On the other hand, the embodiment of the invention also provides a multi-screen image projection system. The multi-screen image projection system comprises: the terminal is connected with the local splicing screen.
Referring to fig. 5, a timing diagram of an operation process of the multi-screen image projection system according to the embodiment of the invention is shown.
The working process of the multi-screen image projection system comprises the following steps:
and 501, the terminal sends attribute information of the spliced screen to the server.
In this step, the terminal generates splicing screen attribute information from the number and arrangement of the display units in the splicing screen and the relevant data of the splicing screen, such as the size of the display area of each display unit, according to the attribute of the local splicing screen, and then sends the splicing screen attribute information to the server. Wherein, the properties of the spliced screen are as follows: the display screen comprises a total of 9 display units (namely, sub-screens forming the spliced screen) which are arranged in a 3 x 3 array, and the size of a display area of each display unit is as follows: 48mm 36 mm. In this step, the terminal informs the server of the attribute of the spliced screen to be subjected to image display by sending the attribute information of the spliced screen, so that the server performs subsequent processing on the attribute of the spliced screen.
And 502, the server generates a screen projection layout setting page according to the attribute information of the spliced screen, and synchronously displays the screen projection layout setting page and the terminal.
In this step, the server generates a screen-projection layout setting page in the operating system according to the received attribute information of the spliced screen, wherein the screen-projection layout setting page is used for the spliced screen local to the corresponding analog display terminal, and the screen-projection layout setting page can be synchronously displayed on the terminal and the server. Specifically, the screen projection layout setting page includes: and at least one operable object corresponding to the number and arrangement of the display units.
For example, referring to fig. 6, a page example diagram is set for the screen projection layout in the embodiment of the present invention. Corresponding to the spliced screen in the foregoing example, the screen projection layout includes 9 operable objects arranged in 3 × 3 array, and each operable object corresponds to a display unit in one spliced screen. Through the screen projection layout, the states of the spliced screens can be visually observed on both sides of the server and the terminal.
Step 503, the server selects display data according to the attribute information of the spliced screen, and acquires a URL address of the display data; and establishing an association relation between the display unit and the URL address of the display data.
In the step, the server correspondingly selects display data from a database which is preset on a network or the server and used for storing the display data according to the attribute information of the spliced screen; then, the URL addresses of the display data are acquired, respectively. As above, the server selects 9 display data corresponding to 9 display units, and then obtains the URL address of the display data.
After the display data and the URL address thereof are obtained, further, according to the attribute information of the spliced screen, an association relation between the display unit in the spliced screen and the URL address of the obtained display data is established. In this embodiment, if the number of the display data is the same as the number of the display units, a one-to-one correspondence relationship between the display units and the URL addresses of the display data is established, that is, the display data to be displayed corresponding to each display unit is set for each display unit through the association relationship.
In this embodiment, the number of the acquired display data is the same as the number of the display units, and obviously, according to specific display requirements, the number of the acquired display data may also be smaller than the number of the display units, that is, only a part of the display units need to display the display data, and the rest of the display units do not display the display data.
Step 504, the server returns the URL address of the display data, the association relationship between the display unit and the URL address of the display data to the terminal.
Through the steps, the server completes the corresponding setting of the display unit in the spliced screen and the display data (URL address of the display data) to be displayed according to the attribute information of the spliced screen, and in the step, the URL address of the display data and the incidence relation are returned to the terminal.
Step 505, the terminal establishes a display window corresponding to each display unit according to the attribute information of the spliced screen; the size of the display window is adaptive to the size of the display area of the display unit.
After the terminal receives the URL address and the incidence relation of the display data returned by the server, the terminal firstly reads the related data of the number of the display units and the size of the display area according to the attribute information of the splicing screen, establishes display forms with the same number as the display units according to the data, and distributes the display forms to the display units one by one for display, namely each display unit displays one display form. The size of the display window is the same as the size of the display area of the display unit, namely, one display window is displayed in each display unit in a full screen mode.
As described above, in this step, 9 display forms are established, and each of the 9 display units in the mosaic screen displays one display form, and each display form is displayed in full screen in the display unit.
Step 506, according to the association relationship between the display unit and the URL address of the display data, enabling the display unit to access the URL address of the display data associated with the display unit, and displaying the display data through the corresponding display window.
In this step, the terminal allocates the URL addresses of the display data to each display unit in a one-to-one correspondence manner according to the association relationship returned by the server. And enabling each display unit to access the URL address of the display data associated with the display unit, and displaying the display data through a display window currently displayed by the display unit.
As in the above example, the URLs of the corresponding display data are displayed in the 9 display forms of the 9 display units, respectively, and the display data is displayed. In the embodiment of the present invention, the display data may be: multimedia data such as video and pictures, and also can be web pages.
In some embodiments, the attribute information of the mosaic screen is updated according to modification information sent by the terminal or generated by the server, for example, according to adjustment of a user, a plurality of display units in the mosaic screen are combined to be used as one display unit. And the server reselects display data and updates the incidence relation according to the updating of the attribute information of the spliced screen, and then sends the incidence relation and the URL address of the reselected display data to the terminal, and the terminal receives the contents in real time and adjusts the display contents of the display window on each display unit of the spliced screen.
In some embodiments, the server of the present invention may further cooperate with a plurality of terminals to perform multi-screen image projection according to actual usage requirements and processing capabilities of physical devices.
In some embodiments, when data communication is performed between the server and the terminal, the association relationship among the attribute information of the spliced screen, the URL address of the display data, and the URL address of the display unit and the display data is encrypted, so as to improve data security.
Therefore, simple and efficient multi-screen image projection is realized through the method, the terminal, the server and the system formed by the server, and the server selects and allocates the URL address of the display data to be displayed by the display unit of the spliced screen according to the attribute information of the spliced screen provided by the terminal; the terminal automatically establishes a display window with the size corresponding to the display area of the display unit for the display unit of the spliced screen according to the setting of the server, and then accesses the URL address of the display data according to the setting of the server to enable the display window on the display unit to display corresponding content. In the whole multi-screen image projection process, excessive adjustment operation is not required by a user; in the implementation process, related hardware equipment in the prior art is not used, so that the application cost is low; the key processing part of the whole scheme is realized by a computer software system, so that the maintenance is convenient.
