Background

With the development and popularization of consumer terminal devices, it has become increasingly common for a family to have multiple terminal devices at the same time, for example, one family may have terminal devices such as a Personal Computer, a tablet Computer, a smart television, a mobile phone, and a Home Theater Computer (HTPC) at the same time. Sharing media content between devices is one of the basic requirements of users, and some Alliance organizations and some companies make some protocols for media sharing and interconnection based on the existing requirements of the media sharing function, such as music share of an affiliate company, AllShare of samsung, iTunes of apple, flash Alliance, Digital Living Network Alliance (DLNA), and the like.

For example, the user terminal may send a request for updating the sharing control policy to the sharing control policy server under an instruction of the user, so as to query the sharing control policy server whether the sharing control policy corresponding to the application is updated.

In some embodiments of the present invention, the request for querying and updating the sharing control policy may carry P0 application identifiers, and certainly may also carry P0 version numbers corresponding to the P0 application identifiers one to one, where the version numbers may be corresponding version numbers of applications currently installed in the user terminal or version numbers of sharing control policies currently stored in the user terminal, so as to query, to the sharing control policy server, whether the sharing control policies corresponding to the applications identified by the P0 application identifiers are updated.

402. And after receiving the sharing control strategy updating query request sent by the user terminal, the sharing control strategy server sends a sharing control strategy updating notification message carrying P application identifications to the user terminal.

The P application ids may be a subset of the P0 application ids, the P0 application ids may also be a subset of the P application ids, and the P0 application id may also be partially or completely different from the P0 application ids.

403. The method comprises the steps that a user terminal receives a sharing control strategy updating notification message carrying P application identifications from a sharing control strategy server, and the user terminal sends a sharing control strategy issuing request carrying N application identifications to the sharing control strategy server, wherein the N application identifications are subsets of the P application identifications (for example, applications represented by the N application identifications in the P application identifications are installed in the user terminal).

404. The method comprises the steps that a sharing control strategy server receives a sharing control strategy issuing request carrying N application identifications from a user terminal, and sends a sharing control strategy issuing request response used for responding to the sharing control strategy issuing request to the user terminal, wherein the sharing control strategy issuing request response carries N sharing control strategies, the N sharing control strategies correspond to N applications represented by the N application identifications one to one, and N is a positive integer.

405. And the user terminal receives the sharing control strategy issuing request response sent by the sharing control strategy server, and can store the N sharing control strategies carried by the sharing control strategy issuing request response.

406. And the user terminal receives a sharing closing instruction.

407. And the user terminal executes the sharing closing operation of the N applications according to the N sharing control strategies.

For example, assuming that the ue is a linux architecture system, the ue can execute an "iptables-I OUTPUT-p tcp-sport 9000-j ACCEPT" command statement to open the port No. 9000 after receiving the sharing open command. Similarly, if the user terminal receives the sharing closing instruction, the user terminal may execute the "iptables-I OUTPUT-ptcp-sport 9000-j DROP" command statement to close the port9000, execute the "kill-9 process name" command statement to end the application process, and so on.

A description will be given below by taking as an example a scenario in which screen sharing is performed between user terminals (for example, between a first user terminal and a second user terminal) by invoking a screen sharing application.

Supposing that a first user terminal sends a sharing control strategy issuing request carrying N1 application identifiers to a sharing control strategy server; and receiving N1 sharing control strategies issued by the sharing control strategy server in response to the sharing control strategy issuing request, and storing N1 sharing control strategies. Wherein, the N1 sharing control policies correspond to N1 applications represented by the N1 application identifiers one to one, and the N1 is a positive integer; the N1 application identifications include a screen sharing application identification.

Optionally, the second user terminal sends a sharing control policy issuing request carrying N2 application identifiers to the sharing control policy server; and receiving N2 sharing control strategies issued by the sharing control strategy server in response to the sharing control strategy issuing request, and storing N1 sharing control strategies. The N2 shared control policies correspond to N2 applications represented by the N2 application identifiers one to one, where N2 is a positive integer; wherein, the N2 application identifications include screen sharing application identifications.

The first user terminal can call the screen sharing application to initiate the screen sharing service; a first user terminal receives a screen sharing service access request corresponding to a screen sharing service from X second user terminals through a wireless local area network, wherein the first user terminal and the X second user terminals are both positioned in the wireless local area network, and X is a positive integer; if the X second user terminals are allowed to access the screen sharing service, the first user terminal encodes the content displayed in the first area of the screen of the first user terminal into a first video stream, and sends the first video stream to the X second user terminals through the wireless local area network. In this way, the second user terminal may display the first video stream (i.e. display the content corresponding to the first video stream) in a certain area (referred to as a second area for ease of reference) of its screen after receiving the first video stream transmitted by the first user terminal, and accordingly, the second user terminal may display the first video stream in the second area of its screen after receiving the first video stream transmitted by the first user terminal.

The user terminal in the embodiments of the present invention may be an intelligent mobile terminal, a portable computer, or a personal digital processing user terminal, and of course, the user terminal in the embodiments of the present invention may have a touch display screen or other types of display screens.

It can be understood that the first user terminal (if the first user terminal is installed with the screen sharing client) initiates the screen sharing service, which means that the first user terminal allows other user terminals to share the screen with the first user terminal, and some user terminals located in the same local area network (for example, user terminals installed with the screen sharing client) may monitor that the first user terminal starts the screen sharing service, and may access the screen sharing service started by the first user terminal. The user terminal initiating the screen sharing service may be referred to as a screen sharing service initiator, and the user terminal accessing the screen sharing service may be referred to as a screen sharing service access party.

In some embodiments of the present invention, the initiating, by the first user terminal, the screen sharing service may include: the first user terminal broadcasts a screen sharing service starting message corresponding to the screen sharing service in the wireless local area network, wherein the screen sharing service access request corresponding to the screen sharing service is sent by a second user terminal after the screen sharing service starting message is received.

In addition, in some other embodiments of the present invention, the initiating, by the first user terminal, the screen sharing service may include: the method comprises the steps that a first user terminal receives screen sharing service starting inquiry requests from X second user terminals, screen sharing service starting messages corresponding to the screen sharing services are broadcasted in the wireless local area network, or screen sharing service starting messages used for responding to the screen sharing service starting inquiry requests are sent to the X second user terminals, wherein the screen sharing service access requests corresponding to the screen sharing services are sent by the second user terminals after the screen sharing service starting messages are received.

In some embodiments of the present invention, the first ue may determine whether to allow the X second ues to access the screen sharing service according to a user instruction or a remaining amount of processing resources or a signal quality of a wireless local area network.

It can be understood that, after receiving the screen sharing service access request from the second user terminal, the first user terminal may send a screen sharing service denial access message (or no message is replied) to the second user terminal if the second user terminal is not allowed to access the screen sharing service, and may send a screen sharing service permission access message to the second user terminal if the second user terminal is allowed to access the screen sharing service.

The first user terminal may select a certain area (referred to as a first area for convenience of reference) in the screen as the screen sharing area. The first region selected by the first user terminal as the screen share may occupy a part or all of the area of the screen of the first user terminal, and the first region occupies a part of the area of the screen of the first user terminal as an example in fig. 4-b. The first user terminal may display picture, video, document, desktop, etc. content in the first area.

The following illustrates a manner in which the first user terminal selects the screen sharing area, as shown in fig. 4-b. After a user triggers the operation of selecting the sharing area, the first user terminal covers a semi-transparent image layer on the current screen, the user can slide a finger on the semi-transparent image for a long time, in the finger sliding process, the initial touch point of the finger is used as the vertex, the current touch point in the finger sliding process is used as the diagonal vertex to generate a rectangular frame, and the rectangular frame is continuously redrawn and changed along with the sliding of the finger. When the finger leaves the screen and stops sliding, the first user terminal records the position and size parameters of the current selected area, and simultaneously can pop up an option menu bar, the option menu bar is displayed at the bottom of the screen, and the user selects a desired operation in the option menu to complete the setting of the screen sharing area. For example, there are three types of options menu, i.e., "cancel", "reselect", and "determine". The selection of 'cancel' is to give up the setting of this time, the first user terminal can cancel the display of the option menu, cancel the display of the rectangular frame of the selected area, cancel the display of the semitransparent layer, and exit the setting mode; selecting 'reselect' indicates that the sharing area is to be reset, the first user terminal disappears the rectangular frame and the option menu bar of the selected area, and the user can execute the setting step again; and after the 'determination' is selected, the first user terminal cancels the option menu display, cancels the rectangular frame display of the selected area and cancels the semi-transparent layer display.

In some embodiments of the present invention, the first user terminal serves as a wifi hotspot, and the X second user terminals access the wireless local area network through the wifi hotspot (see fig. 4-c). Or, one of the X second user terminals serves as a wifi hotspot, and the first user terminal and the remaining second user terminals of the X second user terminals except the one second user terminal access the wireless local area network through the wifi hotspot (see fig. 4-d). Or, the first user terminal serves as a group owner, and the X second user terminals serve as group clients, and access the wireless local area network in a wifi direct connection manner (see fig. 4-e). Or one of the X second user terminals serves as a group owner, and the first user terminal and the remaining second user terminals of the X second user terminals except the one second user terminal serve as group clients, and access the wireless local area network in a wifi direct connection manner (see fig. 4-f). Or the first user terminal and the X second user terminals access the wireless local area network through a third-party wifi hotspot (see fig. 4-g). Of course, the first ue and the X second ues may access the same wlan through other methods.

In some embodiments of the present invention, the first user terminal may send the first video stream to the X second user terminals through the wireless local area network based on a multicast or unicast manner. For example, the first user terminal may comprise a video stream buffer queue and a block buffer queue; for the unicast mode, the first user terminal can put the video frames of the first video stream into the video stream buffer queue in turn according to the first-in first-out principle, wherein, if the first video frame stored in the X1 th queue unit in the video stream buffer queue is to be replaced by the second video frame in the first video stream, the first video frame still cannot be successfully transmitted to K4 second user terminals among the X second user terminals (i.e.: the K4 second user terminals did not successfully acquire the first video frame), the first video frame is written into a queue unit corresponding to K4 second user terminals in the blocking buffer queue (wherein at least one queue unit corresponds to each of the X second user terminals in the blocking buffer queue), and the first video frame stored in the X1 th queue unit is replaced by the second video frame. Wherein the sending the first video stream to the X second user terminals through the wireless lan may include: and aiming at each second user terminal in the X second user terminals, sending the video frames of the first video stream read from the video stream buffer queue and/or the blocking buffer queue to each second user terminal. It can be seen that, the video stream buffer queue and the blocking buffer queue are cooperatively used in the user terminal initiating the screen sharing service, which is beneficial to saving memory overhead in a scenario where there are a plurality of user terminals accessing the screen sharing service, because the first user terminal does not need to store unsuccessfully distributed video frames in the video stream buffer queue for a long time, the dequeuing speed of the video stream buffer queue can be synchronized with the speed of the encoded first video stream, and at least one queue unit is corresponding to each second user terminal in the X second user terminals in the blocking buffer queue, which is beneficial to realizing that each video stream does not affect each other, and is further beneficial to achieving the technical effect of saving memory overhead and time overhead without affecting each video stream.

In some embodiments of the present invention, if the first user terminal receives a first user operation event from the second user terminal through the wireless local area network, the first user operation event is executed, where the first user operation event is a user operation event for a second area in a screen of the second user terminal, and the second area displays a first video stream received by the second user terminal. The first user terminal can add the first user operation event into the system operation event linked list, and execute the first user operation event according to the execution sequence of each event in the system operation event linked list. The first user operation event may be a plurality of user operation events for a second area in a screen of the second user terminal, and assuming that the second area displays an animation, the first user operation event may be, for example, a user operation event for adjusting the progress, brightness, contrast, and/or size of the animation displayed in the second area. Assuming that the second area displays a desktop including a plurality of application icons, the first user operation event may be, for example, a user operation event for starting an application corresponding to a certain application icon in the desktop displayed in the second area, and so on. If necessary, the second user terminal may convert the monitored user operation event for the second area in the screen of the second user terminal into a first user operation event in a specified format (for example, the first user terminal specifies the format of the user operation event), and send the first user operation event to the first user terminal through the wireless local area network, so that the first user terminal can execute the first user operation event. Of course, if the system types of the first user terminal and the second user terminal are the same, and the first user terminal can identify the user operation event monitored by the second user terminal, the second user terminal can send the monitored user operation event to the first user terminal without performing format conversion.

In some embodiments of the present invention, the screen sharing may further support a doodle function, for example, the first user terminal may further cover a transparent layer on the first area; the first user operation event is a graffiti drawing event, wherein if the first user terminal receives the first user operation event from the second user terminal through the wireless local area network, the first user operation event is executed, and the method comprises the following steps: if the first user terminal receives the scrawling drawing event from the second user terminal through the wireless local area network, the scrawling to be drawn by the scrawling drawing event can be displayed on the transparent layer, and the drawn scrawling can be shared with other screen sharing service access parties. For example, as shown in fig. 4-h, the screen sharing service initiator S shares the content of the screen sharing area with the screen sharing service access party Pad and PhoXe, first, Pad makes a doodle mark on the sharing area, and at this time, all three devices can see the doodle mark made by Pad; and then, the phoXe makes some scrawling marks on the shared area, the three devices can see the scrawling marks made by the PhoXe, and the rest scenes can be analogized.

In some embodiments of the present invention, the first user terminal may further collect a sound signal played by the first user terminal, encode the collected sound signal into a first audio stream, and interleave the first audio stream into the first video stream, or the first user terminal may decode an audio file to obtain the first audio stream, interleave the obtained first audio stream into the first video stream,

wherein the sending the first video stream to the X second user terminals through the wireless lan may include: and distributing the first video stream interwoven with the first audio stream to the X second user terminals through the wireless local area network. Thus, the first user terminal can issue a voice command or play background music and the like to the second user terminal.

In some embodiments of the present invention, the first user terminal interleaves the first audio stream and the first video stream into a video stream in a hypertext transfer protocol Live Streaming (HLS) format, and the first user terminal may also interleave the first audio stream and the first video stream into a video stream in a non-HLS format, for example, the first user terminal may interleave the first audio stream and the first video stream into a video stream in a format specified by the second user terminal. And part or all of the X second user terminals can access the video stream in the HLS format in a browser mode, and part or all of the X second user terminals can access the video stream in the non-HLS format in a special client mode.

In some embodiments of the present invention, the bitrate of the first video stream may be constant. Or, the bitrate of the first video stream may correspond to the size of X, for example, when the number of the user terminals accessing the screen sharing service changes, the bitrate of the video stream may be dynamically adjusted by the first user terminal, for example, when the first user terminal detects that the number of the user terminals accessing the screen sharing service changes, the bitrate of the video stream may be adjusted according to the changed number of the user terminals accessing the screen sharing service, and assuming that the bitrate of the video stream when only 1 user terminal accessing the screen sharing service is set is a, and the number of the user terminals currently accessing the screen sharing service is X, then the bitrate of the current video stream should be a/X. That is, the larger the number of user terminals accessing the screen sharing service is, the lower the bitrate of the video stream is. Or, the bitrate of the first video stream may correspond to the type of the display content of the first area, for example, if the type of the content currently displayed in the first area by the first user terminal is a high-dynamic picture (such as a video, an interface animation, and the like), the first user terminal may increase the frame rate of the first video stream, and decrease the frame size of the first video stream, so as to increase the fluency of the first video stream; if the type of the content currently displayed in the first area by the first user terminal is a non-high dynamic picture, the first user terminal can reduce the frame rate of the video stream and increase the frame size of the video stream so as to increase the definition of the first video stream.

It can be understood that the first user terminal may decide whether to start encoding of the first video stream according to whether the user terminal of the screen sharing service is accessed. For example, if the user terminal does not have the accessed screen sharing service, the encoding of the first video stream is not started; if at least one user terminal of the accessed screen sharing service exists, starting the coding of the first video stream; if all the user terminals of the accessed screen sharing service are disconnected, the first user terminal may stop encoding of the first video stream. Of course, the first user terminal may also perform encoding of the first video stream all the time during the screen sharing service initiation.

In some embodiments of the invention, the first user terminal may also turn on a remote clip service; if M second user terminals among the X second user terminals access the remote clipboard service through the wireless local area network, when the first user terminal monitors that an updated clipboard object exists on a system clipboard of the first user terminal, the clipboard object is sent to the M second user terminals through the wireless local area network, so that the M second user terminals update the received clipboard object on the system clipboard.

In some embodiments of the invention, voice tagging may also be implemented while the screen is shared. The first user terminal may further transmit a voice tag service on indication to K1 second user terminals among the X second user terminals, for example, when the first user terminal displays a document in a first region of its screen; if receiving the voice mark recorded by some or all of the K1 second user terminals after receiving the voice mark service start instruction, storing the voice mark and recording the association relationship between the voice mark and a first document, where the first document is a document displayed by the first user terminal in a first area of a screen during recording the voice mark. Further, the first user terminal may play a voice mark having an association relation therewith when the first document is opened again. It is understood that K1 is less than or equal to X.

For another example, when the first user terminal displays a picture in a first area of the screen thereof, the first user terminal sends a voice tag service start instruction to K2 second user terminals among the X second user terminals; if receiving the voice tag recorded by some or all of the K2 second user terminals after receiving the voice tag service start instruction, storing the voice tag and recording the association relationship between the voice tag and a first picture, where the first picture is a picture displayed by the first user terminal in a first area of a screen during recording the voice tag. Further, the first user terminal may play a voice tag having an association relation with the first picture when the first picture is opened again.

It is understood that K2 is less than or equal to X.

For another example, when the first user terminal displays a video in a first area of its screen, the first user terminal sends a voice tag service on instruction to K3 second user terminals among the X second user terminals; if receiving the voice mark recorded by some or all of the K3 second user terminals after receiving the voice mark service start instruction, storing the voice mark and recording the association relationship between the voice mark and a first video, where the first video is a video displayed by the first user terminal in a first area of a screen during recording the voice mark. Other scenarios may be voice tagged in a similar manner. Further, the first user terminal may play a voice tag having an association with the first video when the first video is turned on again. It is understood that K3 is less than or equal to X.

It can be seen that, in this embodiment, after the first user terminal starts the screen sharing service allowing the multiple user terminals to access; if X second user terminals are accessed to the screen sharing service started by the first user terminal through the wireless local area network, the first user terminal codes the content displayed in the first area of the screen of the first user terminal into a first video stream, and sends the first video stream to the X second user terminals through the wireless local area network. In addition, the screen sharing technology in the embodiment of the invention can better support scenes with high requirements on fluency and real-time performance by means of higher transmission rate of the wireless local area network, and the first user terminal can realize the access control of the screen sharing services of a plurality of X second user terminals by means of the wireless local area network, and is also favorable for enhancing the flexibility of screen sharing participation and further favorable for expanding the number of screen sharing participants.

Furthermore, different coding means can be adopted according to different types of current screen display contents, so that the problem of balance between fluency requirements in scenes needing high fluency, such as videos or interface animations, and the like and definition requirements in image display scenes can be solved, and the dynamic response effect of coded video streams on scene requirements during switching of screen display scenes can be achieved.

Furthermore, the video stream buffer queue and the blocking buffer queue are cooperatively used in the user terminal initiating the screen sharing service, which is beneficial to saving memory overhead in a scene where a plurality of user terminals accessing the screen sharing service exist, and realizing that each path of video stream does not influence each other, thereby being beneficial to achieving the technical effect of saving the memory overhead and the time overhead under the condition that each path of video stream is not influenced.

In the process of screen sharing between the first user terminal and the second user terminal, the first user terminal receives a sharing closing instruction. The first user terminal can execute sharing closing operation of the N applications (including the screen sharing application) according to the N sharing control strategies.

In some embodiments of the present invention, the first user terminal may receive a sharing shutdown instruction generated by a user by clicking a sharing shutdown icon on a desktop, or the first user terminal may also receive a sharing shutdown instruction generated by the user by triggering in another manner, or the first user terminal may also receive a sharing shutdown instruction sent by another object.

In some embodiments of the invention, a first sharing control policy corresponding to the screen sharing application in the N sharing control policies may include: the method comprises the steps of identifying an application identifier of a screen sharing application, a process name of the screen sharing application, a version number of the screen sharing application and a sharing port set of the screen sharing application. Of course, the first sharing control policy may further include other information such as a manufacturer of the screen sharing application, an overview of the screen sharing application, and the like. The information contained in the sharing control strategy corresponding to other applications can be analogized.

In some embodiments of the present invention, the executing, by the first user terminal, the sharing shutdown operation of the N applications (including the screen sharing application) according to the N sharing control policies may include: extracting a first port set which is required to be used by the N application shares and contained in the N sharing control strategies; closing the third port set and ending the corresponding process of the application needing to use any one port in the second port set in the third application set; the third application set is a difference between an intersection of the first application set and the second application set, the second application set is an application set recorded in a preset sharing control white list, the third port set is a difference between an intersection of the first port set and the second port set, the second port set is a port set required to be used by the second application set, and the first application set is composed of the N applications.

For example, the first user terminal extracts a first port set that the N applications included in the N sharing control policies share and need to use, the N applications form a first application set, the first user terminal extracts a second application set and a second port set recorded in the sharing control white list, the first user terminal removes elements included in the second application set from the first application set to obtain a third application set, the first user terminal removes elements included in the second port set from the first port set to obtain a third port set, the elements in the third application set are further determined, if at least 1 of the sharing ports used by the applications in the third application set exists in the second port set, the applications are added to an application set a4 that needs to be terminated to be finally, the user terminal closes the third port set, and ends a corresponding process of the application set a 4.

In another embodiment of the present invention, the executing the sharing shutdown operation of the N applications according to the N sharing control policies includes: extracting a first port set which is required to be used by the N applications (including screen sharing applications) contained in the N sharing control strategies; closing the third port set and ending the process of the application which needs to use any one port in the second port set in the N applications; and the third port set is the difference between the intersection of the first port set and the second port set, and the second port set is a port set recorded in a preset sharing control white list.

In still other embodiments of the present invention, the executing the sharing shutdown operation of the N applications according to the N sharing control policies includes: extracting a first port set which needs to be used by the N applications (including screen sharing applications) contained in the N sharing control strategies in a sharing mode; the extracted first port set is closed.

It is understood that the screen sharing service between the first user terminal and the second user terminal is interrupted after the first port set is closed. In particular, if the screen sharing application is recorded in the sharing control white list, the port used by the screen sharing application for sharing will not be closed, and the screen sharing service between the first user terminal and the second user terminal can continue.

It is understood that the screen sharing service is taken as an example in the above example, and the sharing control of other applications can be performed in the same way.
