The screen projection transmitting device may establish a communication channel based on a preset communication Protocol, such as a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), and the like, and transmit the screen projection data to the screen projection receiving device through the communication channel, so that the screen projection receiving device can display the screen projection data. The electronic device that sends the screen projection data may be referred to as a screen projection transmitting device, such as a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, and so on; an electronic device that receives and displays the projection screen data may be referred to as a projection screen receiving device, such as a projector, a kiosk, a television, a Personal Computer (PC), a notebook Computer, a tablet Computer, or the like; the screen projection data comprise data of a display window in the screen projection transmitting equipment, real-time operation data and the like. In some possible implementations, the screen projection method may be implemented by a processor calling computer readable instructions stored in a memory.

Fig. 1 shows a flowchart of an information processing method provided by an embodiment of the present disclosure, and as shown in fig. 1, the method includes the following steps:

s11, screen projection information is obtained; the screen projection information comprises a screen projection time period;

s12, in the screen projection process, determining whether the current time is in the screen projection time period;

s13, outputting prompt information when the current time is not within the screen-casting time period;

s14, responding to the received instruction for indicating whether the screen projection is finished or not acquired based on the prompt information, and executing operation matched with the instruction; wherein the operation comprises one of: and finishing screen projection and continuing to project the screen.

In the embodiment of the present disclosure, the screen projection transmitting device executes step S11, and acquires screen projection information including a screen projection time period before starting screen projection or in a screen projection process, where the screen projection time period represents a time period in which screen projection can be performed, and one or at least two of the time periods may be used, and each screen projection time period corresponds to a screen projection start time and a screen projection end time.

The screen-casting information is acquired, wherein the screen-casting information including the screen-casting time period input by a user is received by the screen-casting transmitting equipment, or the screen-casting information including the screen-casting time period is acquired from a conference reservation system after other systems are docked, such as a conference reservation system; the conference reservation system can be used for reserving information such as conference places, participants and screen-throwing time periods.

In step S12, in the screen projecting process, the screen projecting transmitting device determines whether the current time is within the screen projecting time period, and performs step S13 according to the determination result whether the current time is within the screen projecting time period, and outputs the prompt information if the current time is not within the screen projecting time period. The current time is not in the screen-projecting time period, and the current time does not fall into any screen-projecting time period.

In the embodiment of the disclosure, the screen projection transmitting device may output the prompt information on the screen projection transmitting device, or send the prompt information to the screen projection receiving device or other devices (such as a terminal communicating with the screen projection transmitting device) for output, and the like, when determining that the current time is not within the screen projection time period. When the prompt message is output, the prompt message can be output in different manners, for example, the prompt message is output in a text display manner or in a voice manner; or outputting prompt information of different contents, for example, outputting prompt information representing that the screen is not currently projected in a screen projection time period, or outputting prompt information representing that the screen is projected later than the screen projection starting time at present, and outputting prompt information representing whether the screen projection is finished or not later than the screen projection finishing time at present; the prompt information can also be output in different display forms, such as displaying text information in a popup window form at the lower right corner of the screen projection interface, displaying voiceprints in the center of the screen projection interface and correspondingly playing voice and the like. In addition, the prompt information of different contents may also be output in combination with the different manners and the different display forms, which is not limited in the embodiment of the present disclosure.

In the embodiment of the present disclosure, the prompt information may further include a control for ending the screen projection and a control for continuing the screen projection. Therefore, the user can select whether to finish screen projection or not by selecting the control in the prompt message based on the prompt message directly.

It should be noted that, if the prompt information is displayed on the screen projection transmitting device, the screen projection transmitting device may directly detect a selection instruction of a control (including a control representing that screen projection is finished and a control representing that screen projection is continued) in the prompt information, so as to improve the instantaneity of the screen projection transmitting device in obtaining the instruction, and further improve the instantaneity of subsequent screen projection continuation or screen projection stop based on the obtained instruction.

If the prompt information is displayed on the screen projection receiving equipment, the screen projection receiving equipment sends the selected instruction to the screen projection transmitting equipment after detecting the selected instruction of the control in the prompt information, and therefore the screen projection transmitting equipment can obtain the selected instruction. Because the content displayed by the screen projection receiving equipment is often checked by a plurality of people, the number of people checking the prompt information can be increased and the prompt effect is enhanced by the scheme. In addition, the prompt information can be displayed on the screen projection transmitting device and the screen projection receiving device at the same time, which is not limited by the disclosure.

In the embodiment of the present disclosure, in step S14, in the case that an instruction representing whether to finish screen projection is received, where the instruction is acquired based on the prompt information, the screen projection transmitting device performs an operation matched with the instruction, where the operation includes finishing screen projection and continuing screen projection. For example, if the instruction is an instruction for indicating that screen projection is finished, the screen projection transmitting device executes screen projection finishing, and stops sending screen projection data to the screen projection receiving device, so that the screen projection receiving device stops displaying the screen projection data; if the instruction is an instruction for representing continuous screen projection, the screen projection transmitting equipment executes continuous screen projection and continuously sends screen projection data to the screen projection receiving equipment for displaying.

It can be understood that, in the embodiment of the present disclosure, the screen projection transmitting device acquires the screen projection information including the screen projection time period, and in the screen projection process, under the condition that it is determined that the current time is not within the screen projection time period, the prompt information is output, so that it is not necessary for the user to frequently check the current time to determine whether the current time is within the screen projection time period, and the instantaneity of the user in learning that the current time is not within the screen projection time period is improved. In addition, the screen projection transmitting equipment stops sending screen projection data to the screen projection receiving equipment under the condition that an instruction for representing finishing screen projection is received based on the prompt information, so that the waste of screen projection resources and information leakage caused by the fact that the screen projection transmitting equipment still sends the screen projection data to the screen projection receiving equipment for displaying when screen projection is not needed can be reduced; and the screen projection transmitting equipment continues to project the screen under the condition of receiving an instruction for representing the continuation of screen projection based on the prompt information, so that the inconvenience brought to a user by forcibly stopping screen projection when the screen projection ending time is reached can be reduced.

Fig. 2 shows an example of an interface for outputting prompt information according to an embodiment of the present disclosure, in fig. 2, the screen-shot content is screen-shot data being displayed on the screen-shot receiving device, and in a case that the current time is not within the screen-shot time period, a pop-up window is set to output a prompt message identified by a 1. The prompting message identified by A1 comprises prompting content, the control identified by P1 corresponds to the control representing the end of screen projection, and the control identified by P2 corresponds to the control representing the continuation of screen projection. Wherein, the prompt content includes "to arrive at the meeting appointment ending time, do it need to end the screen projection? ", the conference reservation end time corresponds to the screen-casting end time included in the screen-casting time period. Since the current time has reached the conference reservation end time, it is desirable for the user to end the screen-casting to release the screen-casting resource, and therefore the control identified by P1 in fig. 2 is highlighted to guide the user in selecting the end of the screen-casting.

After the user clicks the control identified by the P1, the screen projection transmitting equipment receives an instruction for representing the end of screen projection, and then stops sending screen projection data to the screen projection receiving equipment; after the user clicks the control identified by the P2, the screen projection transmitting device receives an instruction for representing continuous screen projection, closes the popup window identified by the A1 where the prompt message is located, and continuously sends screen projection data to the screen projection receiving device for display.

It can be understood that when the current time reaches the conference appointment ending time, the prompt information is output, so that the instantaneity of the user in learning that the current time is not in the screen-casting time period can be improved; in addition, the prompt information comprises a prompt text and a control, so that a user can directly select whether to finish screen projection based on the prompt information, convenience is improved, screen projection is stopped when the user selects to finish screen projection, and waste of screen projection resources is reduced.

In some embodiments, the performing, in response to receiving an instruction representing whether screen projection is finished or not acquired based on the prompt information, an operation matched with the instruction includes:

and under the condition that the instruction represents that the screen is continuously projected, outputting the prompt information at preset time intervals.

In the embodiment of the disclosure, if a user inputs an instruction representing continuing to screen on the device outputting the prompt information based on the prompt information, the screen projection transmitting device continues to send screen projection data to the screen projection receiving device for displaying after acquiring the instruction, and outputs the prompt information after a preset time interval. If a user inputs a command representing ending screen projection on the equipment outputting the prompt information based on the prompt information, the screen projection transmitting equipment stops transmitting screen projection data to the screen projection receiving equipment; if the user inputs the instruction for representing continuous screen projection again on the device for outputting the prompt information based on the prompt information, the screen projection transmitting device continues to transmit screen projection data to the screen projection receiving device for displaying, and outputs the prompt information again after the preset time interval until the user inputs the instruction for representing ending screen projection.

It should be noted that the preset time duration may be defined by the user at the screen projection transmitting end, or may be default (e.g. 15 minutes), and if the preset time duration is too long (e.g. 2 hours), the effect of immediately reminding the user may not be achieved; if the duration is set to be too short (for example, 1 minute), the situation that prompt information is frequently output exists, and the user experience is poor. Therefore, the setting of the preset duration needs to consider both the instantaneity of the output of the prompt message and the user experience.

It can be understood that, in the case that the instruction for representing continuous screen projection is obtained based on the prompt information, the prompt information is output again to inquire whether the user finishes screen projection after the preset duration of continuous screen projection is received, and the prompt information is output for multiple times after the preset duration of the interval.

In some embodiments, the method further comprises:

displaying a first interface comprising a first control for indicating a screen projection mode in a screen projection process;

in response to detecting an operation instruction on the first control based on the first interface, determining a target screen projection mode;

The user may select a screen-casting mode by operating a first control based on the displayed first interface.

In the embodiment of the disclosure, the screen projection transmitting device determines a target screen projection mode based on the first interface detecting an operation instruction of a user on the first control. For example, the screen projection transmitting device detects that the operation instruction of the user on the first control based on the first interface may be a click instruction on the first control, or receives a voice instruction including a name of the first control, and determines the screen projection mode corresponding to the first control indicated by the operation instruction on the first control as the target screen projection mode.

In the embodiment of the disclosure, after determining the target screen projection mode, the screen projection transmitting device determines whether the target screen projection mode is consistent with the current screen projection mode. Under the condition that the target screen projection mode is consistent with the current screen projection mode, continuing to project the screen in the current screen projection mode; and under the condition that the target screen projection mode is inconsistent with the current screen projection mode, switching the current screen projection mode into the target screen projection mode, and sending screen projection data corresponding to the target screen projection mode to screen projection receiving equipment for displaying.

In the embodiment of the disclosure, in the screen projection process, the target screen projection mode is determined based on the operation instruction of the first control detected by the first interface, and under the condition that the current screen projection mode is inconsistent with the target screen projection mode, the screen projection mode can be switched to be the target screen projection mode in real time, and the user does not need to initiate screen projection based on the intention screen projection mode again after finishing the current screen projection mode manually. Through the scheme of this embodiment, can improve and throw the convenience that the in-process switched the mode of throwing the screen.

In the embodiment of the present disclosure, the first screen projection mode may be a mirror image screen projection mode; and under the condition that the target screen projection mode is the first screen projection mode, the screen projection transmitting equipment transmits the data of the window displayed in real time as screen projection data to the screen projection receiving equipment for displaying. The window is a window opened by the screen projection transmitting device, such as a window where a document file is located, a window where a browser is located, a window where a chat tool is located, and the like. The data of the window displayed in real time includes data displayed in real time in the window, data operated in real time in the window, and the like.

Illustratively, if the window displayed in real time is the window where the browser is located, the screen projection transmitting device sends data of the window where the browser is located to the screen projection receiving device as screen projection data, and the screen projection receiving device receives the screen projection data and then displays the data of the window where the browser is located in the screen projection transmitting device; at the moment, if a user opens the document file at the screen projection transmitting equipment, the window displayed in real time is the window where the document file is located, the screen projection transmitting equipment sends data of the window where the document file is located to the screen projection receiving equipment as screen projection data, and after the screen projection receiving equipment receives the screen projection data, the data of the window where the document file is located in the screen projection transmitting equipment are displayed.

It can be understood that, in the embodiment of the present disclosure, if the target screen projecting mode is the first screen projecting mode, the screen projecting transmitting device determines the data of the window displayed in real time as the screen projecting data, and sends the screen projecting data to the screen projecting receiving device for displaying in real time, so that a user can view the data displayed in real time by the screen projecting transmitting device on the screen projecting receiving device in real time, and the synchronism of the content displayed by the screen projecting receiving device and the screen projecting transmitting device is improved.

So that the user can select the window to be screened based on the displayed third interface. Each window in the third interface may be displayed in a list form, a grid form, or in different colors, which is not limited in this disclosure.

In the embodiment of the invention, the screen projection transmitting equipment sends the data of the window indicated by the first selected instruction as the screen projection data to the screen projection receiving equipment for displaying under the condition that the first selected instruction for each window is detected based on the third interface.

Fig. 3 is a diagram illustrating an example of a display interface for selecting a screen projection window according to an embodiment of the present disclosure, where in fig. 3, an interface identified by W0 corresponds to the aforementioned third interface displayed in the case that the target screen projection mode is the second screen projection mode; the windows marked by W1-W4 are windows 1-4 respectively, and correspond to the windows in the third interface. Wherein, the window identified by W1 corresponds to the control identified by J1, the window identified by W2 corresponds to the control identified by J2, the window identified by W3 corresponds to the control identified by J3, and the window identified by W4 corresponds to the control identified by J4. The user can send a first selection instruction to the control corresponding to the window which is intended to be subjected to screen projection based on the interface identified by the W0, so that the screen projection transmitting device detects the first selection instruction to the window based on the third interface, and sends the data of the window indicated by the first selection instruction as screen projection data to the screen projection receiving device for displaying. By the scheme, the purpose of the screen projection data can be improved.

It should be noted that, if the window indicated by the first selection instruction is a window, the screen projection transmitting device may send the data of the indicated window as screen projection data to the screen projection receiving device for displaying.

By the scheme, the user can be helped to quickly select the screen projection receiving equipment, and the screen projection initiating efficiency is improved.

In the embodiment of the disclosure, the user may select the screen projection receiving device to be projected based on the displayed second interface.

In the embodiment of the disclosure, the screen projection transmitting device sends the screen projection data to the screen projection receiving device indicated by a second selected instruction for displaying based on the target screen projection mode under the condition that the second selected instruction of the screen projection receiving device is detected based on the device identifier in the second interface; the screen projection receiving device indicated by the second selection instruction may be one or multiple.

It can be understood that, in the embodiment of the present disclosure, before the screen projection is started, the screen projection transmitting device displays a second interface including the second control and the device identifiers of the at least two screen projection receiving devices, and based on a second selection instruction of the user screen projection receiving device, the screen projection data is sent to the screen projection receiving device indicated by the second selection instruction for display, so that the purpose of determining the screen projection receiving device can be improved.

It should be noted that, if the screen projection information includes an equipment identifier of one screen projection receiving device, the second interface displays the equipment identifier of one screen projection receiving device, and sets the equipment identifier to the selected state. According to the scheme, the screen projection receiving equipment does not need to be selected by a user, and after the user initiates screen projection, the screen projection transmitting equipment can directly send screen projection data corresponding to the target screen projection mode to the screen projection receiving equipment corresponding to the equipment identification in the selected state for screen projection.

The screen projection code can be generated by the screen projection receiving equipment or generated by the server for each screen projection receiving equipment, and the generated screen projection code can uniquely indicate the screen projection receiving equipment due to uniqueness of the screen projection code.

The screen projection transmitting device in the embodiment of the disclosure acquires the screen projection code under the condition that the operation instruction of the third control is detected based on the second interface. For example, the screen projection transmitting device may obtain a screen projection code input by a user on the screen projection transmitting device based on detecting an input instruction to a text input control indicating the screen projection code; acquiring voice information based on the detection of a selected instruction of a voice receiving control for indicating the screen projection code, and further analyzing the screen projection code by utilizing technologies such as voice recognition and the like; based on the detection of the selected instruction of the scanning control for indicating the screen-projecting code, the screen-projecting code is obtained by scanning a two-dimensional code or Optical Character Recognition (OCR) and the like. The screen projection receiving equipment can display the screen projection code, so that a user can input the screen projection code on a second interface which is displayed by the screen projection transmitting equipment and comprises a third control based on the displayed screen projection code, or the screen projection receiving equipment can display a two-dimensional code, and the user can scan the two-dimensional code and the like through the third control. In addition, the screen projection transmitting device may also receive screen projection codes sent by other terminals, which is not limited in this disclosure.

After the screen projection transmitting equipment acquires the screen projection code, screen projection data are sent to screen projection receiving equipment indicated by the screen projection code for display based on a target screen projection mode. If the screen projection receiving equipment indicated by the acquired screen projection code does not exist, the screen projection transmitting equipment can output information representing that the screen projection receiving equipment is not found or output information representing that the screen projection code is wrong so as to remind a user of re-inputting the screen projection code.

It can be understood that, in the embodiment of the present disclosure, the screen projection transmitting device sends the screen projection data to the screen projection receiving device indicated by the screen projection code in a screen projection code manner for display, and the screen projection transmitting device and the screen projection receiving device do not need to be in wired connection, and the screen projection transmitting device and the screen projection receiving device do not need to be connected to the same wireless local area network, so that the screen projection application range is greatly widened.

In the embodiment of the disclosure, the screen-projecting code of the screen-projecting receiving device can be uniquely identified, and the screen-projecting code can be automatically updated every time the updating duration (for example, 5 minutes) is preset. Through the scheme, the problem of malicious screen projection caused by the fact that the screen projection code is fixed and unchanged can be reduced, and smooth screen projection is guaranteed.

It should be noted that, in the embodiment of the present disclosure, the screen projection receiving device may be determined based on the screen projection code, or the screen projection receiving device may be determined based on the detection of the second selected instruction in the second interface. In addition, the screen projection receiving equipment and the screen projection code can be combined to jointly determine the screen projection receiving equipment, and if the screen projection receiving equipment indicated by the screen projection code is consistent with the screen projection receiving equipment determined based on the second selected instruction, screen projection can be started, malicious screen projection initiated by the known screen projection code can be reduced, and the accuracy and the safety of screen projection are improved.
