Background
With the diversification and popularization of various intelligent terminals, especially the wide use of smart phones, tablet computers and smart televisions, and the development of high-speed Wifi related technologies, the real-time screen sharing with high image quality among the smart phones, the tablet computers and the televisions is more and more mature. The screen sharing and interaction means that sharing and interaction of screens and media content information among devices are realized based on various types of terminals, such as devices with screen display functions, such as smart phones, tablet computers, smart televisions, so as to meet the requirements of users on conveniently browsing webpages, playing, watching media, operating terminals and the like on different types of terminals.
However, when screen sharing is performed, the sizes of the screens of the transmitting end and the receiving end are not completely the same, and after the content displayed by the transmitting end is transmitted to the receiving end, the phenomenon of stretching deformation is likely to occur. When the number of terminals participating in sharing is large, the screen sharing experience is affected. Moreover, when data transmission is performed, especially when picture transmission is involved, a large memory is usually occupied, and thus the data transmission speed is reduced. Therefore, it is desirable to provide a more versatile and traffic-efficient screen sharing technique.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
FIG. 1 shows a schematic diagram of a data sharing system 100 according to one embodiment of the invention. As shown, the system 100 includes a data transmitting device 200 and a data receiving device 300 (e.g., the data receiving devices 1-4 in fig. 1), wherein the data transmitting device 200 and the data receiving device 300 perform data transmission via a data network.
The data transmission apparatus 200 and the data reception apparatus 300 may be implemented as a server, such as a file server, a data storage server, an application server, a WEB server, and the like, may be implemented as a personal computer including desktop and notebook computer configurations, and may be implemented as a part of a small-sized portable (or mobile) electronic apparatus, such as a mobile phone, a tablet computer, a personal media player apparatus, a wireless network browsing apparatus, a wearable apparatus (e.g., a smart watch, smart glasses, and the like), an application-specific apparatus, or a hybrid apparatus that may include any of the above functions. The data receiving device 300 includes one or more mobile devices, which may be internet-accessible devices such as cell phones, tablets, laptops, television boxes, wearable devices, and the like.
It should be noted that the data sharing system 100 in fig. 1 is only exemplary, in a specific practical situation, there may be different numbers of data sending devices 200 and data receiving devices 300 in the system 100, and the present invention does not limit the number of data sending devices and data receiving devices included in the data sharing system 100.
In the present invention, one device in the data sharing system may be designated as a master device, or one device may be designated as a master device in addition, and a reference screen may be set on the master device, for example, the reference screen may be the entire physical screen of the master device, or may be a part of the physical screen. And then, the main equipment broadcasts the width and height information of the reference screen to other equipment, the other equipment respectively creates a shared screen with the same width and height ratio as the reference screen after receiving the information, and calculates and stores the scaling ratio of the size of the shared screen to the size of the reference screen. Thus, each device in the data sharing system 10 of the present invention will have a zoom ratio of the shared screen on that device to the reference screen, where the main device may be considered to have a zoom ratio of 1 although the shared screen is not specifically created in the main device. After the shared screen between the terminals is created and the scaling ratio is assigned, the master device and the slave device are not technically distinguished, and any one device can be used as a data sending device to send data and can also be used as a data receiving device to receive data.
According to one embodiment, the data sharing system 100 may further include a picture server (not shown in the figure), which may be a single server or a server cluster composed of a plurality of servers. When the terminal needs to send the picture, the sending end firstly uploads the picture to the picture server to obtain the network address of the picture returned by the picture server, and the network address is sent to the receiving end. The receiving end can access the picture server according to the network address and obtain the picture content corresponding to the network address.
Fig. 2 is a block diagram of the structure of a data transmitting apparatus 200 and a data receiving apparatus 300 according to an embodiment of the present invention. For convenience of description, the shared screen in the data transmission apparatus 200 is referred to as a first shared screen, and the zoom ratio stored in the apparatus is referred to as a first zoom ratio; the shared screen in the data receiving apparatus 300 is referred to as a second shared screen, and the zoom ratio stored in the apparatus is referred to as a second zoom ratio.
As shown in fig. 2, the data transmission device 200 includes an information acquisition unit 220, a primary correction unit 240, and a data transmission unit 260.
The information obtaining unit 220 may obtain, in the first sharing screen, sharing information that needs to be transmitted according to a type of data to be shared, where the sharing information includes a location parameter that needs to be corrected and other information that does not need to be corrected.
The types of data that can be shared between devices include pictures, text, handwriting, screen operations, and the like.
According to one embodiment, when the data type to be shared is a picture, the sharing information that the information obtaining unit 220 needs to obtain includes vertex abscissa, vertex ordinate, width, height, picture content, and rotation angle of the picture. The position parameters to be corrected comprise a vertex abscissa, a vertex ordinate, and a width and a height of the picture.
Here, the picture content may be represented by a network address of the picture, and the information obtaining unit 220 is adapted to obtain the network address of the picture according to the following method: uploading the picture to be shared to a picture server, and acquiring the network address of the picture returned by the picture server.
According to another embodiment, when the type of data to be shared is a text, the shared information that the information obtaining unit 220 needs to obtain includes a vertex abscissa, a vertex ordinate, a width, a height, a font size, a text content, and a text color of a text box in which the text is located. The position parameters to be corrected include the vertex abscissa, vertex ordinate, font size, and width and height of the text box.
According to another embodiment, when the data type to be shared is a line (i.e. handwriting), the data sending device 200 may store the points drawn by the mouse or other input device on the terminal screen into an array, where each point includes an abscissa and an ordinate. Drawing the points in a Bezier curve mode can draw a smooth line. For such shared content of a line shape, the shared information that the information acquiring unit 220 needs to acquire includes an abscissa, an ordinate, a line width, and a line color of each point in the line. The position parameters to be corrected include the width of the line, and the abscissa and ordinate of each point in the line.
According to still another embodiment, when the type of data to be shared is a screen operation (e.g., screen clearing, page turning, etc.) implemented by clicking a button, the shared information that the information obtaining unit 220 needs to obtain includes a vertex abscissa, a vertex ordinate, a width, a height, and a button instruction of the button. The position parameters to be corrected include the vertex abscissa and vertex ordinate of the button, and the width and height, among others. Of course, in actual operation, the screen operation may also be implemented not by a button, but directly by an instruction, and in this case, the information obtaining unit 220 only needs to obtain the button instruction.
The primary correction unit 240 may correct the position parameters that need to be corrected according to the first scaling ratio. This correction of the location parameter may be referred to as an initial correction, and specifically, the location parameter may be divided by the first scaling ratio of the data transmission apparatus 200 to perform the correction. For example, if the width of the shared screen of the data transmission device 200 is 40cm and the first scaling ratio is 0.8, the width is initially corrected to 50 cm. Of course, the division method is only an exemplary illustration, and the correction can also be performed by using a mathematical operation method, which is not limited by the present invention.
The data transmitting unit 260 may transmit the corrected location parameters to the data receiving side via the network together with other information (e.g., text content, line color, etc.) that does not need to be corrected, respectively.
According to one embodiment, when screen sharing for a screen-clearing operation is performed, the initiator transmits a packet (JSON format) in the following format
And after receiving the data packet, the receiver clears all the drawing contents on the UI.
According to one embodiment, the data transmission device 200 may further include a data reception unit, a secondary correction unit, and a content presentation unit. The data receiving unit may receive the corrected location parameters and the other information corresponding to different data types sent by the data sending device via the network. The secondary correction unit may perform secondary correction on the received position parameter according to the first scaling ratio. The content presentation unit may present the content to be shared on the second sharing screen based on the secondarily corrected position parameter and the received other information.
As mentioned above, each device can be used as both a sender and a receiver to send and receive data, and when it is used as a receiver, it can include the above-mentioned three data receiving units, secondary correction unit and content presentation unit to implement its data receiving function. Of course, these three units may be provided in the data receiving apparatus 300 corresponding to the data transmitting apparatus 200 to constitute a complete content sharing system.
After the data transmission unit 260 transmits the data, the data reception device 300 receives the shared information transmitted by the transmitting party. As shown in fig. 2, the data receiving apparatus 300 includes: a data receiving unit 320, a secondary correction unit 340, and a content presentation unit 360.
The data receiving unit 320 may receive, via the network, shared information corresponding to different data types sent by the data sending apparatus, where the shared information includes location parameters (such as vertex coordinates, width, height, etc.) subjected to initial correction and other information (such as text content, etc.) that does not need to be corrected.
According to one embodiment, when the data type to be shared is a picture, the sharing information received by the data receiving unit 320 includes vertex abscissa, vertex ordinate, width, height, network address of the picture, and rotation angle of the picture. The position parameters subjected to primary correction comprise a vertex abscissa, a vertex ordinate, and width and height of the picture.
In addition, the data receiving device 300 may further include a picture obtaining unit (not shown in the figure), which may access the picture server according to the network address of the received picture, and obtain the picture content corresponding to the network address from the picture server.
According to another embodiment, when the type of data to be shared is a text, the sharing information received by the data receiving unit 320 includes vertex abscissa, vertex ordinate, width, height, font size, text content, and text color of a text box in which the text is located. The position parameters subjected to primary correction comprise vertex abscissa, vertex ordinate, font size, width and height of the text box.
According to still another embodiment, when the type of data to be shared is a line, the sharing information received by the data receiving unit 320 includes an abscissa, an ordinate, a line width, and a line color of each point in the line. The position parameters subjected to primary correction comprise the width of the line, and the abscissa and the ordinate of each point in the line.
According to still another embodiment, when the type of data to be shared is a screen operation by clicking a button, the sharing information received by the data receiving unit 320 includes a vertex abscissa, a vertex ordinate, a width, a height, and a button instruction of the button. Wherein the primarily corrected position parameters include a vertex abscissa, a vertex ordinate, and a width and a height of the button.
The secondary correction unit 340 may perform secondary correction on the received primarily corrected location parameter according to the second scaling ratio.
Here, the secondary correction of the position parameter may be multiplying the primarily corrected position parameter by the second scaling ratio of the data reception apparatus 300. For example, if the second scaling ratio of the data receiving apparatus 300 is 0.6 and the width after the primary correction is 50cm in the above example, the width is corrected twice to be 30 cm. Of course, the manner of multiplication is only an exemplary illustration, and it can also be corrected by using a mathematical operation method, and the present invention is not limited thereto.
The content presenting unit 360 may present the content to be shared on the second sharing screen based on the secondarily corrected location parameter and the received other information that does not need to be corrected, so that the same screen effect as that of the sender can be presented.
For example, when the content to be shared is a picture, the content presentation unit 360 presents the picture at a specified rotation angle at a specified position in the second sharing screen according to the acquired picture content and the vertex horizontal and vertical coordinates, width, and height of the picture frame after the secondary correction.
Or, when the content to be shared is a text, the content presenting unit 360 draws the text content of the corresponding text color and the corresponding text font size at the corresponding position of the second sharing screen according to the vertex horizontal and vertical coordinates, the width and the height of the text box after the secondary correction.
For another example, when the content to be shared is a line (handwriting), the content presenting unit 360 uses a bezier curve (also called a bezier curve or a bezier curve) to connect each point in the line to draw the handwriting at the corresponding position of the second shared screen according to the abscissa and the ordinate of the point and the line width of the point in the line after the second correction. Wherein, Bezier curve is the mathematical curve that is applied to two-dimensional graph application program, and the definition of curve has four points: a starting point, an end point (also called anchor point) and two mutually separated intermediate points; sliding the two intermediate points, the shape of the bezier curve changes. Of course, the bezier curve is only an exemplary illustration, and other curve plotting methods may be used, and the present invention is not limited thereto.
Finally, when the content to be shared is screen operations such as screen clearing and page turning implemented by the button, the content presenting unit 360 displays the button at the corresponding position of the second shared screen according to the secondary corrected horizontal and vertical coordinates and width and height of the button, and implements the corresponding screen operations according to the instruction of the button.
In addition, the data receiving apparatus 300 may also include an information acquisition unit, a primary correction unit, and a data transmission unit, as in the same principle of the arrangement of the data transmitting apparatus 200. The execution logic of each unit corresponds to and is the same as the three units in the data sending device 200 described above, and for details, reference may be made to the description of the three units in the data sending device 200, and details are not described here again.
The core code of the invention (the received data packet is analyzed and drawn) is as follows:

According to the technical scheme of the invention, each terminal device processes the picture of the terminal according to the zoom ratio of the terminal, and each terminal plays its own role and keeps the consistency of data processing. Therefore, no matter how many terminal devices exist in the whole system, no matter which device is used as a sender and which device is used as a receiver, as long as each terminal finishes the content processing work in the terminal, the consistency of content sharing can be ensured, and the problem of stretching deformation of content sharing is effectively solved.

Subsequently, in step S460, the corrected location parameter is transmitted to the second network device together with other information that does not need to be corrected.
