After receiving the first message, the screen-throwing device obtains the network address of the second system from the local according to the identifier of the second system carried in the first message, so as to send a second screen-throwing request to the display device, wherein the second screen-throwing request carries the identifier of the second system.

After receiving a second screen throwing request through the first system, the display equipment firstly sends the second screen throwing request to the second system according to the routing configuration recorded in the first system, wherein the routing configuration is used for realizing communication between the first system and the second system through a network card; and then sequentially sending a second message to the screen throwing device through the second system and the first system, wherein the second message is used for indicating to send the screen throwing data to the second system.

The second system may send the second message to the first system, and then the first system sends the second message to the screen-casting device.

And after receiving the second message, the screen throwing device sends the screen throwing data on the first device to the second system according to the network address of the second system, and the first device is connected with the screen throwing device. For example, the screen-casting device is plugged into the first device through a USB (universal serial bus ) interface.

Correspondingly, the display equipment receives screen throwing data through the first system; and sending the screen throwing data to the second system by the first system according to the route configuration recorded in the first system.

The routing configuration includes network routing information between the first system and the other systems, that is, which network card the first system sends the screen-throwing data to the other systems. The route configuration is obtained by pre-configuring the system and the network card of the display device.

Of course, after the display device receives the first screen-throwing request, if the user does not select the second system or selects the first system, the first system replies a third message, where the third message is used to indicate to send screen-throwing data to the first system, and the third message may carry the identifier of the first system.

And the screen throwing device sends screen throwing data to the first system according to the network address of the first system after receiving the third message.

And the display equipment receives the screen throwing data through the first system and displays an interface corresponding to the screen throwing data in the first system.

It should be noted that, before the screen-throwing device sends the first screen-throwing request to the display device, a communication link between the screen-throwing device and the display device needs to be established according to one of the at least two network information. The communication link is realized through a network card corresponding to the first network information, and is used for communication between the display equipment and the screen throwing equipment, and comprises a step of sending a first screen throwing request, a second screen throwing request, screen throwing data and a step of sending a first message and a second message to the screen throwing equipment by the screen throwing equipment.

The network information corresponding to the at least two network cards of the display device and the network address of each system of the display device are collectively called as information of the display device, and are written into the screen throwing device together when the screen throwing device is connected with the display device. Thus, after the user selects the second system, the screen projection system includes the network address of each system, that is, the network address of the second system. Therefore, the user is not required to reinsert the screen throwing device on the display device, so that the network address of the second system and the network information of the network card are written into the screen throwing system, and the operation complexity of the user is reduced.

Optionally, before sending the first screen-throwing request to the display device, the screen-throwing device may further acquire a default network address from the network addresses of the systems of the locally stored display device; and generating a first screen throwing request according to the default network address.

Wherein the default network address may be a specially marked network address.

Of course, the default network address may be flexibly set by the user. Specifically, the screen throwing device receives a default system switching instruction; and responding to a default system switching instruction, and switching the default network address in the network addresses of the systems by the screen throwing equipment.

In practical application, a flag may be set for a network address of one of the systems stored in the screen-throwing device, so as to indicate that the network address of the system is a default network address, and the system is the first system. The user may modify the tag for the purpose of switching the default network address.

The first system may be a default system, and a plurality of network cards exist in the first system to enable communication between the first system and the rest of the systems, and communication between the first system and the screen-throwing device. The display device in the embodiment of the application only sets the network card in the first device, so that each network card is single.

Fig. 4 schematically illustrates a system structure of a display device according to an embodiment of the present application. Referring to fig. 4, the display device includes two systems, an android system and a Windows system. Wherein, the android system is a first system. Of course, in practical application, the Windows system may also be used as the first system. In the embodiment of the application, one system can be selected from a plurality of systems in advance as the first system, and a plurality of network cards can be realized in the system so as to process a plurality of network signals.

Referring to fig. 4, three network cards are implemented in the android system: an AP (access point) network card, a WLAN (wireless local area network ) network card, an ETH (Ethernet) network card, wherein the ETH includes ETH0 and ETH1. Of course, the number of ethernet cards may be set according to the actual application scenario, which is not limited by the embodiment of the present application. Therefore, the screen throwing device can communicate with the android system through any network card, and the android system communicates with the Windows system through another network card. For example, the screen-throwing device may access a hot spot of the display device, so that the screen-throwing device may communicate with the android system through the AP network card, and the android system may communicate with the Windows system through the ETH1. Since the display device in fig. 4 is provided with an AP only in the android system, the display device in fig. 4 may be referred to as a single-hot-spot device.

As can be seen from fig. 4, the data between the android system and the Windows system needs to be converted by the two controllers C1 and C2. When the android system sends data to the Windows system, the controller C1 is required to convert the data from the USB signal to the network signal, then the control signal is required to convert the network signal to the USB signal again, and finally the USB signal is sent to the Windows system.

It can be seen that the display device and the screen projection device may form a multi-system screen projection processing system.

Fig. 5 illustrates an interaction schematic diagram between a screen projection device and a display device according to an embodiment of the present application. Referring to fig. 5, it can be seen that the interaction process between the screen-casting device and the display device may include the steps of:

s1, a screen throwing device sends a first screen throwing request to a display device, and the first screen throwing request is used for requesting screen throwing to a first system.

S2, after receiving the first screen throwing request, if a user selects a second system, the display device sends a first message to the screen throwing device, and the first message is used for indicating screen throwing to the second system.
