[0071] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0072] It should be noted that, although the functional modules are divided in the system schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the system or the order in the flowchart. The terms "first / S100", "second / S200", etc. in the specification, claims and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0073] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0074] On the one hand, if Figure 1 As shown, the embodiment of the present invention provides an IPTV browser 100 for a large-screen terminal, which may include a kernel layer 110, a standard interface layer 120, a JS extension layer 130 and an application adaptation layer 140; specifically:

[0075] The kernel layer is used to perform multi-threaded rendering processing on the web page syntax based on the preset rendering engine;

[0076] It should be noted that, in some embodiments, the kernel layer may include: a rendering engine for rendering hypertext markup language, cascading style sheets and / or scripting language; a multi-threaded processing unit for splitting the various processing tasks of the rendering processing into different processing threads for multi-threaded processing when the rendering processing includes multiple processing tasks.

[0077] In some optional embodiments, the kernel layer may further include: a GPU acceleration unit, which is used to call the GPU-assisted rendering processing of the large-screen terminal to perform image acceleration.

[0078] For example, in some specific implementations, the rendering engine is a core component of the kernel layer, which is responsible for parsing and rendering Hypertext Markup Language (HTML), Cascading Style Sheets (CSS), and scripting languages ​​(such as JavaScript). These languages ​​together constitute the main content and structure of a web page. The rendering engine builds a DOM tree by parsing HTML documents; builds a rendering tree by parsing CSS and applies styles; and implements dynamic interaction and updates of web pages by executing JavaScript.

[0079] In the kernel layer, the optimization of the rendering engine is crucial to improving browser performance and user experience. It can adopt various optimization strategies, such as lazy loading, asynchronous rendering, smart scrolling, etc., to reduce rendering delays and increase page loading speed.

[0080] The multi-threaded processing unit is another important component of the kernel layer. It is responsible for splitting multiple processing tasks in the rendering process into different processing threads for parallel processing. This can fully utilize the multi-core advantages of modern processors and improve the efficiency and speed of rendering processing.

[0081] The multithreaded processing unit may include components such as a task scheduler and a thread pool. The task scheduler is responsible for assigning rendering tasks to different threads to ensure load balancing and efficient execution between tasks. The thread pool is responsible for managing a group of available threads, reducing the overhead of thread creation and destruction, and improving thread utilization.

[0082] The GPU acceleration unit is a component in the kernel layer that is used to call the GPU of the large-screen terminal for image acceleration. In the rendering process, some complex image operations (such as 3D rendering, video decoding, etc.) may require a large amount of computing resources. By utilizing the parallel computing capabilities of the GPU, the execution efficiency of these operations can be significantly improved.

[0083] The GPU acceleration unit works closely with the rendering engine and multi-threaded processing unit to ensure that GPU resources can be efficiently called when needed. It may include components such as the GPU driver interface and image acceleration algorithm to achieve data exchange and image acceleration processing between the GPU and the CPU.

[0084] Some examples of specific application scenarios are described below:

[0085] Suppose there is a large-screen terminal browser that needs to load and render a web page containing a large number of images and animations in a short time. The HTML document of this web page is very large and contains multiple CSS style sheets and JavaScript scripts.

[0086] The role of the rendering engine:

[0087] The browser first uses the rendering engine to parse the HTML document and build the DOM tree.

[0088] Next, the rendering engine parses the CSS style sheet, builds a rendering tree, and applies the style to the DOM tree.

[0089] Finally, the rendering engine executes JavaScript scripts to update the DOM tree and rendering tree to achieve dynamic interaction and updates of web pages.

[0090] The role of the multi-threaded processing unit:

[0091] During the rendering process, the multi-threaded processing unit splits the rendering task into multiple subtasks, such as parsing HTML, parsing CSS, executing JavaScript, etc.

[0092] These subtasks are assigned to different processing threads for parallel processing to improve rendering efficiency.

[0093] For example, one thread is responsible for parsing HTML documents, another thread is responsible for parsing CSS style sheets, and another thread is responsible for executing JavaScript scripts.

[0094] The role of GPU acceleration unit:

[0095] When a web page contains complex image operations (such as 3D animation, video decoding, etc.), the GPU acceleration unit is called.

[0096] It uses the GPU resources of large-screen terminals to accelerate these image operations.

[0097] For example, when a 3D animation in a web page needs to be rendered, the GPU acceleration unit passes the animation data to the GPU for parallel calculation, and then returns the calculation results to the rendering engine for rendering.

[0098] Through the collaboration of these components, large-screen terminal browsers can load and render web pages containing large numbers of images and animations in a short time, providing a smooth user experience.

[0099] The standard interface layer is used to abstract and encapsulate the kernel layer and build a standard browser interface.

[0100] It should be noted that in some embodiments, a security mechanism is preset in the standard interface layer; the standardized interface layer is also used to identify, intercept and process security threats based on the preset security mechanism; among them, security threats include cross-site scripting attacks and cross-site request forgery.

[0101] For example, in some specific implementations, the standard interface layer is a key component of the browser architecture, which is located above the kernel layer and is mainly responsible for abstracting and encapsulating the functions of the kernel layer, thereby building a set of standardized browser interfaces. These interfaces provide a unified way for upper-layer applications (such as web developers, browser extensions, etc.) to access the kernel layer functions, ensuring the stability and consistency of browser functions.

[0102] The design of the standard interface layer follows the principles of modularity, scalability, and security. Through modular design, the standard interface layer divides different functions into independent modules, reduces the coupling between modules, and improves the maintainability of the system. At the same time, the standard interface layer also provides scalability, allowing developers to add new interfaces and functions according to needs.

[0103] In the standard interface layer, security mechanisms can be preset to cope with increasingly complex network security threats. These security mechanisms include but are not limited to:

[0104] Input validation: Strictly validate and filter the data entered by users to prevent security issues caused by malicious input.

[0105] Permission control: Based on the user's identity and role, fine-grained control is provided over access rights to ensure that only authorized users can access sensitive resources and perform sensitive operations.

[0106] Data encryption: Encrypt the transmitted data to prevent it from being stolen or tampered with during transmission.

[0107] Full audit: record and analyze system operation logs to promptly detect and respond to abnormal behaviors.

[0108] As part of the security mechanism, the standard interface layer also has the ability to identify and intercept common security threats such as cross-site scripting attacks (XSS) and cross-site request forgery (CSRF).

[0109] XSS identification and interception: By filtering and encoding input data, malicious scripts are prevented from being injected into web pages and executed. At the same time, the standard interface layer can also dynamically monitor web page content to promptly detect and block the execution of malicious scripts.

[0110] SRF identification interception: By checking the source and legitimacy of the request, it prevents attackers from using the user's identity to send malicious requests to the server. For example, the standard interface layer can require that all sensitive operations must contain a valid authentication token (such as a CSRF token) and be verified on the server side.

[0111] Some examples of specific application scenarios are described below:

[0112] Assume that there is a web application based on the above browser architecture, which needs to process the form data submitted by the user and save the data on the server. In order to ensure the security of the application, the security mechanism in the standard interface layer plays an important role.

[0113] Input validation: When a user submits a form, the standard interface layer first validates and filters the input data. For example, for the text content entered by the user, the standard interface layer checks whether it contains malicious scripts or special characters, and escapes or deletes these contents.

[0114] CSRF protection: Before the form is submitted, the standard interface layer generates a unique CSRF token and embeds it in a hidden field of the form. When the user submits the form, the server checks whether the request contains a valid CSRF token and verifies the legitimacy of the token. If the token is invalid or expired, the server will refuse to process the request.

[0115] Data encryption: During data transmission, the standard interface layer will encrypt sensitive data. For example, when a user submits a form, the standard interface layer will use the HTTPS protocol to encrypt the data for transmission, ensuring that the data is not stolen or tampered with during transmission.

[0116] Through the combined effect of these security mechanisms, the standard interface layer provides strong security protection for web applications, effectively preventing security threats such as cross-site scripting attacks and cross-site request forgery.

[0117] The JS extension layer is used to provide an extension function for the IPTV browser in response to a preset extension script;

[0118] It should be noted that, in some embodiments, the JS extension layer may include: a custom extension API unit, used to obtain an extension script according to a preset custom extension API interface; wherein the API interface is used to realize two-way communication between the extension script and the IPTV browser; a script injection unit, used to inject the extension script into a predetermined process of loading a web page in the IPTV browser; and a debugging tool, used to develop and debug the extension script in response to the debugging instructions of the development object.

[0119] For example, in some specific implementations, the JS extension layer is an important component of the IPTV browser architecture, which allows developers to add additional functions to the IPTV browser by writing JavaScript extension scripts. This mechanism not only enhances the flexibility of the browser, but also enables the browser to better adapt to different application scenarios and user needs.

[0120] The custom extension API unit is one of the core components of the JS extension layer. It provides a set of preset API interfaces that allow the extension script to communicate with the IPTV browser in a two-way manner. Through these API interfaces, the extension script can access the core functions of the browser, such as DOM operations, network requests, storage management, etc., and can also send events or data to the browser to achieve interaction with the browser.

[0121] The design of the custom extension API unit follows the principles of openness and extensibility. Developers can define new API interfaces according to their own needs and add them to the custom extension API unit. In this way, as IPTV browsers develop and application scenarios continue to change, the JS extension layer can flexibly adapt to new needs and add more functions to the browser.

[0122] The script injection unit is responsible for injecting the extension script into the predetermined process of loading the web page in the IPTV browser. This process usually occurs at a certain stage of web page loading, such as when DOM loading is completed, page rendering is completed, etc. By precisely controlling the timing of script injection, it is possible to ensure that the extension script runs in the correct environment and avoid conflicts with other scripts in the web page.

[0123] The script injection unit also provides management functions for injected scripts. Developers can enable or disable a certain extension script when needed, or adjust the injection order and priority of the script as needed. These functions make the JS extension layer more flexible and controllable.

[0124] The debugging tool is an indispensable part of the JS extension layer. It allows developers to debug and test extension scripts in real time during the development process. Through the debugging tool, developers can view the script's running status, variable values, function call stack and other information, so as to quickly locate and solve problems in the script.

[0125] The debugging tool also supports advanced features such as breakpoint debugging, single-step execution, and variable monitoring, allowing developers to have a deeper understanding of the script's execution process and behavior. In addition, the debugging tool can also be integrated with the browser's developer tools to provide developers with a more comprehensive debugging experience.

[0126] Some examples of specific application scenarios are described below:

[0127] Suppose there is an IPTV browser that needs to implement a custom bullet screen function through the JS extension layer. To implement this function, you can follow the steps below:

[0128] Define a custom extension API: First, you need to define an API interface in the custom extension API unit to implement the barrage function. This interface should provide functions such as sending barrage, receiving barrage, and setting barrage style.

[0129] Write an extension script: Next, write a JavaScript extension script to implement the bullet screen function. This script will use the custom extension API interface to communicate with the IPTV browser to send and receive bullet screens.

[0130] Configure the script injection unit: Then, you need to configure the injection timing and order of the extension script in the script injection unit. In this example, you can choose to inject the extension script immediately after the web page is loaded to ensure that the barrage function can work properly.

[0131] Debugging with debugging tools: Finally, use debugging tools to debug and test the extension script. Through the debugging tools, you can view the running status of the barrage function, the barrage information sent and received, and other information to ensure that the barrage function can work properly and meet user needs.

[0132] Through the above steps, you can use the JS extension layer to implement a customized bullet screen function for the IPTV browser to enhance the browser's functions and user experience.

[0133] The application adaptation layer is used to perform province-by-province adaptation based on the parameters of large-screen terminals;

[0134] It should be noted that, in some embodiments, the parameters include interface size and page display requirements; the application adaptation layer may include: a user interface optimization unit, used to adapt the layout of the rendered web page according to the interface size; a resolution adaptation unit, used to dynamically adapt the resolution of the web page according to the page display requirements of different web pages.

[0135] For example, in some specific implementations, the application adaptation layer is a crucial part of large-screen terminal application development. It is responsible for targeted adaptation and optimization of applications based on the specific parameters of large-screen terminals, such as screen size, resolution, display capabilities, etc., to ensure that applications can present the best visual effects and user experience on large-screen terminals. The core goal of this layer is to achieve cross-device and cross-platform compatibility while maximizing the display advantages of large-screen terminals.

[0136] The parameters are explained in detail as follows:

[0137] Interface size: The interface size of large-screen terminals is usually much larger than that of traditional mobile devices. Therefore, the application adaptation layer needs to make corresponding adjustments to the application layout, font size, image size, etc. to ensure that the content can be displayed clearly and beautifully on the large screen.

[0138] Page display requirements: Different web pages may have different display requirements, such as video pages need to support high-definition playback and full-screen display, news pages need to optimize text layout and image display, etc. The application adaptation layer needs to dynamically adjust the resolution, loading speed, and interaction mode of the web page based on these requirements.

[0139] The application adaptation layer components are described as follows:

[0140] User interface optimization unit: This unit is mainly responsible for adapting the layout of rendered web pages according to the interface size of large-screen terminals. By adjusting the layout structure, element spacing, font size, etc. of the page, the page content is made more coordinated and beautiful on the large screen. In addition, the unit can also optimize the interaction mode of the page according to the user's operating habits to improve the user experience.

[0141] Resolution Adaptation Unit: This unit focuses on the resolution adaptation of web pages. It can dynamically adjust the resolution of the page according to the display requirements of different web pages to ensure that the content can maintain clarity and readability at different resolutions. For example, on the video playback page, the unit can automatically adjust the video resolution to adapt to the high-definition display requirements of large-screen terminals; on the news reading page, it can optimize the resolution and loading method of the image to reduce loading time and improve the reading experience.

[0142] Some examples of specific application scenarios are described below:

[0143] Assume that there is a large-screen terminal with a screen size of 100 inches and a resolution of 4K (3840x2160). Now, a web application containing news list and video playback functions needs to be displayed on the large-screen terminal.

[0144] Application of the User Interface Optimization Unit:

[0145] For the news list page, the user interface optimization unit can adjust the news title font size, summary length and image size, so that each news can be clearly displayed on the large screen while keeping the page neat and beautiful.

[0146] For the video playback page, the unit can optimize the layout of the video player so that it occupies most of the area of ​​the large-screen terminal to provide an immersive viewing experience. At the same time, the size and position of the player's control buttons can be adjusted to facilitate user operation on the large screen.

[0147] Application of resolution adaptation unit:

[0148] On the news list page, the resolution adaptation unit can dynamically adjust the overall resolution and image quality of the page according to the content density of the page and the user's reading habits. For example, in areas with dense content, the image resolution can be appropriately reduced to speed up loading; while in areas with sparse content, the image resolution can be increased to improve the reading experience.

[0149] For video playback pages, the unit can automatically detect and adjust the video resolution to ensure that the video can be played clearly on large-screen terminals. If the resolution of the video source is lower than the resolution of the large-screen terminal, the unit can also try to use super-resolution technology to improve the clarity of the video.

[0150] By applying these components and functions of the adaptation layer, we can ensure that web applications can present the best visual effects and user experience on large-screen terminals.

[0151] In some optional embodiments, the application adaptation layer may also include: a key adaptation unit, which is used to adapt and transmit key events to the large-screen terminal by intercepting and processing key events; a syntax error adaptation unit, which is used to correct and adapt the page error syntax of the specified error page based on pre-injected script data.

[0152] For example, in some specific implementations, the key adaptation unit plays a vital role in the application adaptation layer of the large-screen terminal. Since the physical keys or touch areas of the large-screen terminal may be significantly different from those of conventional mobile devices, the key adaptation unit is responsible for intercepting and processing key events from the user to ensure that these events can be correctly and efficiently transmitted to the application layer for processing.

[0153] The main functions of the key adapter unit include:

[0154] Key event interception: This unit can monitor and intercept all key events from the user, including pressing and releasing physical keys, touching and sliding the touch area, etc.

[0155] Event adaptation and delivery: After intercepting a key event, the unit will adapt the event according to the characteristics of the large-screen terminal and the needs of the application. This may include adjusting the triggering conditions of the event, modifying the parameter value of the event, or converting the type of the event. Then, the unit will pass the adapted key event to the application layer so that the application can process it accordingly.

[0156] Custom key mapping: In order to meet the specific needs of large-screen terminals, the key adapter unit also supports custom key mapping. This means that users or developers can map a physical key or touch area to a specific function or operation in the application as needed, thereby providing a more convenient and personalized operating experience.

[0157] The syntax error adaptation unit is another important component of the application adaptation layer. It is mainly responsible for detecting and correcting syntax errors in web pages to ensure that the page can be displayed correctly and smoothly on large-screen terminals.

[0158] The main functions of the syntax error adaptation unit include:

[0159] Error Detection: This unit can perform real-time syntax checking on web pages based on pre-injected script data. It will identify and mark syntax errors in the page, such as missing HTML tags, incorrect writing of CSS attributes, etc.

[0160] Error correction: After detecting a syntax error, the unit will try to correct the error. This may include automatically completing missing tags, modifying incorrect attribute names or values, deleting redundant code, etc. The corrected page will be able to more accurately reflect the developer's intentions and present a better display effect on large-screen terminals.

[0161] Error log recording: To facilitate subsequent troubleshooting and optimization, the syntax error adaptation unit will also record all detected syntax errors and their corrections. These log information can help developers understand potential problems in the page and take corresponding measures to improve them.

[0162] Some examples of specific application scenarios are described below:

[0163] Suppose there is a large-screen terminal and the user is using a web application that includes video playback and online shopping functions.

[0164] Application of key adapter unit:

[0165] On the video playback page, users may want to use physical buttons to control the playback and pause of the video. The button adaptation unit can intercept these button events and map them to corresponding functions in the application. For example, when a user presses a specific physical button, the button adaptation unit will recognize it as a "play / pause" operation and pass the operation to the video playback component for processing.

[0166] On an online shopping page, users may want to use the touch area to browse product lists and select products. The key adaptation unit can monitor touch and slide events in the touch area and adapt these events according to the user's operating habits and application requirements. For example, when the user slides the touch area, the key adaptation unit can adjust the sliding speed and distance so that the user can browse the product list more easily.

[0167] Application of syntax error adaptation unit:

[0168] On the video playback page, if there are syntax errors in the web page code (such as missing HTML tags), this may cause the video to not play properly or the page to display abnormally. The syntax error adaptation unit can detect these errors and try to automatically complete the missing tags or correct the incorrect attributes. The corrected page will be able to display the video content normally and provide a better user experience.

[0169] On an online shopping page, if there are syntax errors in the HTML code of the product list (such as incorrect writing of CSS attributes), this may cause the display style of the product list to be abnormal. The syntax error adaptation unit can detect these errors and automatically modify the incorrect attribute name or value. The corrected page will be able to correctly display the style and layout of the product list, thereby improving the user's shopping experience.
