In some embodiments, the system may include a Kernel (Kernel), a command parser (shell), a file system, and an application program. The kernel, shell, and file system together make up the basic operating system structure that allows users to manage files, run programs, and use the system. After power-on, the kernel is started, kernel space is activated, hardware is abstracted, hardware parameters are initialized, and virtual memory, a scheduler, signals and interprocess communication (IPC) are operated and maintained. And after the kernel is started, loading the Shell and the user application program. The application program is compiled into machine code after being started, and a process is formed.

Referring to fig. 4, in some embodiments, the system is divided into four layers, which are an Application (Applications) layer (abbreviated as "Application layer"), an Application Framework (Application Framework) layer (abbreviated as "Framework layer"), an Android runtime (Android runtime) and system library layer (abbreviated as "system runtime library layer"), and a kernel layer from top to bottom.

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 resources in the system and obtain the services 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 (ContentProvider), 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.

Because the display device can not only provide broadcast television programs for users through digital broadcasting, but also provide richer contents and services for users based on online interactive media, internet televisions and on-demand streaming media, if the display device has a network problem, the user experience will be seriously influenced. For example, when the display device has a network problem, if the user watches a network video in a higher definition mode, a video playing may be paused, if the user downloads a file using a network, a downloading speed may be slower or a downloading failure may occur, if the user calls a friend using a video call application, a call failure or a connection failure may occur, or after the display device is turned on, the display device may not be connected to the network. Therefore, the phenomena caused by these network problems are very unfavorable for the user experience of the display device. In order to solve the network problem, a user can open a preset network detection application on the display device to perform network test, and further discover and solve the reason of the network problem. However, this approach to solving the problem is cumbersome to operate and requires the user to have a good sense of the functionality of the display device.

In order to solve the problems, the application provides a scheme for automatically monitoring the network state, so that the network problem can be found without user operation, different interface prompts can be displayed in combination with different network use scenes, the current network state condition of a user can be reminded, the user can be given appropriate suggestions, and the user experience is improved.

It should be noted that all the steps of automatically monitoring the network state provided by the present application may be written into the network detection executable program in the memory in advance, after the display device is powered on, the init process starts the network evaluation executable program, and when the executable program is run, the display device controller executes all the steps of automatically monitoring the network state. In some embodiments, after the display device is powered on, the network state is periodically detected to obtain network state information, where the network state information includes the number of devices in a network segment to which the display device belongs, a gateway response speed, a packet loss rate, and network card drive abnormality information, and the obtained network state information is used to determine whether the network state is abnormal.

In some embodiments, the display device accesses the local area network through the gateway device, and when the number of devices in the local area network is too large, problems of network disconnection, network access incapability, network slow speed due to network congestion, and the like easily occur. In order to detect the number of devices in the network segment to which the display device belongs, the controller periodically sends an Address Resolution Protocol (ARP) packet to all IP addresses included in the network segment to which the display device belongs, receives a response message returned by the device corresponding to the IP Address included in the network segment to which the display device belongs, where the response message includes a physical Address of the device corresponding to the IP Address, and further, may perform device number statistics based on the physical Address included in the received response message.

For example, assuming that the IP address of the display device is "192.168.1.1" and the subnet mask is "255.255.255.0", all the IP addresses included in the network segment to which the display device belongs are "192.168.1.1 ~ 225".

In some embodiments, the display device accesses a local area network through a gateway device. When the response speed of the gateway is slow, phenomena such as network disconnection and video playing pause easily occur. In order to detect the gateway response speed of the gateway equipment connected with the display equipment, the controller periodically sends an ARP (address resolution protocol) data packet to the gateway equipment and receives a response message returned by the gateway equipment; and determining the response speed of the gateway according to the time for sending the ARP packet and the time for receiving the response message. For example, when the controller sends an ARP packet to the gateway device, the first time is recorded, and when a response message returned by the gateway device is received, the second time is recorded, and a difference between the second time and the first time is used as a gateway response speed.

In some embodiments, the display device installed operating system comprises a Linux system. An important component of the LKM mechanism is a proc pseudo file system, which provides an interface for dynamically operating Linux kernel information for a user and is an important Linux kernel space and user space data exchange path except for system call. The/proc/net/dev is a way for the user to read or change the network adapter and the statistical information, and the controller can use the/proc/net/dev to obtain the network speed of the network card and the transceiving condition of the network packet, for example, read the packet loss rate through the/proc/net/dev file.

In some embodiments, when the wireless network card driver of the display device is abnormal, the problems of disconnection of the WIFI network, abnormal shutdown of the WIFI network, and the like can also be caused. When the wireless network card drive is abnormal, the abnormal information is automatically reported to the kernel layer, and the kernel layer transmits the abnormal information to the network detection executable program in a netlink communication mode. It is understood that the wireless network card drive exception can be divided into a recoverable exception and an unrecoverable exception, and the recoverable exception includes an exception that can be recovered without restarting and an exception that can be recovered without restarting. It should be understood that the network problems caused by unrecoverable anomalies are the most severe and most influential to the user, while the network problems caused by anomalies that can be recovered without restarting are the least minor and least influential to the user.

In the above embodiment, the device number, the gateway response speed, the packet loss rate, and the network card drive abnormality information in the network segment are dimension indexes representing the network state of the display device, and the overall quality of the network state is a result of comprehensive influence of each dimension.

In some embodiments, after the controller acquires the network state information each time, the controller obtains a dimension score corresponding to each dimension of the network state information by using a preset evaluation strategy and each dimension of the network state information, and evaluates the network state by using each dimension score. On one hand, the degree of influence of the network state information of each dimension on the overall quality of the network state can be visually reflected by the dimension score corresponding to the network state information of each dimension, on the other hand, a comprehensive score can be obtained according to the dimension score corresponding to the network state information of each dimension, and the overall quality of the network state is evaluated according to the obtained comprehensive score.

In some embodiments, a first dimension score is determined according to the number of devices in the network segment to which the device belongs, a second dimension score is determined according to the obtained gateway response speed, a third dimension score is determined according to the read packet loss rate, and a fourth dimension score is determined according to abnormal information reported by the wireless network card driver.

In an exemplary embodiment of the present application, it is preset that the maximum dimension score corresponding to each dimension network state information is 25. And determining that the first dimension scores are different according to the difference of the numerical ranges of the number of the devices in the network segment. For example, the first dimension score is 25 when the number of devices n ∈ [0,5], the first dimension score is 20 when the number of devices n [6,10], the first dimension score is 10 when the number of devices n [11,20], and the first dimension score is 5 when the number of devices n ≧ 21. According to the difference of the numerical range of the gateway response speed, the determined second dimension scores are different, for example, when the gateway response speed v is less than 1s, the second dimension score is 25, when the gateway response speed v belongs to [1s,2s ], the second dimension score is 20, when the gateway response speed v belongs to [3s,5s ], the second dimension score is 10, and when the gateway response speed v is more than or equal to 6s, the second dimension score is 5. According to the difference of the numerical range of the packet loss rate, the determined third dimension scores are different, for example, when the packet loss rate is less than 1%, the third dimension score is 25, when the packet loss rate belongs to [ 2%, 5% ], the third dimension score is 20, when the packet loss rate belongs to [ 6%, 10% ], the third dimension score is 10, and when the packet loss rate is greater than 10%, the third dimension score is 5. And determining a fourth dimension score according to whether the network card driving abnormity occurs and whether the occurred abnormity can be recovered, for example, if no abnormity exists, the fourth dimension score is 25 points, if the abnormity can be recovered without restarting, the fourth dimension score is 20 points, if the abnormity can be recovered without restarting, the fourth dimension score is 25 points, and if the abnormity can not be recovered, the fourth dimension score is 0 point.

It should be understood that the above-mentioned manner for determining the scores of the dimensions is only one possible implementation manner of the present application, and does not limit the scope of the present application.

In some embodiments, the scores of the dimensions are added to obtain a composite score of the overall quality of the network state. Illustratively, the composite score is the first dimension score + the second dimension score + the third dimension score + the fourth dimension score.

In other embodiments, each dimension index is preset with a weight, the sum of the preset weights of each dimension index is equal to 1, and the scores of each dimension are weighted and summed according to the scores of each dimension and the preset weights of each dimension index to obtain a comprehensive score of the overall quality of the network state. Illustratively, the composite score is the first dimension score × w1+ the second dimension score w2+ the third dimension score w3+ the fourth dimension score w4, where w1 to w4 respectively represent preset weights of the dimension indexes.

In some embodiments, if the overall quality of the network state is lower than the first preset value, it is determined that the network state meets the predetermined condition, and at this time, an interface prompt conforming to the current network usage scenario may be displayed in combination with the current network usage scenario. And if the comprehensive score of the overall quality of the network state is not lower than the preset value, no interface prompt needs to be displayed.

In some embodiments, in the case that the display device is connected to the network through WIFI, if the network status meets a predetermined condition, an interface prompt that meets the current network usage scenario is displayed.

For example, when the overall quality of the network state is lower than the first preset value, if the current network usage scenario is downloading data, such as downloading applications, pictures, video files, and the like, a first interface prompt is displayed in the downloading interface, where the content of the first interface prompt may be "the current network downloading speed is slow, and there is a risk of downloading failure", or "the current network downloading speed is slow, please wait for patience", and the like. If the multiple downloads fail, the user can be further prompted to 'the current network usage is larger, and the time period for downloading is recommended to be changed'.

Fig. 6 is a possible user interface, which is embodied in an exemplary download interface, shown in fig. 6, in some embodiments of the present application, in which multiple download tasks wait for downloading, the download speed of the downloading task is slow, and a first interface prompt is displayed on the download interface, where the content is "the current network download speed is slow, and there may be a risk of download failure".

For example, when the overall quality of the network state is lower than the first preset value, if the current network usage scenario is to play a network video, a second interface prompt is displayed on the play interface, and the prompt content of the second interface may be "the current network state is not good, please cache for a period of time to watch". For another example, when the network state meets the predetermined condition, if the current network usage scenario is to play the network video, it is determined whether the definition mode of playing the network video is the mode with the lowest definition, if so, an interface prompt is displayed on the top layer of the user interface, the content may be "the current network state is not good, please cache for a period of time to watch again", if not, an interface prompt is displayed on the top layer of the user interface, the content may be "the current network state is not good, please switch to the lower definition mode".

Fig. 7 is a possible user interface shown in some embodiments of the present application, which is specifically an exemplary playing interface, as shown in fig. 7, a network video played on the playing interface has a pause phenomenon, and a second interface prompt is displayed on an upper layer of the playing interface, where the content of the second interface prompt is "current network state is not good, please buffer for a period of time and watch again".

In some embodiments, if the dimension score corresponding to the one-dimension network state information is lower than a preset value, it is determined that the network state meets a preset condition, and at this time, an interface prompt conforming to the current network use scene is displayed.

For example, if the dimensionality score corresponding to the packet loss rate is lower than the second preset value, it is determined whether the current network usage scene is a download scene, if so, a first interface prompt is displayed on the download interface, and the content of the first interface prompt may be "the current network download speed is slow, and there may be a risk of download failure", as shown in fig. 6, or "the current network download speed is slow, please wait for patience", and the like. If the multiple downloads fail, the user can be further prompted to 'the current network usage is larger, and the time period for downloading is recommended to be changed'. In other embodiments, if the composite score is lower than a first preset value and the dimensional score corresponding to the packet loss rate is lower than a second preset value, if the current network usage scenario is a download scenario, the first interface prompt is displayed on a download interface.

If the dimension score corresponding to the gateway response speed is lower than the third preset value, it is determined whether the current network usage scene is the network video playing scene, if so, a second interface prompt is displayed on the playing interface, and the content of the second interface prompt may be "current network state is not good, please cache for a period of time and watch again", as shown in fig. 7. In other embodiments, if the composite score is lower than the first preset value and the dimension score corresponding to the gateway response speed is lower than a third preset value, if the current network usage scene is a network video playing scene, the second interface prompt is displayed on the playing interface.

In some embodiments, if the dimension score corresponding to the number of devices in the network segment to which the display device belongs meets a predetermined range, an interface prompt for prompting a user to disconnect some devices accessing the network to avoid network congestion is displayed in a currently displayed user interface, and the content of the interface prompt may be "a router connects too many devices, please disconnect some devices to try again". The currently displayed user interface may be the user interface shown in fig. 6 or fig. 7.

In some embodiments, after the network state evaluation is completed, the controller records the network state information of each dimension, the corresponding dimension score and the comprehensive score into a designated log file, stores the designated log file locally, and uploads the designated log file to the server.

In some embodiments, when the display device cannot be connected to a network or cannot be reconnected after the network is disconnected, the state information, the score and the comprehensive score of each dimension network, which are obtained last time, are read from a designated log file stored locally, the reason why the network cannot be connected is analyzed according to the state information, the score and the comprehensive score of each dimension network, and an interface prompt is displayed according to the analyzed reason. For example, if the fourth dimension score is 0 score, that is, the dimension score corresponding to the driving condition of the wireless network card is 0 score, that is, the wireless network card drive has an abnormality that cannot be recovered by restarting, the content prompted by the display interface may be "there may be a problem in the television network, and please actively make an after-market call to obtain help"; if the first dimension score is only 5 points, that is, the dimension score corresponding to the number of the devices in the network segment is 5 points, that is, the number of the devices in the network segment is too large, the content prompted by the display interface may be "the router has connected too many devices, please disconnect some devices and try again".

Fig. 8 illustrates a possible user interface in some embodiments of the present application, which is a system homepage displayed when the display device cannot connect to the network, and as shown in fig. 8, an interface prompt with content "there may be a problem in the tv network and please actively make an after-sales call to get help" is displayed on the upper layer of the system homepage.

Fig. 9 is a possible user interface shown in some embodiments of the present application, which is specifically a WIFI setting interface displayed when a display device cannot be connected to a network, and as shown in fig. 9, an interface prompt with the content "a router has connected too many devices and please disconnect some devices and try again" is displayed on the upper layer of the system homepage.
