Step S222: and reducing the display page by adopting a preset first page proportion to obtain the virtual display page.
After the mobile terminal receives the display page, the mobile terminal adopts a preset first page proportion to reduce the display page in order to adaptively display the display page, so as to obtain a virtual display page, wherein the virtual display page is the reduced display page. The first page proportion has multiple groups, and the received display pages can be reduced by selecting corresponding different first page proportions according to the display pages sent by the television terminals with different sizes.
According to the technical scheme, the display page is received, the display page is reduced by adopting the preset first page proportion, and the virtual display page is obtained, so that the self-adaptive display of the display page by the mobile terminal is realized.
As shown in fig. 4, in a third embodiment of the present application, a screen projection method of the present application, which is executed by a television terminal, includes the following steps:
step S310: and sending a display page in the current state to the mobile terminal according to a screen-casting connection request sent by the mobile terminal.
In this embodiment, after the mobile terminal and the television terminal are successfully bound, the mobile terminal sends a screen-casting connection request to the television terminal, and after receiving the screen-casting connection request, the television terminal sends a display page in its current state to the mobile terminal. After the television terminal sends the display page in the current state to the mobile terminal, the display page in the current state of the television terminal is always kept unchanged.
Step S320: and displaying the target screen projection information of the mobile terminal according to the screen projection instruction sent by the server.

As shown in fig. 5, in the fourth embodiment of the present application, step S320 includes the steps of:
step S321: and analyzing the screen projection instruction to obtain screen projection area information and the target screen projection information.
And after receiving a screen projection instruction sent by the server, the television analyzes the screen projection instruction to respectively obtain screen projection area information and target screen projection information, wherein the screen projection area information comprises side length parameters of a rectangular screen projection frame and position information of the rectangular screen projection frame in the virtual display page.
Step S322: and amplifying the side length parameter of the rectangular screen projection frame and the position information in the virtual display page respectively by adopting a preset second page proportion to obtain the position information of the target screen projection frame and the target screen projection frame.
Specifically, after the television end obtains the side length parameter of the rectangular screen projection frame and the position information of the rectangular screen projection frame in the virtual display page, in order to perform adaptive display on the rectangular screen projection frame, the preset second page proportion is adopted to amplify the side length parameter of the rectangular screen projection frame and the position information in the virtual display page respectively, and the position information of the target screen projection frame are obtained. The second page proportions have multiple groups, and the screen projection area information sent by the mobile terminals with different sizes can be amplified by selecting the second page proportions corresponding to different second page proportions.
Step S323: and reloading a display page according to the target screen projection frame and the position information of the target screen projection frame, and displaying the target screen projection frame on the reloaded display page.
And the television reloads the display page to generate a latest display page according to the target screen projection frame and the position information of the target screen projection frame, and the target screen projection frame is displayed on the latest display page after the latest display page is generated. And the position information of the target screen projection frame is used for determining the position of the target screen projection frame on the loaded display page.
Specifically, as shown in fig. 7, M 'represents a latest display page, N' represents a target screen projection box, and a to D represent application software loaded on the television. The process of reloading the display page by the television according to the target screen projection frame and the position information of the target screen projection frame to generate the latest display page can be understood as the process of fig. 6 to fig. 7.
Step S324: and displaying the target screen projection information in the target screen projection frame.
And after the television end displays the latest display page, displaying the target screen projection information sent by the user from the mobile end in a target screen projection frame on the latest display page, thereby completing screen projection. When the target screen projection information is displayed in the target screen projection frame, the user can use the remote controller to control other application software on the current latest display page of the television end, such as browsing videos, browsing pictures, playing games and the like. And controlling target screen projection information displayed in the target screen projection frame through the mobile terminal, such as controlling a picture displayed in the target screen projection frame to turn pages. It should be noted that the remote controller can only operate the application of the television, and the mobile terminal can only control the target screen projection information displayed in the target screen projection frame to perform a series of actions.
According to the technical scheme, the method comprises the steps of obtaining screen projection area information and target screen projection information by analyzing a screen projection instruction, respectively amplifying side length parameters of a rectangular screen projection frame and position information in a virtual display page by adopting a preset second page proportion to obtain the position information of the target screen projection frame and the position information of the target screen projection frame, reloading a display page according to the position information of the target screen projection frame and the position information of the target screen projection frame, displaying the target screen projection frame on the reloaded display page, and displaying the target screen projection information in the target screen projection frame.
