In some embodiments, at least one application program runs in the application program layer, and the application programs can be Window (Window) programs carried by an operating system, system setting programs, clock programs, camera applications and the like; or may be an application developed by a third party developer such as a hi program, a karaoke program, a magic mirror program, or the like. In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resource in the system and obtain the service of the system in execution through the API interface

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window processes, such as obtaining a display size, determining whether a status bar is available, locking a screen, intercepting a screen, controlling a display change (e.g., zooming out, dithering, distorting, etc.) and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display drive, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor, etc.), and so on.

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. 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 some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of the cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

NAS (Network Attached Storage) is a dedicated data Storage server, and can provide a cross-platform file sharing function. Based on the NAS function, the file of the mobile terminal can be transmitted to the display device across the network. The whole process of file transfer is actually divided into two stages: uploading files and downloading files. In the process that the mobile terminal uploads the file to the server, a user at the display device end cannot know the uploading progress, and in the process that the display device downloads the file from the server, the user at the mobile terminal cannot know the downloading progress, so that the use experience of the user is poor.

In order to solve the above problem, an embodiment of the present application provides a file transfer system, as shown in fig. 6, which is a schematic diagram of a file transfer system framework, where the file transfer system shown in fig. 6 includes a mobile terminal and a display device. The file in the mobile terminal is transferred to the NAS hard disk through the network, and the file transfer system shown in fig. 6 transfers file data based on the wide area network. The NAS hard disk can be integrated in the display equipment, and can also be used as external equipment connected with the display equipment.

Specifically, the process of uploading a file to the server by the mobile terminal 100A is as follows: the mobile terminal can share the file to the display device through the file sharing application. For example, as shown in fig. 7, the user interface in the mobile terminal is a picture display interface, a sharing icon control is disposed at a lower right corner of the picture display interface, in the user interface shown in fig. 7, the controller receives an instruction input by a user to select the sharing icon control, and in response to the instruction, as shown in fig. 8, a sharing bar is displayed on the picture display interface in an overlapping manner. The sharing bar comprises a plurality of application icon controls for sharing and a plurality of operation character controls.

In the user interface shown in fig. 8, the controller receives a user input selecting a "home private cloud" application icon control, and in response to the instruction, jumps from the user interface shown in fig. 8 to the home private cloud application interface shown in fig. 9. The home private cloud application interface shown in fig. 9 includes a "share to home private cloud" text control, and the controller receives an instruction input by a user to select the "share to home private cloud" text control, and in response to the instruction, jumps from the home private cloud application interface shown in fig. 9 to the select device interface shown in fig. 10.

The select device interface shown in FIG. 10 includes a plurality of device controls: a "living room television" device control and a "bedroom television" device control. In the interface for selecting devices shown in fig. 10, the controller receives an instruction for selecting a "living room television" device control input by a user, and in response to the instruction, uploads a picture currently displayed by the display interface to a living room television corresponding to the "living room television" device control. Specifically, the mobile terminal uploads the picture to the display device in the living room through the ESS server, and during the uploading process, as shown in the mobile terminal sending interface shown in fig. 11, the display displays an uploading progress bar, an "sending" uploading prompt and a "cancel" control. In the process that the mobile terminal uploads the picture to the display device, the picture can be further cancelled by selecting the cancel control.

In some embodiments, as shown in fig. 12, a two-dimensional code of a display device for a home private cloud application may be scanned using a sweep function of WeChat to open a home private cloud application applet on a mobile terminal, such as the gather-look applet application interface shown in fig. 13. The application interface includes "photos and videos" and "WeChat" controls, as well as a prompt "select a type of file desired to be uploaded". Here, uploading a file to the display device through the mobile terminal requires connecting the mobile terminal and the display device to the same WI-FI or hotspot. As shown in fig. 14, if the mobile terminal is not connected with WI-FI, a prompt is displayed on the user interface: please first go to setup-wireless lan-connect WI-FI or setup-personal hotspot-open hotspot. After the user has set the prompts, the controller receives a user-entered command to select the "click refresh" control, and in response to the command, if the refresh is successful, jumps back from the user interface shown in FIG. 14 to the user interface shown in FIG. 13.

In the user interface shown in FIG. 13, the controller receives an instruction from the user to select the photo and video "control, and in response to the instruction, jumps from the user interface shown in FIG. 13 to the file presentation interface shown in FIG. 15. The file display interface shown in fig. 15 includes a plurality of picture files and video files, and check boxes are provided at upper right corners of the picture files and the video files.

In the file presentation interface shown in fig. 15, the controller receives a user-input instruction to select a check box of a picture file or a check box of a video file, and in response to the instruction, fills the selected check boxes with numerals that index the check boxes in the user-selection order. When the number of the pictures and videos selected by the user reaches 9, as shown in the file display interface shown in fig. 16, the unselected pictures and videos are displayed in gray, and the selected pictures and videos are highlighted. In the file presentation interface shown in fig. 16, the controller receives an instruction of selecting the completion control input by the user, and jumps from the file presentation interface shown in fig. 16 to the user interface of fig. 17 in response to the instruction. In the user interface shown in fig. 17, a transmission progress bar showing the progress of transmission of the file data determined according to the signal to transmit the file data and a cue "uploading" are displayed.

Fig. 6 shows a specific process of uploading file data to the server 400 by the mobile terminal 100A, after the file data is completely uploaded to the server 400, the hard disk service 500(NASService) acquires the stored file data from the server 400, the hard disk server 500 sends the acquired file data to the hard disk 600, and sends the file data to the preset application 700, so that the received file data can be displayed to the user through the preset application 700.

In some embodiments, in order to simultaneously show an upload progress of file data transmission from the mobile terminal to the server and a download progress of file data transmission from the server to the display device at the mobile terminal and the display device, the server 400 includes a data server 400A for transmitting the file data and a message server 400B for transmitting the progress. Illustratively, the Server 400A is an ESS Server (Enterprise Storage Server). Server 400B is an MQTT server (Message Queuing telemetering Transport).

The traditional file remote transmission scheme is as follows: first, a P2P (Peer-to-Peer) connection is tried between the devices, and if the P2P connection is successfully established between the devices, the files are directly transmitted point to point. The traditional file remote transmission scheme is based on the stability of P2P connection, and the forwarding function can not meet the management requirement on user accounts, the security can not be ensured, and the file content of users can not be managed and controlled. According to the file remote transmission method and device, the ESS server is used for transmitting file data, and meanwhile the MQTT server is used for transmitting progress messages, so that the problems existing in the traditional file remote transmission scheme can be solved. The data server 400A and the message server 400B may be servers having both a function of transmitting data and a function of transmitting messages as a whole. The data server 400A and the message server 400B may be servers that are separately provided. The data server 400A and the message server 400B may be integrated in the display device, or may be separate devices that are connected to the display device via a local area network or a wide area network.

Specifically, the mobile terminal 100A uploads the file data to the ESS server 400A while updating the upload schedule in real time on the user interface of the mobile terminal 100A, such as the schedule bar shown in fig. 11. At this time, the display device 200 cannot sense the progress of the mobile terminal 100A in uploading the file data to the ESS server. The mobile terminal 100A periodically sends the uploading progress from the MQTT server 400B to the hard disk service 500, and the hard disk service 500 sends the received uploading progress to the preset application 700, so that the preset application 700 presents the uploading progress on the user interface of the display device 200.

After the mobile terminal 100A completely uploads the file data to the ESS server 400A, a prompt indicating that the uploading stage is completed may be presented on the user interface of the mobile terminal 100A, and a prompt indicating that the uploading stage is completed may also be presented on the user interface of the display device according to the above transmission process. The hard disk service 500 downloads the uploaded file data from the ESS server 400A, and the hard disk service 500 transmits the file data to the hard disk 600 for storage and transmits the file data to the preset application 700 to display the file data, for example, a thumbnail image of a picture or a video on a user interface. The preset application 700 and the hard disk service 500 are used as two processes, and are bound by an aid id (Android Interface Definition Language), so as to implement cross-process communication. Illustratively, as shown in the user interface of fig. 18, the preset application 700 is a home private cloud application, and after downloading a video from the ESS server 400A, the hard disk service 500 sends the video to the home private cloud application, and displays a thumbnail image of the video on the user interface.

While the hard disk service 500 downloads the file data from the ESS server 400A, the download progress is displayed on the user interface, such as the progress display box in the upper right corner of the user interface shown in fig. 18. In the process of downloading the file data from the ESS server by the display device, the mobile terminal 100A cannot sense the downloading progress, the hard disk service 500 periodically transmits the downloading progress to the MQTT server, and the MQTT server transmits the downloading progress to the mobile terminal 100A. The mobile terminal 100A also has only a preset application therein, and an exemplary built-in home private cloud application, and displays the download progress on the user interface through the home private cloud application.

In the above embodiment, the whole file transmission process is actually divided into two stages, the flow rate of the file size generated in the whole process is twice the size of the source file, and in order to show the actual transmission progress information data to the user, the progress information data finally shown to the user in the embodiment of the present application is the calculated progress information data.

Illustratively, the total file size is 100M, the traffic generated by the process of uploading the file data to the ESS server 400A by the mobile terminal 100A is 100M, the traffic generated by the process of downloading the file data from the ESS server 400A by the hard disk service 500 is 100M, and the actual file size actually displayed to the user is 100M, that is, the progress of the uploading stage and the downloading stage only accounts for 50% of the total progress, so that neither the mobile terminal 100A nor the display device 200 can show progress according to the actual file size.

The progress calculation formula when the mobile terminal 100A uploads 100M file data to the ESS server 400A is as follows: and pro/(2T), where U represents the size of the file data uploaded by the mobile terminal to ESS server 400A in real time, and T represents the total size of the file data. Assuming that the size of the file data uploaded to the ESS server 400A by the mobile terminal 100A at a certain time is 20M, the uploading progress of the file data is 20/2 × 100 ═ 10%.

During the process of uploading the file data to the ESS server 400A, the mobile terminal 100A updates the uploading schedule presented on the user interface in real time, and periodically uploads the uploading schedule to the hard disk service 500 through the MQTT server 400B. For example, the mobile terminal 100A may upload the current updated upload schedule to the MQTT server 400B every 2S according to a preset period, and the MQTT server 400B then sends the upload schedule to the hard disk service 500, and the hard disk server 500 sends the upload schedule to a preset application, so that the upload degree is displayed on the user interface of the display device 200.

The mobile terminal 100A transmits basic information of a file while transmitting file data to the display device 200, and displays the basic information and a notification message on a user interface. Illustratively, as shown in fig. 18, the basic information and the notification message are displayed in the upper right corner of the user interface, at which time it may be prompted for the mobile terminal 100A to be transferring a file to the display device 200. The notification message further includes a prompt for displaying a detailed list, which is illustratively viewed by pressing a menu key, as shown in fig. 8. The prompt is used to view a detailed list of files being transferred by pressing a menu key.

In some embodiments, the display device 200 updates the download progress in real-time on the display device 200 user interface during the download of file data from ESS server 400A. When the display device 200 downloads 100M file data from the ESS server 400A, the file transmission progress calculation formula is: pro is U/(2T) + D/(2T), where U is 100M and D represents the size of the file that the display device 200 has downloaded from the ESS server 400A. Illustratively, the file transmission progress of the display device 200 at a time when 40M file data is downloaded from ESS server 400A is 100/(2 x 100) +40/(2 x 100) 70%. The hard disk service 500 transmits the calculated transmission progress to the MQTT server 400B, and the MQTT server 400B transmits the acquired transmission progress to the mobile terminal 100A, so that the calculated transmission progress is displayed on the user interface of the mobile terminal 100A.

In some embodiments, when hard disk service 500 downloads the completed file data from ESS server 400A, then the entire file upload process is complete. The hard disk service 500 sends the download completion message to the preset application 700 and the MQTT server 400B, respectively, and the MQTT server 400B forwards the download completion message to the mobile terminal 100A, and displays the download completion message on the user interface of the display device and the user interface of the mobile terminal 100A. Illustratively, as the user interface of the mobile terminal shown in fig. 19, a prompt message "sent, you can view in the home private cloud" is displayed on the user interface of the mobile terminal.

In some embodiments, the file data in the mobile terminal can also be transmitted to the display device accessing the hard disk through the local area network. Specifically, the mobile terminal sends a file and an uploading progress to the hard disk service through an HTTP server built in the display device. And the hard disk service sends the uploading progress to the preset application, so that the uploading progress is displayed in the preset application. Because the mobile terminal directly transmits the file data to the hard disk, the flow generated in the whole process is the total size of the file.

File transmission and message transmission both depend on the stability of a network and a server, so that factors such as network abnormity or message loss may occur in the file transmission process, and the situation that a mobile terminal or display equipment cannot acquire files or messages in time occurs, thereby causing progress updating abnormity.

In order to solve the above problem, in some embodiments, when the mobile terminal starts to upload file data to the display device, both the mobile terminal and the display device start a data update detection thread, and specifically create and maintain a data table of progress information. The data table records the file name, size and transmission progress (display device maintains an upload schedule, and the mobile terminal maintains a download schedule). When the uploading progress is periodically obtained by the display equipment, correspondingly updating the uploading progress; and when the mobile terminal periodically obtains the downloading progress, correspondingly updating the downloading progress. When the uploading schedule is not updated by the display device or the downloading schedule is not updated by the mobile terminal after the preset time is exceeded, the file transmission failure can be judged.

Illustratively, when the mobile terminal uploads a file to the ESS server, the uploading progress is updated in real time, and the uploading progress is periodically sent to the hard disk service through the MQTT server. And when each uploading progress is received, the hard disk service marks the receiving time. The detection thread may detect whether a new upload schedule is received according to a preset time, for example, every 1 minute according to the marked receiving time. If no new upload schedule is detected at an interval of 1 minute (the upload schedule time of the upload schedule is not updated), it is judged that the file transfer has failed.

When the display equipment downloads the file from the ESS server, the downloading progress is updated in real time, and meanwhile, the downloading progress is periodically sent to the mobile terminal through the MQTT server. The mobile terminal also marks the receiving time when receiving each piece of downloading progress. And the detection thread detects whether a new downloading progress is received every 1 minute according to the marked receiving time. If no new download progress is detected at 1 minute intervals (the download progress time of the download schedule is not updated), a transmission failure is determined. And after the transmission failure is judged, displaying the transmission failure result on both the user interface of the mobile terminal and the user interface of the display equipment. Illustratively, as the user interface of the mobile terminal shown in fig. 20, a prompt message "failure to send, failure to upload picture" is displayed on the user interface of the mobile terminal.

In some embodiments, when the number of the files uploaded to the display device by the mobile terminal is 1, the transmission progress of the files calculates the proportion of the size of the transmitted files of a single file to the total size. Illustratively, the total size of a single file is 100M, the size of the file uploaded to the hard disk service by the mobile terminal is 30M, the uploading progress is 30/2 x 100-15%, and the transmission progress is 30%. The file size of the hard disk service downloaded from the ESS server is 20M, the download progress is 20/2 × 100 ═ 10%, and the transmission progress is 50% + 10% + 60%.

When the number of the files uploaded to the display device by the mobile terminal is larger than 1, the transmission progress of the files is calculated by the proportion of the number of the transmitted files in the total number of the files. Illustratively, the number of files to be uploaded is 10, the number of files uploaded to the hard disk service by the mobile terminal is 6, and the uploading schedule is 6/10-2-30%, and the transmission schedule is 60%. If the number of files downloaded by the hard disk service from the ESS server is 5, the download progress is 5/10 × 2, which is 25%, and the transmission progress is 50% + 25% + 75%.

An embodiment of the present application provides a file transmission progress display method, such as a signaling diagram of the file transmission progress display method shown in fig. 21, where the method includes the following steps:

step one, in the process that a mobile terminal uploads file data to an ESS server, the mobile terminal calculates transmission progress according to a signal of the uploaded file data, the transmission progress is the uploading progress at the stage, and the mobile terminal sends the transmission progress to display equipment through an MQTT server so that the transmission progress is presented on the mobile terminal and the display equipment at the same time;

and step two, during the process that the display equipment downloads the file data from the ESS server, the display equipment calculates the transmission progress according to the signal of the downloaded file data, the transmission progress at this stage is the sum of the uploading progress and the downloading progress when the mobile terminal uploads the file data to the server, and the display equipment sends the transmission progress to the mobile terminal through the MQTT server so as to simultaneously present the transmission progress on the mobile terminal and the display equipment.
