[0040] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. 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.

[0041] The present invention relates to the field of wireless communication technology, and in particular to high-definition screen projection technology for scenarios such as smart homes, office meetings, and entertainment and leisure. With the rapid development of Internet of Things technology, users have an increasing demand for interconnection between smart terminals, especially in the pursuit of ultimate experience such as ultra-low latency, high-definition image quality, and stable connection. The technical solution of the present invention combines Star Flash technology with the open source Hongmeng system to provide an efficient, reliable, and convenient screen projection solution to meet the wide application needs of future smart homes, remote offices, online education, and other fields.

[0042] The ultra-low latency high-definition screen projection method based on Star Flash technology and open source Hongmeng system described in the preferred embodiment of the present invention is as follows Figure 1 As shown, the ultra-low latency high-definition screen projection method based on Star Flash technology and the open source Hongmeng system includes the following steps:

[0043] Step S10: Design a screen projection application framework based on the open source Hongmeng system, and deploy the screen projection application framework on the user source device.

[0044] Specifically, a screen projection application framework based on the open source Hongmeng system is designed, and the Xingshan communication module is integrated to realize the underlying support of the screen projection function. The screen projection application framework based on the open source Hongmeng system includes:

[0045] (1) Star Flash Communication Module: This is the core part of the screen projection application framework and is responsible for wireless communication between devices. The Star Flash Communication Module uses the low latency, high rate, high concurrency, high reliability, and anti-interference characteristics of Star Flash technology to ensure stable and fast data transmission during the screen projection process.

[0046] (2) Screen projection control module: responsible for managing the screen projection function, including operations such as starting, stopping, and switching. It is also responsible for processing user input, such as selecting the target screen projection device and adjusting the screen projection settings.

[0047] (3) Content processing module: responsible for processing screen projection content, such as video, audio, pictures, etc., including encoding and decoding functions to ensure that the content maintains high quality during transmission.

[0048] (4) User Interface (UI): The user interface is the interface through which users interact with the screen projection application framework. It provides an intuitive operation method, allowing users to easily start screen projection, select devices, adjust settings, etc.

[0049] (5) Device discovery and pairing module: responsible for discovering available target projection devices and achieving fast pairing between devices. It uses Star Flash's low-power access technology (SLE) or basic access technology (SLB) to discover and connect devices.

[0050] (6) Security module: responsible for ensuring data security during the screen projection process, including encryption, authentication and other functions to prevent unauthorized access and data leakage.

[0051] (7) Cross-platform compatibility layer: Since the screen projection application framework needs to support multiple devices, it includes a cross-platform compatibility layer to ensure that it can run normally on different operating systems and devices.

[0052] Regarding the deployment location of the screen projection application framework, it can be deployed on the user source device (such as a mobile phone, tablet), or on the target screen projection device (such as a large-screen TV, projector), or on both at the same time, depending on the specific screen projection requirements and device capabilities. In the present invention, it is preferably deployed on the user source device. For example, if the user source device has powerful processing capabilities and a Star Flash communication module, then the main part of the screen projection application framework may be deployed on the user source device; if the target screen projection device has better display capabilities and a Star Flash communication module, then the relevant part of the screen projection application framework may be deployed on the target screen projection device. In actual applications, the screen projection application framework may need to be flexibly deployed according to different scenarios and devices.

[0053] Step S20: The user source device selects the target screen projection device on the user interface of the open source Hongmeng system through the device discovery and pairing module in the screen projection application framework.

[0054] Step S30: The user source device establishes pairing and wireless communication connection with the target screen projection device through the Star Flash communication module in the screen projection application framework.

[0055] Specifically, users select the target screen projection device (such as a large-screen TV) through the user interface of the open source Hongmeng system, and use StarFlash technology's low-power access technology (SLE) or basic access technology (SLB) for quick pairing and connection.

[0056] The specific process of fast pairing and connection using Star Flash's low-power access technology (SLE) or basic access technology (SLB) is as follows:

[0057] (1) Device discovery: The user starts the screen casting application on the user source device (such as a mobile phone or tablet) and selects the target screen casting device (such as a large-screen TV) through the user interface. The screen casting application will send a broadcast signal and use the device discovery function of Star Flash technology to search and display a list of available target screen casting devices.

[0058] (2) Device selection: The user selects the target device to be connected from the target device list. The screen projection application will record the user's selection and prepare for device pairing.

[0059] (3) Low Power Access Technology (SLE): If the user chooses to use Star Flash's low power access technology (SLE) for pairing, the user's source device will send a low-power pairing request to the target projection device. After receiving the request, the target projection device will respond in low power mode to reduce energy consumption. This technology is suitable for devices that need to save energy, such as mobile devices.

[0060] (4) Basic Link Technology (SLB): If the user chooses to use the basic link technology (SLB) of Star Flash technology for pairing, the user's source device will send a basic link request to the target projection device. After receiving the request, the target projection device will respond in standard mode. This technology is suitable for devices that do not require special energy saving, such as fixed devices.

[0061] (5) Pairing process: Whether using SLE or SLB, the pairing process includes device authentication and encryption steps to ensure the security of the connection. The user source device and the target projection device will exchange authentication information and establish a secure communication channel.

[0062] (6) Connection establishment: Once pairing is successful, a stable wireless connection will be established between the user's source device and the target projection device. The high concurrency capability of Star Flash technology ensures that the connection remains stable even in a multi-device environment.

[0063] (7) User confirmation: Finally, the user may see a confirmation interface on the user's source device, prompting that the screen projection connection has been established and allowing the user to start screen projection.

[0064] Through the above steps, using the low-power access technology (SLE) or basic access technology (SLB) of Star Flash technology, users can quickly and safely complete device pairing and connection and start the screen projection function. This fast pairing and connection capability makes the screen projection application of Star Flash technology in scenarios such as smart home, remote office, and online education more efficient and convenient.

[0065] Step S40: The user source device confirms the user's screen projection connection instruction and screen projection content selection instruction through the screen projection control module in the screen projection application framework.

[0066] Step S50: The user source device confirms the user's screen projection connection instruction and screen projection content selection instruction through the screen projection control module in the screen projection application framework;

[0067] Step S60: The user source device processes the projection content according to the projection content selection instruction through the content processing module in the projection application framework, and sends the processed projection content to the target projection device through the Star Flash communication module for projection display.

[0068] Specifically, after the screen projection function is activated, the high-speed transmission capability of the Star Flash technology is used to transmit high-definition video, audio and other content on the user's source device (such as a mobile phone or tablet) to the target screen projection device in real time. At the same time, the intelligent scheduling algorithm of the open source Hongmeng system is used to optimize the transmission path, reduce latency and improve image quality.

[0069] The intelligent scheduling algorithm is a key component in the open source Hongmeng system, which is used to optimize the transmission path of the projection content. It includes the following strategies:

[0070] (1) Route optimization: The intelligent scheduling algorithm selects the best transmission path based on the network topology and device status. It considers factors such as the path’s bandwidth, latency, and packet loss rate to ensure efficient and stable content transmission.

[0071] (2) Load balancing: The intelligent scheduling algorithm monitors the load of each node in the network and dynamically adjusts the data flow to avoid overloading of certain nodes, thereby improving the transmission efficiency of the entire network.

[0072] (3) QoS (Quality of Service) guarantee: The intelligent scheduling algorithm assigns different priorities to different projection contents to ensure the transmission quality of key contents (such as video streams).

[0073] (4) Real-time adjustment: The intelligent scheduling algorithm can respond to changes in network status in real time, such as device movement, network congestion, etc., and dynamically adjust the transmission strategy to adapt to the ever-changing network environment.

[0074] (5) Multi-path transmission: If possible, the intelligent scheduling algorithm will take advantage of the high concurrency capability of Star Flash technology to transmit data simultaneously through multiple paths to improve transmission rate and reliability.

[0075] Through these intelligent scheduling algorithms, the open source Hongmeng system can optimize the transmission path, reduce latency, and improve image quality, thereby providing users with a smoother, higher-quality screen projection experience. The implementation of these algorithms relies on the modular design and openness of the open source Hongmeng system, allowing developers to customize and optimize according to specific application scenarios and network environments.

[0076] The present invention also monitors the stability of the screen projection connection in real time, utilizes the anti-interference capability of Star Flash technology, and promptly responds to possible interference sources to ensure the continuity and stability of the screen projection process.

[0077] Monitoring the stability of the projection connection involves real-time monitoring and analysis of a variety of data. The following are the monitored data and their indications of stability:

[0078] (1) Signal strength: Monitor the strength of the star flash signal. A high signal strength indicates a good connection quality and strong stability.

[0079] (2) Data transmission rate: Monitor the data transmission rate. If the rate is stable and reaches the expected value, it means the connection is stable.

[0080] (3) Packet loss rate: monitors packet loss during data transmission. A low packet loss rate indicates good connection quality and high stability.

[0081] (4) Latency: Monitors the latency of data transmission. Low and stable latency indicates fast connection response and good stability.

[0082] (5) Interference level: Monitors the electromagnetic interference level. A low interference level means that the connection is not susceptible to external interference and has high stability.

[0083] (6) Device status: Monitor the operating status of the projection device and the source device, such as device temperature, processor load, etc. Good status indicates stable device operation, which indirectly reflects the connection stability.

[0084] (7) User feedback: Collect user feedback on the screen projection experience, such as whether the picture is smooth and the sound is synchronized. Good user feedback indicates high connection stability.

[0085] By monitoring this data, the system can evaluate the stability of the screen projection connection in real time. If abnormal data is detected, such as a sudden drop in signal strength, an increase in packet loss rate, or latency fluctuations, the system will trigger corresponding response mechanisms, such as automatically adjusting transmission parameters, switching transmission paths, and notifying users, to ensure the continuity and stability of the screen projection process.

[0086] When an abnormality is detected, the methods for dealing with or resolving the interference source include the following aspects:

[0087] (1) Interference detection: First, the system needs to be able to detect the presence of interference. This can be achieved by analyzing parameters such as signal quality, data transmission rate, and packet loss rate. Once an anomaly is detected, the system will trigger the interference response mechanism.

[0088] (2) Dynamic frequency selection: Star Flash technology may have the ability of dynamic frequency selection, which can automatically select a frequency with the least interference for data transmission based on the interference situation in the current environment.

[0089] (3) Signal enhancement: When interference is detected, the system can increase the power of the transmitted signal to improve the signal's resistance to interference.

[0090] (4) Error correction coding: Star Flash technology may use advanced error correction coding technology, such as 5G Polar coding. This coding technology can correct transmission errors caused by interference to a certain extent.

[0091] (5) Multi-path transmission: By utilizing the high concurrency capability of Star Flash technology, the system can transmit data simultaneously through multiple paths. In this way, even if one of the paths is disturbed, the other paths can still ensure stable data transmission.

[0092] (6) Adaptive modulation: The system can dynamically adjust the modulation method according to the current interference situation and select the modulation technology that is most effective in the current environment.

[0093] (7) Interference source location and avoidance: If possible, the system can try to locate the interference source and take measures to avoid the interference, such as by adjusting the device position or changing the transmission direction.

[0094] (8) User notification and intervention: In the event of severe interference, the system can notify the user and provide some intervention measures, such as turning off nearby electronic devices, adjusting the location of the device, etc.

[0095] Through these methods, the system can effectively deal with interference sources and ensure the stability and reliability of the screen projection connection.

[0096] The present invention also collects user feedback, performs iterative optimization on problems encountered during the screen projection process, and continuously improves the user experience.

[0097] The collection of user feedback is usually completed by the following roles or systems:

[0098] (1) User interface: The user interface of the screen projection application can be designed with feedback collection functions, such as satisfaction surveys, problem reporting buttons, etc. Users can submit their feedback directly through these interface elements.

[0099] (2) Automatic feedback system: The system can automatically collect some user behavior data, such as screen projection frequency, connection stability, user operation habits, etc. These data can be used as part of user feedback.

[0100] (3) Customer service and support team: If users contact customer service through channels such as phone, email, social media, etc., the customer service team can collect user feedback and record it in the system.

[0101] (4) App store and market feedback: If the screen projection application is provided in the app store, users can leave feedback in the comment section of the app store, which can be collected and analyzed by the developer.

[0102] (5) Data Analysis Team: The data analysis team can regularly analyze the collected user feedback and extract key information for product improvement.

[0103] (6) Developers and engineers: Developers can directly participate in collecting user feedback, especially during user testing or beta testing, where they may communicate directly with users to obtain feedback.

[0104] (7) Social media and online communities: Through social media platforms and online communities, users can share their usage experiences, and developers can collect user feedback through these channels.

[0105] The collected user feedback will be used for iterative optimization of the product to enhance the user experience. This may include fixing known bugs, improving the user interface, optimizing performance, adding new features, etc. By continuously collecting and responding to user feedback, developers can ensure that the screen projection technology solution continues to meet user needs and expectations.

[0106] Iterative optimization is an ongoing process that involves analyzing user feedback, identifying problems, designing and implementing solutions, and evaluating results. The following are the specific steps for iterative optimization:

[0107] (1) Collect user feedback: Collect user feedback through channels such as user interface, automatic feedback system, customer service and support team, app store reviews, social media and online communities.

[0108] (2) Analyze feedback data: Classify and analyze the collected feedback data to identify the problems, needs and suggestions encountered by users.

[0109] (3) Prioritization: Prioritize the identified issues based on their severity and impact.

[0110] (4) Develop solutions: Develop solutions for high-priority issues. This may include fixing bugs, improving functions, optimizing performance, etc.

[0111] (5) Development and testing: Developers develop code based on the solution and conduct internal testing and user testing to ensure the effectiveness and stability of the solution.

[0112] (6) Deployment of updates: Deploy tested updates to the production environment and make them available to all users.

[0113] (7) Monitor results: After deploying the update, monitor the system’s performance and user feedback to evaluate the effectiveness of the solution.

[0114] (8) Continuous improvement: Based on monitoring results and new user feedback, continue to iterate and optimize to continuously improve the product.

[0115] The goal of iterative optimization is to ensure that the screen projection technology solution can continue to meet user needs and provide a high-quality experience. Through this process, developers can ensure that their products remain competitive and adapt to the ever-changing market and technology environment.
