In the related art, if a terminal needs to share a game video stream to other terminals, the terminal typically pushes the game video stream to the other terminals while sending an operation instruction to a cloud server. Therefore, power consumption of the terminal is excessively high for such simultaneous operations.

A method for displaying a screen according to an embodiment of the present disclosure may be applicable to an application environment as shown in FIG. 1. A first client 101 and a second client 103 interact with a first server 102 over a network, and the first server 102 interacts with a second server 104. In some embodiments, the second server 104 may be a cloud game server where a game is installed, and the first server 102 may acquire a game video stream from the second server 104 and send the game video stream to the first client 101 and the second client 103 which are communicatively connected to the first server 102; the first client 101 and the second client 103 may display a game screen corresponding to the game video stream; the first client 101 or the second client 103 may acquire a game operation instruction for the game screen and return the game operation instruction to the first server 102; the first server 102 may send the game instruction to the second server 104; the second server 104 may update the game video stream based on the game operation instruction and send an updated target game video stream to the first server 102; the first server 102 may return the target game video stream to the first client 101 and the second client 103; and the first client 101 and the second client may display a game screen corresponding to the target game video stream. It should be noted that the process of displaying the game screen corresponding to the game video stream is explained by taking a game scenario as an example. In addition, the method for displaying the screen according to embodiments of the present disclosure may also be applicable to other scenarios, such as displaying a multimedia screen corresponding to a multimedia video stream in the scenario of watching multimedia data. The first client 101 and the second client 103 may include, but are not limited to, various personal computers, laptops, smartphones, tablet computers, and portable wearable devices, and the first server 102 and the second server 104 may be implemented by independent servers or a server cluster composed of a plurality of servers. The first client 101 is associated with the second client 103. For example, in a live-streaming scenario, the first client 101 is an anchor client and the second client 103 is an audience client associated with the anchor client. The first client 101 and the second client 103 may run on various electronic devices, which are, for example, terminals such as personal computers, laptops, smartphones, tablet computers, or portable wearable devices.

FIG. 2 is a flowchart of a method for displaying a screen according to an exemplary embodiment. As shown in FIG. 2, the method for displaying the screen is executed by a first client, and includes the following processes.

In S201, the first client 101 displays a first screen corresponding to a first video stream, wherein the first screen is also displayed on a second client 103 associated with the first client 101.

The first client 101 and the second client 103 share the first video stream, i.e., both the first client 101 and the second client 103 display the first screen corresponding to the first video stream. The first video stream may be any type of video stream, e.g., a game video stream or a multimedia video stream, and the first screen corresponding to the game video stream is a game screen.

The first client 101 is associated with the second client 103. That is, the first client 101 and the second client 103 may display a screen corresponding to the same video stream. The first client 101 may be associated with one second client 103 or a plurality of different second clients 103. In some embodiments, the second client 103 and the first client 101 are disposed in the same virtual space, and for example, the second client 103 and the first client 101 that are disposed in the same live-streaming room or in the same online meeting room may synchronously display the first screen corresponding to the first video stream.

In an exemplary embodiment, the first client 101 receives the first video stream from the first server 102, wherein the first video stream is acquired by the first server 102 from the second server 104, and the first server is further configured to send the first video stream to the second client 103.

The first video stream is acquired from the second server 104 that is configured to provide services for the first client 101. The first server 102 is a server that exchanges information with the first client 101 and the second server 104 separately. The first client 101 does not communicate with the second server 104 directly, but communicate with the first server 102. In a game scenario, the second server is a game server, the first video stream is a game video stream corresponding to a game installed in the second server 104, the first client 101 is a client for feeding back a game operation instruction to a game screen, and the first client 101 and the second client 103 acquire the game video stream for displaying the game screen from the second server 104 by the first server 102 and display the game screen corresponding to the acquired game video stream.

In S202, the first client 101 acquires an operation instruction for the first screen, and sends the operation instruction to the first server 102.

The first server 102 is configured to send the operation instruction to the second server 104, receive a first target video stream from the second server 104, and send the first target video stream to the first client 101 and the second client 103. The first target video stream is acquired by the second server 104 in response to the operation instruction. The second client 103 is configured to display a first target screen corresponding to the first target video stream. In a game scenario, the operation instruction for the first screen is a game operation instruction in response to the first screen being a game scenario.

The first target video stream is a video stream acquired by the second server 104 according to the operation instruction. In some embodiments, after displaying the first screen, the first client may acquire the operation instruction based on the displayed first screen. For example, the operation instruction may be acquired by the first client 101 in response to a user performing a triggering operation on the first screen, or may be generated by the first client 101 according to a preset program. The first client 101 may send the operation instruction to the first server 102 over a network, such that the first server 102 may send the operation instruction to the second server 104, and then the second server 104 may acquire the first target video stream according to the operation instruction, communicate with the first server 102, and then the first server 102 may return the first target video stream to the first client 101 and the second client 103.

In S203, the first client 101 receives the first target video stream from the first server 102, and displays a first target screen corresponding to the first target video stream.

The first server 102 returns the first target video stream to the first client 101, and the first client 101 can receive the first target video stream and display the first target screen corresponding to the first target video stream, i.e., the first target screen acquired in response to operating the first screen corresponding to the first video stream, i.e., the updated first screen.

The first target screen and the first screen belong to the same type of screens, and their difference lies in that the first screen is generated by the first video stream, the first target screen is generated by the first target video stream, and the contents of the first target screen and the first screen are different because the video streams are changed.

In the above method for displaying the screen, both the first client 101 and the second client 103 can display the first screen corresponding to the first video stream. In response to detecting the operation instruction for the first screen, the first client 101 may send the operation instruction to the second server 104 via the first server 102, such that the second server 104 may acquire the first target video stream and may enable the first server 102 acquire the first target video stream corresponding to the operation instruction from the first client 101. The first target video stream may be sent to the first client 101 and the second client 103, such that both the first client 101 and the second client 103 may display the first target screen corresponding to the first target video stream, which enables the first client 101 and the second client 103 to update the first screen synchronously. Therefore, the first client 101 does not need to push the video stream to the second client 103, reducing the power consumption of the electronic device where the first client 101 is disposed.

In an exemplary embodiment, the screen displaying method further comprises: in response to a first switching instruction, the first client 101 sends the first switching instruction to the first server, wherein the first switching instruction indicates that an operation authority is switched to a second target client. The first server 102 responds to the operation instruction from the second target client, based on the first switching instruction.

There may be a plurality of second clients 103 which include a second target client, and the second target client is one of the second clients 103 that can send the operation instruction. The first client 101 can transfer the operation authority to the second target client, and the second target client can send the operation instruction based on the first screen corresponding to the first video stream. In some embodiments, the first client 101 may acquire the first switching instruction, for example, the first switching instruction may be generated by triggering of the user of the first client 101, and is configured to switch the game operation authority. In response to the first switching instruction, the first client 101 may send the first switching instruction to the first server 102. Based on the acquired first switching instruction, the first server 102 may respond to the operation instruction from the second target client and stop responding to the operation instruction from the first client 101. In some embodiments, the first client 101 may stop sending the operation instruction for the first screen to the first server 102 in response to the first switching instruction.

In some embodiments, the first client 101 receives an operation request from the second target client and displays the operation request, and in response to a confirmation instruction for the operation request, determines the confirmation instruction as the first switching instruction.

The operation request is configured to request switching the operation authority to the second target client. For example, the operation request is generated by a triggering operation by a user of the second target client. The operation request from the second target client may be displayed on an interface of the first client 101 in the form of a pop-up window. As shown in FIG. 3, on an exemplary first screen of the first client 101, in response to receiving the operation request from the second target client, the first client 101 may display the operation request on the first screen in the form of a pop-up window, and the user of the first client 101 may trigger an operation instruction for the operation request by clicking a button on the pop-up window. In response to detecting the confirmation instruction, the first client 101 may determine the confirmation instruction as the first switching instruction, and send the first switching instruction to the first server 102. As shown in FIG. 3, the pop-up window includes a confirmation button 301 and a rejection button 302. The first client 101 may determine that the confirmation instruction is detected in response to a triggering operation on the confirmation button 301. The first client 101 may determine that an operation rejection instruction is detected in response to a triggering operation on the rejection button 302, and thus refuse to switch the operation authority to the second target client.

In the above embodiment, the first client 101 may switch the operation authority to the second target client, and the second target client may request, by sending the operation request, the first client 101 to transfer the operation authority, such that an interaction between the first client 101 and the second client 103 is realized. In the case that the first client 101 is incapable of acquiring the operation instruction, a normal display of the first screen may be ensured by switching the operation authority, thereby improving the display fluency of the screen.

In an exemplary embodiment, the first server 101 is a live-streaming server, the first client 101 and the second client 103 are disposed in the same virtual space, and the first client 101 is an anchor client. In an exemplary embodiment, the second server 104 is a game server and the second client 103 is an audience client.

In an exemplary embodiment, as shown in FIG. 4, the method for displaying the screen further includes the following processes.

In S401, the first client 101 switches the first screen to a second screen corresponding to a second video stream in response to a second switching instruction. The second switching instruction indicates screen switching, and the second video stream is acquired by the electronic device where the first client 101 is disposed. For example, the electronic device where the first client 101 is disposed is an image acquisition device.

The second switching instruction is configured to switch the first screen displayed by the first client 101 to a screen acquired by the electronic device, for example, the second switching instruction may be generated by triggering of the user of the first client 101. In response to the second switching instruction, the electronic device may acquire the second video stream, e.g., by a camera in the electronic device, and may switch the first screen displayed by the first client 101 to the second screen corresponding to the second video stream. For example, in the game live-streaming scenario, the first server 102 is a live-streaming server for live-streaming, the first client 101 and the second client 103 are disposed in the same virtual space, e.g., in the same live-streaming room, the first client 101 is an anchor client, the first screen is a game screen, and the second screen corresponding to the second video stream is a shooting screen of the electronic device. The electronic device may switch the game screen displayed on the first client 101 to the shooting screen of the electronic device in response to the second switching instruction.

The second screen and the first screen are different types of screens. Since the first screen is generated by the first video stream and the second screen is generated by the second video stream, and the first video stream and the second video stream belong to different types of video streams, for example, the first video stream is a game video stream and the second video stream is a video stream shot by the electronic device, the first screen and the second screen are also of different types.

In S402, the first client 101 sends the second switching instruction and the second video stream to the first server 102, wherein the first server 102 is configured to send the second video stream to the second client 103, and stop sending the first video stream to the first client 101 and the second client 103 in response to the second switching instruction.

In response to receiving the second switching instruction, the first client 101 may also send the second switching instruction and the captured second video stream to the first server 102, such that the first server 102 may send the second video stream to the second client 103 (e.g., the audience client in the live-streaming room) based on the second switching instruction, and at the same time, stop sending the first video stream to the first client 101 and the second client 103. The second client may switch the first screen corresponding to the first video stream to the second screen corresponding to the second video stream based on the acquired second video stream.

In the above embodiment, the first client 101 may switch the first screen displayed by the first client 101 and the second client 103 to the second screen based on the second switching instruction, thereby realizing seamless switching between the first screen and the second screen. For example, during live-streaming of the game, seamless switching between the game screen and the shooting screen is realized.

In addition, in some embodiments, the first client 101 may display the second screen corresponding to the second video stream in the form of a floating window in the first screen in response to a third switching instruction, wherein the third switching instruction indicates that the first screen and the second screen are displayed simultaneously, and the second video stream is captured by the electronic device where the first client 101 is disposed.

As shown in FIG. 5, on an exemplary interface of the first client 101, by taking a game live-streaming scenario as an example, the first screen is a game screen and the second screen is a shooting screen. During carrying out the game live-streaming as the live-streaming client, the first client 101 may also display the shooting screen acquired by the image acquisition device corresponding to the first client 101 in the form of a floating window. That is, the game screen and the shooting screen are displayed simultaneously. In response to receiving the third switching instruction, the first client 101 may acquire the first video stream from the first server 102 and the second video stream from the image acquisition device simultaneously, such that the first client 101 may display the shooting screen corresponding to the second video stream in the game screen corresponding to the first video stream in the form of a floating window.

In embodiments of the present disclosure, while displaying the game screen, the first client 101 may display the shooting screen in the form of a floating window, which helps to improve the interestingness of the game live-streaming process.

In an exemplary embodiment, the first client 101 may further stop displaying the first screen, and switch the second screen from being displayed in the form of a floating window to being displayed in the form of a full screen in response to a second switching instruction, wherein the second switching instruction indicates screen switching.

In the case that the first client 101 displays the first screen and the second screen simultaneously, the first client 101 displays the second screen in the form of a floating window. In response to detecting the second switching instruction that indicates screen switching, the first client 101 stops displaying the first screen corresponding to the first video stream and switches the second screen from being displayed in the form of a floating window to being displayed in the form of a full screen.

FIG. 6 is a flowchart of a method for displaying a screen according to an exemplary embodiment of the present disclosure. As shown in FIG. 6, the method is applicable to a first server 102, and includes the following processes.

In S601, the first server 102 acquires a first video stream from a second server 104, and sends the first video stream to a first client 101 and a second client 103 associated with the first client 101.

The first server 102 acquires the first video stream from the second server 104 and sends the acquired first video stream to the first client 101 and the second client 103, such that the first client 101 and the second client 103 display a first screen corresponding to the first video stream. In a game scenario, the second server 104 is a game server, and the first server 102 acquires a game video stream corresponding to a game screen from the second server 104 where a game is installed.

In S602, the first server 102 receives an operation instruction for the first screen from the first client 101, and sends the operation instruction to the second server 104. The first screen is a screen corresponding to the first video stream, and the second server 104 is configured to acquire an updated first target video stream by updating the first video stream in response to the operation instruction.

After sending the first video stream to the first client 101, the first server 102 may receive the operation instruction for the first screen from the first client 101 and send the operation instruction to the second server 104, and the second server 104 may acquire the updated first target video stream by updating the first video stream based on the operation instruction.

In S603, the first server 102 acquires the first target video stream from the second server 104 and sends the first target video stream to the first client 101 and the second client 103.

The first server 102 acquires the updated first target video stream from the second server 104, and sends the first target video stream to the first client 101 and the second client 103, such that the first client 101 and the second client 103 may display the first target screen corresponding to the first target video stream, i.e., update the first screen corresponding to the first video stream to a screen corresponding to the target video stream.

In the above method for displaying the screen, both the first client 101 and the second client 103 may display the first screen corresponding to the first video stream. In response to detecting the operation instruction for the first screen, the first client 101 sends the operation instruction to the second server 104 via the first server 102, such that the first server 102 may acquire the first target video stream corresponding to the operation instruction from the second server 104. The first target video stream is sent to the first client 101 and the second client 103, such that both the first client 101 and the second client 103 may display the first target screen corresponding to the first target video stream, which enables the first client 101 and the second client 103 to update the first screen synchronously. Therefore, the first client 101 does not need to push the video stream to the second client 103, reducing the power consumption of the electronic device where the first client 101 is disposed.

In an exemplary embodiment, the first server 102 may receive a first switching instruction from the first client 101, wherein the first switching instruction indicates that an operation authority is switched to a second target client. Based on the first switching instruction, the first server 102 responds to an operation instruction from the second target client.

The first client 101 may transfer the operation authority to the second target client, and the second target client may send the operation instruction based on the first screen corresponding to the first video stream. The first client 101 sends the first switching instruction to the first server 102. The first server 102 may respond to the operation instruction for the first screen corresponding to the first video stream from the second target client in response to receiving the first switching instruction, and stop responding to the operation instruction from the first client 101, thereby completing the switching of the operation authority. In some embodiments, the first client 101 may send the first switching instruction to the first server 102, and stop sending the operation instruction for the first screen to the first server 102 in response to the first switching instruction, such that the first server 102 will no longer receive the operation instruction from the first client 101, and thus, will not need to respond to the operation instruction from the first client 101.

In the above embodiment, the first client 101 may switch the operation authority to the second target client. In the case that the first client 101 is incapable of capturing the game operation instruction, the normal display of the first screen may be ensured by switching the operation authority, thereby improving the display fluency of the screen.

In an exemplary embodiment, the first server 102 is a live-streaming server, the first client 101 and the second client 103 are disposed in the same virtual space, and the first client 101 is an anchor client. In an exemplary embodiment, the second server 104 is a game server and the second client 103 is an audience client.

In an exemplary embodiment, the first server 102 may receive a second switching instruction and a second video stream from the first client 101, wherein the second video stream is captured by the electronic device where the first client 101 is disposed. The first server 102 may send the second video stream to the second client 103, and stop sending the first video stream to the first client 101 and the second client 103. For example, the electronic device where the first client 101 is disposed is an image acquisition device.

The second switching instruction is configured to switch the first screen displayed by the first client 101 to a screen captured by the electronic device. For example, the second switching instruction is generated by triggering of the user of the first client 101. For example, in a game live-streaming scenario, the first server 102 is a live-streaming server, the first client 101 and the second client 103 correspond to the same live-streaming room, the first client 101 is an anchor client of an anchor and the second client 103 is an audience client of the audience. The first screen is a game screen, the second screen corresponding to the second video stream is a shooting screen of the electronic device, and the second switching instruction is configured to switch the game screen to the shooting screen. In response to receiving the second switching instruction from the first client 101, the first server 102 acquires the second video stream from the first client 101, sends the second video stream to the second client 103, and stops sending the first video stream to the first client 101 and the second client 103, such that the second client 103 switches the displayed game screen to the shooting screen corresponding to the first video stream.

In an exemplary embodiment, as shown in FIG. 7, the first server 102 sends the first video stream or the first target video stream to the first client 101 and the second client 103, and the method further includes the following processes.

In S701, the first server 102 acquires the second video stream from the first client 101.

The second video stream is captured by the electronic device where the first client 101 is disposed, and the first client 101 sends the second video stream to the first server 102.

In S702, the first server 102 acquires a second target video stream by adding the second video stream to the first video stream or the first target video stream. In a second target screen corresponding to the second target video stream, a second screen corresponding to the second video stream is displayed in the first screen of the first video stream or the first target video stream in the form of a floating window.

In S703, the first server 102 sends the second target video stream to the first client 101 and the second client 103.

The second target video stream is acquired by the first server 102 by processing the first video stream or the first target video stream acquired from the second server 104 and the second video stream acquired from the first client 101. In some embodiments, the first server 102 may form the second target video stream by adding the second video stream into the first video stream or the first target video stream, and send the second target video stream to the first client 101 and the second client 103, such that the first client 101 and the second client 103 may display the second screen corresponding to the second video stream in the first screen in the form of a floating window based on the second target video stream. For example, in a game live-streaming scenario, the first screen is a game screen, the second screen corresponding to the second video stream is a shooting screen of the electronic device.

That is, the first server 102 acquires the second video stream from the first client 101 and sends the second video stream to the second client 103. The second screen corresponding to the second video stream is configured to be displayed on the first screen in the form of a floating window, and the second video stream is captured by the electronic device where the first client is disposed. Therefore, in response to receiving the second video stream, the second client 103 displays the second screen corresponding to the second video stream in the first screen in the form of a floating window.

In addition, the first server 102 may send the second video stream to the second client 103 and stop sending the first video stream to the first client 101 and the second client 103 in response to the second switching instruction from the first client 101. The second screen corresponding to the second video stream is switched from being displayed in the form of a floating window to being displayed in the form of a full screen.

In the case that the second client 103 displays the second screen corresponding to the second video stream in the form of a floating window, in response to receiving the second switching instruction from the first client 101, the first server 102 directly sends the second video stream to the second client 103, and at the same time, stops sending the first video stream to the first client 101 and the second client 103. Meanwhile, the second client 103 switches the second screen from being displayed in the form of a floating window to being displayed in the form of a full screen in response to acquiring the second video stream.
