An exemplary description of a data processing method for a screen according to an embodiment of the present invention is provided below with reference to fig. 1.
As shown in fig. 1, a data processing method for a screen transmission is provided, and the method specifically includes the following steps:
s101, dynamically generating an applet two-dimensional code by the screen transmission device according to a preset first time interval;
in this embodiment, when the screen transmission device is connected for the first time, a network configuration operation is required, the network configuration operation dynamically generates and displays an applet two-dimensional code, a new applet two-dimensional code can be generated every two minutes or every five minutes, and the time interval can be set as required.
S103, the terminal scans the applet two-dimensional code generated by the screen transmission device and logs in the corresponding applet;
in this embodiment, the terminal identifies the applet two-dimensional code generated by the screen transmitting device through the one-sweep function, and after the identification is successful, the terminal automatically jumps to the applet corresponding to the applet two-dimensional code. The sweep-sweep function may be a sweep-sweep function integrated by the terminal system, or a sweep-sweep function in the application program, which is not limited herein. If the terminal system integrated sweep function is used, automatic jump to the corresponding application program and opening of the corresponding applet can be realized, for example: and automatically jumping to the WeChat application program by scanning the two-dimensional code of the WeChat applet, and opening the corresponding applet.
S105, extracting first information contained in the applet two-dimensional code;
specifically, the first information may include: and presetting a regular random code, an MA C address of the screen transmission device and the screen transmission code, so that the terminal can finish the operations of network allocation and screen transmission connection establishment according to the first information. The first information includes information not limited thereto but may include other desired information.
And S107, establishing connection with the screen transmission device according to the first information and transmitting a screen.
In this embodiment, the terminal performs network distribution on the screen transmission device by extracting information included in the applet two-dimensional code, and transmits the extracted screen transmission code to the logged applet, where the logged applet establishes screen transmission connection with the screen transmission device according to the screen transmission code and a preset frequency until the screen transmission connection is successfully established with the screen transmission device or the screen transmission connection is not established for more than a preset time.
In this embodiment, when a user needs to transfer the screen content of the terminal to other display devices through the screen transfer device, because the screen transfer device is not used for the first time or is not in a network connection state, the screen transfer device needs to be configured with a network, so that the screen transfer device can be connected with the terminal under the same wireless network. It should be noted that the wireless network may be a wireless network in a home, or may be a hotspot transmitted by a terminal, a screen transmission device or other devices, which is not limited herein.
When the screen transmission device completes the distribution network, as the screen transmission code is contained in the applet two-dimensional code, the terminal automatically acquires the screen transmission code when the terminal identifies the applet two-dimensional code through scanning, so that the terminal can automatically establish connection with the screen transmission device through the applet, and the screen transmission code is prevented from being manually input again to establish connection, the screen transmission step is realized, and the user experience is improved. In the embodiment, the screen transmission device generates the applet two-dimensional code, so that the terminal does not need to download the application program corresponding to the screen transmission device to realize the network distribution, the network distribution and the subsequent screen transmission operation can be directly completed through the applet, and the situation that the downloaded corresponding application program occupies more memory is avoided; and, can include required information in the applet two-dimensional code, for example join in marriage net relevant information and pass the screen code for the terminal is after joining in marriage the net to pass the screen device, can realize establishing and pass the screen connection and carry out the operation of passing the screen through the applet, makes the screen of passing for the first time more convenient.
Specifically, as shown in fig. 2, in step S107, the establishing connection with the screen transmission device according to the first information and screen transmission includes:
s1071, extracting the first information, and acquiring a corresponding encryption mode by a background server according to the random code of the preset rule and the MAC address of the screen transmission device;
specifically, after the terminal scans the applet two-dimensional code generated by the screen transmission device, the terminal jumps to the corresponding applet, and the applet can be defaulted to communicate with the background server because the applet is developed for the manufacturer of the screen transmission device. The terminal can obtain the encryption mode and decryption mode corresponding to the current random code by extracting the random code of the preset rule in the two-dimensional code of the small program and the MAC address of the screen transmission device and communicating with the background server.
In one embodiment, the random code of the preset rule may be a separate random code, and the screen transmitting device has a rule set at the time of delivery, for example, the random code is obtained by calculation according to the time-seconds of the current time, or a random number generation formula is adopted to generate the random code, and the preset rule is bound with the MAC address of the screen transmitting device.
Specifically, when the first time interval is set to 3 minutes and the current time is 14 hours, 23 minutes and 56 seconds, the random code is obtained by taking the number of digits of the current time minutes, that is, the random code of the screen transmission device at the current time is 3, and when the random code is updated next time, the random code is updated to be 6. As described above, the random code may also be generated by a random number formula, and the number of bits of the random code may be adjusted according to the number of encryption modes, not limited to a one-bit number.
In another embodiment, the random code of the preset rule may be obtained by combining the MAC address of the screen device with other information, for example, by extracting the number of the specific location of the MAC address, and calculating the random code in combination with the current time.
Specifically, when the last digit of the MAC address of the screen transmission device is B and the current time is 14 hours 23 minutes 56 seconds, the random code is obtained by taking the digit of the current time minute and adding the last digit of the MAC address B, that is, the random code is 14. It should be noted that the above manner is merely an example, and the generation manner of the random code is not limited thereto. And, it can be understood that the more complex the rule of the random code generation, the higher the security performance thereof.
It will be appreciated that the random code of the preset rule, regardless of how it is generated, is stored in the background server along with the MAC address of the pass-through device. The background server combines the MAC address and the random code of the screen transmission device, so that other information stored in the background server by the screen transmission device can be queried.
Further, the background server stores the MAC address of the screen transmission device, the random code of the preset rule, the encryption mode and the corresponding decryption mode. After the terminal acquires the MAC address of the screen transmission device and a random code with a preset rule, the terminal can acquire an encryption mode through a background server; and because the screen transmission device generates the random code, the screen transmission device can obtain a corresponding decryption mode through the random code.
Specifically, the screen transmission device can have various encryption modes and various corresponding decryption modes, and the diversification of the encryption modes can prevent information leakage caused by interception of WIFI information when the terminal sends the WIFI information. It can be understood that if the screen transmission device only adopts a single encryption mode or directly adopts the MAC address to encrypt, when the terminal transmits the WIFI information in a broadcast mode, other terminals or the screen transmission device can also acquire the WIFI information due to the broadcast mode. And, other terminals or pass screen device accessible are broken the information of receiving to obtain this WIFI information, can cause information leakage this moment. In this embodiment, the screen transmission device may have multiple encryption modes by introducing the random code with the preset rule, and the multiple encryption modes may be dynamically changed, that is, the encryption modes used by the screen transmission device may be different at different moments, even if the MAC address of the screen transmission device is obtained, since the information adopts the dynamic encryption mode, other information cannot be easily broken from the monitored information, so that the data security is greatly improved.
Further, although the screen transmission device has multiple decryption modes and multiple corresponding decryption modes, the screen transmission device and the terminal both know the preset rule of the random code, so that the screen transmission terminal can acquire what decryption mode needs to be used for decrypting data at the moment through the generated random code, and does not need to adopt multiple decryption mode polling modes for decryption when receiving the data, thereby improving the data security, improving the receiving efficiency and enabling the network distribution process to be quicker.
S1072, encrypting and sending the first WIFI information connected with the terminal through the encryption mode, so that the screen transfer device can successfully decrypt the first WIFI information by using a decryption mode corresponding to the encryption mode after receiving the encrypted first WIFI information and is connected to the corresponding first WIFI;
specifically, the terminal is currently connected with first WIFI information, after the terminal scans the applet two-dimensional code of the screen transmission device, the terminal jumps to the corresponding applet, and the encryption mode which needs to be adopted at present is acquired through a background server by combining the MAC address and the random code of the screen transmission device, and the first WIFI information is encrypted through the encryption mode and then sent out through electromagnetic waves. Because the information is sent through electromagnetic waves, all other terminals and other screen transmission devices can receive the information, however, only the screen transmission device has a corresponding decryption mode, the device decrypts the monitored electromagnetic wave data by adopting the decryption mode, and when the first WIFI information is acquired, the device is automatically connected to the corresponding first WIFI. If the current first WIFI information cannot be connected to the first WIFI network, displaying network distribution failure information, such as 'network distribution failure, retry request', on the target display device, and updating the applet two-dimensional code. By the network distribution method, the security and convenience of the network distribution are greatly improved, and after the user scans the applet two-dimensional code, the network distribution can be completed without complicated operation. It should be noted that, the electromagnetic wave may be transmitted by a conventional single antenna or by multiple antennas; the first WIFI information may be WIFI information connected to a 2.4G frequency band, or WIFI information connected to a 5G frequency band, which is not limited herein, and may be selected as required.
S1073, establishing connection with the screen transmission device through the screen transmission code and starting screen transmission.
Specifically, since the first information further includes a screen transfer code, the terminal can synchronously acquire the screen transfer code from the applet two-dimensional code during scanning. After the screen transmission device is matched with the network, the screen transmission code is automatically input through the small program and the screen transmission connection is established with the screen transmission terminal, and the screen transmission operation is performed through the small program, including the operations of starting screen transmission, ending screen transmission, disconnecting and screen transmission, such as the operations of changing the screen transmission resolution, the picture code rate and the like. Through the mode, after the user scans the two-dimension code of the applet, the network distribution can be directly completed, the screen connection can be automatically established, the screen projection can be started, the operation is simple, and the user experience is excellent.
In one embodiment, after the connection is established with the screen transmission device through the screen transmission code and screen transmission is started, the method further comprises:
and S1074, if the screen transmission device detects that the screen transmission device is connected to a wireless network, updating the applet two-dimensional code, wherein the updated applet two-dimensional code comprises second information.
Specifically, the second information is used for prompting other users who sweep codes, and the screen transmission device is in a screen transmission state. By the mode, after the screen transmission device detects that the screen transmission device completes the distribution network, the small program two-dimensional code is updated because the screen transmission device does not need to carry out the distribution network. And the situation that other users scan the applet two-dimensional code and simultaneously carry out network distribution at the same time, so that connection confusion is caused is avoided.
Further, the second information included in the updated applet two-dimensional code is null or information indicating the status thereof. For example: when the second information is empty, when other users scan the applet two-dimensional code at the moment, no operation is performed; when the second information is information indicating the state of the second information, when other users scan the applet two-dimensional code at the moment, feedback is obtained as 'the existing other users are operating'. Therefore, when the current terminal is in operation, other terminals are also operated at the same time, and the network distribution connection is disordered or the follow-up screen transmission is disordered.
Further, after the updating of the applet two-dimensional code, the method further includes:
and S1075, if the screen transmission device does not detect the screen transmission data within the preset second time, feeding back the screen transmission failure information, and updating the applet two-dimensional code according to the preset rule.
Specifically, when the screen transmission device detects that the network allocation is successful in the preset second time, but the screen transmission data is not detected, it may be determined that the screen transmission action is abnormal, where the abnormality may be abnormal in network condition, or abnormal in the current connection terminal, etc., so that the screen transmission data is not normally sent to the screen transmission device, and at this time, feedback screen transmission failure information on the target display device, for example: "network allocation succeeds, but screen transmission fails"; and updating the applet two-dimensional code according to a preset rule, so that other terminals or current terminals can scan the two-dimensional code, perform connection screen transmission operation and start screen transmission.
Further, the updating the applet two-dimensional code according to a preset rule specifically includes:
and updating the applet two-dimensional code according to a preset third time interval, wherein the updated applet two-dimensional code comprises third information.
Specifically, the third information includes: and the screen transmission code and the connected WIFI information of the screen transmission device.
It can be understood that, by adopting the data processing method, the first connection of the screen transmission device is more convenient, the network distribution can be realized and the screen transmission connection can be established only by scanning the applet two-dimensional code by the terminal, however, after the network distribution is realized by the screen transmission device, the terminal may not start screen transmission due to other reasons, for example: the terminal crashes, the applet flashes back, or the terminal can not play the content of the screen to be transmitted and other emergency situations; or the terminal has finished transmitting the screen, and needs to be switched to other terminals to continue transmitting the screen. When the situation occurs, if the information contained in the applet two-dimensional code stays in the second information, no terminal can transmit the screen at present, and user experience is seriously affected. Therefore, a third time interval is set for updating the applet two-dimensional code to include third information. The third time interval may be the same as the first time interval or may be different. And the user scans the applet two-dimensional code containing the third information to realize the screen transmission operation.
Further, the third information includes: the screen transmission code and the WIFI information connected with the screen transmission device; and the third information is used for establishing network connection between the screen transmission device and the scanning terminal and carrying out screen transmission.
It can be understood that when the screen transfer device updates the applet two-dimensional code to include the third information, the screen transfer device has completed the first network allocation operation, and other terminals or terminals for which the network allocation is performed are not required to perform the network allocation operation when the screen transfer device transfers the screen again, so that the connection can be directly performed and the screen transfer can be started. However, in the prior art, in this scenario, the terminal needs to be connected to the same WIFI as the screen transmission device first, so that the terminal is in the same network, and the screen transmission code is manually input to establish the screen transmission connection, which is too cumbersome. In this embodiment, when the screen transmission device updates the applet two-dimensional code to include third information, the third information includes: the screen transmission code and the WIFI information connected with the screen transmission device; and the third information is used for establishing network connection between the screen transmission device and the scanning terminal and carrying out screen transmission.
It can be understood that when the terminal scans the applet two-dimensional code containing the third information, the terminal can jump to the corresponding applet, and the terminal is automatically connected to the wireless network corresponding to the screen transmission device by acquiring the WIFI information connected to the screen transmission device in the third information. And because the third information contains the screen transmission code, the terminal can also acquire the screen transmission code and automatically establish screen transmission connection with the screen transmission device so as to realize screen transmission operation.
