And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

In practical applications, data transmission is often required between the mobile terminal and the display device, and the data may be files with large data volume, such as audio files, video files, images, and the like, or information with small data volume, such as control information. In a conventional manner, when data is transmitted between the mobile terminal and the display device, the data transmission efficiency is low because the communication link, for example, a bluetooth communication link, has poor stability.

Fig. 5 is a diagram of an applicable scenario of a data transmission method according to an embodiment of the present application. Referring to fig. 5, the present scenario is a data transmission system suitable for data transmission between a display device and a mobile terminal. Among them, the data transmission system 500 includes: the mobile terminal 501 can perform data transmission service with the display device 502 through the physical server 503 and the cloud storage server 504.

The mobile terminal 501 may install an application program corresponding to the data transmission service, the mobile terminal 501 may implement connection communication with the physical server 503 through a first network communication protocol, and the mobile terminal 501 may implement connection communication with the cloud storage server 504 through a second network communication protocol. For example, the mobile terminal 501 may send a data acquisition request instruction to the physical server 503 through the first network communication protocol; the mobile terminal 501 may download the file from the cloud storage server 504 through the second network communication protocol, or the mobile terminal 501 may upload the file to the cloud storage server 504 through the second network communication protocol. The first network communication protocol and the second network communication protocol may be the same or different.

The display device 502 includes a memory for storing files. The display device 502 may be communicatively coupled to the physical server 503 via a first network communication protocol, and the display device 502 may also be communicatively coupled to the cloud storage server 504 via a second network communication protocol. For example, the display device 502 may send information of related files stored in the memory, for example, information of directory files, the number of files, and the like, to the physical server 503 through the first network communication protocol; the display device 502 may also upload files to the cloud storage server 504 via the second network communication protocol and download files from the cloud storage server 504 via the second network communication protocol.

Illustratively, the display device 502 may include a memory that is a Network Attached Storage (NAS) module, where the NAS module is data-centric, separates the storage device from a server, and centrally manages data through the physical server 503, thereby releasing bandwidth, improving performance, and reducing device cost. The NAS module may also be referred to by other names such as NAS storage device and network storage, and the present embodiment does not limit this. Of course, the display device 502 may also include other types of memory such as a USB flash drive, a removable hard drive, and so forth.

The physical server 503 is used to implement transmission of information between the mobile terminal 501 and the display device 502, and data management for data transmission through the cloud storage server 504. In one possible implementation, the physical server 503 may include: a message server 5031 and a service server 5032, wherein the message server 5031 is used for realizing the transmission of information between the mobile terminal 501 and the display device 502; the service server 5032 may be equipped with a file management system to implement data management of data transmission through the cloud storage server 504.

It should be noted that the message server 5031 and the service server 5032 may be integrated together or may be separately disposed, which is not limited in this embodiment of the application.

The cloud storage server 504 is configured to implement file transmission between the display device 502 and the mobile terminal 501, for example, the display device 502 uploads a file to the cloud storage server 504, and the mobile terminal 501 may download the file from the cloud storage server 504; for another example, the mobile terminal 501 may upload a file to the cloud storage server 504, and the display device 502 downloads the file from the cloud storage server 504. The resources of the cloud storage server 504 can be used at any time and can be expanded as required according to actual application conditions, so that the efficiency of data transmission can be improved by realizing file transmission between the display device 502 and the mobile terminal 501 through the cloud storage server 504, and flexible infrastructure can be supported.

On the basis of the data transmission system shown in fig. 5, when the display device and the mobile terminal perform data transmission, data transmission can be performed according to a transmission mode corresponding to information to be transmitted, information with a small data amount can be transmitted through a message server in a physical server, and information with a large data amount, such as video files, audio files and the like, can be transmitted through a cloud storage server, so that the problem of transmission failure caused by unstable communication links is avoided, and the stability of data transmission and the data transmission efficiency are improved.

The data interaction between the display device and the mobile terminal can be divided into two scenes, namely a scene I: the mobile terminal downloads the file from the display equipment; scene two: and the mobile terminal uploads the file to the display device.

In the following, two different scenarios are described in detail how data transmission is performed between the display device and the mobile terminal through the physical server and the cloud storage server.

Scene one: mobile terminal downloading files from display device

In scenario one, in combination with the display device shown in the foregoing embodiment, the communication interface of the display device may receive, from a message server included in the physical server, a first information acquisition instruction sent by the mobile terminal; and the controller of the display equipment responds to the first information acquisition instruction and sends the first information to the mobile terminal through the determined transmission mode corresponding to the first information.

In one possible implementation manner, the message server included in the physical server is a message server based on MQTT protocol. Namely, two transmission modes exist between the display device and the mobile terminal, which are respectively: the method comprises a transmission mode of a message server based on an MQTT protocol and a transmission mode of a cloud storage server. The transmission mode of the message server based on the MQTT protocol is suitable for transmitting information with small data volume, such as directory files of a storage (e.g., NAS module) of the display device; the transmission mode through the cloud storage server is suitable for transmitting information with large data volume, such as files stored in a storage (e.g., NAS module) of the display device, including but not limited to audio files, video files, images, documents, and the like.

That is, in scenario one, when the mobile terminal downloads the target file from the display device, the display device sends information related to the file in the memory of the display device with a small data amount to the mobile terminal through the message server, and sends the target file with a large data amount to the mobile terminal through the cloud storage server.

The following describes a specific implementation manner of downloading data from the display device by the mobile terminal in detail with reference to the embodiments shown in fig. 6a and 6 b.

Fig. 6a is a flowchart of a data transmission method according to an embodiment of the present application. The data transmission method in this embodiment is a scenario in which the mobile terminal downloads data from the display device. In this embodiment, a storage included in the display device is used as the NAS module, and the first information requested to be acquired by the first information acquisition instruction is a directory file of the NAS module of the display device. As shown in fig. 6a, the method of the present embodiment includes:

s101, the mobile terminal sends a first information acquisition instruction to the display device, wherein the first information acquisition instruction is used for requesting to acquire first information, and the first information comprises a directory file of an NAS module of the display device.

Correspondingly, the communication interface of the display device receives a first information acquisition instruction sent by the mobile terminal device through the message server.

In this embodiment, since the first information acquisition instruction includes a small amount of data, the mobile terminal may transmit the first information acquisition instruction to the display device through the message server.

Optionally, the first information obtaining instruction may include an account corresponding to the mobile terminal, an account corresponding to the display device, and indication information of the first information.

Specifically, the mobile terminal sends a first information acquisition instruction to the message server, and the message server finds the corresponding display device according to the account corresponding to the display device included in the first information acquisition instruction and sends the first information acquisition instruction to the corresponding display device.

S103, the display device sends the first information to the mobile terminal through the message server.

In one possible implementation manner, the controller of the display device may determine a transmission manner corresponding to the first information according to the data amount of the first information. The data amount of the first information may be determined according to indication information of the first information included in the first information acquisition instruction. For example, if the data amount of the first information is less than the preset data amount, the controller determines that the transmission mode corresponding to the first information is a mode of transmission through the message server, and the display device may send the first information and information for indicating that the first information is transmitted through the message server to the mobile terminal; if the data volume of the first information is larger than the preset data volume, the controller can determine that the transmission mode corresponding to the first information is a mode of transmission through the cloud storage server, and the display device can send the address information of the first information in the cloud storage server and information used for indicating the information to be transmitted through the message server to the mobile terminal through the message server, so that the mobile terminal can obtain the first information according to the address information of the first information in the cloud storage server.

In other possible implementations, the controller of the display device may determine the transmission mode corresponding to the first information according to the type of the first information. In the network communication protocol, different types of information correspond to different data amounts, and the controller may determine a transmission mode corresponding to the first information according to the type of the first information.

In another possible implementation manner, the message server may determine the transmission manner corresponding to the first information according to the data amount of the first information. Exemplarily, if the data volume of the first information is smaller than the preset data volume, the message server determines that the transmission mode corresponding to the first information is a mode of transmission through the message server, and the message server sends the first information to the mobile terminal; if the data volume of the first information is larger than the preset data volume, the message server can determine that the transmission mode corresponding to the first information is a mode of transmission through the cloud storage server, and the message server sends the address information of the first information in the cloud storage server to the mobile terminal, so that the mobile terminal can obtain the first information according to the address information of the first information in the cloud storage server.

In this scheme, since the data volume of the directory file of the NAS module is smaller than the preset data volume, the transmission mode of the first information is a transmission mode through the message server, and therefore, the display device sends the directory file of the NAS module to the mobile terminal through the message server.

In this embodiment, when the mobile terminal acquires the first information with a small data size from the display device, the mobile terminal sends a first information acquisition instruction to the display device; the display equipment responds to the first information acquisition instruction, and determines a transmission mode corresponding to the first information as a transmission mode through the message server according to the first information; the display device sends the first information to the mobile terminal through the message server.

Optionally, on the basis of the embodiment shown in fig. 6a, before S103, the method may further include:

s102, the display equipment authenticates the first information acquisition instruction.

If the authentication is passed, executing S103;

if the authentication is not passed, the display device may return information indicating that the authentication for the mobile terminal is not passed to the mobile terminal through the message server, and for example, the display device may send indication information of "without permission" to the mobile terminal through the message server to indicate that the authentication for the mobile terminal is not passed. Of course, in practical applications, the display device may also return other information for indicating that the authentication of the mobile terminal is not passed to the mobile terminal, and is not limited to the description in the above example, for example, the display device sends the indication information of "verification failed" to the mobile terminal through the message server.

In this step, the display device may authenticate the first information obtaining instruction according to the account corresponding to the mobile terminal included in the first information obtaining instruction. If the authentication is passed, the mobile terminal is indicated to have the authority of acquiring the first information; if the authentication is not passed, the mobile terminal does not have the authority of acquiring the first information. The security of the file stored in the memory of the display device is ensured by authenticating the first information acquisition instruction.

Optionally, on the basis of the embodiment shown in fig. 6a, after S103, the method may further include:

and S105, the mobile terminal displays the directory file of the NAS module of the display equipment on a user interface according to the first information.

In this embodiment, the first information is a directory file of a NAS module of the display device, and after receiving the first information from the message server, the mobile terminal may display the directory file of the NAS module of the display device on the user interface according to the first information, and for example, the directory file of the NAS module may include: the information of the file folders, the number of the file folders, the names of the files included in the file folders, other attribute information and the like included in the NAS module.

In this embodiment, the mobile terminal provides a visual interactive interface for the user by displaying the directory file of the NAS module of the display device; and then, the user can select the target file by operating the interface of the mobile terminal, the mobile terminal generates a target file downloading instruction based on the operation of the user, and the target file downloading instruction is sent to the display equipment through the message server to download the target file.

Fig. 6b is a flowchart of a data transmission method according to an embodiment of the present application. The data transmission method in this embodiment is a scenario in which the mobile terminal downloads data from the display device.

As shown in fig. 6b, the method of the present embodiment includes:

s201, the mobile terminal sends a first information acquisition instruction to the display device, wherein the first information acquisition instruction is used for requesting to download the target file. Correspondingly, the display equipment receives a first information acquisition instruction sent by the mobile terminal equipment through the message server.

This step is similar to step S101 in the embodiment shown in fig. 6a, except that the indication information of the first information included in the first information acquisition instruction is different. For example, in this embodiment, the first information acquisition instruction may include indication information of the target file and information for indicating downloading of the target file, where the indication information of the target file is, for example, a file name of the target file.

S203, the display device responds to the first information acquisition instruction and sends the address information of the first information in the cloud storage server to the mobile terminal through the message server.

The implementation manner of determining the transmission manner corresponding to the first information in this embodiment is similar to step S103 in the embodiment shown in fig. 6a, and reference may be made to the detailed description in the embodiment shown in fig. 6a, which is not described herein again.

In this embodiment, the first information is an object file stored in a memory of the display device, and the data volume of the object file is usually large, so that the transmission mode corresponding to the first information is a mode of transmission through the cloud storage server.

It should be noted that the address information of the first information in the cloud storage server may be a Uniform Resource Locator (URL) corresponding to the first information in the cloud storage server, and the URL may include: the identification of the cloud storage server (such as a host domain name of the cloud storage server) and the file address of the first information in the cloud storage server.

In some cases, the address information of the first information sent by the display device to the mobile terminal at the cloud storage server may be information obtained by the display device through reassembly at a corresponding URL of the cloud storage server according to the first information.

Alternatively, the display device may acquire address information of the target file in the cloud storage server from the file management system.

S205, the mobile terminal acquires the first information according to the address information of the first information in the cloud storage server.

In the scheme, the data volume of the first information (namely the target file) is large, so that the mobile terminal can acquire the target file through the cloud storage server.

Specifically, the display device enables the mobile terminal to download the target file from the cloud storage server according to the address information of the target file in the cloud storage server by indicating the address information of the target file in the cloud storage server to the mobile terminal.

In addition, since the data volume of the address information of the target file in the cloud storage server is small, the display device may transmit the address information of the target file in the cloud storage server to the mobile terminal through the message server.

In the embodiment, when the mobile terminal downloads the target file from the display device, the mobile terminal sends a first information acquisition instruction for requesting to download the target file to the display device; the display equipment responds to the first information acquisition instruction, and determines a transmission mode corresponding to the first information as a mode of transmission through the cloud storage server according to the first information; the display device sends first information to the mobile terminal through the cloud storage server.

If the authentication is passed, the mobile terminal is indicated to have the authority of acquiring the first information; if the authentication is not passed, the mobile terminal does not have the authority of acquiring the first information. In the step, the security of the file stored in the NAS module of the display device is ensured by authenticating the first information acquisition instruction.

s2021, the display device calls an interface of the file management system.

In some cases, the first information may be stored in the cloud storage server because the display device previously uploaded the first information to the cloud storage server, or may upload the first information to the cloud storage server by another display device or a mobile terminal or another electronic device, and therefore, the display device determines whether the first information has been uploaded to the cloud storage server by calling an interface of the file management system.

If it is determined that the first information is uploaded to the cloud storage server, the file management system may directly return the address information of the first information in the cloud storage server to the display device, that is, execute S2042.

In other cases, the display device may not upload the first information to the cloud storage server before, or other mobile terminals or electronic devices including the first information may not upload the first information to the cloud storage server, and the first information is not stored in the cloud storage server, so that the display device calls the file management system to determine whether the first information is uploaded to the cloud storage server.

If the first information is not uploaded to the cloud storage server, the display device is required to upload the first information to the cloud storage server, and address information of the first information in the cloud storage server is returned to the display device after the first information is uploaded. I.e., executes S2023 to S2025.

S2022, the file management system sends address information feedback information to the display device, wherein the address information feedback information includes address information of the first information in the cloud storage server.

Specifically, if the file management system determines that the first information is uploaded to the cloud storage server, the file management system sends address information feedback information to the display device, wherein the address information feedback information includes address information of the first information in the cloud storage server, and then the display device can send the address information of the first information in the cloud storage server to the mobile terminal through the message server.

S2023, the file management system sends a first information uploading instruction to the display device.

Specifically, the file management system determines that the display device is required to upload the first information, the file management system may send a first information upload instruction to the display device, and accordingly, the display device receives the first information upload instruction sent by the file management system, where the first information upload instruction is used to instruct the display device to upload the first information to the cloud storage server.

S2024, the display device uploads the first information to the cloud storage server through the file management system.

Correspondingly, the cloud storage server receives the first information uploaded by the display device through the file management system. Specifically, the file management system may generate a corresponding log according to the first information uploaded by the display device, so as to record an operation of uploading the first information by the display device, and acquire address information of the first information in the cloud storage server.

After S2024, execution returns to S2022.

The file management system can acquire the address information of the first information in the cloud storage server, and then can return the address information of the first information in the cloud storage server to the display device.

It should be noted that S2021 to S2024 may also be executed before S2020, and are not limited to the execution sequence shown in fig. 6 b.

In the embodiment, a service server, namely a file management system, in the physical server is used for managing data transmission services of a large number of users through the cloud storage server, so that resource consumption caused by the fact that the large number of users directly and frequently access the cloud storage server is avoided, and the data management efficiency of the cloud storage server is improved.
