Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

The terms "first," "second," "third," and "fourth" and the like in the description and in the claims and drawings are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

As used in this specification, the terms "component," "module," "system," and the like are intended to refer to a computer-related entity, either hardware, firmware, a combination of hardware and software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between 2 or more computers. Furthermore, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate by way of local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from two components interacting with one another in a local system, distributed system, and/or across a network such as the internet with other systems by way of the signal).

With the continuous popularization of wireless networks, the WIFI coverage degree in the office network of a user is higher and higher; in conventional video applications, connection between a PC or a content sharing device and a display device (hereinafter also referred to as a destination device) is often required by means of an HDMI, VGA or the like cable. Therefore, there is a strong need for wireless screen transfer in a conference room, or wireless content sharing in a video conference scenario. For example, in a meeting room office scenario, because of the gap between HDMI and VGA interfaces, the user's office needs to deploy multiple cables, intertwine, and be messy. And different devices have different types of interfaces, if the cable does not support the interfaces, the screen cannot be transmitted through the cable. For example, in a video conference scenario, a video conference terminal is often placed on a cabinet at a corner of a conference room, and decoration modification of the conference room is very large by disposing an HDMI (high definition multimedia interface) or a VGA (video graphics array) wire, and is limited by the lengths of the HDMI wire and the VGA wire. Based on the current situation, the wireless screen transmission system provided by the application is provided with the WIFI6 technology so as to realize wireless screen transmission among source equipment, cooperative equipment and target equipment. Here, wi-Fi 6 (originally, IEEE 802.11. Ax), a sixth generation wireless network technology, is a name of Wi-Fi standard. Is a wireless local area network technology created by Wi-Fi alliance in the IEEE 802.11 standard. Wi-Fi 6 will allow communication with up to 8 devices, with a highest rate of up to 9.6Gbps. Wi-Fi 6 mainly uses OFDMA, MU-MIMO (multi-user multiple input multiple output) technology, which allows a router to communicate with multiple devices at the same time, rather than sequentially. MU-MIMO allows a router to communicate with four devices at a time, wi-Fi 6 will allow communication with up to 8 devices. Wi-Fi 6 also utilizes other techniques, such as OFDMA (orthogonal frequency division multiple access) and transmit beamforming, which function to improve efficiency and network capacity, respectively. The highest Wi-Fi 6 speed can reach 9.6Gbps.

In order to better understand the cooperative method of the embodiment of the present application, the following is a simple description of a possible application scenario of the embodiment of the present application with reference to fig. 1:

Application scenario one: as shown in fig. 1, devices T1, T2, T3, T4 and T5 together form a wireless screen transmission system, specifically, device T1 may be a smart phone, device T2 may be a camera, device T3 may be a projector, device T4 may be a common sound box, and device T5 may be a common display screen. The device T1 is a source device, and the source device is configured to respond to a play task initiated by a user, and perform cooperative processing on the play task to obtain a target cooperative device, so that the target cooperative device may cooperate with itself to transmit a multimedia resource to a destination device (e.g., a projector). In general, these devices may form a wireless screen-transfer system through a hotspot or router of a certain device. Specifically, the device T1 may perform networking by sending a broadcast message to each cooperative device, and after the networking is successful, the device T1 sends synchronization time synchronization information (for example, a handshake message) to each cooperative device to perform network synchronization. After successful networking and synchronization is completed, each cooperative device in the wireless screen-throwing system responds to a play task initiated by a user through the device T1.

Taking the application scenario shown in fig. 1 as an example, please refer to fig. 2, which is a schematic flow chart of a method for cooperative work provided in an embodiment of the present application, the method is applied to a wireless screen transmission system, where the wireless screen transmission system includes a source device, at least one cooperative device, and a destination device, and a transmission data transmission link is established between the source device, the at least one cooperative device, and the destination device through a wireless transmission network connection, and may include, but is not limited to, the following steps:

step S201, the source equipment receives a playing instruction of a user for the multimedia resource.

Step S202, the source equipment responds to the playing instruction to acquire the target cooperative equipment from at least one cooperative equipment, wherein the computing capacity and/or the data transmission rate of the target cooperative equipment are/is greater than those of the source equipment, and multimedia resources are stored in the target cooperative equipment.

In one embodiment, the implementation process of acquiring the target cooperative device in the at least one cooperative device may include: firstly, the source equipment acquires the computing capacity and/or the data transmission rate corresponding to each cooperative equipment; and secondly, the source device can compare the computing capacity and/or the data transmission rate of the source device with the computing capacity and/or the data transmission rate corresponding to each cooperative device, and further judge whether the cooperative devices store multimedia resources at the same time, and acquire a first candidate device based on the comparison result and the judgment result, wherein the computing capacity and/or the data transmission rate of the first candidate device is greater than that of the source device, and the first candidate device stores the multimedia resources, and in this case, the first candidate device is the target cooperative device. In the implementation mode, the computing capacity and/or the data transmission rate of the cooperative equipment are fully considered, so that the transmission reliability in the wireless screen transmission process can be improved; in addition, because the multimedia resources are stored in the cooperative device, compared with the implementation mode that the source device sends the multimedia resources to the cooperative device in real time, the transmission speed can be improved.

In one embodiment, the process of obtaining the target cooperative device in at least one cooperation may include: firstly, the source equipment acquires the computing capacity and/or the data transmission rate corresponding to each cooperative equipment; secondly, the source device can compare the calculation capability and/or the data transmission rate of the source device with the calculation capability and/or the data transmission rate corresponding to each cooperative device, and further judge whether the cooperative device stores multimedia resources at the same time, and acquire a first candidate device based on the comparison result and the judgment result, wherein the calculation capability and/or the data transmission rate of the first candidate device is greater than that of the source device, and the first candidate device stores multimedia resources; then, in the first candidate device, acquiring a cooperation performance parameter between each candidate device and the target device, wherein the cooperation performance parameter indicates a signal-to-interference ratio and a channel rate of a data transmission link between each candidate device and the target device; and finally, acquiring the target cooperative equipment based on the cooperative performance parameters. In one embodiment, the candidate device corresponding to the top M bits of the collaboration performance parameter may be determined as the target collaboration device, where M is an integer greater than 0, for example, the collaboration performance parameter of candidate device 1 is a, the collaboration performance parameter of candidate device 2 is b, the collaboration performance parameter of candidate device 3 is c, where a > b > c, and the source device may determine candidate device 1 and candidate device 2 as the target collaboration device. In one embodiment, a candidate device corresponding to a collaboration performance parameter greater than a preset threshold may be determined as a target collaborative device. For example, the cooperative performance parameter of the candidate device 1 is a, the cooperative performance parameter of the candidate device 2 is b, and the cooperative performance parameter of the candidate device 3 is c, where a > b > c, the preset threshold is b, and the source device may determine the candidate device 1 as the target cooperative device. In the implementation mode, the computing capacity and/or the data transmission rate and the cooperation performance parameters of the cooperative equipment are fully considered, so that the transmission reliability in the wireless screen transmission process can be improved; in addition, because the multimedia resources are stored in the cooperative device, compared with the implementation mode that the source device sends the multimedia resources to the cooperative device in real time, the transmission speed can be improved.

In step S203, the source device instructs the target cooperative device to cooperate with itself to transmit the multimedia resource to the target device.

In one embodiment, the implementation procedure of the source device to instruct the target cooperative device to transmit the multimedia resource to the target device together with itself may include the following steps:

step S203-11: the source equipment sends screen transmission data frame information for transmitting the multimedia resource to the target cooperative equipment, wherein each screen transmission data frame information comprises intercepted audio and video data, a time point when each audio and video data is transmitted and the maximum allowable time delay for transmitting each audio and video data;

Step S203-12: the target cooperative device receives the screen transmission data frame information and transmits the multimedia resource to the target device according to the transmission data frame information and the source device.

Step S203-13: the destination device receives the multimedia resources sent by the source device and the target cooperative device.

In this implementation manner, because the frame information of the screen transmission data contains the time point when each audio and video data is transmitted, the destination device can be ensured to receive the same audio and video data at the same time, the situation of inconsistent data can be avoided, the destination device can conveniently combine the received audio and video data, and the destination device can display the processed audio and video data on a screen.

step S203-21: the source equipment acquires the play resolution data of the destination equipment;

Step S203-22: the source equipment determines screen transmission data frame information for transmitting the multimedia resource according to the play resolution data of the destination equipment, wherein each screen transmission data frame information comprises intercepted audio and video data and the time for executing the intercepting action of each audio and video data, and the maximum allowable time delay for transmitting each audio and video data is transmitted;

step S203-23: the target cooperative device receives the screen transmission data frame information and transmits the multimedia resource to the target device according to the transmission data frame information and the source device.

Step S203-24: the destination device receives the multimedia resources sent by the source device and the target cooperative device.

In this implementation manner, since the frame information of the screen-transfer data includes the time of executing the intercepting action of each piece of audio/video data, for the destination device, the received audio/video data can be combined based on the time of executing the intercepting action of each piece of audio/video data, so that the destination device can perform screen display on the processed audio/video data. Because the screen transmission data frame information is determined based on the playing resolution data of the target equipment, the display effect of the audio and video data played by the target equipment can be improved.

In the following, in conjunction with the method flowchart shown in fig. 3, it is specifically described how, in an embodiment of the present application, a collaboration conflict is resolved, where the collaboration conflict is reflected in that the target collaboration device is unavailable, where the method may include, but is not limited to, the following steps:

Step S300, when the destination cooperative device for cooperative transmission is determined to be unavailable, the source device transmits the multimedia resource to the destination device.

In this implementation, normal transmission of multimedia resources may be guaranteed.
