[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] This application provides a screen projection method, apparatus, and computer-readable storage medium.

[0047] Please see Figure 1a , Figure 1aThis is a schematic diagram of the screen projection system provided in this application embodiment. The system may include at least one computer device 1000, a screen projection device 2000 connected to the computer device 1000, a device 3000 to be projected onto, and a network 4000. The computer device 1000 and the screen projection device 2000 can be connected via USB or Type-C direct connection. After connection, the screen projection device 2000 connects to the device 3000 to be projected onto via the network 4000, thereby realizing the screen projection function of projecting the screen from the computer device 1000 onto the device 3000. The network 4000 can be a wireless network or a wired network, such as a wireless local area network (WLAN), local area network (LAN), cellular network, 2G network, 3G network, 4G network, 5G network, etc. Additionally, the computer devices 1000 can also connect to each other using their own Bluetooth network or hotspot network.

[0048] This application provides a screen mirroring method, which can be executed by a screen mirroring device 2000. For example... Figure 1a As shown, the screen projector 2000 acquires the primary connection channel of the device to be projected into the storage; determines whether a connection can be established with the device to be projected into the storage based on the primary connection channel within a first preset time period, and obtains a first determination result; based on the first determination result, a connection is established with the device to be projected into the storage. In this way, by prioritizing the scanning of the primary connection channel of the device to be projected into the storage during channel scanning, blind multi-channel scanning is avoided, thereby shortening the connection establishment time between the screen projector and the device to be projected into the storage, and improving the user experience.

[0049] It should be noted that, Figure 1a The schematic diagram of the screen projection system shown is merely an example. The screen projection system and scenarios described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of screen projection systems and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0050] In this embodiment, the description will be from the perspective of the projection device, which can be integrated into a computer device that has a storage unit and a microprocessor and thus computing power.

[0051] Please see Figure 1b , Figure 1b This is a flowchart illustrating the screen mirroring method provided in an embodiment of this application. The screen mirroring method includes:

[0052] In step 101, the primary connection channel of the stored device to be projected is obtained.

[0053] Before connecting the screen sharing device to the computer, it needs to connect to the device to be shared with. This is done by running a thread and sending commands to obtain basic information about the device. This basic information may include the device's Service Set Identifier (SSID), Password Key (PSK), and primary connection channel. After obtaining this basic information, the screen sharing device stores it in its storage space.

[0054] Specifically, after the screen mirroring device is connected to the computer device, it retrieves the primary connection channel stored in the storage space. For example, the primary connection channel is channel 3.

[0055] In step 102, it is determined whether a connection can be established with the device to be projected based on the primary connection channel within a first preset time period, and a first determination result is obtained.

[0056] In this application, the first step is to detect whether the projection device can establish a connection with the device to be projected on based on the primary connection channel within a first preset time period, and to obtain a first determination result.

[0057] In step 103, based on the first determination result, a connection is established with the device to be projected.

[0058] Specifically, when the first determination result indicates that a connection can be established with the device to be projected on the primary connection channel within a first preset time period, a connection is established with the device to be projected on the primary connection channel based on the SSID and PSK.

[0059] In some implementations, the step of establishing a connection with the device to be projected based on the first determination result includes:

[0060] (1) If the first determination result indicates that no connection has been established with the device to be projected based on the primary connection channel within the first preset time period, then the channel configuration table of the device to be projected is obtained.

[0061] (2) Based on the channel configuration table and the primary connection channel, determine multiple candidate connection channels;

[0062] (3) Determine whether a connection can be established with the device to be projected on based on any one of the multiple candidate connection channels within a second preset time period, and obtain a second determination result;

[0063] (4) Based on the second determination result, establish a connection with the device to be projected.

[0064] If the first determination result indicates that no connection has been established with the device to be projected via the primary connection channel within a first preset time period, it means that a connection with the device to be projected via the primary connection channel cannot be obtained. Therefore, the stored channel configuration table of the device to be projected is retrieved. The channel configuration table is a channel configuration table pre-set for the device to be projected at the factory, and this channel configuration table is obtained when the projector attempts to connect with the device to be projected.

[0065] Table 1

[0066]

[0067] Specifically, as shown in Table 1, Table 1 shows the mapped channels corresponding to multiple channels. The mapped channels are used to indicate the channel number of the communication mapped channel corresponding to multiple channels.

[0068] Specifically, multiple candidate connection channels are determined using a channel configuration table and a primary connection channel; a second determination result is obtained by determining whether a connection can be established with the device to be projected within a second preset time period based on any of the multiple candidate connection channels; and a connection with the device to be projected is established based on the second determination result.

[0069] Specifically, the second preset time period can be the same as or different from the first preset time period; this is not limited here. When the primary connection channel cannot establish a connection with the device to be projected, the system prioritizes determining whether any one of the multiple candidate connection channels can establish a connection with the device to be projected within the second preset time period. This avoids blind multi-channel scanning, thereby shortening the connection establishment time between the projector and the device to be projected, and improving the user experience. Based on the second determination result, a connection is established with the device to be projected.

[0070] In some implementations, the step of determining multiple candidate connection channels based on the channel configuration table and the primary connection channel includes:

[0071] (1.1) Determine the target mapping channel, which includes the primary connection channel, from the multiple candidate mapping channels in the channel configuration table;

[0072] (1.2) Determine the connection channels other than the primary connection channel among the multiple connection channels corresponding to the target mapping channel as candidate connection channels to obtain multiple candidate connection channels.

[0073] Specifically, the method for determining multiple candidate connection channels based on the channel configuration table and the primary connection channel is as follows: determine the target mapping channel, which includes the primary connection channel, from the multiple candidate mapping channels recorded in the channel configuration table; determine the connection channels other than the primary connection channel from the multiple connection channels corresponding to the target mapping channel as candidate connection channels, thereby obtaining multiple candidate connection channels.

[0074] For example, if the primary connection channel is channel 3, and the multiple candidate mapping channels in Table 1 are mapping channels 1, 5, 9, 36, 60, 116, 140, 36+40, and 116+120 respectively, then the mapping channel including channel 3 is mapping channel 1, which is the target mapping channel. The channel range corresponding to mapping channel 1 is channels 1 to 4. Therefore, the connection channels in channels 1 to 4 other than channel 3 are determined as candidate connection channels, namely connection channel 1, connection channel 2, and connection channel 4, thus obtaining multiple candidate connection channels.

[0075] In some implementations, the step of establishing a connection with the device to be projected based on the second determination result includes:

[0076] (1.1) If the second determination result indicates that no connection has been established with the device to be projected within the second preset time period based on any of the multiple candidate connection channels, then it is sequentially determined whether any of the multiple other connection channels can establish a connection with the device to be projected.

[0077] (1.2) When there are other connection channels among the multiple other connection channels that can establish a connection with the device to be projected, establish a connection with the device to be projected.

[0078] Specifically, if the second determination result indicates that a connection cannot be established with the device to be projected using any of the multiple candidate connection channels, then a full channel scan is performed to determine whether any of the multiple other connection channels can establish a connection with the device to be projected; if there are other connection channels among the multiple other connection channels that can establish a connection with the device to be projected, then a connection is established with the device to be projected.

[0079] In some implementations, the step of establishing a connection with the device to be projected includes:

[0080] (1) Determine whether the Internet Protocol address sent by the device to be projected can be received within a specified time period;

[0081] (2) If an Internet Protocol address is received from the device to be projected within a specified time period, a connection is established with the device to be projected based on the Internet Protocol address.

[0082] The specific method for establishing a connection with the device to be projected is as follows: mutual link authentication is performed, an association is established, and a four-way handshake is used for user authentication and key negotiation when establishing a secure connection. After successfully obtaining the native Dynamic Host Configuration Protocol (DHCP) and Dynamic Internet Protocol Address (IP) addresses, the two parties establish a connection.

[0083] Specifically, it determines whether an Internet Protocol (IP) address sent by the device to be projected can be received within a specified time period. If an IP address sent by the device to be projected is received within the specified time period, it indicates that the DHCP IP address allocation function is normal. Then, a connection with the device to be projected is established based on the IP address.

[0084] In some implementations, before the step of determining whether an Internet Protocol address sent by the device to be projected can be received within a specified time period, the method further includes:

[0085] (1) Obtain the stored Bluetooth address of the device to be projected;

[0086] (2) Establish a Bluetooth connection with the device to be projected based on the Bluetooth address;

[0087] The method further includes:

[0088] (3) If no Internet Protocol address is received from the device to be projected within the specified time period, an Internet Protocol address request is sent to the device to be projected via the Bluetooth connection, triggering the device to be projected to respond with an Internet Protocol address request via the Bluetooth connection when it receives the Internet Protocol address request.

[0089] (4) Based on the Internet Protocol address provided in the feedback, establish a connection with the device to be projected.

[0090] Specifically, due to situations where the screen mirroring device cannot obtain its assigned IP address due to DHCP anomalies in the device to be mirrored, existing technologies perform Address Resolution Protocol (ARP) operations, inevitably leading to long connection times. Therefore, to further shorten the connection time with the device to be mirrored, this proposal establishes a Bluetooth connection with the device to be mirrored using the Bluetooth address of the device stored in the screen mirroring device before determining whether an Internet Protocol (IP) address sent by the device to be mirrored can be received within a specified time period. This generates a protocol data interaction link, i.e., an ATT connection. If an IP address sent by the device to be mirrored is not received within the specified time period, an IP address request is sent to the device to be mirrored via the Bluetooth connection. This triggers the device to respond with an IP address request via the Bluetooth connection upon receiving the request. Based on the responded IP address, a connection is established with the device to be mirrored.

[0091] To further shorten the connection time with the device to be projected, this proposal replaces the time-consuming ARP operation with a Bluetooth connection when no IP address is received from the device within a specified time period. This triggers the device to respond to the Internet Protocol address (IPA) request via Bluetooth, and a connection is established based on the returned IPA. This further reduces the connection time with the device to be projected.

[0092] In some implementations, after the step of establishing a connection with the device to be projected based on the feedback Internet Protocol address, the method further includes:

[0093] (1.1) Receive the primary connection channel update request sent by the device to be projected via the Bluetooth connection, wherein the primary connection channel update request carries the updated primary connection channel;

[0094] (1.2) Update the primary connection channel of the device to be projected to the updated primary connection channel.

[0095] Specifically, after the screen mirroring device establishes a connection with the device to be mirrored, if the user changes the primary connection channel of the device to be mirrored, the device to be mirrored will generate a primary connection channel update request based on the updated primary connection channel and send the primary connection channel update request to the screen mirroring device via Bluetooth. When the screen mirroring device receives the primary connection channel update request, it updates the stored primary connection channel of the device to be mirrored from the original primary connection channel to the updated primary connection channel.

[0096] Specifically, if the user changes other information about the device to be projected, such as the password, the updated information will be synchronized to the projector via Bluetooth connection.

[0097] As described above, this embodiment of the application obtains the primary connection channel of the device to be projected into the storage; determines whether a connection can be established with the device to be projected into the storage based on the primary connection channel within a first preset time period, and obtains a first determination result; based on the first determination result, a connection is established with the device to be projected into the storage. Therefore, by prioritizing the scanning of the primary connection channel of the device to be projected into the storage during channel scanning, blind multi-channel scanning is avoided, thereby shortening the connection establishment time between the device to be projected into the storage and improving the user experience.

[0098] To facilitate better implementation of the screen projection method provided in this application, this application also provides an apparatus based on the above-described screen projection method.

[0102] Module 303 is used to establish a connection with the device to be projected based on the first determination result.

[0103] In some implementations, module 303 includes:

[0117] Creating modules, submodules, or units is also used for:

[0118] If no Internet Protocol address is received from the device to be projected within the specified time period, an Internet Protocol address request is sent to the device to be projected via the Bluetooth connection, triggering the device to be projected to respond with an Internet Protocol address request via the Bluetooth connection upon receiving the Internet Protocol address request.

[0119] Based on the feedback Internet Protocol address, a connection is established with the device to be projected.

[0120] In some implementations, after establishing a connection with the device to be projected based on the feedback Internet Protocol address, the method further includes:

[0121] The receiving module is used to receive the primary connection channel update request sent by the device to be projected via the Bluetooth connection, wherein the primary connection channel update request carries the updated primary connection channel;

[0122] The update module is used to update the primary connection channel of the device to be projected to the updated primary connection channel.

[0123] In some implementations, the first determining submodule includes:

[0125] The third determining unit determines the connection channels other than the primary connection channel among the multiple connection channels corresponding to the target mapping channel as candidate connection channels, thereby obtaining multiple candidate connection channels.

The device to be mirrored can be a monitor, projector, or other display device.
