Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

Referring to fig. 1, an embodiment of the present invention provides a method for displaying a shared screen, where the method is applied to a first device, where the first device may be a terminal device, and the method may include the following steps:

step 101: at least one second device that needs to display the same shared screen as the first device is determined.

The shared picture is a picture with the same display content on a plurality of devices. For example, in a game in which multiple persons can participate, a plurality of devices participating in the game may display some of the same pictures, or, in a video conference in which multiple persons participate, a plurality of devices participating in the video conference may display some of the same pictures. Thus, the shared screen may be an in-game screen or a screen of a video conference.

For example, a game has 40 frames or 60 frames per second, each frame having a frame, and for a portion of the game, a portion of the 60 frames are shareable. As shown in fig. 2, the device a and the device B participate in the same game, wherein, of the video frames included in the duration of one second, the display content of the first video frame 201 on the device a and the device B is the same, and then the first video frame 201 belongs to the shared screen.

In addition, the server may issue identification information of each device that needs to display the same shared screen to the first device and the second device. For example, in a game in which multiple devices participate, the server may issue to each device identification information for the device participating in the game; or in a video conference in which multiple devices participate, the server may also issue identification information of the devices participating in the video conference to each device.

Step 102: determining a master device and a slave device of the first device and the at least one second device.

Wherein, one or more master devices may exist in the first device and the at least one second device, and one or more slave devices may also exist.

Step 103: and rendering the shared picture and sending the shared picture to the at least one second device or receiving the shared picture sent by one device except the first device in the main device under the condition that the first device is the main device.

Step 104: and receiving the shared picture sent by one of the master devices when the first device is a slave device.

As can be seen from

steps

103 and 104, in the embodiment of the present application, one of the master devices is used to render the shared screen and then sends the shared screen to the other devices (i.e., the devices other than the device that renders the shared screen in the first device and the second device); the slave device does not need to render the shared picture, and only needs to receive and display the shared picture rendered by the master device.

Therefore, in the embodiment of the present application, it is a device that renders the shared screen, and other devices all receive the shared screen sent by the device, and then, in the embodiment of the present application, there is no rendering speed difference due to the performance difference of the devices. Therefore, compared with the prior art, the embodiment of the application can shorten the speed gap of loading the same picture by each device.

Step 105: and displaying the sharing picture.

As can be seen from the above description, in the embodiment of the present application, at least one second device that needs to display the same shared screen as the first device can be determined, and a master device and a slave device of the devices can be determined, so that when the first device is the master device, the first device renders the shared screen and sends the shared screen to the second device, or the first device receives the shared screen sent by another master device; and receiving the shared picture transmitted by one of the master devices when the first device is the slave device.

In the prior art, many people collaborate with a hand game and are popular with the vast population, and the intelligent terminals used by users have various brands, models and the like. Therefore, the fluency of the operation can be different for the same hand trip. The number of frames transmitted per second, the refresh rate (i.e., FPS), are important parameters for measuring the smoothness of the game. Generally, to some extent, the higher the FPS, the faster the game will react. Generally, the rendering of each frame of game screen needs to consume a CPU, so for a game with cooperation of multiple users, the CPU performance of the intelligent electronic device used by some users is strong, and the CPU performance of the intelligent electronic device used by some users is poor, so that the speeds at which the intelligent terminal with a large performance gap loads the game screen are different, and further, the operation efficiency of the users in the game process is different, thereby affecting the fluency of the whole game.

And if in a game in which a plurality of persons participate, the display method of the shared picture provided by the embodiment of the application is adopted, the main device and the slave device in the plurality of devices participating in the game can be determined, so that one main device renders the shared picture in the game picture, and then sends the shared picture to other main devices and slave devices, thereby shortening the speed difference of loading the same picture by each device, further improving the operation efficiency of a user in the game process, and improving the smoothness of the whole game.

In addition, in a video conference in which a plurality of intelligent terminals participate, the display pictures of the intelligent terminals are often the same, but the video picture rendering speeds of the intelligent terminals are different due to different performances of the intelligent terminals, so that the loading speeds of the video pictures of the intelligent terminals have large deviation.

And if in a video conference in which multiple persons participate, by adopting the display method of the shared picture provided by the embodiment of the application, the master device and the slave device in the multiple devices participating in the video conference can be determined, so that one master device renders the shared picture in the video conference, and then the shared picture is sent to other master devices and slave devices, thereby shortening the speed difference of loading the same picture by each device, and further improving the fluency of the video conference.

In addition, the process of "rendering the shared screen when the first device is the master device" in the step 103 may be one of the following first method and second method.

The first method is as follows: a single master renders a shared screen.

Optionally, there is one master device in the first device and the at least one second device, and the shared picture includes at least one frame of picture of the target object;

in a case where the first device is a master device, a process of rendering the shared screen includes:

when the value of i is each integer from 1 to N, the following processes are respectively executed:

rendering the ith frame picture of the target object under the condition that the first equipment is main equipment and the ith frame picture of the target object belongs to the shared picture;

wherein N is the total number of frame pictures of the target object, and N is greater than or equal to 1. Optionally, the target object is a game or a video conference.

In addition, when the first device is a slave device and an ith frame picture of the target object belongs to the shared picture, the first device receives the shared picture transmitted by the master device.

For example, two frames of shared pictures exist in three frames of pictures of the target object, namely a first frame and a third frame, if one main device exists and the first device is the main device, the first device firstly judges whether the first frame of picture to be displayed is the shared picture, if so, the first frame of picture is rendered, the first frame of picture is displayed and sent to the second device; then, the first equipment judges whether a second frame of picture to be displayed is a shared picture, if not, the second frame of picture is rendered, and the second frame of picture is displayed; and thirdly, the first equipment judges whether the third frame of picture to be displayed is a shared picture, if so, the third frame of picture is rendered, displayed and sent to the second equipment.

Under the condition that the first equipment is slave main equipment, the first equipment firstly judges whether a first frame picture to be displayed is a shared picture, and if so, the first frame picture is displayed after the first frame picture sent by the main equipment is received; then, the first equipment judges whether a second frame of picture to be displayed is a shared picture, if not, the second frame of picture is rendered, and the second frame of picture is displayed; and thirdly, the first equipment judges whether the third frame of picture to be displayed is a shared picture, and if so, the third frame of picture is displayed after the third frame of picture sent by the main equipment is received.

Therefore, in the embodiment of the present application, in a case that there is one master device and the first device is the master device, the first device needs to determine whether the frame to be rendered belongs to the shared frame before rendering each frame of the target object, and if so, the first device needs to send the rendered frame to the second device after rendering the frame; if there is one master device and the first device is a slave device, the first device also needs to determine whether each frame of picture to be displayed belongs to a shared picture, and if so, waits to receive the shared picture sent by the master device.

It can be seen that, when one master device exists in the first device and the at least one second device, the master device always renders a shared screen among screens of the target objects, and then sends the shared screen to the other devices.

Optionally, the method further includes:

and rendering the ith frame picture of the target object under the condition that the ith frame picture of the target object does not belong to the shared picture.

That is, when there is one master device in the first device and the at least one second device, the first device needs to render itself for a screen that does not belong to the shared screen, regardless of whether the first device is the master device or not.

As can be seen from the above, when one master device exists in the first device and the at least one second device, the master device renders the shared screen among the screens of the target objects, and the other devices do not need to render, and receive and display the shared screen rendered by the master device. And rendering is required for the non-shared picture in the picture of the target object, no matter the master device or the slave device. Therefore, according to the embodiment of the application, the process of rendering the shared picture is arranged on one side of the master device, and the slave device does not need to render the shared picture, so that the processing resources of the multi-frame picture of the slave device are saved, and the response speed of the slave device can be increased.

The second method comprises the following steps: the multiple master devices render the shared picture in turn.

Optionally, there are multiple primary devices in the first device and the at least one second device, and the shared picture includes a multi-frame picture of a target object;

before rendering the shared screen, the method further comprises:

acquiring the number of the first device in a target sequence, wherein the target sequence is acquired after the plurality of main devices are sequenced according to a preset rule, and the difference between the numbers of every two adjacent main devices in the target sequence is a preset value;

rendering the ith frame picture of the target object under the condition that the first equipment is main equipment, the ith frame picture of the target object belongs to the shared picture, and the current value of the preset shared number is the same as the number of the first equipment;

increasing the value of the shared number by the preset value under the condition that the current value of the shared number is smaller than the maximum value of the numbers in the target sequence, wherein the initial value of the shared number is the minimum value of the numbers in the target sequence;

setting the value of the shared number as the minimum value of the numbers in the target sequence under the condition that the current value of the shared number is equal to the maximum value of the numbers in the target sequence;

wherein N is the total number of frame pictures of the target object, and N is greater than 1. Optionally, the target object is a game or a video conference.

Therefore, under the condition that a plurality of main devices exist, a sharing number needs to be preset, the main devices are sequenced according to a preset rule to obtain target sequencing, and then numbers are distributed to the main devices according to the positions of the main devices in the target sequencing. Therefore, when the first device is one of the main devices, before the ith frame picture needs to be displayed, the first device further judges whether the number of the first device is the same as the current value of the shared number or not under the condition that the ith frame picture belongs to the shared picture, if so, the first device renders the ith frame picture, increases the shared picture by a preset value when the current value of the shared number is not the maximum value of the code, and resets the shared number to the minimum value of the code when the current value of the shared number is the maximum value of the code.

It can be seen that the current value of the shared number determines which master is currently rendering. Namely, in the embodiment of the application, after one frame of picture is rendered each time, the value of the shared number is increased by the preset value until the value of the shared number reaches the maximum value of the code, and the value is set as the minimum value of the code again, so that the shared picture is rendered by a plurality of main devices in turn, the pressure for rendering the shared picture is dispersed to the plurality of main devices, and the response speed of each device is further accelerated.

It should be further noted that, for the number of the master device, all the master devices may be sorted according to a preset rule by each master device itself, and the master devices are numbered according to the same numbering rule; or the server may sort and number all the master devices according to a preset rule, and then send the corresponding codes to each master device.

Optionally, in a case that the first device is a master device, a process of receiving the shared picture sent by one of the devices except the first device in the master device includes:

receiving an ith frame of the target object sent by a target main device under the condition that the first device is a main device, the ith frame of the target object belongs to the shared frame, and the current value of the shared number is different from the number of the first device, wherein the number of the target main device is the main device of the current value of the shared number;

and setting the value of the shared number as the minimum value of the numbers in the target sequence under the condition that the current value of the shared number is equal to the maximum value of the numbers in the target sequence.

Therefore, in a manner that a plurality of masters render a shared picture in turn, if a first device is a master and an ith frame picture belongs to the shared picture but a current value of a shared number is different from a code of the first device, the first device waits for receiving the ith frame picture sent by the master with the same number as the current value of the shared number, displays the ith frame picture, increases the shared picture by a preset value when the current value of the shared number is not the maximum value of the code, and resets the shared number to the minimum value of the code when the current value of the shared number is the maximum value of the code.

As can be seen from the above, in the embodiment of the present application, after each master device renders one frame of shared image, or receives one frame of shared image sent by another master device, the value of the shared number needs to be modified, so that the next frame of shared image can be replaced by another device for rendering.

Optionally, in a case that the first device is a slave device, a process of receiving the shared picture sent by one of the master devices includes:

and under the condition that the first equipment is slave equipment and the ith frame picture of the target object belongs to the shared picture, receiving the ith frame picture of the target object sent by target main equipment, wherein the number of the target main equipment is the main equipment with the current value of the shared number.

Therefore, in the mode that the plurality of master devices render the shared picture in turn, each slave device does not need to render the shared picture, and receives and displays the shared picture rendered by the master device. Also, in this way, the slave device does not need to modify the value of the shared number.

Optionally, the method further includes:

That is, when there are a plurality of masters in the first device and the at least one second device, the masters and the slaves need to render screens that do not belong to the shared screen by themselves.

In summary of the above two embodiments, for example, if the device A, B, C, D participates in the same game, the device A, B is the master device, the device a is numbered 1, the device B is numbered 2, and the device C, D is the slave device, the flow of displaying the screen of the game on the device A, B, C, D can be as follows:

for a first frame picture:

for the device a, it is determined that the first frame of picture of the game belongs to the shared picture, and the current value of the shared number is 1, the device a renders the first frame of picture, adds 1 to the value of the shared number, and then sends the first frame of picture to the device B, C, D.

For the B device, judging that the first frame of picture of the game belongs to the shared picture, if the current value of the shared number is 1, waiting for receiving the first frame of picture, and adding 1 to the value of the shared number;

for the C, D device, judging that the first frame of picture of the game belongs to the shared picture, and waiting for receiving the first frame of picture;

for the second frame picture:

the device A, B, C, D respectively judges that the first frame of picture of the game does not belong to the shared picture, and respectively renders the second frame of picture;

for the third frame picture:

and for the device A, judging that the third frame of picture of the game belongs to the shared picture, if the current value of the shared number is 2, waiting for receiving the third frame of picture, and resetting the value of the shared number to be 1.

For the device B, if it is determined that the third frame of picture of the game belongs to the shared picture and the current value of the shared number is 2, rendering the third frame of picture, resetting the value of the shared number to 1, and then sending the third frame of picture to the device A, C, D;

for the C, D device, judging that the third frame of picture of the game belongs to the shared picture, and waiting for receiving the third frame of picture;

for other pictures after the third frame, refer to the processing flow of the first to third frames, which is not described herein again.

Therefore, the shared picture is rendered by the plurality of main devices in turn, so that the pressure for rendering the shared picture can be dispersed to the plurality of main devices, and the response speed of each device can be further increased.

Optionally, before rendering the ith frame of the target object, the method further includes:

requesting source data of an ith frame of the target object from a server;

receiving source data of an ith frame of picture of the target object sent by the server;

under the condition that a preset sharing mark exists in source data of an ith frame of picture of the target object, determining that the ith frame of picture of the target object belongs to the sharing picture;

the rendering of the ith frame of the target object comprises:

and rendering an ith frame picture of the target object according to the source data of the ith frame of the target object.

The preset sharing flag is used for indicating that the picture belongs to a shared picture, that is, if the preset sharing flag exists in the source data of the ith frame picture, the picture of the ith frame belongs to the shared picture.

Therefore, in the embodiment of the present application, a preset sharing flag may be added in advance to a picture belonging to a shared picture in a picture of a target object on the server side, so as to distinguish the shared picture from a non-shared picture. Therefore, after the device receives the source data sent by the server, whether the picture to which the source data belongs is a shared picture can be judged according to whether the preset shared mark exists in the source data.

In addition, the first device and the second device may both request the server for the source data of the ith frame of the target object, and then the server returns the source data of the ith frame to the first device and the second device, respectively. In the first device and the second device, the device which needs to render the ith frame image is only required to render according to the source data of the ith frame image, and the device which does not need to render the ith frame image is only required to discard the source data of the ith frame image.

Optionally, the determining a master device and a slave device in the first device and the at least one second device includes:

receiving a master device list sent by a server, wherein the master device list comprises identification information of at least one master device;

determining a device existing in the master device list among the first device and the at least one second device as the master device;

and determining other devices except the master device in the first device and the at least one second device as the slave devices.

Therefore, the server can issue the master device list to each device, so that each device can determine which devices belong to the master device and which devices belong to the slave device according to the master device list.

Each device (i.e., the first device and the second device) may report its device parameter to the server, and then the server selects one or more devices with better performance as the master device according to the device parameter, so as to generate a master device list and send the master device list to each device. Therefore, the shared picture can be rendered by using the equipment with better performance subsequently, the loading speed of the shared picture can be further increased, and the response speed of each equipment is increased.

In addition, it should be noted that, if the number of the master device is determined by the server sorting and numbering all master devices according to a preset rule, the number of each master device may be carried in the master device list and issued to each master device.

Optionally, before receiving the master device list sent by the server, the method further includes:

receiving a first input in the first device;

and responding to the first input, and sending first indication information to the server, wherein the first indication information is used for indicating that the first equipment is set as a main equipment.

Wherein the first input is an input of a user in a first device. For example, a control switch may be preset, and when a user operates the control switch displayed on the first device to turn on, the first device is set as the master device, so as to trigger the first device to report that it is set as the master device to the server.

In addition, after the server receives the first indication information which is set as the master device and reported by each device, the server may generate a master device list according to the first indication information.

In addition, a plurality of users can negotiate with each other, and one or more devices with better performance are selected as the main devices, so that the corresponding devices are triggered to report the first indication information to the server, and the server generates a main device list and issues the main device list to each device. Therefore, the shared picture can be rendered by using the equipment with better performance subsequently, the loading speed of the shared picture can be further increased, and the response speed of each equipment is increased.

Optionally, the sending the shared screen to the at least one second device includes:

under the condition that the first equipment and the at least one second equipment are connected with the same local area network, sending the shared picture to the at least one second equipment through the local area network;

the receiving the shared picture sent by one of the devices except the first device in the master device includes:

under the condition that the first device and the at least one second device are connected with the same local area network, receiving the shared picture sent by one device except the first device in the main device through the local area network;

the receiving the shared picture sent by one of the master devices includes:

and receiving the shared picture sent by one of the main devices through the local area network under the condition that the first device and the at least one second device are connected to the same local area network.

As a result, when the first device and the second device are connected to the same lan, the shared screen can be transmitted between these devices via the lan. Compared with cross-network forwarding, the speed of forwarding the shared picture in the same local area network is higher, and therefore, in the embodiment of the application, the loading speed of the shared picture can be further increased by transmitting the shared picture between the devices through the local area network.

Optionally, the process of determining that the first device and the at least one second device are connected to the same local area network includes:

sending a list request to a router of a local area network to which the first device is connected;

receiving a device connection list of the router sent by the router;

sending the device connection list to a server, so that the server determines whether the first device and the at least one second device are connected to the same local area network according to the device connection list sent by the first device and the device connection list sent by the at least one second device;

and receiving second indication information returned by the server under the condition that the device connection list sent by the first device is the same as the device connection list sent by the at least one second device, wherein the second indication information is used for indicating that the first device and the at least one second device are connected to the same local area network.

Therefore, in the embodiment of the present application, the first device and the second device may respectively send a list request to the routers of the local area networks connected to the first device and the second device to obtain the device connection lists of the routers of the local area networks connected to the first device and the second device, and report the device connection lists to the server, so that the server determines whether the device connection lists received by the server are the same, if the device connection lists are the same, it indicates that the first device and the second device are connected to the same local area network, and if the device connection lists are not the same, it indicates that the first device and the second device are connected to different local area networks.

It should be noted that, for example, after the first device and the second device receive the device connection list returned by the router, the respective received device connection lists may be forwarded to other devices, and then the respective devices determine whether the finally received device connection lists are the same, so as to obtain a conclusion that whether the first device and the second device are connected to the same lan.

Referring to fig. 3, an embodiment of the present invention provides a method for displaying a shared screen, where the method is applied to a server, and the method may include the following steps:

step 301: and receiving a data request of an ith frame picture of the target object sent by at least one device.

Step 302: and under the condition that the ith frame picture of the target object belongs to a shared picture, sending source data of the ith frame picture of the target object to the at least one device, so that a third device renders the ith frame picture of the target object according to the source data of the ith frame picture of the target object, and sending the ith frame picture of the target object to other devices by the third device.

Wherein the third device is one of the master devices in the at least one device, and the other devices are devices other than the third device in the at least one device; the shared picture is a picture which needs to be displayed on each device of the at least one device, the source data of the ith frame picture of the target object comprises a preset shared mark, and i is a positive integer.

In an embodiment of the present application, the preset sharing flag is used to indicate that the picture belongs to a shared picture, that is, if the preset sharing flag exists in the source data of the ith frame picture, the picture indicates that the ith frame picture belongs to the shared picture. Therefore, in the embodiment of the present application, a preset sharing flag may be added in advance to a picture belonging to a shared picture in a picture of a target object on the server side, so as to distinguish the shared picture from a non-shared picture. Therefore, after the device receives the source data sent by the server, whether the picture to which the source data belongs is a shared picture can be judged according to whether the preset shared mark exists in the source data.

In addition, each device may request the server for source data of an ith frame of the target object, and then the server returns the source data of the ith frame to the devices, respectively. Among the devices, the device which needs to render the ith frame image renders according to the source data of the ith frame image, the device which does not need to render the ith frame image discards the source data of the ith frame image, and the device which renders the ith frame image sends the rendered ith frame image to the device which does not render the ith frame image.

As can be seen from the above, in the embodiment of the present application, after receiving a data request of an ith frame of a target object sent by a device, when the ith frame belongs to a shared frame, a server may add a preset shared flag to source data of the ith frame, so as to send the source data of the ith frame to the device that sent the data request, and then one of the devices renders the ith frame, and then sends the ith frame to the other host device. In the embodiment of the present application, one device renders a shared picture, and other devices receive the shared picture sent by the device, so that in the embodiment of the present application, there is no rendering speed difference caused by a performance difference between the devices. Therefore, compared with the prior art, the embodiment of the application can shorten the speed gap of loading the same picture by each device.

Optionally, before the receiving a data request of an ith frame of a picture of a target object sent by at least one device, the method further includes:

determining a master device of the at least one device;

when a plurality of main devices exist in the at least one device, sequencing the plurality of main devices according to a preset rule to obtain a target sequence;

according to the positions of the master devices in the target sequence, numbers are distributed to the master devices, wherein the difference between the numbers of every two adjacent master devices in the target sequence is a preset value;

and sending the number of the master device in the target sequence to each master device.

Therefore, under the condition that a plurality of main devices exist, the server can sequence the main devices according to a preset rule to obtain target sequence, numbers are distributed to the devices according to the positions of the devices in the target sequence, and then the corresponding numbers are sent to the devices, so that the devices render shared pictures in turn according to the numbers and the preset current values of the shared numbers. The specific process of rendering the shared image by the multiple devices in turn is detailed in the related content of the aforementioned "mode two", and is not described here again.

According to the embodiment of the application, the process of sequencing and numbering the plurality of main devices is arranged on one side of the server to be executed, so that the pressure on the side of the devices can be relieved, and the processing resources of the devices are further saved.

Optionally, the determining a master device of the at least one device includes:

receiving first indication information sent by at least one device, wherein the first indication information is used for indicating that the device is set as a master device;

and determining the device which sends the first indication information in the at least one device as a master device.

Therefore, in the embodiment of the application, which device is set as the master device reports the indication information that the device is set as the master device to the server, so that the server can determine which devices are the master devices.

Optionally, after determining the master device in the at least one device, the method further includes:

generating a master device list and sending the master device list to each master device, wherein the master device list comprises identification information of the master devices.

Therefore, after receiving the first indication information which is set as the master device and reported by each device, the server may further generate a master device list according to the first indication information, and send the master device list to each device, so that each device may determine which devices are the master devices.

Optionally, the sorting the plurality of master devices according to a preset rule includes:

and sequencing the plurality of main devices according to the time sequence of the plurality of main devices set as the main devices.

The manner of sorting the plurality of master devices is not limited to this. For example, the sharing screen may be sorted randomly, or when the sharing screen is a sharing screen in a game, the sharing screen may be sorted according to a time sequence in which a plurality of master devices join the game, or when the sharing screen is a sharing screen in a video conference, the sharing screen may be sorted according to a time sequence in which a plurality of master devices join the conference.

Optionally, the method further includes:

receiving a device connection list sent by the at least one device, wherein the device connection list is a device connection list of a router of a local area network to which the device is connected;

and sending second indication information to each device under the condition that the device connection lists sent by each device are the same, wherein the second indication information is used for indicating that the at least one device is connected with the same local area network.

Therefore, in the embodiment of the present application, each device may send a list request to the router of the local area network to which each device is connected, so as to obtain the device connection list of the router of the local area network to which each device is connected, and report the device connection list to the server, so that the server determines whether the device connection lists received by the server are the same, if the device connection lists are the same, the devices are connected to the same local area network, and if the device connection lists are different, the devices are connected to different local area networks. After the server judges whether each device is connected with the same local area network, the server can send indication information for indicating whether the devices are connected with the same local area network to each device, so that when the devices are connected with the same local area network and a shared picture needs to be sent by the devices, the shared picture is sent through the local area network, and the loading speed of the shared picture is further increased.

According to the embodiment of the application, the process of judging whether each device is connected with the same local area network is set to be executed on one side of the server, so that the pressure on the device side can be relieved, and the processing resources of the devices are further saved.

As described above, the specific implementation of the method for displaying a shared screen according to the embodiment of the present application can be as described in the first implementation or the second implementation.

thereafter, for each frame subsequent to the first frame, the above-described steps H6 to H10 are performed.

That is, in the first embodiment, as shown in fig. 4, when there is one master device, the master device and the slave device request source data from the server, respectively, and when there is a preset share flag in the received source data, the master device renders a screen based on the source data and transmits the screen to the slave device, and the slave device discards the source data, receives the screen transmitted by the master device, and displays the screen. In the embodiment of the present application, there is no rendering speed gap due to the performance gap of the devices. Therefore, compared with the prior art, the embodiment of the application can shorten the speed gap of loading the same picture by each device.
