the present disclosure, which may be implemented based on the application environment described in fig. 1, and as shown in fig. 2, the method includes steps S201 to S203:
s201: and receiving a mirror image instruction sent by the intelligent equipment, wherein the mirror image instruction is used for establishing mirror image connection with the intelligent equipment.
In the embodiment of the present application, the smart device may specifically be a device supporting a screen mirroring function, such as a mobile phone, a tablet computer, and a computer with a wireless transceiving function. The intelligent equipment can establish mirror image connection by sending a mirror image instruction to the digital video conversion box under the same local area network WIFI; specifically, the intelligent device searches for all other devices which can establish mirror image connection and are under the same local area network WIFI, the other devices can include devices which can be connected with the WIFI and have a function of receiving mirror image pictures, such as a smart television and a digital video conversion box, the intelligent device selects the unique digital video conversion box through a unique identification number (a device name, a serial number, an input verification code and the like) and establishes mirror image screen projection connection through mirror image screen projection protocols such as a Miracast protocol, an Airplay protocol and a Google cast protocol.
Illustratively, the screen mirroring function can be realized through AirPlay by iPad (apple tablet) under the same WIFI as that of apple tv (digital video converter box introduced by apple), and the screen mirroring function of iPad is projected to a display connected with the apple tv through the apple tv for display. AirPlay is a wireless communication technology using WIFI from apple inc. Video images on the iPhone, iPod, iPad and Mac can be transferred to a device (such as a stereo or Apple TV) supporting AirPlay for playing. Therefore, before mirror image connection is established between the iPad and the AppleTV, the AirPlay function of the AppleTV needs to be opened, then the iPad and the AppleTV are connected with the same WIFI, screen mirror image starting is selected on the iPad, then the AppleTV is selected, at the moment, the AppleTV displays a password on a display, and screen mirror image can be started after the password is input on the iPad.
S202: and receiving the mirror image sent by the intelligent equipment, and sending the mirror image to a display for displaying.
In the embodiment of the application, after the intelligent device is connected with the digital video conversion box, the intelligent device continuously sends the mirror image to the digital video conversion box through the mirror image protocol, and after the digital video conversion box receives the mirror image sent by the intelligent device, the received image is rendered and modified according to actual requirements or control intelligence and then sent to the display to be displayed, or the mirror image sent by the intelligent device is directly sent to the display without being processed, so that the instantaneity of mirror image projection is ensured. The display can be any display supporting video input and display, such as a television, a smart television, a desktop display and the like.
In a possible embodiment, receiving a mirror image sent by a display smart device, and sending the display mirror image to a display for displaying includes: receiving a mirror image of the intelligent display device; adjusting the mirror image of the display to a first display frame rate; and sending the mirror image picture of the display to the display for displaying according to the first display frame rate of the display.
Specifically, according to different settings of the intelligent device and different display specifications, the frame rate of a mirror image output by the intelligent device and the frame rate supported by the display are different, and due to a persistence mechanism of human eyes, as long as the frame rate of a video is higher than 24fps, namely, more than 24 images are displayed per second, the video can form a continuous image in the sight of human, but the video image displayed at a higher frame rate is smoother and coherent in human eyes. Therefore, after receiving the mirror image sent by the intelligent device, the video digital conversion box adjusts the mirror image of the receiving band to the most appropriate first frame rate according to the output capability of the intelligent device and the highest display frame rate supported by the display, and then sends the mirror image to the display for display.
In one possible embodiment, adjusting the mirror image to the first display frame rate includes: acquiring the highest display frame rate supported by intelligent equipment and the highest display frame rate supported by a display; calculating to obtain a frame rate difference value between the highest display frame rate supported by the intelligent equipment and the highest display frame rate supported by the display; if the frame rate difference is smaller than or equal to a preset threshold value, determining the larger display frame rate of the highest display frame rate supported by the display and the highest display frame rate supported by the intelligent equipment as a first display frame rate; and if the frame rate difference value is larger than a preset threshold value, determining a smaller display frame rate in the highest display frame rate supported by the display and the highest display frame rate supported by the intelligent equipment as a first display frame rate.
Specifically, according to the system of the display, the screen refresh rate specification supported by the display is generally 30Hz, 60Hz, 120Hz, 144Hz, and the like, which respectively correspond to the input mirror image frame rates of 30fps, 60fps, 120fps, 144fps, and the like. If the frame rate of the input mirror image is higher than the refresh rate supported by the display, if the final display result at the moment when the input mirror image is 60fps but the highest refresh rate supported by the display is 30Hz is consistent with the mirror image input at 30fps, at this moment, 30fps corresponding to the refresh rate of the display can be used as the first display frame rate to limit the frame rate of the mirror image input by the intelligent device to be 30fps, and the file size of the mirror image input at 30fps to be smaller than the mirror image input at 60fps. Similarly, if the frame rate of the input mirror image is lower than the refresh rate supported by the display, for example, the frame rate of the input mirror image is 60fps but the highest refresh rate supported by the display is 120Hz, if the mirror image of 60fps is directly sent to the display of 120Hz corresponding to 120fps for display, problems such as screen flicker and intermittent black screen may occur, and at this time, the frame rate of 60fps supported by the intelligent device may be used as the first display frame rate, and the refresh rate of the display may be adjusted to 60Hz corresponding to 60fps.
Illustratively, depending on the performance of the smart device, the connection protocol selected by the smart device and the digital video converter box, and whether the network connection is in a steady state, the frame number of the mirror image output by the smart device may fluctuate, for example, from 60fps to 55fps, and the objective factor rejection may revert to 60fps after a short reduction. Or the mirror image output by the intelligent device is 59fps according to the device performance, but if the refresh rate of the display is 60HZ which can support the display of the mirror image of 60fps, the display frame rate of the intelligent device and the display device of the display can be obtained at this time, and the frame rate difference between the intelligent device and the display device is calculated, if the frame rate difference is lower than the preset threshold, the preset threshold can be an integer such as 1, 3, 5 frames, etc. If the frame rate of the input mirror image frame does not reach 60fps corresponding to 60Hz, the refresh rate of the display is unnecessarily adjusted to 30Hz corresponding to 30fps, and if the difference value between the frame rate of the input mirror image frame and the frame rate supported by the display is smaller than a preset value, the display can be continuously displayed at the refresh rate of 60Hz.
It can be seen that, in the embodiment of the present application, by analyzing the frame rate difference between the mirror image frame rate output by the intelligent device and the frame rate difference corresponding to the refresh rate supported by the display, the maximum frame number output under the condition of ensuring that the final display image is normally displayed is selected, so that the performance of the intelligent device and the display is exerted to the maximum extent, and the image quality of the mirror image displayed by the display in the mirror image projection mode is ensured.
S203: and receiving a screen clearing instruction of the intelligent equipment, and modifying the mirror image sent to the display according to the screen clearing instruction.
In the embodiment of the application, the digital video conversion box can modify the received mirror image sent by the intelligent device according to the screen clearing instruction sent by the intelligent device, clear unnecessary contents in the mirror image, and then send the cleared mirror image to the display for displaying.
In a possible embodiment, receiving a screen clearing instruction of an intelligent device, and modifying a mirror image sent to a display according to the screen clearing instruction includes: acquiring first display content corresponding to a display screen clearing instruction in a container, wherein the display container comprises a corresponding relation between a plurality of preset instructions and a plurality of display contents; determining a display picture corresponding to first display content of the display in the mirror image picture of the display, and clearing the display picture of the display according to a display clearing instruction to obtain a modified mirror image picture; and sending the mirror image picture modified by the display to the display for displaying.
Specifically, please refer to table 1, where the preset instruction may be sent by the smart device and received by the digital video converter, so as to implement functions such as changing a display effect and a display mode of a mirror image displayed by the display. The method specifically comprises the following steps: a screen clearing instruction for realizing a screen clearing effect; playing instructions for realizing playing, pausing, previous and next playing effects and the like; disconnection is realized; control commands for changing functions such as picture quality.

| Type of instruction | Instruction function | Form of expression |
| Clear screen instruction | Effect of cleaning screen | Turn on the screen-clearing mode, etc |
| Play instructions | Play effect | Play, pause, etc |
| Control instruction | Function control | Disconnection, etc |
Exemplarily, the first display content may be a virtual control key in an image, where the virtual control key is a preset instruction corresponding to various display contents; the control instruction may specifically include a control instruction for playing, pausing, fast forwarding, fast rewinding, and the like, of the video file, or may also be a control instruction for controlling starting of showing, previous, next, and the like. Referring to fig. 3, fig. 3 is a schematic view of a screen clearing effect of a mirror image provided in an embodiment of the present application, where as shown in a in fig. 3, first display contents at upper and lower ends of the mirror image are virtual control keys that are disconnected from a function menu, where the function menu may further include virtual control keys corresponding to instructions for switching a screen clearing mode and adjusting quality of the mirror image, and the virtual control keys at the lower half represent virtual control keys for returning, playing, previous instruction, and next instruction, and the virtual function keys block part of contents of a picture to be displayed. Referring to b in fig. 3, after the image connection is established in the digital video conversion box, the intelligent device may directly ask the user whether the user needs to start the screen clearing mode in a pop-up window manner, or the user manually starts the screen clearing mode through a virtual control key of the function menu. After a user selects to start a screen clearing mode, the intelligent device sends a screen clearing instruction to the digital video conversion box, the digital video conversion box clears a mirror image sent by the intelligent device according to the screen clearing instruction, the cleared mirror image is obtained as shown in a picture b in a figure 3 and is sent to the display to be displayed, the display image of the display at the moment is shown in the picture b in the figure 3, the intelligent device still displays the image as shown in a in the figure 3, the user can continue to send the instruction to control the mirror image displayed on the display according to the virtual control keys at the upper end and the lower end, and when the user selects to close the mirror image, the display image of the display is changed into the mirror image without screen clearing, namely, the display and the intelligent device both display the images as shown in the picture a in the figure 3.
