Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a screen projection display method, a smart terminal, and a storage medium. Background Technology

[0002] With the continuous advancement and development of technology, existing electronic devices such as mobile phones and tablets can now display data on screen-casting devices such as televisions via screen mirroring. Given the numerous applications available on these devices, it has become particularly important for users to know how to quickly open the corresponding window of the application to be cast on the screen-casting device.

[0003] The existing technology solution is as follows: During the screen projection process, the device to be projected first recommends applications that the user has frequently used recently. These applications are displayed on the screen projection device, and then the user needs to click on the screen projection device to open the corresponding window of the application.

[0004] However, existing technologies require users to manually participate on the screen projection device, which involves a long operation path and therefore suffers from low screen projection efficiency. Summary of the Invention

[0018] Optionally, after step S10, the method further includes:

[0019] S70: Identify applications whose usage frequency and / or usage duration are less than the hiding threshold when the source device corresponding to the device identifier is in the current mode state as hidden applications;

[0020] S80: Hide the application icon of the hidden application on the desktop.

[0021] Optionally, the method further includes:

[0022] S90: In response to the hide cancellation operation, the application icon of the hidden application is displayed on the desktop.

[0030] As described above, the screen projection method of this application includes the following steps: S10: After establishing a screen projection connection with the source device, receive the device identifier and current mode sent by the source device; S20: Find the recommended application corresponding to the device identifier and the current mode in a preset database; S30: Open and display the recommended application.

[0031] This application automatically triggers the opening and display of recommended applications corresponding to the current mode by searching for them in a preset database, without requiring manual intervention, thus improving the efficiency of application projection.

[0050] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0051] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0052] In the embodiments of this application, both the target device and the source device can refer to a smart terminal. Smart terminals can be implemented in various forms. For example, the smart terminals described in this application can include smart terminals such as mobile phones, tablets, laptops, handheld computers, personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers.

[0053] The following description will use a mobile terminal as an example. Those skilled in the art will understand that, apart from elements specifically designed for mobile purposes, the construction according to the embodiments of this application can also be applied to fixed-type terminals.

[0054] Please see Figure 1 This is a schematic diagram of the hardware structure of a mobile terminal implementing various embodiments of this application. The mobile terminal 100 may include: an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111, etc. Those skilled in the art will understand that... Figure 1 The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0055] The following is combined Figure 1 A detailed introduction to each component of the mobile terminal:

[0056] The radio frequency unit 101 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 110; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, and a duplexer. Furthermore, the radio frequency unit 101 can also communicate wirelessly with networks and other devices. The aforementioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), and 5G, etc.

[0057] WiFi is a short-range wireless transmission technology. Mobile terminals using the WiFi module 102 can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of the invention.

[0058] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, etc. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

[0059] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0060] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

[0061] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0062] User input unit 107 can be used to receive input numerical or character information, and generate key signal inputs related to user settings and function control of the mobile terminal. Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands sent by processor 110. In addition, touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may also include other input devices 1072. Optionally, other input devices 1072 may include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc., without being specifically limited here.

[0063] Optionally, the touch panel 1071 may cover the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. Subsequently, the processor 110 provides corresponding visual output on the display panel 1061 based on the type of touch event. Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

[0064] Interface unit 108 serves as an interface through which at least one external device can connect to mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, and so on. Interface unit 108 may be used to receive input (e.g., data, power, etc.) from the external device and transmit the received input to one or more elements within mobile terminal 100, or it may be used to transmit data between mobile terminal 100 and the external device.

[0065] The memory 109 can be used to store software programs and various data. The memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store the operating system, applications required for at least one function (such as sound playback, image playback, etc.), etc.; the data storage area may store data created based on the use of the mobile phone (such as audio data, phonebook, etc.). Furthermore, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0066] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 110.

[0067] The mobile terminal 100 may also include a power supply 111 (such as a battery) that supplies power to various components. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system.

[0068] although Figure 1 As not shown, the mobile terminal 100 may also include a Bluetooth module, etc., which will not be described in detail here.

[0069] To facilitate understanding of the embodiments of this application, the communication network system on which the mobile terminal of this application is based is described below.

[0070] Please see Figure 2 , Figure 2 This application provides a communication network system architecture diagram. The communication network system is an LTE system based on the universal mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and the operator's IP services 204, which are connected in sequence.

[0071] Optionally, UE201 can be the aforementioned terminal 100, which will not be described in detail here.

[0072] E-UTRAN202 includes eNodeB2021 and other eNodeB2022, etc. Optionally, eNodeB2021 can connect to other eNodeB2022 via backhaul (e.g., X2 interface), and eNodeB2021 connects to EPC203, providing access from UE201 to EPC203.

[0073] EPC203 may include MME (Mobility Management Entity) 2031, HSS (Home Subscriber Server) 2032, other MMEs 2033, SGW (Serving Gateway) 2034, PGW (Packet Data Network Gateway) 2035, and PCRF (Policy and Charging Rules Function) 2036, etc. Optionally, MME2031 is the control node that handles signaling between UE201 and EPC203, providing bearer and connection management. HSS2032 is used to provide registers to manage functions such as the Home Location Register (not shown in the figure) and stores user-specific information such as service characteristics and data rates. All user data can be sent through SGW2034. PGW2035 can provide UE 201 IP address allocation and other functions. PCRF2036 is the policy and charging control decision point for service data flow and IP bearer resources. It selects and provides available policy and charging control decisions for the policy and charging enforcement function unit (not shown in the figure).

[0074] IP services 204 may include the Internet, intranet, IMS (IP Multimedia Subsystem), or other IP services.

[0075] Although the above description uses the LTE system as an example, those skilled in the art should understand that this application is not only applicable to the LTE system, but also to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, and future new network systems (such as 5G), etc., without limitation.

[0076] Based on the above-described mobile terminal hardware structure and communication network system, various embodiments of this application are proposed.

[0077] To facilitate understanding, the application scenarios of the embodiments of this application will be introduced first.

[0078] Figure 3 This is a schematic diagram illustrating an application scenario involved in an embodiment of this application. For example... Figure 3 As shown, the application scenario of this embodiment involves two devices: one of the two devices is the source device, and the other device is the target device, and the source device and the target device perform screen projection display.

[0079] However, existing technologies require users to manually participate on the screen projection display device, which involves a long operation path and therefore suffers from low screen projection display efficiency.

[0080] To address the aforementioned technical problems, the overall inventive concept of this application is to provide a screen projection method that automatically triggers the opening of the window corresponding to the recommended application by searching for the application identifier of the recommended application in a preset database by the target device, without human intervention, thereby improving the efficiency of application screen projection.

[0081] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0082] First Embodiment

[0083] Figure 4 This is a flowchart illustrating the screen projection display method according to the first embodiment. Figure 4 As shown, the method of this embodiment, applied to the target device, includes the following steps:

[0084] S10: After establishing a screen mirroring connection with the source device, receive the device identifier and current mode sent by the source device.

[0085] In this embodiment, the source device can be referred to as the Source end, which is the end that generates user data such as audio and video during the screen projection process. Step S10 and subsequent steps in the first embodiment are all executed by the target device, which can be referred to as the Sink end, which is the end responsible for display during the screen projection process. Both the source and target devices can refer to any of the aforementioned smart terminals. The platform systems of the smart terminals include, but are not limited to, Android, Windows 8, and MeeGo systems. This embodiment does not specifically limit the platform system settings of the source and target devices. When they are different platform systems, it can be understood as achieving cross-platform and cross-device interconnection. The Source end has a main screen, and after the screen projection connection between the Source and Sink ends is successful, the behavior of the window actively opened by the Sink end corresponding to the recommended application is consistent with the behavior on the main screen of the Source end. This embodiment does not specifically limit the specific representation of the device identifier of the source device; for example, it can be a string.

[0086] It should be understood that each mode corresponds to a mode identifier. The current mode can refer to work mode, leisure mode, or other modes, but the classification of modes in this application embodiment is not specifically limited.

[0087] Optionally, the Source is a mobile phone and the Sink is a PC. Before the Sink establishes a screen mirroring connection with the Source, the Source can customize the current mode. This application provides a solution for freely switching modes on the Source to determine the current mode. This solution is described in the third embodiment below and will not be repeated here.

[0088] S20: Find the device identifier and the recommended application corresponding to the current mode in the preset database.

[0089] It should be understood that recommended applications can be understood as users' frequently used applications, and different recommended applications correspond to the same source device in different modes. Furthermore, the recommended applications can be stored in a preset database as application identifiers, and this application embodiment does not specifically limit the specific form of the application identifier; for example, it can be a string. The device identifier of the source device and the application identifier of the recommended applications are both set before this search. For example, when QQ Music and Candy Crush Saga, which a user frequently uses, are pre-set as recommended applications for the user's source device in leisure mode, the identifiers of QQ Music and Candy Crush Saga, as well as the device identifier of the source device and the mode identifier of leisure mode, are stored in the preset database to prepare data for searching for the application identifiers of recommended applications.

[0090] Furthermore, different modes correspond to different application identifiers for recommended apps. For example, the recommended app identifier for work mode is Notepad; the recommended app identifier for leisure mode is NetEase Cloud Music.

[0091] By executing S10 above, this application can ensure that in the case of multiple source devices, the device identifiers of multiple different source devices can be distinguished, and then in step S20, the application identifiers of recommended applications in the current mode of different source devices can be effectively distinguished.

[0092] S30: Open and display the recommended application.

[0093] Step S20 above retrieves the device identifier of the source device and the recommended application corresponding to the current mode from the preset database, which forms the trigger condition for opening and displaying the recommended application in step S30. By executing S30, it can be ensured that the user data displayed in the window corresponding to the opened recommended application is consistent with the user data on the main screen of the source device. Steps S10 to S30 above are all processes implemented after the interconnection between the source device and the target device is established. This application embodiment does not specifically limit the process of establishing communication between the two devices and the establishment of the data channel.

[0094] By executing S10 to S30 above, this application automatically triggers the opening and display of recommended applications by searching the source device's device identifier and the application identifier of the recommended application corresponding to the current mode in a preset database. This requires no manual intervention, reduces the user's operation path, and improves the efficiency of application projection display.

[0095] Optionally, the recommended application is an application whose usage frequency and / or usage duration in the current mode state corresponding to the device identifier reaches a preset condition.

[0096] It should be understood that the specific description of the application selection process is given in step S50 of the second embodiment below, and will not be repeated here.

[0097] Existing technologies, during screen mirroring, open an additional window displaying frequently used applications from the user recently. This has the following drawback: the recommended applications remain fixed across different scenarios, failing to meet user needs. Therefore, this application provides a novel application recommendation method that recommends different applications to the user based on changes in usage mode. For example, the preset conditions require that the application be used at least once per hour, with each use lasting at least 5 minutes. By determining recommended applications based on usage frequency and / or duration within the source device's current mode, the accuracy of the recommended applications can be guaranteed.

[0098] In other words, since the applications that users commonly use in work mode and leisure mode are completely different, the embodiments of this application allow users to select the mode on the source device side, thereby enabling the provision of recommended applications of the corresponding mode to the target device in different scenarios, thus improving the accuracy of the recommendations.

[0099] Second Embodiment

[0100] Figure 5 This is a flowchart illustrating the screen projection method according to the second embodiment. Following step S10 in the first embodiment, as... Figure 5 As shown, the method in this embodiment further includes:

[0101] S40: If the device identifier and / or the recommended application are not found in the preset database, each alternative application is displayed through the application candidate window, wherein the alternative application is an application whose usage frequency and / or usage duration in the current mode state of the source device reaches a preset condition.

[0102] In this embodiment, during the initial connection between the Source and Sink ends, a situation may arise where the device identifier and recommended application for the Source end cannot be found in the preset database. In this case, various candidate applications are displayed through an application selection window. For example, if the user selects a working mode on the Source end, and after cross-platform and cross-device interconnection is established, the Sink end automatically opens an application selection window, such as... Figure 6 As shown, the application candidate window is displayed on the Sink's desktop, and the candidate applications in the window include: Application A, Application B, Application C, and Application D. These four candidate applications are selected by the Source based on the working mode and are frequently used in this mode. The Sink displays the top-ranked applications among the candidate applications in this window. Users can select these candidate applications to confirm them as recommended applications. Recommended applications are characterized by automatically opening after the next successful connection between the Sink and the Source in the current mode. The filtering rules for the above candidate applications are determined by usage frequency and / or usage duration. Usage frequency, also known as the usage frequency, can be displayed in the form of a tppe field. This application embodiment does not specifically limit the setting of the filtering rules; it can be time-priority or usage frequency-priority. It should be noted that this application does not specifically limit the number of recommended applications.

[0103] In practical applications, applications on the source device are constantly updated. Suppose the source device is retrieving data for applications A, B, and C in the current mode, where application A was downloaded just before the current connection and has not been used. The sink device, however, already stored applications B and C corresponding to the current mode in its preset database during the last connection. Therefore, application A cannot be opened and displayed after this connection. In this situation, the user can open the application selection window and click the settings option. This allows the user to trigger the opening and display of the desired application through interactive operations even if they cannot find it among the recommended applications, thus meeting their personalized needs.

[0104] S50: In response to the recommended application selection instruction in the application candidate window, the selected application is used as the recommended application for the source device in the current mode state.

[0105] The aforementioned recommended application selection command can be understood as an icon selection command. After screen mirroring is established, this embodiment of the application displays an application selection window on the Sink desktop, allowing users to add or delete recommended applications. For example, by selecting... Figure 6 Add recommended apps using method A in the middle, by unchecking the box. Figure 6 The D method reduces the deletion of recommended applications. Through the operations described in S50, rapid management of recommended applications can be achieved.

[0106] S60: Add the device identifier and / or the recommended application to the preset database.

[0107] For example, if the user selects "Casual Mode" on the Source side, music apps such as QQ Music, Kugou, Kuwo, and NetEase Cloud Music are frequently used and can be considered as alternative apps. In this case, the Sink side's preset database pre-stores recommended apps corresponding to the current mode, thus determining which recommended app to open when the current mode is determined. If QQ Music and Kuwo are chosen as alternative apps, they are added to the preset database so that when the Sink side receives the current mode from the source device, QQ Music and Kuwo will automatically open simultaneously, and both recommended apps will be displayed on the same screen.

[0108] By executing S40 to S60, the embodiments of this application enable users to select recommended applications of interest from alternative applications according to their personal needs, thereby improving the user experience.

[0109] Optionally, in step S40, displaying each of the candidate applications through the application selection window includes the following steps S401 to S402, wherein:

[0110] S401: Sort the candidate applications in descending order of usage frequency and / or usage duration of the source device in the current mode state.

[0111] S402: Display each of the candidate applications in the application selection window according to the sorting result.

[0112] By executing S401, this embodiment of the application refines the selection process of alternative applications. By executing S402, this embodiment of the application enables alternative applications to be displayed in an orderly manner in the application selection window.

[0113] Optionally, after step S10, the method further includes:

[0114] S70: Identify applications whose usage frequency and / or usage duration are less than the hiding threshold when the source device corresponding to the device identifier is in the current mode state as hidden applications;

[0115] S80: Hide the application icon of the hidden application on the desktop.

[0116] This application embodiment does not specifically limit the hiding threshold. By executing operations S70 to S80, the desktop display can be made simpler.

[0117] Optionally, the method further includes:

[0118] S90: In response to the hide cancellation operation, the application icon of the hidden application is displayed on the desktop.

[0119] In this embodiment, the hide cancellation operation can be performed by the user through an input device. The input device can refer to a keyboard, remote control, or similar device. This embodiment allows the user to display the application icon of the hidden application on the desktop through the hide cancellation operation, thus preparing for opening and displaying the hidden application corresponding to that icon, meeting user needs.

[0120] Third Embodiment

[0121] Figure 7 This is a flowchart illustrating the screen projection method according to the third embodiment. This embodiment applies to a source device, and the screen projection method includes:

[0122] S100: In response to the mode selection instruction, the current mode is determined. Optionally, after determining the current mode, the source device can filter out candidate applications from the existing applications of the source device. The process of filtering candidate applications is described in S101 to S104 below, and will not be repeated here.

[0123] S200: After establishing a screen mirroring connection with the target device, send the device identifier of this device and the current mode to the source device.

[0124] In this embodiment, the source device can package its device identifier and current mode. This packaging transforms normal data into data that can be transmitted over a network. By executing the operations S100 to S200, this application can determine the current mode of the source device, thereby providing data support for the target device to automatically open and display recommended applications corresponding to the current mode when the source device is in that mode.

[0125] Optionally, the method further includes:

[0126] S300: Send to the target device the usage frequency and / or usage duration of each application when the device is in the current mode state.

[0127] By executing S300, on the one hand, the embodiments of this application can realize the selection of alternative applications and the selection of recommended applications on the target device, thereby reducing the processing pressure of the source device and improving the processing speed.

[0128] Optionally, step S100 includes the following steps:

[0129] S101: In response to a screen mirroring trigger operation, display a mode configuration interface containing icons for at least two modes.

[0130] In this embodiment, the source can select a mode through a mode configuration interface, which also provides a brief description of the two modes and their differences. The mode configuration interface is as follows: Figure 8 As shown, the current modes can be broadly categorized into two types: work mode and leisure mode.

[0131] S102: In response to a mode selection instruction triggered based on the mode configuration interface, select the mode corresponding to the mode selection instruction as the current mode.

[0132] It should be understood that, based on user... Figure 8 After selecting the current mode and turning on the corresponding switch in the mode configuration interface, the Sink end, after establishing a screen mirroring connection with the Source end, displays recommended applications corresponding to the current mode. Specifically, for example... Figure 8As shown, after the user turns on the "Open recommended interface after screen mirroring" switch, the target device can automatically open recommended applications. There are two switches under mode selection: one for turning work mode on or off, and the other for turning leisure mode on or off. In work mode, if screen mirroring is successful, the target device automatically recommends opening office software such as document editing, email, and notepad; in leisure mode, if screen mirroring is successful, the target device automatically recommends opening entertainment software such as music and games. In this embodiment, the modes are represented by switches for easy user selection.

[0133] After S102 is executed and before S300 is executed, the method reports the following:

[0134] S103: Select the application in the current mode as the alternative application.

[0135] S104: Obtain the usage frequency and / or usage duration of the candidate application when the source device is in the current mode state.

[0136] S105: Based on the usage frequency and / or usage duration, sort all the candidate applications to obtain the application sorting result, and select candidate applications from the application sorting result.

[0137] This application embodiment executes S101 to S105, mainly by obtaining data of the candidate applications over a period of time through an interface similar to States on the Source side. Then, according to the sorting rules, that is, according to the usage frequency and / or usage duration, a data cleaning is performed, which can provide corresponding candidate applications for the current mode selected by the user, thereby improving the accuracy of the candidate applications recommended to the application candidate window of the target device.

[0138] Fourth embodiment

[0139] Figure 9 This is a flowchart illustrating the screen projection display method according to the fourth embodiment. Figure 9 As shown, the screen projection method includes the following steps:

[0140] S1: Establishes a connection and data transmission channel between the Source and Sink ends.

[0141] It should be understood that, for the Source side, the following steps S2 to S5 are executed: S2: Enter the mode configuration interface; S3: Select the current mode; S4: Obtain the application's usage frequency and / or usage duration within a preset time period; S5: Organize, package, and send the data.

[0142] For the Sink end, execute the following steps S6 to S15, where S6: Receive and parse data.

[0143] S7 searches for the device identifier of the Source in the preset database. If the device identifier is found, S8 is executed; otherwise, S14 is executed.

[0144] S8: Search the preset database for recommended applications corresponding to the current mode. If a recommended application corresponding to the current mode is found, execute S15; otherwise, execute S9.

[0145] S9: Display the application selection window.

[0146] S10: Receive click action; S11: Open and display the application.

[0147] S12: Determine if a checkbox command has been received; if yes, execute S13; otherwise, end.

[0148] S13: Store recommended apps in a preset database so that they will open automatically on the next connection;

[0149] S14: Add a new device identifier; and after the addition operation is completed, continue to execute S9.

[0150] S15: Open and display recommended applications. The specific implementation process of this method can be found in the previous three embodiments, and will not be repeated here.

[0151] In summary, after the initial screen mirroring connection between the target device and the source device, the Sink automatically pops up an application selection window. Users can select applications by triggering a checkbox command. These selected applications will be automatically opened as recommended applications upon the next screen mirroring connection. In other words, after the user selects applications, this data, along with the source device identifier (such as device ID) and mode identifier, is saved to the Sink's preset database. Upon the next connection, the Sink compares the source device identifier to confirm a match. If a match is found, it retrieves the application identifier of the recommended application corresponding to the current mode from the preset database. If the application is found, it opens and displays the recommended application.

[0152] It should be understood that the execution flow of this screen casting method allows users to freely select the mode on the Source side, while the recommended application can be automatically opened and displayed on the Sink side, thereby achieving the beneficial effect of reducing the operation path when users cast recommended applications.
