In the related art, it is not possible to browse a file or control a file display on a display device, and browse a file or control a file display on other terminal devices at the same time.
In order to solve the above problem, an embodiment of the present application provides a file transfer system, as shown in a schematic diagram of a file transfer system framework shown in fig. 6, where the file transfer system shown in fig. 6 includes a mobile terminal 300A and a display device 200. The display device 200 shown in fig. 6 includes a hard disk server 200A and a hard disk 200B. In this embodiment, the hard disk server 200A is a server integrated inside the display device 200, and in some embodiments, the hard disk server 200A may also be used as an external device of the display device 200, and establishes a connection with the display device 200 through a network. Mobile terminal 300A acquires a file from hard disk 200B through hard disk server 200A.
In the embodiment of the application, the mobile terminal needs to establish connection with the display device, and after the mobile terminal establishes communication with the display device, the display device detects whether the mobile terminal is authorized. If not, the mobile terminal actively pushes an authorization request to the display device to obtain the authorization of the display device. And after receiving the request, the display equipment authorizes the mobile terminal to perform the action of synchronizing the file to the display equipment according to the actual condition, and authorizes the mobile terminal to acquire the file from the display equipment. Each display device can authorize multiple mobile terminals simultaneously, and each mobile terminal can also be authorized by multiple display devices.
Illustratively, as shown in fig. 7, after the mobile terminal and the display device are connected to the same WI-FI or hot spot, the two-dimensional code of the display device about the home private cloud application is scanned by using a scanning function of the WeChat, the two-dimensional code is scanned to automatically send an authorization request to the display device, and after the display device authorizes the mobile terminal, a home private cloud application applet is opened on the mobile terminal, such as the home private cloud application interface shown in fig. 8. The user can browse files stored in a hard disk of the display device through the home private cloud application interface, and select files required to be acquired from the display device on the home private cloud application interface.
After the user selects a file that needs to be retrieved from the display device, the controller of the mobile terminal may send a file loading request to the display device in response to an instruction from the user to press the "confirm" key. The file loading request includes file information selected by the user. And after receiving a file loading request sent by the mobile terminal, the controller of the display equipment sends a file corresponding to the file information to the mobile terminal through the hard disk server according to the received file information. And after receiving the file sent by the hard disk server, the mobile terminal displays the acquired file on a user interface. The user may simultaneously browse the file on the user interface of the mobile terminal while controlling the display of the file on the user interface, illustratively, controlling the size of the picture displayed on the user interface, or controlling the display of multiple pages of pictures on the user interface. Therefore, the file can be browsed or the display of the file can be controlled on the display equipment, and the file can be browsed or the display of the file can be controlled on the mobile terminal.
In the above embodiment, when the mobile terminal obtains the file corresponding to the file loading request from the display device through the hard disk server, the mobile terminal obtains the file from the hard disk through the network. Therefore, the amount of data on the hard disk acquired by the mobile terminal is limited by the network bandwidth and the forwarding performance, that is, the length of the content contained in the file acquired by the mobile terminal from the display device each time is limited by the maximum range specified by the network request. The file included in the file loading request sent by the display device to the mobile terminal may not be able to be transmitted to the mobile terminal by only one message forwarding.
In some embodiments, the display device needs to first send the total length of the file to the mobile terminal, where the total length of the file is the total length of a certain classified file stored by the display device. After the mobile terminal obtains the total length of the file, determining a file loading mode according to the size relationship between the total length of the file and the maximum file length (preset file length) transmitted to the mobile terminal by the display device once, namely the mode that the mobile terminal obtains the file from the display device, and sending the file to the mobile terminal through the hard disk server according to the determined file loading mode so as to present the corresponding file on the mobile terminal according to the corresponding file loading mode. The preset file length can be dynamically adjusted according to the maximum transmission capability supported by the software technical scheme.
In some embodiments, if the total length of the file is less than or equal to the preset file length, in this case, the file in a certain category of the display device can be completely sent to the mobile terminal through one transmission. And determining the file loading modes to be all loaded, wherein the file loading request sent by the mobile terminal to the display equipment corresponds to all files in the classification. And after receiving the file loading request, the display equipment sends all the files in the classification to the mobile terminal by using the hard disk server, and simultaneously displays all the files on the mobile terminal.
For example, after the mobile terminal is connected to the display device, a file category stored by the display device, such as a home private cloud application interface shown in fig. 8, is displayed on an interface of the mobile terminal, where the file category includes all, pictures, videos, music, documents, and collections. When the user presses the picture classification control (indicating that the user needs to view all files in the picture file classification on the mobile terminal), in response to the instruction, the mobile terminal sends a file length message acquisition request to the display device. And the display equipment receives the file length message acquisition request and sends the total length of the files classified by the pictures to the mobile terminal. And the mobile terminal receives the total length of the files classified by the pictures and determines a file loading mode according to the size relation between the total length of the files and the length of the preset files. Alternatively, the file lengths of all the classifications included in the file classification shown in fig. 8 have been sent to the mobile terminal in advance, and when the user presses the picture classification control, the mobile terminal directly determines the file loading manner according to the relationship between all the file lengths of the picture classification and the preset file length in response to the instruction.
In the embodiment of the application, all files are displayed in a list form on the mobile terminal, and presented file titles, thumbnails and the like are fixed information, so that the total length of the files in the embodiment of the application refers to the total number of the files, and the preset file length refers to the preset number of the files. For example, the number of the picture files of the picture file classification shown in fig. 8 is 200, and if the number of the files transmitted to the mobile terminal by the display device at a time is greater than 200, the mobile terminal determines that the file loading manner is completely loaded, and the generated file loading request corresponds to all the files of the picture classification. The display device receives the file loading request, the display device transmits the file to the mobile terminal once to complete all the files in the picture classification, and through single transmission, the mobile terminal can obtain all the files in the picture classification, and meanwhile, the mobile terminal can present all the files in the picture classification on a user interface.
In some embodiments, when the total length of the file exceeds the preset file length, the mobile terminal determines a file loading manner as paging loading, where the paging loading manner is specifically to generate a plurality of file loading requests, and sends the generated file loading requests to the display device in multiple times. The file corresponding to the file loading request at this time is a file with a preset file length. And simultaneously, presenting files with preset file lengths on the mobile terminal in a paging loading mode.
For example, as shown in the home private cloud application interface shown in fig. 8, when the user presses a file classification control of a video (indicating that the user needs to view all files in the video file classification on the mobile terminal), in response to the instruction, the mobile terminal sends a file length message acquisition request to the display device. And the display equipment receives the file length message acquisition request and sends the total length of the files of the video classification to the mobile terminal. And the mobile terminal receives the total length of the files classified by the pictures and judges the relation between the total length of the files and the length of the preset files. The number of video files of the video file classification shown in fig. 8 is 200, and if the number of files transmitted to the mobile terminal by the display device at a time is less than 200, the mobile terminal determines the file loading manner as page loading.
The mobile terminal generates a plurality of file loading requests according to a paging loading mode, wherein each file loading request corresponds to a file with a preset file length, and each file loading request corresponds to 20 video files exemplarily. The mobile terminal needs to receive all video files from the display device 10 times, and then needs to send a file loading request to the display device 10 times. The method for displaying the files with the preset file length on the mobile terminal in a paging loading mode is as follows: and each time 20 video files are acquired from the display device, the acquired 20 video files are presented on the user interface of the mobile terminal, and the video files which are not acquired from the display device are not displayed on the user interface of the mobile terminal. The user browses all the video files in a page-by-page browsing (browsing one page for each loaded page) manner in the above manner.
In the above embodiment, when a user views all video files in a paging browsing manner, and when the sliding position of the user is greater than the current paging position, if the user needs to continue browsing the files, the user needs to wait for the completion of loading new data, which results in poor user experience. Illustratively, the user needs to browse 200 video files shown in fig. 8, the number of files loaded on the mobile terminal at a time is 20, and the user views the video files on the mobile terminal in 10 pages in turn. When a user slides a page to the bottom end of a first page, if the user needs to browse the data of the next page continuously, the user needs to continuously receive new data from the hard disk server, and the user needs to wait for a certain time in the process, so that the paging browsing experience of the user is poor.
In order to solve the above problem, in some embodiments, the mobile terminal first sends a first file loading request to the display device, where the first file loading request corresponds to N pages of files, the length of each page of file is a preset file length, and the display device first sends the N pages of files to the mobile terminal. After the mobile terminal obtains the N pages of files, the user can browse the N pages of files on the mobile terminal. In the paging browsing process, when the page displayed by the current mobile terminal is the (N-1) th page, the mobile terminal sends a second file loading request to the display device in advance, and the second file loading request corresponds to the file of the (N + 1) th page. And the display equipment receives the second file loading request and sends the file of the (N + 1) th page to the mobile terminal through the hard disk server. When the current page displayed by the mobile terminal slides to the bottom end of the N pages, the file of the N +1 page is already loaded, so that when the current page displayed by the mobile terminal slides to the (N + 1) th page, a user can browse the file of the (N + 1) th page on the mobile terminal without waiting.
For example, the number of the video files classified by the picture file shown in fig. 8 is 200, the preset number of the video files is 20, and the 200 video files need to be divided into 10 pages and sent to the mobile terminal by the display device. The mobile terminal firstly sends a first file loading request to the display device, the first file loading request can comprise a 2-page video file, and the mobile terminal firstly obtains the 2-page video file to ensure the first browsing experience. As shown in fig. 9, when the user views from the first page at the mobile terminal and the displayed content has not slid to the bottom of the first page (to video 17 and video 18), the indication arrow that continues to slide down is not displayed at the bottom of the interface. When the user browses to the bottom end of the first page on the page of the mobile terminal, as shown in fig. 10, when the page slides to the positions of the videos 19 and 20, an indication arrow which slides downwards continuously is displayed at the bottom end of the interface, and the user is indicated to slide downwards continuously to view a video file of the next page. At this time, the mobile terminal sends a second file loading request to the display device, the second file loading request corresponds to the file of the third page, the display device sends the file of the third page to the mobile terminal through the hard disk server, the mobile terminal receives the file of the third page, and the file of the third page is preloaded when the mobile terminal browses the first page. When the user browses the third page on the page of the mobile terminal, the file of the third page can be browsed without waiting for data loading.
In some embodiments, the method of preloading described above may be repeated. Illustratively, when it is detected that the user browses to the bottom end of the second page on the page of the mobile terminal, the mobile terminal continues to send a file loading request to the display device, where the file loading request corresponds to a file of a fourth page, and the display device sends the file of the fourth page to the mobile terminal through the hard disk server. When the user browses the fourth page on the page of the mobile terminal, the file of the fourth page can be browsed without waiting for data loading. The files are presented on the mobile terminal in the preloading mode, and the experience of paging and browsing the files by a user is improved.
In some embodiments, in a paging browsing scenario, when the user has a fast sliding speed, a file is not loaded timely, which may also result in waiting for data loading during browsing. In order to solve the problem, in the paging browsing process, the mobile terminal monitors the operation speed of the current user for sliding the page of the mobile terminal, and when the operation speed is greater than a preset speed threshold, the mobile terminal sends a second file loading request to the display device in advance, wherein the second file loading request corresponds to the file of the (N + 1) th page. And the display equipment receives the second file loading request and sends the file of the (N + 1) th page to the mobile terminal through the hard disk server. When the page displayed at the current time of the mobile terminal slides to the bottom of the page N, the file of the page N +1 is loaded, so that the user can browse the file of the page N +1 on the mobile terminal without waiting when the page displayed at the current time of the mobile terminal slides to the page N + 1.
For example, the number of the video files classified by the picture file shown in fig. 8 is 200, the preset number of the video files is 20, and the 200 video files need to be divided into 10 pages and sent to the mobile terminal by the display device. The mobile terminal firstly sends a first file loading request to the display device, the first file loading request can comprise two pages of video files, and the mobile terminal firstly obtains the two pages of video files to ensure the first browsing experience. The user starts viewing from the first page at the mobile terminal. When the display device obtains that the operation speed of the user sliding the first page is larger than a preset speed threshold, the user can quickly browse the file of the mobile terminal. The mobile terminal sends a second file loading request to the display device, the second file loading request corresponds to a file of a third page, the display device sends the file of the third page to the mobile terminal through the hard disk server, and the mobile terminal receives the file of the third page and is preloaded when browsing the first page. When the user browses the third page on the page of the mobile terminal, the file of the third page can be browsed without waiting for data loading. The same is true. When the operation speed of the user sliding the second page is larger than the preset speed threshold, the mobile terminal sends a file loading request to the display device so as to request the fourth page of the file to the display device, the display device sends the fourth page of the file to the mobile terminal, and the mobile terminal loads the fourth page of the file in advance so that the user can browse the video file of the fourth page immediately when the user slides to the fourth page quickly.
As shown in fig. 9, when a file in a picture and video category is displayed on a mobile terminal, a thumbnail of the file may be displayed in the form of a list item, and the thumbnail of the corresponding file needs to be acquired from a display device. That is, the thumbnail needs to be loaded through the network before being displayed on the mobile terminal. When the data size of the thumbnail file is small, for example, only dozens of K, the occupied bandwidth resource is less, and the mobile terminal can acquire the data from the display device more quickly. However, if a thumbnail with larger file data, such as a high-definition picture, needs to be displayed, the occupied bandwidth resource is larger, and the mobile terminal cannot be quickly acquired from the display device, so that optimization of the loading mechanism of the thumbnail is also important when browsing in pages.
In order to solve the problem, the mobile terminal monitors the operation speed of a user for sliding a page on the mobile terminal, and determines the thumbnail loading time according to the operation speed and a preset speed threshold. Here, the preset speed threshold may be set by a user based on experience, or may be automatically set by the display device based on statistical data.
In some embodiments, when the user does not slide a page on the mobile terminal, that is, the current user interface of the mobile terminal stays on a certain page, the mobile terminal sends a thumbnail loading request to the display device, the display device sends a thumbnail corresponding to the thumbnail loading request to the mobile terminal through the hard disk server, and the mobile terminal completes the thumbnail loading, as shown in fig. 9, all thumbnails are presented on the mobile terminal.
In some embodiments, when the operation speed of the user for sliding the page on the mobile terminal is less than the preset speed threshold, the invisible list item is updated to be visible, and similarly, the mobile terminal sends a thumbnail loading request to the display device, the display device sends a thumbnail corresponding to the thumbnail loading request to the mobile terminal through the hard disk server, and the mobile terminal finishes loading the thumbnail, as shown in fig. 9 and fig. 10, and all thumbnails are presented on the mobile terminal.
In some embodiments, when the operation speed of the user sliding the page on the mobile terminal is greater than the preset speed threshold, that is, the user is quickly sliding the page of the mobile terminal, at this time, the user may be looking down for the file at the bottom of the list, and the file user of the middle page is not concerned, so that it is not necessary to display the thumbnail of the middle page file to the user. Therefore, the mobile terminal suspends sending the thumbnail loading request to the display device, the display device does not receive the thumbnail loading request, the mobile terminal also suspends receiving the thumbnail, and at this time, the thumbnail is also suspended from being displayed on the mobile terminal, as shown in fig. 11, the thumbnail is not displayed on each list item, and only the icon being loaded is displayed. The thumbnail loading mechanism can reduce the resource occupation of the display equipment service and the network. To distinguish between not showing thumbnails that are not currently due to network imperfections, a quick-swipe typeface may be shown on each list item.
In some embodiments, after the user slides the page on the mobile terminal rapidly, if the user stops sliding the page, the sliding speed of the page is gradually reduced until the sliding is stopped. When the sliding speed of the page is reduced to be smaller than a preset speed threshold value or the sliding is stopped, the mobile terminal continuously sends a thumbnail loading request to the display device, the thumbnail loading request corresponds to a thumbnail of a file currently displayed on the interface, the display device sends the thumbnail of the file currently displayed on the interface to the mobile terminal through the hard disk server, the mobile terminal finishes the thumbnail loading, and the loaded thumbnail is presented on the mobile terminal. Illustratively, the user starts to slide the page quickly at the first page, and if the page sliding speed is reduced to be less than a preset speed threshold value when sliding to the third page, the display device sends the thumbnail of the third page file to the mobile terminal so as to present the thumbnail on the mobile terminal.

Each file category includes a certain number of files. When a user selects a control of a certain file classification, in response to the instruction, the mobile terminal sends a file length message acquisition request to the display device, that is, the user needs to check all files in the file classification at the mobile terminal and needs to acquire the total length of all files in the file classification.
And the display equipment receives the file length message acquisition request and sends the total length of the selected file classified files to the mobile terminal. And the mobile terminal receives the total length of the files classified by the pictures and judges the relationship between the total length of the files and the length of the preset files. The mobile terminal determines a file loading mode according to the size relation between the length in the file and the length of the preset file, and generates a corresponding file loading request according to the determined file loading mode.
And if the total length of the files in the selected file classification is less than or equal to the maximum file length transmitted to the mobile terminal by the display device in a single time. Determining that the file loading mode is full loading, and generating a file loading request corresponding to all files of the file classification. And the mobile terminal sends the file loading request to the display equipment, acquires all files corresponding to the file loading request from the display equipment, and simultaneously presents all the files on the mobile terminal.
If the total length of the files in the selected file classification is larger than the maximum file length transmitted to the mobile terminal by the display device at a time, the mobile terminal determines the file loading mode as paging loading, the paging loading mode specifically generates a plurality of file loading requests, and sends the generated file loading requests to the display device in a plurality of times. The file corresponding to the file loading request at this time is a file with a preset file length. And simultaneously, presenting files with preset file lengths on the mobile terminal in a paging loading mode.
The specific process of presenting the file with the preset file length on the mobile terminal in a paging loading mode comprises the following steps:

After the mobile terminal obtains the N-page file, the user can browse the N-page file on the mobile terminal.
And in the paging browsing process, the mobile terminal monitors a UI operation signal of a user on the mobile terminal in real time. When a user slides the page on the mobile terminal to the bottom of the (N-1) th page, or when the operation speed of the user sliding the page of the mobile terminal exceeds a preset speed threshold, the mobile terminal sends a second file loading request to the display device in advance, wherein the second file loading request corresponds to the file of the (N + 1) th page. And the display equipment receives the second file loading request and sends the file of the (N + 1) th page to the mobile terminal through the hard disk server, so that the content of the (N + 1) th page is loaded by the mobile terminal in advance. When the user slides the page on the mobile terminal to the (N + 1) th page, the user can browse without waiting for loading. And repeating the process until the user browses all the files.
In some embodiments, as shown in the flow chart of the content display method shown in fig. 15, a process of displaying a thumbnail of a picture and video file on a mobile terminal in a list item:
the display equipment firstly sends the thumbnail of the home page picture or the video file to the mobile terminal so as to ensure the first browsing experience of the user. When a user browses a picture or video file on the mobile terminal, the mobile terminal monitors UI operation of the user on a display device.
When the operation speed of the user for sliding the page of the mobile terminal exceeds a preset speed threshold value, the mobile terminal pauses sending the thumbnail loading request to the display equipment, the display equipment does not receive the thumbnail loading request, the mobile terminal also pauses receiving the thumbnail, and at the moment, the thumbnail is also paused to be displayed on the mobile terminal.
When the operation speed of the user sliding the mobile terminal page does not exceed the preset speed threshold or the sliding speed is slowed to be not exceeding the preset speed threshold, whether the file of the current list item is the file visible to the mobile terminal user or not is continuously determined, if the file is not the file visible to the mobile terminal user, the mobile terminal stops sending a thumbnail loading request to the display equipment, and at the moment, the thumbnail is also stopped to be displayed on the mobile terminal. If the files are visible to the mobile terminal user, the mobile terminal sends a thumbnail loading request to the display device, the display device sends thumbnails corresponding to the thumbnail loading request to the mobile terminal through the hard disk server, the mobile terminal finishes the thumbnail loading, and all thumbnails are displayed on the mobile terminal.
