Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Based on the above problems, embodiments of the present application provide a first screen sharing method, apparatus, storage medium, and terminal, which can improve screen sharing efficiency between terminals. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a screen sharing method according to an embodiment of the present disclosure. The screen sharing method can be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The specific flow of the screen sharing method can be as follows:
101. when a screen sharing instruction is detected, acquiring the current network transmission rate, wherein the screen sharing instruction indicates that the display screen of the sharing device is shared with the shared device.
In the embodiment of the application, the sharing device and the shared device may be terminals of the same type or terminals of different types. For example, the sharing device may be a mobile phone, the shared device may be a computer, and the sharing device and the shared device are different types of terminals. For another example, the sharing device may be a mobile phone, and the shared device may be a mobile phone, and then the sharing device and the shared device may be terminals of the same type.
The sharing device and the shared device share a screen, which may mean that the sharing device and the shared device perform screen sharing. Screen sharing is a technology for remotely viewing or controlling desktops of other terminal devices on the terminal devices. Screen sharing is also known as screen sharing, screen synchronization, or sharing on the same screen.
The scene of screen sharing is generally that multiple computers (or tablets and mobile phones) work in coordination. For example, when training is carried out in a conference room, a lecturer (or a lecturer) shares a computer picture of the lecturer with other people participating in the conference, so that the participants only need to watch screens of the lecturer; for example, a teacher gives a lesson in a classroom, and a student computer displays the contents of the teacher computer courseware in real time; for example, when a paperless conference is held, the participants hold computers, and the pictures and the screen of the speaker computer are synchronized. In general, screen sharing may be: the method comprises the steps of sharing a computer screen to a plurality of computers, sharing the computer screen to a tablet or a mobile phone, sharing a mobile phone screen to a computer, and sharing the mobile phone screen to the tablet or other mobile phones.
Wherein the screen sharing instruction may be triggered by a user. The sharing device receives a screen sharing instruction triggered by a user, selects a shared device, and is connected with the shared device, namely the sharing device and the shared device can share the screen. When the sharing device and the shared device share the screen, the current network transmission rate can be acquired. The network transmission rate may represent how fast the data transmission speed is, and may be in bps (bits per second). For example, the network transmission rate may be 150Mbps, etc.
102. And processing the current display interface according to the network transmission rate to obtain a processed display interface.
After the current network transmission rate is obtained, the current display interface can be processed according to the network transmission rate. The current display interface may be a display interface to be shared by the sharing device to the shared device currently. By processing the current display interface, a processed display interface can be obtained.
In some embodiments, the step of processing the current display interface according to the network transmission rate to obtain a processed display interface may include:
(1) when the network transmission rate is smaller than a preset network transmission rate, acquiring a multiplying power value between the network transmission rate and the preset network transmission rate;
(2) and intercepting the current display interface according to the multiplying power value to obtain the processed display interface.
In the related art, when screen sharing is performed between terminals, a higher network transmission speed is required to ensure the smoothness of screen sharing between terminals. However, when the network is affected by other factors, the network transmission speed is slowed down, thereby affecting the screen sharing display between terminals. Therefore, according to the scheme, the display interface to be shared of the sharing equipment can be processed when the low-speed network is in the low-speed network, image transmission data are reduced, the smoothness of screen sharing when the low-speed network is in the low-speed network is guaranteed, and user experience can be greatly improved.
After the current network transmission rate is obtained, the current network transmission rate may be compared with a preset network transmission rate. The preset network transmission rate may be the lowest network transmission rate that ensures smooth screen sharing between the sharing device and the shared device, and may also be set by a user through self-definition, and the like, which is not limited herein.
For example, the network transmission rate may be 25Mbps, the preset network transmission rate may be 50Mbps, and comparing the network transmission rate with the preset network transmission rate may determine that the network transmission rate is less than the preset network transmission rate. For another example, the network transmission rate may be 100Mbps, the preset network transmission rate may be 50Mbps, and comparing the network transmission rate with the preset network transmission rate may determine that the network transmission rate is greater than the preset network transmission rate.
If the network transmission rate is less than the preset network transmission rate, the multiplying factor value between the network transmission rate and the preset network transmission rate can be obtained, and the multiplying factor value represents the multiplying factor between the network transmission rate and the preset network transmission rate and can be obtained by calculating the network transmission rate and the preset network transmission rate.
For example, the network transmission rate may be 25Mbps, the preset network transmission rate may be 50Mbps, the network transmission rate value is 25, the preset network transmission rate value is 50, and a multiple value of 1/2, that is, a value indicating that the network transmission rate is 1/2 times of the preset network transmission rate, may be obtained through calculation.
If the network transmission rate is greater than the preset network transmission rate, the current network data transmission speed is high, the smoothness of screen sharing between the sharing equipment and the shared equipment can be ensured, and the current display interface does not need to be processed.
After determining the magnification value between the network transmission rate and the preset network transmission rate, the current display interface may be processed according to the magnification value to obtain a processed display interface.
In some embodiments, the intercepting the current display interface according to the magnification value may include:
(2.1) acquiring the size parameter of the current display interface;
(2.2) processing the multiplying power value and the size parameter to obtain a processed size parameter;
and (2.3) performing interception processing on the current display interface based on the processed size parameter.
The size parameter of the current display interface is also the resolution of the current display interface of the sharing device, and the display resolution (screen resolution) is the precision of the screen image, which means how many pixels can be displayed by the display. Since the dots, lines and planes on the screen are all composed of pixels, the more pixels the display can display, the finer the picture, and the more information can be displayed in the same screen area. For example, the screen resolution may be 100x100 pixels, and accordingly, the screen display size may be 100x 100.
After the size parameter of the current display interface is determined, the size parameter can be processed according to the magnification value, and the processed size parameter is obtained. Specifically, the processing may be performed according to a preset calculation formula, where the preset calculation formula may be: and (4) after treatment, the size parameter is the value x times of the size parameter.
For example, if the size parameter of the current display interface is 100x100 (i.e., representing width x height), the size parameter values are 100 and 100, and the magnification value may be 1/2, then processing is performed according to a preset calculation formula, and the processed parameter may be 50x 50.
After the processed size parameter is determined, the current display interface may perform the intercepting process according to the processed size parameter. The intercepting process may be to perform a cropping operation on the display interface image to obtain a part of the display interface.
In some embodiments, the step of performing, based on the processed size parameter, an interception process on the current display interface may include:
(2.31) acquiring the position of the central point of the current display interface;
(2.32) determining a clipping region in the current display interface based on the center point position and the processed size parameter;
(2.33) determining the processed display interface according to the intercepted area.
Wherein, the position of the central point can be determined by the size parameters of the current display interface, wherein the size parameters can comprise a wide value, a high value and the like. Specifically, a coordinate axis space may be constructed based on the current display interface, where the wide value is used as one coordinate axis and the high value is used as the other coordinate axis. For example, if the width value is 100 and the height value is 100, then a coordinate axis can be constructed based on the width value of 100 and the height value of 100, and then the center point position can be determined to be (50, 50)
After the position of the center point of the current display interface is determined, the intercepting area can be determined in the current display interface according to the processed size parameters obtained in the above steps. The position of the central point of the intercepted area may be the same as the position of the central point of the current display interface, and the size of the intercepted area may be a processed size parameter, so as to determine the intercepted area. The cutting-out area is cut out from the current display interface, and the cutting-out area can be used as a processed display interface.
In some embodiments, the step of performing, based on the processed size parameter, an interception process on the current display interface may include:
(2.34) performing content identification on the current display interface;
(2.35) determining a cutting area from the current display interface according to the content identification result;
(2.36) determining the processed display interface according to the intercepted area.
The content identification may refer to identifying all display contents of the current display interface, and the display contents of the same display type may be divided into one display area. The display types may include various types, such as text display, picture display, background display, pattern display, and the like.
Referring to fig. 2, fig. 2 is a schematic view illustrating a display interface processing according to an embodiment of the present disclosure. After the content recognition operation is performed on the current display interface, the first display area, the second display area, the third display area and the fourth display area shown in fig. 2 can be obtained. The display type of the first display area may be text display, the display type of the second display area may be picture display, the display type of the third display area may be background display, and the display type of the fourth display area may be pattern display.
After the display type of each display region is determined, a target display region may be determined as a cut-out region from the plurality of display regions according to the importance level of the display type. The importance level of the display type may be preset, for example, the text display may be set as a first level, the picture display may be set as a second level, the background display may be set as a third level, and the pattern display may be set as a fourth level, where the importance level of each level may be the first level, the second level, the third level, and the fourth level in sequence from high to low.
Further, in fig. 2, it may be determined that the importance degree of the first display area is the highest, the size of the first display area may be compared with the processed size parameter, and if the size of the first display area is greater than the processed size parameter, the first display area may be cut accordingly, where the cutting manner may include multiple types, for example, cutting according to the central point of the first display area as a midpoint, and the like. The target area, i.e. the cut-out area, may be determined based on the first display area, thereby determining the processed display interface.
In some embodiments, the intercepting the current display interface according to the magnification value to obtain a processed display interface may include:
adjusting the current display interface based on the multiplying power value to obtain an adjusted display interface;
dividing the adjusted display interface into a plurality of display sub-areas;
acquiring a corresponding display area of each display sub-area in the current display interface and the difference between the display area and the corresponding display area;
and determining a display sub-area with the largest difference with the corresponding display area in the current display interface from the adjusted display interface as the processed display interface.
The adjustment of the current display interface based on the magnification value may be to perform amplification processing on the current display interface. Specifically, the size parameter of the current display interface may be processed according to the magnification value, so that the processed display interface may be obtained. For example, the magnification value may be 1/2, and the size parameter of the current display interface may be 100x100, then the size parameter and the magnification value are calculated, and the size parameter of the processed display interface may be determined to be 200x200, so as to obtain the adjusted display interface.
After the adjusted display interface is determined, the adjusted display interface may be divided into a plurality of display sub-regions, where the dividing manner may include various manners, for example, the display sub-regions may be divided according to the area of the adjusted display interface on average, the adjusted display interface may be divided into a plurality of display sub-regions with the same area on average, and the like. Correspondingly, after the adjusted interface is divided into a plurality of display sub-regions, the current display interface may be divided into a plurality of display sub-regions in the same manner as described above, where each sub-region in the current display interface may correspond to each display sub-region in the adjusted display interface one to one.
In some embodiments, please refer to fig. 3, where fig. 3 is a schematic view of another display interface processing provided in the embodiments of the present application. Fig. 3 shows a display interface and a processed display interface, where the display interface may be a current display interface, and the processed display interface may be a display interface obtained by performing amplification processing on the current display interface according to a magnification value. Because the processed display interface is an enlarged interface of the display interface, the display content of the display interface corresponds to the content of the processed display interface one to one. For example, in fig. 3, the display interface may include a first area, a second area, a third area and a fourth area, and the processed display interface may include a fifth area, a sixth area, a seventh area and an eighth area, so that according to the display position of each area in different display interfaces, it may be determined that the first area corresponds to the fifth area, the second area corresponds to the sixth area, the third area corresponds to the seventh area, and the fourth area corresponds to the eighth area.
After determining the corresponding relationship between each display sub-region in the current display interface and each display sub-region in the adjusted display interface, the corresponding display sub-regions may be compared, for example, the first region may be compared with the fifth region, the second region may be compared with the sixth region, the third region may be compared with the seventh region, and the fourth region may be compared with the eighth region, so that the difference between the corresponding display sub-regions may be obtained. Wherein, the content definition, color and the like between the display sub-regions can be compared to judge the difference.
For example, in fig. 3, comparing the first region with the fifth region, comparing the second region with the sixth region, comparing the third region with the seventh region, and comparing the fourth region with the eighth region, the similarity between the first region and the fifth region may be 50%, the similarity between the second region and the sixth region may be 30%, the similarity between the third region and the seventh region may be 80%, and the similarity between the fourth region and the eighth region may be 70%, then it may be determined that the difference between the second region and the sixth region is the largest, and then the second region in the display interface may be determined as the processed display interface.
In some embodiments, before sending the processed display interface to the shared device, the method may further include:
when an adjusting instruction is received, adjusting the current display interface according to the adjusting instruction to obtain an adjusted display interface;
determining the processed display interface based on the adjusted display interface.
The adjusting instruction can be an adjusting instruction triggered by a user, the adjusting instruction is triggered by touch operation of the user on the current display interface, the adjusting instruction can be intercepting operation on the current display interface, a part of display area is intercepted from the current display interface according to the user operation, and the intercepted display area is used as a processed display interface. The user can select the display area to share by himself by adjusting the operation of the instruction on the current display interface.
103. And sending the processed display interface to the shared device, so that the processed display interface is synchronously displayed on the shared device.
After determining the processed display interface, the processed display interface may be sent to the shared device. The transmission data volume of the processed display interface is reduced relative to the transmission data volume of the current display interface, so that the screen sharing between the sharing equipment and the shared equipment can be continued at a low network transmission rate.
After the shared device receives the processed display interface sent by the sharing device, the processed display interface may be processed, for example, resolution may be adjusted, so that the processed display interface may be clearly displayed on the display screen of the shared device.
The embodiment of the application discloses a screen sharing method, which comprises the following steps: when a screen sharing instruction is detected, acquiring the current network transmission rate, wherein the screen sharing instruction indicates that a display screen of the sharing device is shared with a shared device; processing the current display interface according to the network transmission rate to obtain a processed display interface; and sending the processed display interface to the shared device, so that the processed display interface is synchronously displayed on the shared device. According to the method and the device, the network transmission rate of the sending terminal in the screen sharing process is detected, the current display interface is cut according to the network transmission rate to obtain the target display interface, the target display interface is transmitted to the receiving terminal to be displayed, transmitted image data can be reduced when the network transmission rate is low, the smoothness of screen sharing is guaranteed, and the screen sharing efficiency between the terminals can be improved.
Referring to fig. 4, fig. 4 is a schematic flowchart of another screen sharing method according to an embodiment of the present disclosure. In the embodiment of the present application, screen sharing between a sending terminal and a receiving terminal is taken as an example for description, and specific scene applications of the screen sharing method may be as follows:
201. and the sending terminal receives a screen sharing instruction triggered by a user and performs screen sharing with the receiving terminal according to the screen sharing instruction.
In the embodiment of the present application, the sending terminal may be a mobile phone, the receiving terminal may be a computer, and the present application is specifically described by taking a screen sharing operation between the mobile phone and the computer as an example.
The sending terminal can be in network connection with the receiving terminal, and can start sharing with the receiving terminal after receiving a screen sharing instruction triggered by a user. The screen sharing instruction can be used for screen sharing between the sending terminal and the receiving terminal.
202. And in the process of sharing the screen between the sending terminal and the receiving terminal, acquiring the current network transmission rate.
After the sending terminal and the receiving terminal perform screen sharing, the current network transmission rate can be acquired in the screen sharing process. Since the sending terminal and the receiving terminal perform screen sharing through network connection, a higher network transmission rate is required in the screen sharing process of the sending terminal and the receiving terminal. According to the method and the device, when the network transmission rate is low, the shared display interface of the sending terminal is processed, so that the smoothness of screen sharing is guaranteed.
The current network transmission rate may be a network transmission speed at which the current sending terminal transmits the shared interface to the receiving terminal. For example, the current network transmission speed may be 10 Mbps.
203. The sending terminal judges whether the network transmission rate is less than a preset network transmission rate.
After determining the current network transmission rate, the sending terminal may determine whether the network transmission rate is less than a preset network transmission rate. The preset network transmission rate may be a network transmission rate that is the minimum requirement for screen sharing between the sending terminal and the receiving terminal, and when the network transmission rate is less than the preset network transmission rate, screen sharing between the sending terminal and the receiving terminal may be affected.
For example, the obtained network transmission rate may be 10Mbps, and the preset network transmission rate may be 50Mbps, then it may be determined that the network transmission rate is less than the preset network transmission rate, and step 204 may be executed.
For another example, if the obtained network transmission rate may be 100Mbps and the preset network transmission rate may be 50Mbps, it may be determined that the network transmission rate is less than the preset network transmission rate, and step 208 may be executed.
204. The sending terminal obtains a multiplying factor value between the network transmission rate and a preset network transmission rate.
When the network transmission rate is less than the preset network transmission rate, a magnification value between the network transmission rate and the preset network transmission rate may be obtained, where the definition of the magnification value may refer to the foregoing embodiment, which is not described herein in detail.
For example, the network transmission rate may be 10Mbps, the preset network transmission rate may be 50Mbps, and it may be determined that the multiplication factor value between the network transmission rate and the preset network transmission rate may be 1/5.
205. And the sending terminal determines the size parameter based on the current display interface and the magnification value.
The size parameter is determined based on the current display interface and the magnification value, and the size parameter of the current display interface may be processed according to the magnification value to obtain a processed size parameter, that is, the size parameter.
For example, if the size parameter of the current display interface may be 100x100 and the magnification value may be 1/5, the size parameter and the magnification value of the current display interface are processed, and the processed size parameter may be 20x 20.
206. And the sending terminal intercepts a display area corresponding to the size parameter on the current display interface as a target display interface.

The display interface shown in fig. 5 may be a current display interface, and the position of the center point of the current display interface may be determined by a size parameter of the current display interface.

And determining the processed size parameter according to the size parameter and the magnification value of the current display interface, and determining the intercepting area from the current display interface according to the processed size parameter. In fig. 6, the display interface may be the current display interface, the center point of the current display interface is determined, the processed size parameter is determined according to the size parameter and the magnification value of the current display interface, and then the capture area, that is, the capture area shown in fig. 6, may be determined according to the center point and the processed size parameter, and the center point of the capture area and the center point of the display interface are located at the same position.
