In some embodiments, the download instruction is triggered by the terminal device, the terminal device sends the download instruction to the server, and the server sends the download instruction to the controller of the display device. In this case, the downloading instruction is triggered by the user operating the terminal device, for example, the user operates a menu in a user interface of the terminal device to select a file in the display device for downloading, and the terminal device may be a smart phone or another display device.

For example, as shown in fig. 8, when a user manages a file in a display device using a terminal device, the user may select the display device through an application installed in the terminal device and enter a management page, and when the user enters the management page, the terminal device needs to acquire and display information of the file stored in the display device, at this time, the terminal device may send a download instruction to the display device to download file directory information in the display device, for example, to download a thumbnail of the file, in which case, the download instruction sent by the terminal device is used to download a plurality of thumbnails to the terminal device. After the directory information of the multiple files in the display device is displayed in the user interface of the terminal device, for example, thumbnails of the files are displayed, for example, as shown in fig. 8, the user may further operate the user interface of the terminal device to select multiple files, for example, select multiple picture files or select multiple video files, and trigger a download button to download the multiple files locally to the terminal device.

S602, the display device transmits the files to the server in parallel.

After receiving the download instruction, the display device transmits the multiple files to the server in parallel according to identifiers of the multiple files carried in the download instruction, where the identifiers of the files may be names of the files, unique serial numbers of the files, MD5 values of the files, and the like, which is not limited in this embodiment. It should be noted that, in some embodiments, the display device may authenticate the received download instruction, determine whether the user account is authorized to download the file in the display device according to the user account corresponding to the download instruction sent by the terminal device carried in the download instruction, and if the authentication is successful, the display device transmits the multiple files to the server in parallel.

In this embodiment, the display device may transmit the plurality of files to the file management device in parallel by establishing a plurality of threads, and the transmission of each file is independent of each other.

S603, the server sends the address information of each file in the plurality of files to the display device. Because the display device sends each file to the server in a parallel transmission mode, after receiving one file, the server can correspondingly process the file and return the address information corresponding to the file to the display device, thereby realizing that the address information of each file is respectively sent to the display device.

S604, the display device sends the address information of each file to the terminal device, and the address information of each file is used for indicating the terminal device to download each file.

It can be understood that, since the display device transmits the plurality of files to the file management device in parallel, the transmission of the files is independent, and therefore, the process that the display device receives the address information of each file is also independent, and the display device can send the address information of one file to the terminal device after receiving the address information corresponding to one file returned by the server, without waiting for the address information of all files.

In the embodiment, the display device performs data interaction with the terminal device through the server, cross-network transmission of data is achieved, and stability of a data transmission link is guaranteed.

Based on the above, S603 and S604 are further explained.

The files mutually transmitted between the display device and the terminal device can be stored in the cloud device, so that after receiving each file sent by the display device, the server can determine whether each file is stored in the cloud device according to the identifier of each file; if the first file is stored in the cloud device, sending address information of the first file to the first device, wherein the first file is any one of a plurality of files; if the second file is not stored in the cloud equipment, the second file is sent to the cloud equipment, address information of the second file returned by the cloud equipment is received, and the address information of the second file is sent to the first equipment; the second file is any one of a plurality of files.

In an example, the display device sends a file 1, a file 2 and a file 3 to the server respectively in a parallel transmission mode, and after receiving the file 1, the server determines that the file 1 is not stored in the cloud device, so that the server sends the file 1 to the cloud device, receives address information of the file 1 returned by the cloud device, and sends the address information of the file 1 to the display device; after receiving the file 2, the server determines that the file 2 is stored in the cloud device, and for the file stored in the cloud device, address information of preselected storage is recorded in the server, so that the server directly sends the address information of the file 2 to the display device; file 3 is similar.

In addition, in S604, the displaying device sends the address information of each file to the terminal device, which may specifically include that the controller of the displaying device assembles the address information of each file and the identifier of each file according to the sequence of receiving the address information and sends the assembled address information and identifier of each file to the server, so that the server sends the address information of each file and identifier of each file to the terminal device.

As described above, the server processes the received multiple files respectively and sends the address information of each file to the display device, because the multiple files are transmitted in parallel, that is, the transmission of each file is independent, and there may be a portion of the file stored in the cloud device and a portion of the file not stored in the cloud device, the address information of each file returned to the display device by the server has a sequence, that is, each time the server receives a file, the server processes the file and returns the address information of the file to the display device. And each time the display device receives the address information of one file, the address information and the corresponding file identification are assembled and then sent to the server, and then the server sends the assembled information to the terminal device. The identification of the file may include one or more of a file name, a unique serial number of the file, and an MD5 value of the file. For example, the display device assembles the address information of the file and the corresponding file name and sends the assembled information to the server, and then the server sends the assembled information to the terminal device, so that the terminal device can download the file from the address corresponding to the address information after receiving the information, and can display the file name in a display list of the terminal device, which is convenient for browsing.
