Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a screen projection system and method for multiple target terminals. Background Art

[0002] Screen projection refers to terminal A displaying the screen content on terminal B through a wireless-fidelity (WiFi) network or a wired connection.

[0003] In some usage scenarios, when terminal A projects the screen to terminal B, terminal A needs to display the same projected content at the same time. For example, in a remote conference, terminal A and terminal B need to play the same video at the same time. When terminal A projects the video content to terminal B, terminal A needs to play the video content at the same time so that the user using terminal A and the user using terminal B can watch the video content at the same time to achieve the goal of the remote conference.

[0004] The projection content is generally provided by the content provider. The server of the content provider sends a data packet to terminal A and terminal B through the public network. When terminal A and terminal B receive the data packet, they can start to display the projection content in the data packet. Currently, when terminal A projects the projection content to terminal B so that terminal A and terminal B display the projection content at the same time, control can only be achieved through terminal A, and terminal B cannot control the projection content, resulting in a poor user experience.

DETAILED DESCRIPTION

[0032] The embodiments of the present application provide a screen projection system and method for multiple target terminals, which are used to control the display of the projected content on the target terminal to which the screen is projected.

[0033] The embodiments of the present application are described below in conjunction with the accompanying drawings.

[0034] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, which is only to describe the distinction mode adopted by the objects of the same attributes when describing in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0035] The present application can be applied to a screen projection system for multiple target terminals, which includes a server and multiple target terminals. The server is used to send target screen projection content to at least one target terminal among the multiple target terminals, and at least one target terminal among the multiple target terminals that receives the target screen projection content can display the target screen projection content. In some possible implementations, the server can respond to a request from any one of the multiple target terminals to send the target screen projection content to at least one of the multiple target terminals; the server can also respond to a request from other devices other than the multiple target terminals to send the target screen projection content to at least one of the multiple target terminals; the server can also send the target screen projection content to at least one of the multiple target terminals spontaneously through user operation or based on a program; this is not limited here.

[0036] In the embodiment of the present application, a description is given by taking the multiple target terminals including a first target terminal and a second target terminal as an example. Figure 1 As shown, the screen projection system 100 for multiple target terminals includes a server 110, a first target terminal 120, and a second target terminal 130. In the embodiment of the present application, the communication between the server 110 and the first target terminal 120 and the second target terminal 130 can be achieved through a communication system. The communication system can be a public network or a local area network, which is not limited here.

[0037] In the embodiment of the present application, the server 110 can be a server, or a server cluster composed of several servers, or a cloud computing service center, which is not limited in the embodiment of the present application. Since the server 110 needs to respond to service requests and process them, and provide reliable services, generally speaking, the server 110 should have the ability to undertake services and guarantee services. The server 110 needs to have strong processing power, high stability, high reliability, high security, scalability and manageability. In the embodiment of the present application, the server 110 can be an x86 server, which is also called a complex instruction set computer (CISC) architecture server, that is, a personal computer (PC) server commonly referred to, which is based on the PC architecture and uses a processor chip of Intel or other compatible x86 instruction set and a windows operating system.

[0038] Taking the server 110 as an example, the server 110 may have relatively large differences due to different configurations or performances, and may include at least one central processing unit (CPU) (e.g., at least one processor) and memory, and at least one storage medium for storing applications or data (e.g., at least one mass storage device). Among them, the memory and the storage medium may be temporary storage or permanent storage. The program stored in the storage medium may include at least one module, and each module may include a series of instruction operations on the server 110. Furthermore, the central processing unit may be configured to communicate with the storage medium and execute a series of instruction operations in the storage medium on the server 110. The server 110 may also include at least one power supply, at least one wired or wireless network interface, at least one input and output interface, and / or at least one operating system, such as Windows Server, Mac OS X, Unix, Linux, FreeBSD, NetWare, etc. In some feasible implementations, the server 110 may also be a cloud server, which is not limited here.

[0039] In the embodiment of the present application, the first target terminal 120 or the second target terminal 130 is a device that can receive the target screen projection content and display the target screen projection content, the first target terminal 120 or the second target terminal 130 has data connectivity, and the first target terminal 120 or the second target terminal 130 is provided with a corresponding chip. Exemplarily, the first target terminal 120 or the second target terminal 130 can be: a mobile phone, a desktop computer, a tablet computer, a laptop computer, a PDA, a mobile internet device (mobile internet device, MID), a wearable device, a virtual reality (virtual reality, VR) device, an augmented reality (augmented reality, AR) device, a smart TV, etc., which are not limited here.

[0040] In some usage scenarios, when the first target terminal 120 projects the screen to the second target terminal 130, the first target terminal 120 needs to display the same projected content at the same time. For example, in a remote conference, the first target terminal 120 and the second target terminal 130 need to play the same video content at the same time. When the first target terminal 120 projects the video content to the second target terminal 130, the first target terminal 120 needs to play the video content at the same time, so that the user using the first target terminal 120 and the user using the second target terminal 130 can watch the video at the same time, so as to achieve the goal of the remote conference.

[0041] The projection content is generally provided by the content provider. The server 110 of the content provider sends a data packet to the first target terminal 120 and the second target terminal 130 through the public network. When the first target terminal 120 and the second target terminal 130 receive the data packet, they can start to display the projection content in the data packet. Currently, when the first target terminal 120 projects the projection content to the second target terminal 130 so that the first target terminal 120 and the second target terminal 130 display the projection content at the same time, control can only be achieved through the first target terminal 120, and the second target terminal 130 cannot control the projection content, resulting in a poor user experience.

[0042] In an embodiment of the present application, the first target terminal sends a screen projection instruction to the server, and the server sends the target screen projection content to the first target terminal and the second target terminal respectively based on the screen projection instruction. When the second target terminal plays the target screen projection content, it can send a first operation instruction regarding the target screen projection content to the server, so that the server sends the first control instruction to the first target terminal and the second target terminal respectively. Then, the first target terminal can perform the first control operation on the target screen projection content based on the first control instruction, and the second target terminal can perform the first control operation on the target screen projection content based on the first control instruction, thereby enabling the second target terminal whose screen is projected to control the target screen projection content on the first target terminal and the second target terminal.

[0043] See also Figure 2 As shown, a screen projection method for multiple target terminals provided in Embodiment 1 of the present application mainly includes the following steps: 201. The first target terminal sends a screen projection instruction to the server, where the screen projection instruction is used to instruct to project the target screen projection content to the first target terminal and the second target terminal.

[0044] In some possible implementations, when the first target terminal and the second target terminal use the same application, the first target terminal can generate a screen projection instruction related to the first target terminal and the second target terminal, and the first target terminal can send the screen projection instruction to the server, and the screen projection instruction is used to instruct to project the target screen projection content to the first target terminal and the second target terminal.

[0045] Exemplarily, the first target terminal establishes a virtual room or group, and the first target terminal sets the first target terminal and the second target terminal to the virtual room or group. Then, the first target terminal sends the screen projection instruction to the server, and the screen projection instruction includes indication information of the target screen projection content and the identifier of the virtual room or group, so as to instruct the server to send the corresponding target screen projection content to all target terminals in the virtual room or group.

[0046] It should be noted that the virtual room or group may include more than two target terminals, for example, three or more. In the embodiment of the present application, two target terminals are taken as an example.

[0047] Also exemplarily, the screen projection instruction includes indication information of the target screen projection content, an identifier of the first target terminal and an identifier of the second target terminal (exemplarily, the identifier can be a network protocol address) to instruct the server to send the target screen projection content to the first target terminal and the second target terminal.

[0048] In some possible implementations, the target screen projection content may be a video, a picture, an audio, etc., which is not limited here. For example, the target screen projection content is a video of a movie.

[0049] Exemplarily, the first target terminal is a mobile phone, and the second target terminal is a smart TV. The mobile phone and the smart TV are connected to the same home router, and the home router is connected to the server through the public network. The mobile phone sends the screen projection instruction to the server through the home router to instruct the server to send the target screen projection content to the mobile phone and the smart TV respectively.

[0050] In another exemplary embodiment, the first target terminal is a mobile phone, and the second target terminal is a laptop computer, and the mobile phone and the laptop computer are in different networks. The mobile phone sends the screen projection instruction to the server to instruct the server to send the target screen projection content to the mobile phone and the laptop computer respectively.

[0051] In some possible implementations, the first target terminal may send the screen projection instruction to the server under the operation of the user, or the first target terminal may send the screen projection instruction to the server under other triggering conditions based on preset functions, which is not limited here.

[0052] 202. The server sends the target screen projection content to the first target terminal and the second target terminal respectively based on the screen projection instruction.

[0053] In an embodiment of the present application, when the server receives a screen projection instruction, it can obtain the corresponding target screen projection content based on the indication information indicated in the screen projection instruction, and send the target screen projection content to the first target terminal and the second target terminal.

[0054] In some possible implementations, the server can also determine whether the first target terminal and the second target terminal are in the same network. If so, the server can send the target projection content to a network device (such as a home router) to which the first target terminal and the second target terminal are connected, thereby reducing traffic overhead.

[0055] In some possible implementations, if the server determines that the first target terminal and the second target terminal are in different networks, the server sends the target screen projection content to the first target terminal and the second target terminal respectively based on the screen projection instruction.

[0056] In some possible implementations, in order to ensure that the first target terminal and the second target terminal display the target projection content at the same time, before the server sends the target projection content to the first target terminal and the second target terminal respectively based on the projection instruction, the server can determine a first delay from the server to the first target terminal and a second delay from the server to the second target terminal, and send the target projection content to the first target terminal and the second target terminal respectively based on the first delay and the second delay, so as to ensure that the first target terminal and the second target terminal receive the target projection content at the same time and display the target projection content at the same time as much as possible.

[0057] Exemplarily, if the first delay is longer than the second delay, the server first sends the target screen projection content to the second target terminal, and after the duration of (first delay - second delay), the server sends the target screen projection content to the first target terminal. Another exemplary embodiment, if the first delay is shorter than the second delay, the server first sends the target screen projection content to the first target terminal, and after the duration of (second delay - first delay), the server sends the target screen projection content to the second target terminal.

[0058] Another exemplary method is that the target screen projection content may carry a start time point, and the start time point may be after the current time point max(first delay, second delay). Wherein, max(a,b) means taking the maximum value of a and b. Exemplarily, the current time point is t0, the first delay is t1, and the second delay is t2, where t1≥t2, and the start time point is x, then x≥t0+t1.

[0059] 203. The second target terminal receives the target screen projection content and displays the target screen projection content.

[0060] In some possible implementations, after the second target terminal receives the target projection content, the target projection content may be displayed immediately; in some possible implementations, after the second target terminal receives the target projection content, the target projection content may be displayed at the start playback time point indicated in the target projection content. This is not limited here.

[0061] 204. The first target terminal receives the target screen projection content and displays the target screen projection content.

[0062] In some possible implementations, after the first target terminal receives the target projection content, the target projection content may be displayed immediately; in some possible implementations, after the first target terminal receives the target projection content, the target projection content may be displayed at the start playback time point indicated in the target projection content. This is not limited here.

[0063] 205. When playing the target projection content, the second target terminal sends a first operation instruction regarding the target projection content to the server, where the first operation instruction is used to instruct a first control operation corresponding to the first operation instruction to be performed on the target projection content.

[0064] In some possible implementations, when the second target terminal is playing the target projection content, the user can operate the second target terminal so that the second target terminal generates a first operation instruction based on the user's operation, and the first operation instruction is used to instruct to perform a first control operation corresponding to the first operation instruction on the target projection content. Exemplarily, the first control operation may include at least one of pause, fast forward, rewind, exit, enter the next episode, and jump. For example, if the user clicks Pause on the screen of the second target terminal, the second target terminal generates a corresponding first operation instruction, and the first control operation corresponding to the first operation instruction is Pause.

[0065] In some possible implementations, the second target terminal may also receive operation signals from other devices (such as a mouse, a stylus, other terminals, etc.), so that the user can operate the second target terminal, so that the second target terminal generates a first operation instruction based on the user's operation, and the first operation instruction is used to instruct to perform a first control operation corresponding to the first operation instruction on the target projection content. This is not limited here.

[0066] In some possible implementations, the first operation instruction includes the first control operation and a first designated frame, and the first designated frame is a frame of the target projection content played by the second target terminal when the second target terminal sends the first operation instruction about the target projection content to the server. Exemplarily, the target projection content is a video, and the target projection content includes 10,000 frames, of which the first designated frame is the 5000th frame.

[0067] In some possible implementations, when the second target terminal plays the first designated frame of the target projection content, the user performs an operation on the second target terminal, so that the second target terminal generates a first operation instruction based on the user's operation, and the first operation instruction is used to instruct to perform a first control operation at the first designated frame of the target projection content.

[0068] Exemplarily, taking the first control operation of pause, fast forward or rewind as an example, if the first designated frame is the 5000th frame of the target projection content, the first operation instruction is to pause at the 5000th frame of the target projection content, fast forward at a specified rate starting from the 5000th frame of the target projection content, or rewind at a specified rate starting from the 5000th frame of the target projection content.

[0069] As another example, taking the first control operation of exiting, entering the next episode or jumping as an example, if the first designated frame is the 5000th frame of the target projection content, then the first operation instruction is to exit, enter the next episode at the 5000th frame of the target projection content, or to specify the number of frames forward or backward starting from the 5000th frame of the target projection content.

[0070] In some possible implementations, the first operation instruction may also include the first control operation, but not the first designated frame. Exemplarily, taking the first control operation as exiting, entering the next episode, or jumping as an example, if the first designated frame is the 5000th frame of the target projection content, the first operation instruction is to exit, enter the next episode, or jump from the target projection content to the target frame at the 5000th frame of the target projection content.

[0071] 206. The server sends a first control instruction to the first target terminal and the second target terminal respectively, where the first control instruction is used to perform the first control operation on the target projection content.

[0072] In an embodiment of the present application, after the server receives the first operation instruction sent by the second target terminal, the server may send a first control instruction to the first target terminal and the second target terminal respectively, and the first control instruction is used to perform the first control operation on the target projection content. In some possible implementations, the first control instruction may include a first control operation, or the first control instruction includes a first control operation and a first specified frame, which is not limited here.

[0073] It should be noted that a control and forwarding (control&user, CU) separation system is built into the server to achieve control and forwarding separation. Among them, the CU separation system includes a control plane (control plain, CP) and a user plane (user plain, UP). The user (first target terminal, second target terminal) is connected to the UP. The UP sends the received first operation instruction to the CP, allowing the CP to perform service processing, and the UP only handles the forwarding service. Then, the CP can process based on the first operation instruction to obtain the first control operation therein, or obtain the first control operation and the first specified frame therein, and generate a first control instruction based on the first operation instruction, and send the first control instruction to the UP, so that the UP sends it to the first target terminal and the second target terminal.

[0074] In some possible implementations, the server may also determine whether the first target terminal and the second target terminal are in the same network. If so, the server may send the first control instruction to a network device (such as a home router) to which the first target terminal and the second target terminal are connected, thereby reducing traffic overhead.

[0075] In some possible implementations, if the server determines that the first target terminal and the second target terminal are in different networks, the server sends the first control instruction to the first target terminal and the second target terminal respectively based on the first operation instruction.

[0076] In some possible implementations, in order to ensure that the first target terminal and the second target terminal display the first control instruction at the same time, before the server sends the first control instruction to the first target terminal and the second target terminal respectively based on the first operation instruction, the server may determine a first delay from the server to the first target terminal and a second delay from the server to the second target terminal, and send the first control instruction to the first target terminal and the second target terminal respectively based on the first delay and the second delay, so as to ensure that the first target terminal and the second target terminal receive the first control instruction at the same time and display the first control instruction at the same time as much as possible.

[0077] Exemplarily, if the first delay is longer than the second delay, the server first sends the first control instruction to the second target terminal, and after a duration of (first delay-second delay), the server sends the first control instruction to the first target terminal. Another exemplary embodiment, if the first delay is shorter than the second delay, the server first sends the first control instruction to the first target terminal, and after a duration of (second delay-first delay), the server sends the first control instruction to the second target terminal.

[0078] In another exemplary embodiment, the first control instruction may carry a start playback time point, and the start playback time point may be after the current time point max(first delay, second delay). Wherein, max(a,b) represents the maximum value of a and b. In another exemplary embodiment, the current time point is t0, the first delay is t1, and the second delay is t2, where t1≥t2, and the start playback time point is x, then x≥t0+t1.

[0079] 207. The first target terminal performs the first control operation on the target projection content based on the first control instruction.

[0080] Exemplarily, if the first control operation is to exit, enter the next episode or jump, and does not include the first designated frame, then after receiving the first control instruction, the first target terminal exits the target projection content, enters the next episode of the target projection content, or jumps to the target frame specified by the first control operation of the target projection content.

[0081] As another example, if the first control operation is pause, fast forward, rewind, exit, go to the next episode, jump, and includes a first designated frame, then after the first target terminal receives the first control instruction, it pauses at the first designated frame, fast forward / rewind at a specified rate from the first designated frame, exits the target projection content / goes to the next episode at the first designated frame, or advances or rewinds a specified number of frames from the first designated frame, without limitation here.

[0082] 208. The second target terminal performs the first control operation on the target projection content based on the first control instruction.

[0083] Exemplarily, if the first control operation is to exit, enter the next episode or jump, and does not include the first specified frame, then after receiving the first control instruction, the second target terminal exits the target projection content, enters the next episode of the target projection content, or jumps to the target frame specified by the first control operation of the target projection content.

[0084] As another example, if the first control operation is pause, fast forward, rewind, exit, go to the next episode, jump, and includes a first designated frame, then after the second target terminal receives the first control instruction, it pauses at the first designated frame, fast forward / rewind at a specified rate from the first designated frame, exits the target projection content / goes to the next episode at the first designated frame, or moves forward or backward a specified number of frames from the first designated frame, without limitation here.

[0085] In an embodiment of the present application, the first target terminal sends a screen projection instruction to the server, and the server sends the target screen projection content to the first target terminal and the second target terminal respectively based on the screen projection instruction. When the second target terminal plays the target screen projection content, it can send a first operation instruction regarding the target screen projection content to the server, so that the server sends the first control instruction to the first target terminal and the second target terminal respectively. Then, the first target terminal can perform the first control operation on the target screen projection content based on the first control instruction, and the second target terminal can perform the first control operation on the target screen projection content based on the first control instruction, thereby enabling the second target terminal whose screen is projected to control the target screen projection content on the first target terminal and the second target terminal.

[0086] In the embodiment of the present application, not only the second target terminal can control the target projection content, but the first target terminal can also control the target projection content. Figure 3 As shown, a screen projection method for multiple target terminals provided in Embodiment 1 of the present application mainly includes the following steps: 301. The first target terminal sends a screen projection instruction to the server, where the screen projection instruction is used to instruct to project the target screen projection content to the first target terminal and the second target terminal.

Exemplarily, the second control operation may include at least one of pause, fast forward, rewind, exit, enter the next episode, and jump. For example, if the user clicks Pause on the screen of the first target terminal, the first target terminal generates a corresponding second operation instruction, and the second control operation corresponding to the second operation instruction is Pause.

[0093] In some possible implementations, the first target terminal may also receive operation signals from other devices (such as a mouse, a stylus, other terminals, etc.), so that the user can operate the first target terminal, so that the first target terminal generates a second operation instruction based on the user's operation, and the second operation instruction is used to instruct the target projection content to perform a second control operation corresponding to the second operation instruction. This is not limited here.

[0094] In some possible implementations, the second operation instruction includes the second control operation and a second designated frame, and the second designated frame is a frame of the target projection content played by the first target terminal when the first target terminal sends the second operation instruction about the target projection content to the server. Exemplarily, the target projection content is a video, and the target projection content includes 10,000 frames, wherein the second designated frame is the 5000th frame.

[0095] In some possible implementations, when the first target terminal plays the second designated frame of the target projection content, the user performs an operation on the first target terminal, so that the first target terminal generates a second operation instruction based on the user's operation, and the second operation instruction is used to instruct to perform a second control operation at the second designated frame of the target projection content.

[0096] Exemplarily, taking the second control operation of pause, fast forward or rewind as an example, if the second designated frame is the 5000th frame of the target projection content, the second operation instruction is to pause at the 5000th frame of the target projection content, fast forward at a specified rate starting from the 5000th frame of the target projection content, or rewind at a specified rate starting from the 5000th frame of the target projection content.

[0097] As another example, taking the second control operation of exiting, entering the next episode or jumping as an example, if the second designated frame is the 5000th frame of the target projection content, the second operation instruction is to exit, enter the next episode at the 5000th frame of the target projection content, or to specify the number of frames forward or backward starting from the 5000th frame of the target projection content.

In some possible implementations, the second control instruction may include a second control operation, or the second control instruction includes a second control operation and a second specified frame, which is not limited here.

[0101] It should be noted that a control and forwarding (control&user, CU) separation system is built into the server to achieve control and forwarding separation. Among them, the CU separation system includes a control plane (control plain, CP) and a user plane (user plain, UP). The user (first target terminal, first target terminal) is connected to the UP. The UP sends the received second operation instruction to the CP, allowing the CP to perform service processing, and the UP only handles the forwarding service. Then, the CP can process based on the second operation instruction to obtain the second control operation therein, or obtain the second control operation and the second specified frame therein, and generate a second control instruction based on the second operation instruction, and send the second control instruction to the UP, so that the UP sends it to the first target terminal and the second target terminal.
