FIGS. 2A-2G exemplarily show schematic diagrams of a GUI 400 provided by the display device 200 by operating the control device 100.

As shown in FIG. 2A, the display device displays a webpage main page 41 on the display, which may be a video playback page of a video website. The webpage main page 41 shown in FIG. 2A includes a video playback area, a webpage option area, and a video details area. Among them, the video playback area includes a video playback screen, and the bottom of the video playback screen is provided with a progress bar, a pause playback icon, and a fast forward icon. A video screen is being played in the video playback area of FIG. 2A. In the related art, if the user wants to fast forward or rewind the video, he needs to place the virtual mouse on the progress bar and move the progress bar to realize fast forward or rewind. If the user wants to pause or play the video, he needs to move the virtual mouse to the pause icon and click the pause icon to pause the video. The size of the progress bar and icon is relatively small on the main page of the web page. By moving the virtual mouse to the progress bar or icon, the expected video playback control operation can be realized, which is difficult to operate.

In FIG. 2A, when the user presses the pause button on the control device, as shown in FIG. 2B, the display device responds to the command input by the button to control the pause of the current video, and directly controls the pause of the current video without moving the virtual mouse. On the pause icon, the user does not need to make the next click operation, and the pause operation can be realized. When the current video is paused, a pause instruction icon will be superimposed on the current video screen.

In Figure 2B, when the user presses the play button on the control device, as shown in Figure 2A, the display device responds to the instruction input by the button to control the current video to start playing, and directly controls the current video to start playing without moving the virtual mouse On the play icon, the user does not need to make the next click operation to start the play operation. When starting to play the current video, the pause indicator icon previously displayed on the current video screen disappears.

In Figure 2A, when the user presses the fast forward button on the control device, as shown in Figure 2C, the display device responds to the command input by the button to control the fast forward of the current video and directly controls the fast forward playback of the current video. At the same time, a fast-forward playback indicator icon is superimposed on the current video screen. After releasing the fast-forward button, as shown in Figure 2D, the fast-forward playback indication icon on the video screen disappears, and the current playback progress is fast-forwarded from 10 minutes and 50 seconds to 11 minutes and 10 seconds.

In Figure 2A, when the user presses the fast-rewind button on the control device, as shown in Figure 2E, the display device directly controls the fast-rewind playback of the current video in response to the command input by the button to control the fast-rewind of the current video. At the same time, the fast-reverse playback indicator icon is superimposed on the current video screen. After releasing the fast-rewind button, as shown in Figure 2F, the fast-rewind playback indication icon on the video screen disappears, and the current playback progress fast-rewinds from 10 minutes and 50 seconds to 10 minutes and 30 seconds.

In some embodiments, the main web page 41 may also be a non-video playback page, for example, it may be a detailed introduction page of a certain video as shown in FIG. 2G. The main page of the webpage shown in FIG. 2G does not include video images. In Figure 2G, when the user presses any one of the pause button, start button, fast forward button, fast reverse button and other buttons on the control device that selects the playback control function, since the current main page does not include video images, the display device ignores the user Video playback control instructions input by pressing the above keys.

The implementation logic principle of the video playback control method of the foregoing embodiment is as follows:

When the browser loads a webpage, a JavaScript-based Player Controller (play control) module can be injected into the loaded webpage through plug-in mechanisms such as NPAPI/PPAPI. The Player Controller module registers a callback interface to the browser core and calls back through this The interface receives messages from the underlying system to the Player Controller module through the browser kernel. Among them, the function of the Player Controller module is to control the playback of the video in the webpage through the interface of the standard HTML5 VIDEO control. The messages that the Player Controller module pays attention to can be play, pause, play pause, stop, backwards, forwards, and so on.

As shown in FIG. 3A, the browser webpage is loaded and the Player Controller module is initialized at the same time. When the browser is started, the webpage is loaded through the browser startup module, and then the loaded webpage is parsed by the browser parsing module, and the Player Controller module is loaded at the same time. After the webpage is parsed, the browser rendering module renders the webpage, and displays the webpage after rendering. At the same time, the Player Controller module callbacks the registration message to the browser message processing module.

The schematic diagram of the logic principle of the video playback control method shown in FIG. 3B. The button receiving module obtains the video playback pause control instruction corresponding to the play pause button input by the user by pressing the play pause button on the control device, and sends the video playback pause control instruction to the command analysis module. Here, because the key receiving module may receive different playback control commands, including at least one of a playback command, a pause command, a playback pause command, a stop command, a rewind command, and a fast forward command. The command analysis module can analyze these instructions and generate corresponding messages.

Following the foregoing embodiment, the command analysis module analyzes the video pause control instruction and converts it into a play pause message. And send the play pause message to the browser message processing module, and finally call back to the Player Controller module. Specifically, the play pause message is sent to the browser kernel through the browser receiving message interface. The Player Controller module obtains the play pause message through the callback interface of the browser kernel. The Player Controller module controls the playback of the video elements in the current webpage according to the play pause message.

Here, the control device sets the play pause function on the same button, and what the Player Controller module obtains is a play pause message. It is necessary to analyze the play pause message according to the state of the video element in the current webpage, and then perform the corresponding broadcast control operation on the video element. If the video element in the current webpage is in the playing state, the Player Controller module controls the video element in the current webpage to pause playing according to the play pause message. If the video element in the current webpage is in the paused playback state, the Player Controller module controls the playback of the video element in the current webpage according to the play pause message.

As shown in FIG. 3C, a schematic diagram of the logic principle of another video playback control method is realized. The button receiving module obtains the video playback fast-forward control instruction corresponding to the Forwards button input by the user by pressing the Forwards button on the control device, and sends the video playback fast-forward control instruction to the command analysis module. The command analysis module analyzes the video fast-forward control command and converts it into a Forwards message. And send the Forwards message to the browser message processing module, and finally call back to the Player Controller module. Specifically, the Forwards message is sent to the browser kernel through the browser receiving message interface. The Player Controller module obtains the Forwards message through the callback interface of the browser kernel. The Player Controller module controls the fast forward of the video elements in the current webpage according to the Forwards message.

In some embodiments, when the browser injects the Player Controller module, the Player Controller module will initialize and obtain the non-hidden video tags in the current webpage. If there is a non-hidden video tag in the current webpage, the video element corresponding to the video tag is saved to the Player Controller module. If there is no non-hidden video tag in the current webpage, the Player Controller module will get empty. When the Player Controller module receives the play pause message, it will first determine whether the Player Controller module saves video elements. If a video element is stored in the Player Controller module, control the video element to pause playback. If there are no video elements stored in the Player Controller module, the processing of the pause message will be skipped. If there are no video elements stored in the Player Controller module, it means that the current web page currently has no actions related to video playback, for example, there is no video screen in a text-only web page.

Here, since the content contained in the webpage may change over time (for example, the current webpage has no action related to video playback at a certain moment, and there are actions related to video playback after the user refreshes the webpage), so every time the user When the video playback control related buttons on the control device are pressed, the Player Controller module needs to obtain the non-hidden video tags in the current webpage again.

In the above embodiment, the video playback control instruction corresponding to the button input by the user by pressing the button on the control device is acquired, and the playback of the video element in the current webpage is controlled according to the video playback control instruction. When the user needs to control the video playback in the webpage, there is no need to move the focus to the control. Only by pressing the corresponding video playback control button on the control device, the expected video playback control effect can be realized, the operation is simple, and the user's experience in video playback control is improved.

4A-4B exemplarily show a flowchart of a method for controlling video playback.

In combination with the method in FIG. 4A, the method includes the following steps S51 to S54:

Step S51: Display a web page on the display, the web page contains multiple web controls;

Step S52: Receive user input by pressing a button on the control device; for example, as shown in FIG. 1E, the control device 100 configured to control the display device 200 is implemented as a remote controller, which includes a pause button for selecting a playback control function , Start button, fast forward button, fast reverse button, etc. For example, in FIG. 2A, when the user presses the pause button on the control device, an instruction to pause the video playback corresponding to the pause button input by the user by pressing the pause button on the control device is obtained.

Step S53: When recognizing that the key input is an instruction to instruct the selector to select the first broadcast control control among a plurality of web page controls, perform a first operation corresponding to the first broadcast control control; the first broadcast control control Used to indicate and control web video broadcast control;

Step S54: When it is recognized that the key input is an instruction to perform the first operation, if it is determined that the web page contains a web page video, perform the first operation for controlling the web page video broadcast control.

Following the above-mentioned embodiment, as shown in Fig. 2B, the display device directly controls the current video to be paused in response to the command input by the button to control the pause of the current video, without the need to move the virtual mouse to the pause icon, and the user does not need to do it. After the next click operation, the pause operation can be realized. When the current video is paused, a pause instruction icon will be superimposed on the current video screen.

With reference to the method in FIG. 4B, the method includes the following steps:

S61: Display a web page on the display, where the web page includes multiple web controls;

S62: Receive user input by pressing keys on the control device; for example, as shown in FIG. Start button, fast forward button, fast reverse button, etc. For example, in Fig. 2A, when the user presses the pause button on the control device, the command to pause the video playback corresponding to the pause button input by the user by pressing the pause button on the control device is obtained.

S63: Identify the instruction corresponding to the key input;

S64: When it is recognized that the key input is an instruction to perform an operation, if it is determined that the web page contains a web page video, and the current state of the web page video is determined, execute the control for controlling the web page video broadcast and the Target operations with different current states.

For example, as shown in FIG. 3B, the schematic diagram of the logic principle of the video playback control method is realized. The button receiving module obtains the video playback pause control instruction corresponding to the play pause button input by the user by pressing the play pause button on the control device, and sends the video playback pause control instruction to the command analysis module. The command analysis module analyzes the video pause control instruction and converts it into a play pause message. And send the play pause message to the browser message processing module, and finally call back to the Player Controller module. Specifically, the play pause message is sent to the browser kernel through the browser receiving message interface. The Player Controller module obtains the play pause message through the callback interface of the browser kernel. The Player Controller module controls the playback of the video elements in the current webpage according to the play pause message.

Here, the control device sets the play pause function on the same button, and what the Player Controller module obtains is a play pause message. It is necessary to analyze the play pause message according to the state of the video element in the current webpage, and then perform the corresponding broadcast control operation on the video element. If the video element in the current webpage is in the playing state, the Player Controller module controls the video element in the current webpage to pause playing according to the play pause message. If the video element in the current webpage is in the paused playback state, the Player Controller module controls the playback of the video element in the current webpage according to the play pause message.

In some embodiments, if the key input is recognized as an instruction to perform a fast forward operation, if it is determined that the web page contains a web page video, and if it is determined that the web page video is in a playing state, the control can be controlled according to the fast forward instruction Fast forward web video. If it is recognized that the key input is an instruction to perform a rewind operation, if it is determined that the web page contains a web video, and it is determined that the web video is in a playing state, the web video can be controlled to rewind according to the fast forward instruction.

In the display device, some built-in applications are preset, and the built-in applications do not depend on the network. When the device is not connected to the network, the user can open the application and view related information and resources in the application. In some application scenarios, smart TVs generally have built-in electronic manual (E-manual) applications, that is, operation guides, and some graphical user interfaces that prompt and guide users to operate are preset in the E-manual application, and HTML is loaded through the browser The contents of the operation guide are displayed in the form of page data or PDF format files. This application mainly aims at the problems existing when the display device displays the operation guide, and provides corresponding solutions.

Click on the E-manual application icon, or open the E-manual application through the Settings portal. Figure 5 exemplarily shows the main page displayed when the operation guide is opened. The main page may include "LiveTV" (LiveTV), "Connection", "Multi_screen", "Smart Functions", "Picture and Sound", "Accessibility and System", "Solving Problems" (Troubleshooting) and "Using the E-manual" (Using the E-manual) and other sub-page options, when the display device is not connected to the network, each page of the E-manual application (including the main page and each sub-page) does not display two-dimensional Code, that is, when the user is not connected to the Internet, the user only sees the information resources preset in the operation guide, which are inherent information resources of the operation guide pre-stored in the display device, and these information resources cannot be changed and updated.

When the operation guide is opened, the connection status of the display device is detected. If the connection status is detected as the network is connected, the URL request corresponding to the operation guide is sent to the server, and the server obtains the latest operation guide of the display device according to the URL request Content, and send the corresponding QR code URL; the display device generates the QR code after receiving the URL, as shown in Figure 6, the operation guide needs to refresh the page of the E-manual application under the network.

The refreshed page will display the generated QR code. In order to avoid affecting the user’s browsing due to the QR code occluding the page, a thumbnail of the QR code can be displayed at the specified location of the page. Refer to the page shown in Figure 7, the specified location is In the upper right corner of the page, the thumbnail of the QR code reduced by a certain multiple is displayed in the upper right corner of the page. The thumbnail of the QR code can be regarded as the QR code identification and the entrance to push the operation guide to the terminal device. Go to the two-dimensional code identification to know that the two-dimensional code can be scanned by the terminal device to view the latest operation guide content in the terminal device. At this time, the operation guide displayed by the terminal device includes the full content of the main page and sub-pages. The terminal device described in this application may be a smart phone, a tablet, or other electronic devices with a QR code scanning function, and the terminal device may support systems such as IOS and Android.

The thumbnail of the QR code can not only be displayed on the main page of the operation guide. After the user clicks to enter each sub-page, the sub-page must also display the thumbnail of the QR code at the specified location, so that the user opens the operation guide Any page can scan the QR code at any time. As shown in Figure 8, taking "Real-time TV" as an example, click the "Real-time TV" option on the main page to enter the "Real-time TV" sub-page. The left side of the "Real-time TV" sub-page displays channel search, channel editing, and channel List and other options. After clicking any option on the left side of the sub-page, the corresponding information resources will be displayed on the left side of the sub-page. These information resources can be displayed to users in the form of text, images, tables, lists, etc., displayed in the upper right corner of the sub-page The thumbnail of the QR code. It should be noted that the QR code logo in this embodiment is visually presented in the form of a thumbnail. Of course, in actual applications, the QR code logo can be in other forms, such as text display. "Scan the QR code" is not limited in the embodiment of this application.

After seeing the thumbnail/logo of the QR code, the user can click the thumbnail/logo of the QR code by remote control or touch control, as shown in Figure 9, after the thumbnail of the QR code is clicked, it will An enlarged view of the QR code is displayed on the upper level of the current page. Below the enlarged view of the QR code can be configured prompt information to guide the user to operate. For example, the prompt message in Figure 9 is "Please use your terminal to scan the QR code, that is The operation guide can be displayed on the terminal, and the prompt information can be adaptively set according to the actual application. The user uses the QR code scanning function in the terminal device, such as using the "scan" of the WeChat and other applications to scan the QR code. Refer to Figure 10, and the scanning area is aligned with the QR code, and the terminal device can automatically scan And recognize the QR code, and then display the latest content of the pushed operation guide (that is, the online operation guide) in the content area of the terminal device; if the shooting environment is dark, you can click "Tap to illuminate". Turn on the flash and increase the illumination to ensure that the QR code can be recognized. As shown in Figure 11. It should be noted that the display form of the operation guide in the terminal is not limited, and the page settings, layout, and resource display of the operation guide should be subject to the actual application.

After the user successfully scans the QR code, in order to make the enlarged image of the QR code no longer cover the application page, it is necessary to hide the enlarged image of the QR code so that the QR code is displayed as a thumbnail again. At this time, the user can Click the enlarged image of the QR code to hide the enlarged image of the QR code. This method is mainly based on the user’s manual operation; or the terminal device automatically generates the scanned instruction information in response to the successful scanning of the QR code, and The scanned instruction information is sent to the display device. After the display device receives the scanned instruction information, it can control to hide the enlarged view of the QR code, and then resume the normal page display of the operation guide. This form eliminates the need for the user to manually hide the QR code. Enlarged view of the code. It should be noted that the manner of hiding the enlarged view of the two-dimensional code is not limited to that described in this embodiment, and other forms, such as gesture control, other designated operation forms, etc., may also be adopted in practical applications.

Figure 12 shows an embodiment of an operation guide display method. The key is to display a two-dimensional code on a graphical user interface corresponding to the operation guide through a display device, and the terminal scans the two-dimensional code to push the information resources of the latest operation guide to Terminal, the method is configured to be executed by the controller 250 of the display device, that is, the controller 250 is the execution subject of the method, and the method includes the following program steps:

Step S101: In response to the first input instruction, display a graphical user interface corresponding to the operation guide for guiding the user to use the function of the display device.

Step S102: Detect the network connection status of the display device.

The first input instruction is an operation instruction input when the user starts the operation guide function. For example, when the user clicks the application icon of the operation guide through the control device 100 such as a remote control, the user interface 265 of the display device can receive the first operation instruction. Input instruction; or, for a display device that supports screen touch, the user generates the first input instruction when touching the application icon of the operation guide. The preset pages and information resources of the operation guide are pre-stored in the memory of the display device for easy recall and display at any time, and the operation guide can be loaded and displayed when the display device is not connected to the network.

Every time a user operates the guide application, the user graphical interface corresponding to the operation guide needs to be first displayed on the display. The graphical user interface may be the main page of the operation guide or a sub-page entered according to the user operation. The display device receives the first input When instructing, it is also necessary to detect the network connection status of the display device. The network connection status includes the network connected and the network disconnected, and step S101 and step S102 can be executed at the same time. You can directly detect the network status of the entire device in a conventional way; or use HTTP (Hyper Text Transfer Protocol) to request a lightweight page to detect the network status. Among them, the method of using HTTP to request a lightweight page to detect the connection status is specifically: controlling the browser to access the lightweight page; when the lightweight page is accessed normally, the resources and information of the lightweight page can be displayed normally , It is detected that the network status is network connected; when the lightweight page displays an access error or no network connection prompt, that is, the lightweight page displays abnormally, the network status is detected as network disconnected, light The access speed of the weight page is fast, which can improve the detection efficiency of the connection status, such as the Baidu page.

In step S103, it is judged whether the network connection status is that the network is connected. If it is, that is, when it is detected that the network connection state is that the network is connected, step S104 is executed; otherwise, if it is detected that the network connection state is that the network is not connected, step S107 is executed.

Step S104: Send a URL request corresponding to the operation guide in the server to the server.

When it is detected that the display device is connected to the network, the operation guide will first load the information resources of the display operation guide on the machine according to the country, language, device brand and other information, that is, after the operation guide is started and the QR code is not obtained, the display will display Preset page of operation guide. At the same time, the URL request corresponding to the QR code and the operation guide is sent to the server through the Https network. The URL request will carry the brand, model of the display device and the attribute information of the device itself, as well as the country, language and other information; the server responds to the URL request , The latest operation guide content adapted to the display device will be obtained, and the URL (Uniform Resource Locator, uniform resource locator) corresponding to the QR code will be issued to the display device according to the obtained latest operation guide content.

Step S105: Receive the URL issued by the server, and generate a QR code according to the URL.

When the URL of the two-dimensional code is received, the two-dimensional code corresponding to the operation guide is generated according to the URL. After the image of the two-dimensional code is obtained, the page of the operation guide can be refreshed.

Step S106: Control the display to display the two-dimensional code on a graphical user interface corresponding to the operation guide, so that the user can scan the two-dimensional code with a terminal device to view the operation guide.

After the page is refreshed, a thumbnail of the QR code will be displayed at its designated location, and other pages of the operation guide need to be synchronized to add the thumbnail of the QR code at the designated location. For example, if the current page of the operation guide is the main page, then You need to add a thumbnail of the QR code in the upper right corner of the main page, and simultaneously add the thumbnail of the QR code in the upper right corner of each sub-page under the main page, so that when the user clicks to enter any sub-page, it will be You can see the QR code thumbnail displayed in the upper right corner, so that the user can scan the QR code on any page of the operation guide. After scanning, the terminal device will immediately display the information resources of the pushed operation guide.

In this embodiment, when the user starts the operation guide, the connection status of the display device is detected. If it is detected that the network is connected, a URL request is sent to the server, and then the generated QR code is displayed according to the URL of the QR code issued by the server , After the terminal device scans the QR code, the information resources included in the pushed operation guide can be displayed on the terminal device. The server can issue the URL of the corresponding QR code according to the latest content of the operation guide. As long as the display device is connected to the network, the content of the operation guide can be updated synchronously through the QR code and pushed to the terminal device. After scanning the QR code, the latest operation guide content will be displayed. The display device side displays the original content of the operation guide when it is preset, and the two-dimensional code is added to the operation guide adaptively through the network. The user can refer to the guidance of the operation guide displayed on the terminal device, and operate and set the display device at the same time to realize the display device Pushing to the resources of the terminal improves the experience function of the operation guide, and improves the interaction between the display device and the terminal, and the actual application experience of the user is better.

When the user browses the page of the operation guide, he can see the thumbnail of the QR code displayed at the specified location of the page. At this time, the user can input the second input instruction, which is the operation input when the user enlarges the QR code Instructions, for example, the user can click the thumbnail of the QR code by remote control or touch control, etc. After the thumbnail of the QR code is clicked, the enlarged view of the QR code will be displayed on the upper layer of the current page, and the enlargement of the QR code will be displayed. Below the figure can be configured with prompt information to guide the user's operation. The enlarged image of the QR code is relative to the thumbnail. The enlarged image can be the original QR code image obtained after the QR code URL is generated, or the thumbnail is appropriately enlarged by a certain multiple, but the image must be clear In order to ensure the accuracy of QR code recognition, it is also necessary to ensure that the size of the enlarged image is moderate and not too large or too small.

After the user successfully scans the QR code, in order to make the enlarged image of the QR code no longer cover the page, the enlarged image of the QR code needs to be hidden, that is, the QR code is restored to be displayed as a thumbnail, which is convenient for the user to view the page At this time, the user can input the third input instruction, which is the operation instruction input when the user hides the enlarged view of the QR code. For example, the user can click on the QR code by remote control or touch control. Enlarge the image to hide the enlarged image of the QR code. This method is mainly based on the user's manual operation; or the terminal device automatically generates the scanned instruction information in response to the successful scanning of the QR code, and sends the scanned instruction information For the display device side, after the display device receives the scanned instruction information, it can control to hide the enlarged view of the QR code, and then resume the normal page display of the operation guide. This form eliminates the need for the user to manually hide the enlarged view of the QR code. It should be noted that the manner of hiding the enlarged view of the two-dimensional code is not limited to that described in this embodiment, and other forms, such as gesture control, other designated operation forms, etc., may also be adopted in practical applications. Among them, the display and hiding effects of the enlarged image of the QR code are not limited. For example, the enlarged image of the QR code is displayed in the form of pop-up, slide-out or gradually enlarged, and the effect of gradually shrinking, dissolving, blurring, etc. is used to hide the QR code. Zoom in.

Step S107, the two-dimensional code is not displayed on the graphical user interface corresponding to the operation guide.

When the display device is not connected to the network, the operation guide application will continue to display the information resources preset on the machine loaded according to the country, language, device brand and other information, that is, it will display the page preset in the operation guide. The home page preset in the operation guide The QR code is not displayed on the face and each sub-page. When the network is in a connected state, in accordance with the above steps S104 to S106, on the basis of the page preset in the operation guide, a thumbnail showing the QR code is added at the specified location.

In practical applications, the connection status of the display device may change. For example, when the user starts the operation guide, the display device is not connected to the network, but the device is connected to the network during the operation guide, that is, the connection status is switched from the network disconnected. If the network is connected, then you need to follow the above steps to display the thumbnail of the QR code on the refreshed page; if the network status changes from network connected to network disconnected, because the QR code scanning depends on the terminal device The network (such as 4G, 5G or WIFI, etc.) is not the network of the display device, so the display device can maintain the display of the QR code thumbnail displayed at the moment before the network is disconnected. Therefore, the network status in this application does not use a one-time acquisition method, but adaptively adjusts the display of the QR code according to changes in the network status.

In this regard, in this embodiment, the method of real-time monitoring of network status changes can be adopted. Once the broadcast information of network status changes is monitored, the page displayed on the display needs to be updated according to the newly acquired network status; or, the network monitoring network periodically is used. In the state method, the network connection state of the display device is obtained every preset time. The preset time can be adaptively set according to factors such as the actual network environment and application requirements, for example, 60 seconds.

In other possible implementations, when the display device is running the operation guide application, and the display device is always connected to the network during this period, the QR code can be updated online in time, for example, the server detects the operation of a display device If the content of the guide is updated, the URL of a new QR code adapted to the operation guide of the display device can be generated based on the updated content, and the URL of the new QR code can be issued to the display device. The URL of the QR code is refreshed to refresh the page to update the displayed QR code thumbnail.
