The first electronic equipment and the second electronic equipment can cooperate with each other in a mode of connecting the switching equipment in a wired mode, the cooperation of the equipment is realized based on hardware, data transmission is not needed to be carried out by a third party network, and the safety and stability of the cooperation of the equipment are improved.

In one possible example, the switching device further includes a first data conversion chip and a second data conversion chip; in the aspect of sending the first screen projection data to the first electronic device through the first interface, the control chip is specifically configured to: converting, by the first data conversion chip, the first screen-shot data in a first format that is matched with the second interface into the first screen-shot data in a second format, transmitting, by the first data conversion chip, the first screen-shot data in the second format to the second data conversion chip, converting, by the second data conversion chip, the first screen-shot data in the second format into the first screen-shot data in a third format that is matched with the first interface, and transmitting, by the first interface, the first screen-shot data in the third format to the first electronic device; wherein the second format is an audio/video format.

Wherein the first format matched with the first interface, i.e. the data in the first format matches the data transmission protocol of the first interface. Taking the first interface as a USB interface as an example, the data in the first format may be USB format data.

The first format and the third format may be determined according to data transmission protocols of the second interface and the first interface, respectively, and the first format and the third format may be the same or different.

For example, taking the second format as the HDMI format, the first interface and the second interface are both USB interfaces, and the first format and the third format are both USB formats, the switching device receives the first screen projection data in the USB format from the second interface, processes the first screen projection data in the HDMI format through the first data conversion chip, and the first screen projection data in the USB format can be output through the second data conversion chip and sent to the first electronic device through the first interface, and the first electronic device can receive and analyze the first screen projection data in the USB format for display.

In a specific implementation, the first data conversion chip can be a chip capable of converting data in a first format into data in a second format and converting the data in the second format into data in the first format, and correspondingly, the second data conversion chip can also be a chip capable of converting the data in the second format into data in a third format and converting the data in the third format into data in the second format, and a user can send information to the switching device through the first electronic device or the second electronic device, so that a control chip of the switching device can determine the transmission direction of screen-throwing data between the first electronic device and the second electronic device through the information, and then the control chip can adjust the working state of the data conversion chip, and can support bidirectional screen throwing of the first electronic device and the second electronic device, and the device is more convenient to cooperate.

In this example, the first data conversion chip and the second data conversion chip may be used to convert the format of the screen projection data, which is beneficial to improving the accuracy and efficiency of the transmission and processing of the screen projection data between the first electronic device and the second electronic device.

Referring to fig. 3, fig. 3 is a flowchart of a data processing method according to an embodiment of the present application. The data processing method can be applied to the switching device 100 shown in fig. 1 or fig. 2, the switching device includes a first interface and a second interface, the switching device is connected with the first electronic device through the first interface in a wired manner, and is connected with the second electronic device through the second interface in a wired manner, as shown in fig. 3, the data processing method includes the following steps:

step 201, when receiving the target operation event information from the first electronic device through the first interface, acquiring the latest updated real-time application function identifier of the local terminal.

The target operation event information is generated by the first electronic device in response to operation information of a user for screen projection content of the second electronic device displayed in a display interface of the first electronic device, and a real-time application function identifier of the local end of the switching device is updated according to the application function identifier from the second electronic device.

In a specific implementation, the manner of the second electronic device projecting the screen onto the first electronic device may include a mirror mode projecting screen and a computer mode projecting screen. When the mirror image mode is adopted for screen projection, screen display content of the second electronic equipment is subjected to screen capture or screen recording in real time, screen capture or screen recording data are sent to the switching equipment, the switching equipment forwards the screen capture or screen recording data to the first electronic equipment for display, and at the moment, a screen projection picture displayed by the first electronic equipment is completely consistent with a screen picture of the second electronic equipment.

When the screen is projected in the computer mode, the screen projected picture displayed by the first electronic device and the original screen picture of the second electronic device are not necessarily identical, if the second electronic device is using a certain application or function when being connected with the switching device, the second electronic device can directly send the screen content of the second electronic device to the switching device, namely, the current screen display content of the second electronic device is subjected to format conversion according to the display standard of the computer mode to generate screen projected data, and the screen projected data and the application function identifier of the application or function currently being used are sent to the switching device together, so that the switching device can send the screen projected data to the first electronic device for display, and the received application function identifier can be cached at the local end of the switching device.

If the display content of the second electronic device is a desktop when the second electronic device is connected with the switching device, the second electronic device can generate screen projection data according to the desktop display standard of the computer mode and send the screen projection data to the converter according to the application icon and the function control which are required to be displayed on the first electronic device side by the local end, and the converter sends the screen projection data to the first electronic device for display, so that the desktop arrangement form of the second electronic device displayed by the first electronic device is possibly different from the original arrangement form of the second electronic device. When the screen throwing content is a desktop, the display size of the screen throwing content of the second electronic device in the first electronic device can be set according to needs, for example, the display size of a screen throwing picture in a computer mode can be preset at the second electronic device end, and screen throwing data can be directly generated according to the preset display size, or the second electronic device can determine the display size of the screen throwing picture according to the screen size of the first electronic device, and further the screen throwing data can be generated, so that the screen throwing content of the desktop of the second electronic device can be displayed on the first electronic device side in a full screen mode.

Specifically, the second electronic device may send the screen throwing data to the conversion device, and simultaneously, may synchronize the display position coordinates of each application icon or function control in the screen throwing data to the converter, for example, send the corresponding relationship between each application icon or function control and the display position coordinates to the switching device, when a user operates and selects the application icon or function control on the desktop of the second electronic device displayed in the first electronic device at the first electronic device side, the first electronic device may send an operation event to the switching device, the switching device determines the selected application icon or function identifier according to the display position coordinates corresponding to the operation event, and then the switching device may determine the application function identifier of the application or function to be started, so that a start instruction carrying the application function identifier may be sent to the second electronic device, the second electronic device side may start the corresponding application or function, and generate new screen throwing data from the picture to be displayed on the screen throwing after the start, and send the new screen throwing data to the first electronic device for display. In addition, when the switching device sends a starting instruction carrying the application function identifier to the second electronic device, the real-time application function identifier cached at the local end can be updated to the application function identifier.

Step 202, inquiring a preset instruction set according to the latest updated real-time application function identifier to obtain a target instruction subset corresponding to the latest updated real-time application function identifier.

The instruction set comprises a plurality of application function identifications and a plurality of instruction subsets, wherein each instruction subset in the plurality of instruction subsets comprises a mapping relation between an operation event of the first electronic device and a control instruction of the second electronic device.

In a specific implementation, different instruction subsets in the instruction set respectively correspond to different application function identifiers, the same operation event may exist in different instruction subsets, but control instructions corresponding to the same operation event may exist in different instruction subsets.

And step 203, inquiring the target instruction subset according to the target operation event information to acquire a target control instruction corresponding to the target operation event.

And step 204, sending the target control instruction to the second electronic equipment through the second interface.

Wherein the target control instruction is used for giving an instruction for executing a target operation.

In the specific implementation, the real-time application function identifier cached in the switching device is updated in real time according to the application function identifier of the application or function of the screen of the second electronic device to the first electronic device, so that when the switching device receives the target operation event from the first electronic device, the switching device can always accurately determine the target control instruction corresponding to the target operation event in the current screen-throwing application or function, and therefore the correct target control instruction can be sent to the second electronic device.

Step 205, receiving first screen-projection data from the second electronic device through the second interface.

The first screen projection data are generated after the second electronic equipment executes the target operation.

And step 206, sending the first screen projection data to the first electronic equipment through the first interface.

The first screen projection data are used for giving an indication for content display according to the first screen projection data.

In step 205 and step 206, based on the data formats matched by the first interface and the second interface, the data format of the first screen projection data received by the switching device is matched with the second interface, the data format of the first screen projection data sent by the switching device is matched with the first interface, and the switching device can convert the data format of the first screen projection data through the data conversion chip, which can be specifically referred to the description about the structural composition and the device function of the switching device in the foregoing embodiment. It can be understood that, in the foregoing embodiments, the description about the switching device may be cited in the embodiment of the present method, and the steps executed by the switching device in the data processing method may be executed by the control chip in the switching device, which is not described herein again.

In one possible example, before the target operation event information from the first electronic device is received through the first interface and the latest updated real-time application function identifier stored by the local end is obtained, the method further includes: receiving second screen projection data carrying a target application identifier from the second electronic equipment through the second interface; transmitting the second screen throwing data to the first electronic equipment through the first interface, wherein the second screen throwing data are used for giving an instruction for displaying screen throwing content according to the second screen throwing data; and updating the real-time application function identifier of the local end of the switching equipment into the target application identifier.

In a specific implementation, when the second electronic device needs to throw a screen, the second electronic device can throw the screen to screen content displayed by the first electronic device according to the need to generate second screen throwing data, and the second screen throwing data and a target application function identifier corresponding to the screen content which needs to throw the screen to the first electronic device for display are sent to the switching device together, the switching device can forward the second screen throwing data, update the real-time application function identifier cached at the local end according to the target application function identifier, and when the first electronic device feeds back an operation event, the switching device can determine an instruction subset according to the latest updated real-time application function identifier at the local end, and further determine a control instruction corresponding to the operation event under the current screen throwing application, so that a correct control instruction can be fed back to the second electronic device.

In this example, the real-time application function identifier of the local end of the switching device is updated according to the application function identifier sent by the second electronic device, which is beneficial to improving accuracy of the target control instruction sent to the second electronic device when the switching device receives the target operation event of the first electronic device.

In one possible example, the target operation event includes a double-click target picture event, and a target control instruction corresponding to the double-click target picture event in the target instruction subset is used for giving an instruction of amplifying a target picture; the sending the target control instruction to the second electronic device includes: determining a target magnification scaling factor required by the first electronic device to display the target picture; and sending the target control instruction carrying the target amplification scale factor to the second electronic equipment.

In the specific implementation, since the first electronic device and the second electronic device are connected through the switching device, if the first electronic device and the second electronic device are directly communicated with each other to determine a proper picture amplification ratio, a determination flow of the picture amplification ratio is relatively complicated and takes longer time, meanwhile, the data processing pressure of the first electronic device and the second electronic device is increased, the switching device is used as an intermediate device of the first electronic device and the second electronic device, and after a target operation event of the first electronic device is received and a target control instruction to be sent to the second electronic device is determined, a required target amplification ratio coefficient is directly determined, so that the efficiency can be improved to a certain extent.

In this example, when the target operation event is a double-click target picture event and the target control instruction is used to give an instruction for amplifying the target picture, it is determined that the target amplifying scale factor of the target picture needs to be amplified when the first electronic device displays the target picture, and the target control instruction and the target amplifying scale factor are sent to the second electronic device in parallel, so that data interaction between the first electronic device and the second electronic device is reduced, data processing efficiency is improved, and meanwhile, data processing pressure of the electronic device performing device cooperation is reduced.

In one possible example, the double-click target picture event carries a display screen state identifier of the first electronic device, where the display screen state identifier is used to characterize a landscape screen or portrait screen usage state of a display screen of the first electronic device, and the determining a target magnification scaling factor required by the first electronic device to display the target picture includes: acquiring screen size information of the first electronic device stored at the local end of the switching device, wherein the screen size information of the first electronic device comprises: the method comprises the steps that screen size information of the first electronic equipment in a horizontal screen use state and screen size information of the first electronic equipment in a vertical screen state are displayed; determining target screen size information of the first electronic equipment from the screen size information of the first electronic equipment according to the display screen state identification of the first electronic equipment; and determining the target magnification scaling factor according to the target screen size information and the picture size information of the target picture.

In a specific implementation, under the condition that a screen is thrown in a computer mode, because the screen sizes of different electronic devices may be different, the picture content which can be displayed by the electronic device with a larger screen is usually larger, and taking the first electronic device as a computer and the second electronic device as a mobile phone as an example, because the picture content displayed by the mobile phone and the side of the computer can be asynchronous, after the picture is amplified according to the same target amplification scale factor, the picture range which can be viewed by a user through the computer is larger compared with the picture range which can be viewed by the side of the mobile phone due to the different screen sizes. At this time, under the condition of screen projection in the computer mode, the switching equipment jointly determines the target amplification scaling factor according to the screen size information of the computer to be projected and the picture size information of the target picture, so that a user can obtain a better display effect when viewing the mobile phone picture through the computer.

When the electronic device is connected with the interface of the switching device, the switching device can send request information to the electronic device to acquire screen size information of the electronic device and buffer the screen size information in the switching device content so as to improve response timeliness of subsequent data processing.

In a specific implementation, since the usage habits of users using different electronic devices are different, for example, the screen direction is usually fixed when using the electronic devices of the type such as a notebook computer or a desktop computer, when the electronic devices are connected to the switching device, the switching device only needs to request the electronic device to send screen size information, if the electronic device changes the screen usage state in the process of cooperating with other electronic devices through the switching device, for example, the screen usage state is changed from horizontal screen usage to vertical screen usage, or the screen usage state is changed from vertical screen usage to horizontal screen usage, that is, the screen is changed in length in the vertical and horizontal directions, at this time, the switching device can change the identification information according to the screen usage state from the electronic device, and change the screen size information of the electronic device cached at the local end.

For mobile phones, tablet computers and other types of electronic equipment, as the user frequently switches the use states of the horizontal screen and the vertical screen in the use process, if only one screen size is stored in the switching equipment initially, and indication information is sent to the switching equipment when the screen use state is switched every time later, the switching equipment is changed again to determine the new screen size, the switching equipment needs to consume more equipment resources in determining the screen size, the switching equipment stores two screen sizes, and the screen use state identification information is received to directly inquire and acquire the existing screen size information, so that the calculation amount of the switching equipment can be reduced.

In a specific implementation, after receiving the screen size information of the first electronic device, the switching device may store the screen size information in the cache, and after detecting that the first electronic device is disconnected from the first interface for a preset duration, the switching device may clear the screen size information of the first electronic device in the cache. Furthermore, the switching device may record the number of times of using the screen size of each electronic device, so that the screen size information of the electronic device with the largest number of times of using the screen size in the last time period may be stored in the specific storage area every preset time period, and then when the electronic device is connected to the switching device again, the screen size information may be directly obtained from the specific storage area without requesting to send the screen size information again.

In this example, the local end of the switching device stores the screen size information of the first electronic device, determines the target screen size information according to the use state of the horizontal screen or the vertical screen of the first electronic device, and determines the target amplification scaling factor together by integrating the target screen size information and the target picture size information, thereby being beneficial to improving the accuracy of determining the target amplification scaling factor.

In one possible example, the target screen size information includes: the first length of the target screen along the first direction and the second length of the target screen along the second direction, and the picture size information of the target picture comprises: the determining the target magnification scaling factor according to the target screen size information and the picture size information of the target picture includes: determining the target amplification scaling factor according to the first length and the third length in the case that the ratio of the first length to the second length is smaller than the ratio of the third length to the fourth length; and in the case that the ratio of the first length to the second length is greater than the ratio of the third length to the fourth length, determining the target amplification scale factor according to the second length and the fourth length.

The length in the first direction may be any one of the length and the width of the picture and the screen of the electronic device, and the length in the second direction may be the other one of the length and the width of the picture and the screen of the electronic device.

In a specific implementation, since the aspect ratio of the screen of the first electronic device is not necessarily the same as that of the target picture, if the screen length and the picture length in one direction are selected at will to determine the target magnification scaling factor, the magnified picture may not be displayed in the first electronic device completely, and the effect of displaying the picture is poor.

Therefore, when the length-width ratio of the target picture is different from the aspect ratio of the screen of the first electronic device, the target amplification scaling factor is determined according to the relatively longer side of the target picture, so that the display integrity of the target picture can be ensured and the display effect can be optimized under the condition of amplifying the target picture. Specifically, determining the target magnification scaling factor according to the second length and the fourth length may be: and determining the ratio of the second length to the fourth length as a target magnification scale factor, so that the length of the target picture with the size adjusted according to the target magnification scale factor in the second direction is equal to the length of the first electronic equipment screen in the second direction, namely the second length.

For example, referring to fig. 4 and 5, the original target picture size of the second electronic device side is shown as a picture a: a third length in the first direction is b, a fourth length in the second direction is a, and a screen size of the first electronic device: the first length in the first direction is d and the second length in the second direction is c.

As can be seen from fig. 4, d/c < b/a, i.e. the ratio of the first length to the second length is smaller than the ratio of the third length to the fourth length, in which case the target scaling factor is determined from b and d, i.e. from the first length and the third length. Specifically, the target scaling factor may be d/b, and after the target scaling factor is amplified, the size of the picture a in the first electronic device: the length in the first direction is b1, the length in the second direction is a1, and a1/b1=a/b, b1=d, at this time, the picture a is enlarged on the first electronic device side and displayed completely on the first electronic device.

As can be seen from fig. 5, d/c > b/a, i.e. the ratio of the first length to the second length is larger than the ratio of the third length to the fourth length, in which case the target scaling factor is determined from a and c, i.e. from the second length and the fourth length. Specifically, the target scaling factor may be c/a, and after the target scaling factor is amplified, the size of the picture a in the first electronic device: the length in the first direction is b1, the length in the second direction is a1, and a1/b1=a/b, c=a1, at this time, the picture a is enlarged on the first electronic device side and displayed completely on the first electronic device.

In this example, when the ratio of the first length to the second length is smaller than the ratio of the third length to the fourth length, the switching device determines the target amplification scaling factor according to the first length and the third length, and when the ratio of the first length to the second length is larger than the ratio of the third length and the fourth length, the switching device determines the target amplification scaling factor according to the second length and the fourth length, which is beneficial to improving the display effect of the target picture in the first electronic device after amplifying the target picture according to the determined target amplification scaling factor.

In one possible example, the determining the target magnification scaling factor according to the first length and the third length in a case where a ratio of the first length and the second length is smaller than a ratio of the third length and the fourth length includes: determining whether a ratio of the first length to the second length is greater than a first preset value; if yes, determining the target amplification scaling factor according to the second length and the fourth length; and if not, determining the target amplification scaling factor according to the first length and the third length.

If the ratio of the first length to the second length is greater than 1, the first length may be characterized as being greater than the second length.

Wherein determining the target magnification scaling factor from the second length and the fourth length may be: and determining the ratio of the second length to the fourth length as a target magnification scale factor, so that the length of the target picture in the second direction after the size is adjusted according to the target magnification scale factor is equal to the length of the first electronic equipment in the second direction, namely the second length. Accordingly, determining the target magnification scaling factor from the first length and the third length may be: and determining the ratio of the first length to the third length as a target magnification scaling factor, so that the length of the target picture in the first direction after the size is adjusted according to the target magnification scaling factor is equal to the length of the first electronic equipment screen in the first direction, namely the first length.

In a specific implementation, if the target amplification scaling factor is directly determined according to a longer side of the picture for a picture with a larger length difference in different directions, and the complete picture is displayed through the electronic device, details of the picture content may be difficult to clearly view, so that the picture display effect is poor.

It can be seen that, in this example, the switching device determines whether the ratio of the first length to the second length is greater than a first preset value; if so, determining the target amplification ratio coefficient according to the second length and the fourth length, and if not, determining the target amplification ratio coefficient according to the first length and the third length is beneficial to improving the display effect of the target picture in the first electronic device after the target picture is amplified according to the determined target amplification ratio coefficient.

In one possible example, where the ratio of the first length to the second length is greater than the ratio of the third length to the fourth length, determining the target magnification scaling factor from the second length and the fourth length includes: determining whether a ratio of the third length to the fourth length is greater than a second preset value; if yes, determining the target amplification scaling factor according to the first length and the third length; and if not, determining the target amplification scaling factor according to the second length and the fourth length.

It can be seen that, in this example, the switching device determines whether the ratio of the third length to the fourth length is greater than the second preset value; if yes, determining a target amplification scaling factor according to the first length and the third length; if not, determining the target amplification ratio coefficient according to the second length and the fourth length is beneficial to improving the display effect of the target picture in the first electronic device after amplifying the target picture according to the determined target amplification ratio coefficient.

In one possible example, the determining the target magnification scaling factor according to the target screen size information and the picture size information of the target picture includes: determining the target magnification scaling factor according to the first length and the third length, in the case where the ratio of the first length to the second length is equal to the ratio of the third length to the fourth length; or, in the case where the ratio of the first length to the second length is equal to the ratio of the third length to the fourth length, determining the target magnification scaling factor according to the second length and the fourth length.

In a specific implementation, the switching device may be preset to determine the target amplification scaling factor according to the length in the first direction when the aspect ratio of the screen is the same as the length and width ratio of the target image, or the switching device may be preset to determine the target amplification scaling factor according to the length in the second direction when the aspect ratio of the screen is the same as the length and width ratio of the target image, and further, in the case that the aspect ratio of the screen of the first electronic device is the same as the length and width ratio of the target image, the switching device may directly and quickly determine the target amplification scaling factor according to preconfigured information.

It can be seen that, in this example, in the case where the ratio of the first length to the second length is equal to the ratio of the third length to the fourth length, the switching device determines the target amplification scaling factor according to the first length and the third length; or under the condition that the ratio of the first length to the second length is equal to the ratio of the third length to the fourth length, the target amplification scale factor is determined according to the second length and the fourth length, so that the target amplification scale factor can be determined quickly and accurately, and a good picture display effect can be obtained.

In a specific implementation, the third length and the fourth length of any of the target pictures described in the above embodiments may be the original picture size of the target picture. Alternatively, it may also be determined by: the transferring device receives a target operation event of a double-click target picture, and the target operation event can also carry a double-click position (for example, a position of a point of a mouse in the target picture when a user double-clicks the target picture, or a position of a finger click in the target picture when the user touches the double-click target picture) in the target picture in the first electronic device, so that the transferring device can determine a target position corresponding to the double-click position of the target picture displayed by the first electronic device from an original target picture of the second electronic device in a coordinate conversion mode, for example, by determining the position of the double-click point of the user in the target picture without adjusting the proportion, and can perform object identification on the original target picture to identify an object including the target position in the target picture, for example, the user clicks the nose of the person, the switching device may identify a rectangular image area including a face image of the nose, further uses the length of the rectangular area in the first direction as a third length of the target picture, uses the length of the rectangular area in the second direction as a fourth length of the target picture, so as to perform a subsequent step of determining a target magnification scaling factor, and meanwhile, the switching device may send the target image to the first electronic device with the center point of the rectangular area as the center point of the target picture, so that after the second electronic device adjusts the scale of the target image, the first electronic device may display the target image in such a manner that the center point information of the target image coincides with the center point of the first electronic device when the target image is displayed, so that the face image of greater interest of the user may be displayed in the middle of the display screen, and when the overall picture size exceeds the display screen size of the first electronic device after the target picture is scaled, the partial image area concerned by the user can be clearly displayed in the display screen of the first electronic device.

For the situation that the user wants to view the picture details, the third length and the fourth length of the target picture are determined in the above manner, so that the user can clearly see the partial area of the picture which is more focused by the user in the first electronic device.

Further, the user may select to configure the application function identifier of the third length and the fourth length to the switching device by selecting the second electronic device, and if the application function identifier is not configured, the switching device may default to the original picture size of the target picture as the third length and the fourth length.

In addition, in order to further ensure the definition of the image display, the switching device may further pre-configure a threshold value of the target amplification scaling factor, and after determining the target amplification scaling factor according to the foregoing steps, if the target amplification scaling factor is greater than the threshold value, the threshold value may be sent to the second electronic device as a final target amplification scaling factor.
