Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.
It is to be understood that the terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
With the continuous development and perfection of modern wireless communication technology, the wireless screen-throwing technology is gradually applied to various life, study and work scenes, and the wireless screen-throwing technology can throw conference contents, multimedia files and game pictures on another screen for presentation, so that interaction is performed without various physical connection lines, and the screen-throwing experience is free from constraint and enjoyed more quickly and freely. Wireless screen projection technology has been closely related to our lives, providing more convenience for work and entertainment. Based on different wireless communication technologies and different standards, the existing screen-casting technology on the market takes AirPlay of apple company, miracast of Wi-Fi alliance, DLNA of digital living network alliance and Chromecast of Google as the leading technologies, and the emerging 60GHz millimeter wave screen-casting technology, WHDI protocol and other abundant and various wireless screen-casting technologies.
The existing large wireless screen-throwing protocols based on different standards and organizations have distinct characteristics and distinct advantages and disadvantages.
Firstly, DLNA (DIGITAL LIVING NETWORK ALLIANCE) is a ALLIANCE organization consisting of consumer electronics, mobile phones and computer manufacturers, and its members include philips, samsung electronics, sony and intel, so that the DLNA screen-projection protocol has wide adaptability across devices and brands; the DLNA is based on a local area network, which can be 802.3 ethernet, 802.11WiFi or 802.15 bluetooth, so that the connection mode of the DLNA also shows its wide adaptability, but the characteristics that the inter-device communication is based on the local area network and the discovery and control between devices is based on uPnP are also disadvantages, that is, devices of different local area networks cannot be screened, the transmission content of the devices is limited to files (video files, picture files, etc.), and meanwhile, the depending uPnP protocol makes hot plug devices between the screened devices and the playing devices necessary.
Secondly, the Airplay, which is a non-open source private protocol family, can only be used in individual products of apple families and a few cooperators, and the screen-throwing equipment and the screen also need to be in the same local area network, namely the same wifi hotspot, and compared with other wireless screen-throwing protocols, the Airplay has the advantages of mainly safety and the mirror function of supporting the mobile phone screen.
The corresponding Chromecast is also a private protocol, he no longer requires the screen-throwing device to be located under the same local area network with the screen, but he actually requires both to be in a networking state, the pushing of the screen-throwing device is essentially initiated by the network end, the screen-throwing device sends the media content to be thrown to the google server and then the server informs the receiving end to play, so that the receiving end cannot directly play the screen-throwing content and a special app is needed. For millimeter wave projection, his advantages are evident: low latency, large bandwidth, high image quality, strong interference immunity, etc., but he does not base on the existing mature wifi, bluetooth, etc. wireless communication technologies and therefore needs to purchase an additional whole set of equipment specifically for screen projection.
Finally, the Miracast is based on wifi-p2p technology, the screen throwing among devices is realized, and because the wifi protocol supports coexistence of p2p and sta modes, the Miracast can theoretically eliminate the need of the screen throwing device to be located under the same wifi hot spot with a playing end, and in addition, the Miracast can throw the mirror image of the screen throwing device to the playing end without transmitting the media file like the Airplay. Miracast is used as an open source protocol, and is well applied to all devices of all platforms except apples, and has the defect that the protocol itself does not have clear requirements on compatibility, so that all manufacturers may not be fully compatible with each other.
The common wireless screen-throwing mode is analyzed, and the fact that although various screen-throwing protocols have own advantages and disadvantages can be found, the application scene of the method is mostly limited between two devices, namely 1v1 of one screen-throwing device and 1v1 of one playing device, 2v1, 1v2 and NvN of a plurality of devices are not described, the idea of everything interconnection is maintained, and Kaihong OS develops and innovates the Miracast wireless screen-throwing protocol based on an Openhardy system, so that a cross-platform and cross-device multi-screen interaction scheme is realized.
The embodiment of the application provides a data transmission method, display equipment and storage medium based on wireless screen projection. The data transmission method based on wireless screen projection can be applied to display equipment, and the display equipment can be a tablet personal computer, a notebook computer, a personal digital assistant, wearable equipment and a television.
The embodiment of the application provides a data transmission method, display equipment and storage medium based on wireless screen projection, wherein after the screen projection connection is established between the display equipment and first screen projection equipment and second screen projection equipment, a first screen projection icon corresponding to the first screen projection equipment and a second screen projection icon corresponding to the second screen projection equipment are displayed in a first display area of a display screen of the display equipment; when a file selection instruction is received through operation on a display screen of the display device, determining a target file matched with the file selection instruction from files stored in the first screen throwing device according to the file selection instruction; when a file transmission instruction of the target file is received, the target file is acquired from the first screen throwing device according to the file transmission instruction, and the target file is transmitted to the second screen throwing device by taking the display device as a transfer point of the target file. According to the method and the device, after the first screen throwing equipment and the second screen throwing equipment are connected to the display equipment, the first screen throwing equipment and the second screen throwing equipment are associated through the display equipment, so that data transmission between the first screen throwing equipment and the second screen throwing equipment can be achieved through the display equipment, the first screen throwing equipment and the second screen throwing equipment can be out of a local area network, the efficiency of data transmission in wireless screen throwing is improved, the working efficiency between cross-regional workers is improved, and the deployment cost is reduced.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flow chart of a data transmission method based on wireless screen projection according to an embodiment of the present application.
As shown in fig. 1, the data transmission method based on wireless screen projection includes steps S1 to S3.
Step S1: after the display equipment is connected with the first screen throwing equipment and the second screen throwing equipment, displaying a first screen throwing icon corresponding to the first screen throwing equipment in a first display area of a display screen of the display equipment, and displaying a second screen throwing icon corresponding to the second screen throwing equipment in a second display area of the display screen of the display equipment.
The first screen throwing device and the second screen throwing device correspondingly display the content on the first screen throwing device and correspondingly display the content on the second screen throwing device on the display screen of the display device after the connection with the display device is established, wherein the first display area and the second display area can be displayed according to the area defined by the display device, and the first screen throwing device and the second screen throwing device can also select the corresponding first display area and second display area on the display device to throw the screen.
For example, the display device uniformly divides the display screens according to the number of the screen throwing devices, so that the content display of the screen throwing devices is realized. The display device can divide the display area automatically according to the content of the screen throwing device to be displayed without limiting the division of the display area.
Alternatively, as shown in fig. 2, the display screen of the display device 10 includes a first display area corresponding to the first screen projecting device 20 and a second screen projecting device corresponding to the second screen projecting device 30, where the first display area and the second display area may overlap.
Alternatively, the first display area and the second display area in the display apparatus 10 may be set so as not to overlap, and when the first display area and the second display area overlap, the first display area and the second display area are brought into close proximity by themselves, as shown in fig. 3. Specifically, whether the first display area and the second display area can be overlapped or not can be set in the display device according to the requirement, whether each display area can be overlapped or not can be set, and whether one display area of the independent device can be overlapped with other display areas or not can be set.
In addition, a set-top state of the first display area and the second display area when the first display area and the second display area overlap may also be set in the display device. For example, when the first display area is located above the second display area at this time, but when the content of the second display area needs to be displayed at this time, besides dragging the second display area to other non-occluded areas, the state device of the second display area may be set to the top, so that the content of the second display area is displayed in the screen of the display device without occlusion.
The method includes the steps that the proportional size of a first display area and the first screen throwing device is obtained according to the size of the first display area of the first screen throwing device in a display screen of the display device and the size of the first screen throwing device, and then a first screen throwing icon corresponding to the first screen throwing device in the first display area is determined according to the proportional size. According to the size of a second display area of the second screen-throwing device in a display screen of the display device and the size of the second screen-throwing device, the proportional size of the second display area and the second screen-throwing device is obtained, and then a second screen-throwing icon corresponding to the second screen-throwing device in the second display area is determined according to the proportional size.
For example, the size of the first display area divided by the display device is 120cm×90cm, the size of the interface of the first screen projection device is 40cm×30cm, the screen projection ratio of the interface of the first display area and the first screen projection device is 3, and then the corresponding first screen projection icon in the first display area is displayed according to 3 times of the size of the icon in the first screen projection device.
In some embodiments, after the display device establishes the screen-casting connection with the first screen-casting device and the second screen-casting device, the method further comprises: a protocol query request sent by the first screen throwing device is obtained, and a first transmission protocol corresponding to the display device is returned according to the protocol query request; receiving a first data transmission form of the first screen projection device determined with the display device according to the first transmission protocol; a protocol query request sent by the second screen throwing device is obtained, and a first transmission protocol corresponding to the display device is returned according to the protocol query request; receiving a second data transmission form determined by the second screen projection device according to the first transmission protocol and the display device; wherein the display device is capable of effecting a data transfer between the first data transmission form and the second data transmission form.
For example, after the display device and the first screen-throwing device and the second screen-throwing device establish the screen-throwing connection, in order to realize the subsequent data transmission between the first screen-throwing device and the second screen-throwing device, the data transmission form between the display device and the first screen-throwing device and the second screen-throwing device needs to be obtained respectively.
For example, after the first screen-throwing device and the display device establish screen-throwing connection, the first screen-throwing device sends a protocol query request to the display device, so as to obtain a first transmission protocol supported by the display device, and then combines the transmission protocol supported by the first screen-throwing device with the transmission protocol supported by the first screen-throwing device, so as to obtain an intersection of the transmission protocol supported by the first screen-throwing device and the first transmission protocol, so as to obtain a first data transmission form. After the second screen throwing device and the display device establish screen throwing connection, the second screen throwing device sends a protocol query request to the display device, so that a first transmission protocol supported by the display device is obtained, and then the transmission protocol supported by the second screen throwing device is combined with the transmission protocol supported by the second screen throwing device, so that an intersection is obtained between the transmission protocol supported by the second screen throwing device and the first transmission protocol, and a second data transmission form is obtained.
In addition, the first screen projection device and the second screen projection device may not be in the same local area network, and data transmission between the first screen projection device and the second screen projection device is achieved through the display device, so that the display device can achieve data conversion between the first data transmission form and the second data transmission form.
For example, the Miracast protocol specifies that the screen-throwing device and the display device perform RTSP (real-time streaming protocol) parameter negotiation after a p2p link is established, and the screen-throwing device sends a request to the display device to obtain RTSP capability supported by the display device; and the screen throwing equipment replies the self-supporting capacity to the display equipment, so that the data transmission form between the screen throwing equipment and the display equipment is determined.
For example, the transmission protocol supported in the screen throwing device is A, B, C, the transmission protocol supported in the display device is A, E, F, and then the screen throwing device sends a first transmission protocol for requesting to obtain the support of the display device to obtain the transmission protocol A, E, F, and further the screen throwing device obtains an intersection according to the transmission protocol A, B, C and the transmission protocol A, E, F supported by the screen throwing device, so that the data transmission form between the screen throwing device and the display device can be obtained as the transmission protocol a.
In some embodiments, the receiving the first data transmission form of the first screen-projecting device determined with the display device according to the first transmission protocol includes: acquiring a confirmation request sent by the first screen-throwing device, wherein the confirmation request is used for determining second transmission protocol capability commonly supported by the first screen-throwing device and the display device according to the first transmission protocol capability; determining whether the acknowledgement request is correct according to the second transmission protocol capability; and when the confirmation request is correct, determining that the second transmission protocol capability is a first data transmission form of the first screen projection device and the display device.
For example, after the first data transmission form of the display device is determined by the first screen-throwing device, the first screen-throwing device sends a confirmation request of the commonly supported second transmission protocol capability to the display device, the display device confirms whether the second transmission protocol capability is correct, if so, a reply requesting to be correct is sent to the first screen-throwing device, if not, a reply requesting to be incorrect is sent to the first screen-throwing device, and then the first screen-throwing device sends a protocol query request to the display device again.
For example, after the display device replies the RTST capability supported by the display device to the screen-throwing device, the screen-throwing device obtains the intersection of the received RTST capability of the display device and the RTST capability of the display device, and then obtains the second transmission protocol capability commonly supported by the screen-throwing device and the display device, and the screen-throwing device sends a confirmation request of the commonly supported second transmission protocol capability to the display device. When the request is confirmed to be correct, data transmission between the display device and the screen throwing device is realized through the second transmission protocol capability.
In addition, the display device can be connected with one screen throwing device only, but a group is established by the display device and the screen throwing device, wherein the display device is used as a group leader, the S display device is used as a group member, and then a natural local area network is established for the screen throwing device in such a group environment, so that the multimedia stream transmission of the multiple devices is performed, and the equipment in the local area network is worth noting that the equipment does not lose STA function, namely the display device or any screen throwing device can be normally connected with a wifi hotspot to surf the internet.
Step S2: and when a file selection instruction is received, determining a target file from files stored in the first screen projection equipment according to the file selection instruction.
By way of example, clicking the first screen-throwing icon in the first screen-throwing device in the first display area through the mouse, and determining the target file from the files stored in the first screen-throwing device through clicking the selected first screen-throwing icon.
Alternatively, the file selection instruction may be obtained by clicking a mouse, double clicking, right clicking, or the like, or by gesture touching, or the like, and the obtaining manner of the specific file selection instruction is not particularly limited.
In some embodiments, when receiving a file selection instruction, determining a target file from files stored in the first screen projection device according to the file selection instruction includes: acquiring a first mapping relation between a first screen-throwing icon corresponding to the first screen-throwing device and a first real icon corresponding to the first screen-throwing device; and determining a target file from files stored in the first screen projection device according to the file selection instruction and the first mapping relation.
When determining the size of the first screen throwing device in the first display area of the display screen of the display device, obtaining the proportion information between the size of the first display area and the interface size of the first screen throwing device, determining a first mapping relation between a first screen throwing icon corresponding to the first screen throwing device and a first real icon corresponding to the first screen throwing device according to the proportion information, and determining a target file of an icon selected from the first screen throwing icons in the first display area in the first screen throwing device according to the first mapping relation.
Similarly, when the size of the second display area of the second screen projection device on the display screen of the display device is determined, the proportion information between the size of the second display area and the interface size of the second screen projection device is obtained, and further, a second mapping relation between a second screen projection icon corresponding to the second screen projection device and a second real icon corresponding to the second screen projection device is determined according to the proportion information, and further, a target file of an icon selected by a file selection instruction in the second screen projection icon in the second screen projection device is determined according to the second mapping relation.
In addition, when the size of the first display area in the display screen of the display device is changed, the first mapping relationship between the first screen-throwing icon corresponding to the first screen-throwing device and the first real icon corresponding to the first screen-throwing device is also changed. Thus, the first mapping relation is closely related to the size of the first display area.
In some embodiments, the determining, according to the file selection instruction and the first mapping relationship, a target file from files stored in the first screen projection device includes: obtaining the position information of the file selection instruction in the first screen projection icon according to the file selection instruction; and determining a target file from files stored in the first screen projection equipment according to the position information and the first mapping relation.
The method includes the steps that position information of a first screen projection icon of a file selection instruction in a first display area is determined according to the file selection instruction, and then a target file in files stored by first screen projection equipment selected by the file selection instruction is determined according to the position information and a first mapping relation.
For example, as shown in fig. 4, a coordinate system is established on the display screen of the display device 10, first, coordinate information corresponding to the first display area is obtained, and the coordinate information is respectively a (10, 20), B (130, 20), C (10, 120), D (130, 120), if the icon P,201 corresponds to the file 1 in the first screen-projection icon corresponding to the first screen-projection device 20 at this time, the mapping relationship between the icon P,201 and the file 1 is A1 (40, 30), B1 (45, 30), C1 (40, 50), D1 (45, 50), and when the coordinate information corresponding to the file selection instruction is between A1 (40, 30), B1 (45, 30), C1 (40, 50), D1 (45, 50), the target file is the file 1 in the first screen-projection device.
In addition, after the file selection instruction is obtained, coordinate information of the file selection instruction on a display screen of the display device is obtained according to the file selection instruction, whether the coordinate information of the file selection instruction on the display screen of the display device is located in a first display area or not is firstly judged, namely, the coordinate information corresponding to the file selection instruction is located among A (10, 20), B (130, 20), C (10, 120) and D (130, 120), and further, a target file in files stored in a first screen throwing device corresponding to the file selection instruction is further judged according to the coordinate information corresponding to the file selection instruction and a first mapping relation.
Step S3: when a file transmission instruction of the target file is received, the target file is obtained from the first screen projection device according to the file transmission instruction, the target file is transmitted to the second screen projection device by taking the display device as a transfer point of the target file, wherein the file transmission instruction is generated after the target file is selected in the first display area and released in the second display area, and a first operation of the target file selected in the first display area and a second operation of the target file released in the second display area are adjacent operations.
The file transmission instruction is generated after the target file is selected in the first display area according to the file selection instruction and released in the second display area, and then the target file in the first screen projection device is transmitted to the second screen projection device through the display device as a middle point according to the file transmission instruction, wherein the first operation of the target file selected in the first display area and the second operation of the target file released in the second display area are adjacent operations.
For example, if the target file is selected by clicking the mouse in the first display area and then clicking the target file in the second display area, a file transmission instruction for transmitting the target file in the first screen projection device to the second screen projection device is generated.
Or selecting the target file in the first display area in an external touch screen mode, and keeping the touch state until the target file reaches a desired placement position in the second display area, and releasing the touch state after leaving the display screen, so as to generate a file transmission instruction for transmitting the target file in the first screen throwing device to the second screen throwing device. Wherein the external touch display screen can be realized by a finger or a capacitance pen.
The target file is obtained from the first screen throwing device according to the file transmission instruction, the target file is transmitted to the second screen throwing device by taking the display device as a transfer point of the target file, the target file in the first screen throwing device can be transmitted to the second screen throwing device from the display device after being completely transmitted to the display device, or the target file in the first screen throwing device can be transmitted to the display device from the target file in the first screen throwing device, and meanwhile, the target file is transmitted to the second screen throwing device from the display device.
For example, a group is established by a display device and a screen-casting device, wherein the display device acts as a group leader and the S display device acts as a group member, and such a group environment in turn establishes a natural local area network for the screen-casting device. However, the group members in the group do not know the information of each other substantially, but only the IP information of the group owner is known, only the group owner has the information list of all the screen throwing devices in the group, so that the communication among the group members without links is realized by the group owner, the first screen throwing device can be controlled by the display device to store the target file into the cache file A in the display device in combination with the file transmission instruction, and the display device further sends the cache file A to the second screen throwing device, thereby realizing file transmission.
In some embodiments, after the display device establishes the screen-casting connection with the first screen-casting device and the second screen-casting device, the method further comprises: obtaining a first data transmission address corresponding to the first screen-throwing device and a second data transmission address corresponding to the second screen-throwing device, and storing the first data transmission address and the second data transmission address. Acquiring the target file from the first screen projection device according to the first data transmission address, and caching the target file in the display device to acquire a cache file; and transmitting the cache file to the second screen projection device according to the second data transmission address.
The method includes the steps that after a screen is built between a display device and first screen throwing equipment and second screen throwing equipment, a first data transmission address corresponding to the first screen throwing equipment and a second data transmission address corresponding to the second screen throwing equipment are obtained, the first data transmission address and the second data transmission address are stored, after a file transmission instruction is received, a target file is obtained from the first screen throwing equipment according to the first data transmission address, and the target file is cached in the display device to obtain a cache file; and transmitting the buffer file to the second screen throwing device according to the second data transmission address.
In some embodiments, the target file is selected in the first display area and released in the second display area, including: and after the file icon corresponding to the target file in the first screen projection icon is selected by the target object in the first display area and the file icon is dragged to the second display area by the target object, if the target object is detected to execute the preset triggering operation on the file icon, the target file is released in the second display area.
In an exemplary embodiment, after a file icon corresponding to a target file in the first screen-throwing icon is selected by a target object in the first display area and the target object drags the file icon from the first display area to the second display area, if it is detected that the target object performs a preset triggering operation on the file icon, a file transmission instruction after the target object is released in the second display area is generated.
For example, when the target object adopted when the first screen-throwing icon is selected by clicking a mouse, dragging the file icon to the second display area through the mouse and executing a clicking release operation by the mouse, and generating a file transmission instruction after the target object is released in the second display area.
For example, when the target object adopted when the first screen-throwing icon is selected by clicking the mouse, the target object moves to the second display area, and the mouse performs clicking operation, so that the target file is released in the second display area.
Optionally, through a preset trigger condition, if the trigger condition of the target object on the file icon is detected, the target file is released in the second display area. For example, the target object performs a single click, double click, or the like on the file icon.
In some embodiments, the drag track of the target file is displayed on the display screen during the process of dragging the file icon to the second display area.
For example, the pattern of displaying the file icon logo may be followed in the target object in the first display area corresponding to the first screen device 10 to the second display area corresponding to the second screen device 20, so that the dragging track of the target file following the target object is displayed in the display screen, as shown in fig. 5.
In some embodiments, when the file icon is dragged to the second display area by the target object, file release prompt information is displayed in the second display area.
The file icon is dragged to the second display area by the target object, and file release prompt information is displayed in the second display area.
For example, when three screen throwing devices are included in the display device, such as a first screen throwing device, a second screen throwing device and a third screen throwing device, the target object drags a text icon in a first screen throwing icon of the first screen throwing device in a first display area to a second display area of the second screen throwing device in the display device, text release prompt information in the second screen throwing device is displayed in the display device, and then whether a user executes text release operation according to own needs or not is displayed, or the target object drags a text icon in the first screen throwing icon of the first screen throwing device in the first display area to a third display area of the third screen throwing device in the display device, text release prompt information in the third screen throwing device is displayed in the display device, and then whether the user executes text release operation according to own needs or not is displayed in the display device.
If the second display area of the second display device and the third display area of the third display device have overlapping parts, when the target object reaches the overlapping parts of the second display area and the third display area, the display device can obtain the file release prompt information, and when the file release operation is currently executed, the target file is transmitted to which screen throwing device.
In addition, when the target object drags the text icon in the first screen throwing icon of the first screen throwing device in the first display area to other positions of the first screen throwing device in the first display area of the display device, text release prompt information 'currently operated as data position moving operation inside the first screen throwing device' of the current text release prompt information in the first screen throwing device is displayed in the display device, and then the current operation of a user is prompted, and only the data position inside the first screen throwing device is moved.
In some embodiments, the file release prompt information is generated when the file icon is dragged by the target object to an area where the second screen projection icon is located in the second display area.
Illustratively, the file icon is generated when the target object drags the file icon from the first display area to the area where the second drop icon in the other display area is located.
For example, when the file icon is just dragged from the first display area to the second display area, a file release prompt is generated for reminding the user to reach the second screen device.
Or when the file icon reaches the upper surface of a certain second screen projection icon in the second display area, generating file release prompt information for reminding a user that the file content corresponding to the certain second screen projection icon in the second screen projection device is covered if the release operation is performed at the moment.
Or when the file icon is just dragged from the first display area to the second display area and reaches a certain folder, file release prompt information is generated, and the file release prompt information is used for reminding a user of not having the authority to operate the folder, and the like.
In some embodiments, the method further includes generating a drag failure prompt on the display screen if a drag failure occurs during the drag of the file icon by the target object to the second display area.
For example, if a drag failure prompt is generated on the display screen when a drag break or similar problem occurs in a process that the file icon is dragged to the second display area by the target object, the drag failure prompt is used for reminding a user that the generation of the file transmission instruction is broken at this time, and a re-operation is required.
For example, if the wireless mouse is operated on the display screen of the display device and the wireless mouse is disconnected in the process that the file icon is dragged to the second display area by the target object, a dragging fault prompt is generated on the display screen at the moment, so that a user is reminded that the generation of the file transmission instruction is disconnected at the moment and the user needs to operate again.
