The newly added prompt information can comprise a corresponding identification input control or identification selection control and the like, so that a user can input or select at least one receiving end identification.

In some embodiments, after the server determines multiple receiving ends in response to the screen-throwing request, a first screen-throwing notification may be further sent to the multiple receiving ends, where the receiving ends are further configured to switch to a screen-throwing receiving state in response to the first screen-throwing notification.

For example, the screen content is generally transmitted through a websocket channel, and in a screen receiving state, the websocket channel can be started.

In some embodiments, in order to improve the transmission performance, as shown in fig. 3, the server may include afirst server 301 and asecond server 302, which are different from those shown in fig. 1;

the screen-throwingend 101 specifically sends a screen-throwing request to thefirst server 301;

Thefirst server 301 is configured to determine a plurality of receiving ends 102 based on the screen-drop request, and send a first screen-drop notification to the plurality of receiving ends 102 respectively;

the receivingend 102 switches to a screen receiving state in response to the first screen projection notification, specifically, establishes a connection channel with thesecond server 302 in response to the screen projection notification;

the screen-throwingend 101 is specifically configured to send screen-throwing content to thesecond server 302;

thesecond server 302 is configured to forward the screen content to the plurality of receiving ends 102 respectively.

I.e. the second server is responsible for the receipt and forwarding of the screen-cast content. The first server is responsible for negotiating with the screen throwing end and the receiving end.

Wherein in some embodiments, the server further comprises a third server, and the receiving end comprises a first receiving end installed in the first terminal or a second receiving end installed in the second terminal; the first terminal is fixedly arranged in a fixed place; the second terminal comprises a personal terminal;

the first server sending the screen projection notification to the plurality of receiving ends respectively includes: for a first receiving end in the plurality of receiving ends, sending a first screen projection notification to the first receiving end; and aiming at a second receiving end in the plurality of receiving ends, sending the first screen projection notification to the second receiving end through the third server.

The first terminal is fixedly arranged in a fixed place, and the first receiving end and the first server can keep a long connection state, so that the first server can directly send the first screen projection notification to the first receiving end.

The second receiving end can be connected with the server without maintaining a long connection state, and the connection can be established when the second receiving end is required, so that the first server can firstly send the first screen-throwing notification to the third server aiming at the second receiving end, and the third server firstly establishes network connection with the user end and then sends the first screen-throwing notification to the user end.

Optionally, the second receiving end responds to the first screen projection notification and can output receiving prompt information; based on the corresponding triggering operation of the user, sending a confirmation request or a rejection request to the server;

the third server is further configured to receive a confirmation request fed back by the second receiving end, and send a screen-throwing confirmation instruction to the second server; receiving a rejection request fed back by the second receiving end, and sending a screen-throwing termination instruction to the second server;

the second server is further configured to forward the screen-cast content to the first receiving end and a second receiving end with a screen-cast confirmation indication.

In some embodiments, the server is further configured to send a second screen-drop notification to the plurality of receiving ends respectively;

the receiving end is also used for responding to the second screen projection notification and outputting receiving prompt information; based on the corresponding triggering operation of the user, sending a confirmation request or a rejection request to the server;

the step of forwarding the screen projection content to the plurality of receiving ends by the service end comprises the following steps: receiving a confirmation request sent by any receiving end, and forwarding the screen projection content to the receiving end; and receiving a rejection request sent by any receiving end, and canceling forwarding the screen-casting content to the receiving end.

Optionally, after receiving the confirmation request of any receiving end, the server may send a confirmation instruction to the screen-throwing end, so that the screen-throwing end may send the screen-throwing content to the server in response to the confirmation instruction.

The screen projection prompt information is used for prompting whether a receiving end user allows screen projection or not. When the receiving end is a user end, the server end can send a second screen projection notification to the receiving end so as to trigger the client end to output screen projection prompt information because the second screen projection notification is configured in the personal terminal so as to ensure safety and enable the receiving end user to timely receive the screen projection content.

The receiving prompt may include one or more of a content prompt, a vibration prompt, and a ringing prompt.

The vibration prompt information can be realized by starting a motor component of the terminal where the receiving end is located, the ringing prompt information can be realized by a loudspeaker component of the terminal where the receiving end is located, and the like. The content prompt information can include information related to the screen throwing end, such as the name of the user of the screen throwing end.

The receiving end user can also execute corresponding triggering operations based on the receiving prompt information, for example, the content prompt information can comprise a confirmation control and a rejection control, a confirmation request can be generated by triggering the confirmation control, a rejection request can be triggered by triggering the rejection control, and the like.

In addition, since the receiving end may be in a certain working state, for example, receiving a screen, performing audio/video communication, etc., in some embodiments, the server may be further configured to detect whether the plurality of receiving ends are in a target working state; for a receiving end in a target working state, sending preemption prompt information to a screen throwing end;

the server-side forwarding the screen-casting content to the plurality of receiving terminals respectively comprises: the screen throwing end is detected to be aimed at the preemption confirmation request of any receiving end, and the screen throwing content is forwarded to the receiving end; and detecting a preemption rejection request of the screen throwing end for any receiving end, and canceling forwarding the screen throwing content to the receiving end.

The screen throwing end is also used for outputting the preemption prompt information; and responding to the preemption confirmation operation, sending the preemption confirmation request to the server, responding to the preemption cancellation operation, and sending the preemption cancellation request to the server.

The target working state can be that screen throwing is being received or audio and video communication is being carried out.

After the server side responds to the screen-throwing request and determines the plurality of receiving ends, whether the plurality of receiving ends are in a target working state or not can be detected first, for the receiving ends which are not in the target working state, screen-throwing content can be forwarded to the receiving ends, and for the receiving ends which are in the target working state, the screen-throwing ends can be notified first. The preemption prompt information output by the screen throwing end can be used for prompting whether the screen throwing end user continues to perform screen throwing operation to the receiving end in the target working state or not. The preemption prompt information can comprise a preemption confirmation control and a preemption cancellation control, wherein preemption confirmation operation can be initiated for the preemption confirmation control, preemption cancellation operation can be initiated for the preemption cancellation control, and the like.

As can be seen from the above description, the receiving end may accept or reject the screen projection, etc., so in some embodiments, the service end is further configured to detect the receiving states of the plurality of receiving ends for the screen projection content, and send receiving state prompt information of the plurality of receiving ends to the screen projection end;

The screen projection end is further used for displaying receiving state prompt information of the plurality of receiving ends on the first screen projection interface respectively.

The receiving state may include, for example, waiting for a screen to be cast, rejecting a screen to be cast, being cast or not being cast, etc., so as to facilitate which receiving ends of the screen casting end user are sharing the screen casting content, etc. The waiting for the screen to be displayed may be pointing to a state of the receiving end in a second preset time after the receiving end sends the screen display notification; the non-screen-throwing state may be a state that the receiving end is not received the confirmation request or refuses the request after a second preset time elapses after the screen-throwing notification is sent; the rejection of the screen shot may be a state in which the rejection request is received within a second predetermined time after the screen shot notification is sent to the receiving end. The on-screen state may refer to a state of receiving a confirmation request from the receiving end and forwarding the on-screen content to the receiving end.

For a receiving end which is in the state of rejecting screen throwing or not receiving, based on a screen throwing end user request, the screen throwing request for the receiving end and the like can be sent to the server again.

In addition, when the screen throwing end and the receiving end are in different places, the user of the screen throwing end and the user of the receiving end also have voice communication requirements, so that as an alternative way, the screen throwing end is also used for acquiring first audio data played by a terminal where the screen throwing end is located and/or the acquired second audio data; the first audio data and/or the second audio data are respectively sent to the server;

The server is further configured to forward the first audio data and/or the second audio data to the plurality of receiving ends respectively;

the receiving end is also used for playing the first audio data and/or the second audio data.

The first audio data may be data played by a speaker or an external sound box, and the second audio data may be data collected by a microphone.

In an actual application, the technical scheme of the embodiment of the application can be applied to a conference scene. In practical application, there is a requirement that users in different meeting places hold a meeting and need to share data such as files, but in addition, if the meeting room is very large, the content is thrown to the meeting terminal such as an intelligent television in the meeting room according to the existing method, the users sitting at the back cannot see clearly, so that the meeting requirement cannot be met.

According to the technical scheme of the embodiment of the application, the purpose of screen projection at a plurality of receiving ends can be achieved, and the screen projection at different places can be achieved, so that the screen projection method is not limited to the fact that the screen projection end and the receiving end are located in the same local area network, and various screen projection requirements are met.

As shown in fig. 4a, a schematic view of a screen implementation in a conference scenario is shown, comprising 4 conference sites in fig. 4: site a, site B, site C, and site D; where, the site a is a conference room in which theconference terminal 41 is disposed, the site B is a conference room in which theconference terminal 42 is also disposed. The user at location C corresponds to apersonal terminal 43, such as a cell phone, and the user at location D corresponds to apersonal terminal 44, such as a notebook computer.

The screen-throwingend 45 of the user at the site a and theconference terminal 41 are in the same local area network, and can establish a point-to-point connection channel with theconference terminal 41, so as to throw screen-throwing content into theconference terminal 41.

The screen-throwingend 45 can establish a remote connection channel with theconference terminal 42, thepersonal terminal 43 and thepersonal terminal 44 through theservice end 46, wherein for a user with a site a far from theconference terminal 42, a remote connection channel can also be established with the correspondingpersonal terminal 47. Therefore, thescreen throwing end 45 can send the screen throwing content to theservice end 46, and theservice end 46 forwards the screen throwing content to theconference terminal 42, thepersonal terminal 43, thepersonal terminal 44 and thepersonal terminal 47, so that the purposes of throwing multiple screens and throwing the screen in different places are achieved.

In addition, since there may be a voice communication requirement between the user at the screen-throwing end and the user at the receiving end in the case of the screen-throwing in a different place, the user at the screen-throwing end may select the target receiving end with the voice communication requirement, and send a call request to theserver 46 through the screen-throwingend 45, where the call request and the screen-throwing request may be sent simultaneously, as shown in fig. 4b, theserver 46 may establish a call channel between the first phone number corresponding to the first communication terminal and the at least one second phone number corresponding to the second communication terminal through thePSTN system 48 based on the first phone number corresponding to the screen-throwing end and the second phone number corresponding to the receiving end. The PSTN system may initiate a call request by the first communication terminal and the at least one second communication terminal, respectively. The first communication terminal and the second communication terminal may refer to, for example, a fixed communication terminal such as a landline or a mobile communication terminal such as a mobile phone or the like. As shown in fig. 4b, the first communication terminal may refer to abase unit 49 of the conference room where thescreen terminal 41 is located, the second communication terminal may include abase unit 50 of the conference room where theconference terminal 42 is located, thepersonal terminal 43, amobile communication terminal 51 of a user corresponding to thepersonal terminal 44, and the like.

In addition, in order to ensure the screen-throwing timeliness in the case that the receiving terminal is a personal terminal, as shown in fig. 5, after the screen-throwingterminal 51 sends a screen-throwing request to theserver 52, theserver 52 may send a screen-throwing notification to the receivingterminal 53, and the receivingterminal 53 outputs a receiving prompt message to prompt the user whether to accept the screen throwing.

The receivingend 53 may transmit a confirmation request to theservice end 52 in response to a confirmation operation by the user.

Theserver 52 may only detect that there is a confirmation request from any receiving end, and may feed back a confirmation instruction to the screen-throwingend 51;

so that the screen-throwingend 51 responds to the confirmation instruction, after the screen-throwing content can be sent to theserver 52, if theserver 52 detects that the confirmation request exists, the screen-throwing content is forwarded to the receivingend 53.

Fig. 6a shows a display schematic diagram of a first screen-throwing interface of a screen-throwing end in an actual application, where it can be known that the first screen-throwing interface may include a first screen-throwingswitching control 61 and a second screen-throwingswitching control 62, and for a triggering operation of the first screen-throwingswitching control 61, a first screen-throwingprompt message 63 may be displayed in the first screen-throwing interface, for example, the first screen-throwingprompt message 63 may include an identification input control, and may further include one or more receiving end identifications matched with a user, so that the user may conveniently and quickly select a receiving end identification from the first screen-throwing prompt message. The one or more recipient identifications may be recommended in conjunction with a history of use of the user at the cast end, an organization in which the user at the cast end is located, and so on.

A screen-drop trigger control 64 may also be displayed in the first screen-drop interface, for example, for a click operation of the screen-drop trigger control, a screen-drop terminal may be triggered to initiate a screen-drop request to the server terminal.

In addition, as shown in fig. 6b, the difference from fig. 6a is that acall synchronization control 65 may also be displayed in the first screen-throwing interface, and after the screen-throwing end is triggered to detect the screen-throwing triggering operation for the selection operation of thecall synchronization control 65, a communication request for communication numbers corresponding to the multiple receiving end identifiers may be simultaneously sent to the server.

Of course, the call synchronization control may also be used for the user to select at least one target receiving end identifier from the provided multiple receiving end identifiers, so that the communication request may only be directed to the at least one target receiving end identifier.

Fig. 6c shows a display schematic diagram of a first screen-throwing interface after a screen-throwing request is initiated, in which the plurality of receiving end identifiers and receiving status prompt information corresponding to each receiving end identifier may be displayed, as can be seen in fig. 6c, the receiving status prompt information may include: screen on, waiting for screen on, rejecting screen on, not on, etc. Different receiving end identifiers can be used for grouping display lamps according to different receiving states.

In addition, because the communication request can be initiated simultaneously, communication state prompt information and the like of the communication numbers corresponding to the different receiving end identifiers can be displayed in the first screen projection interface. The communication status prompt may include, for example, waiting for answer, talking, rejecting answer, not answering, etc.

In addition, a screen throwing termination control for each receiving end identifier can be displayed in the first screen throwing interface, so that a screen throwing termination request can be sent to the server by triggering the screen throwing termination control, so that the server does not forward screen throwing content to the corresponding receiving end, and a communication cancellation control corresponding to each receiving end identifier can be displayed, so that a communication cancellation request can be sent to the server by triggering the communication cancellation control, and the corresponding communication number of the corresponding receiving end of the server is disconnected from the communication channel.

For the receiving end identifier of the screen which is not projected or is refused to be projected, a screen re-projection control can be displayed on the first screen projection interface so as to request the screen projection from the corresponding receiving end again, and the like.

And for the corresponding receiving end identifier of the communication number which is not answered or refused to answer, a re-communication control can be displayed on the first screen-throwing interface so as to initiate a call request and the like to the corresponding communication terminal of the corresponding communication number again.
