Description

Technical Field

[0001] This invention proposes a method and system for coordinated volume control of a television and a set-top box based on the number of key value transmissions by a remote control, belonging to the cross-technical fields of human-computer interaction in smart home appliances, infrared remote control technology and multi-device coordinated control. Background Technology

[0002] Current universal infrared remote controls for volume control of TVs and set-top boxes generally employ device-binding logic. Users need to manually switch control modes, and pressing the "volume + / -" button only sends infrared key codes to the target device. This solution has significant drawbacks in infrared connection scenarios: First, it lacks coordination. The TV and set-top box volumes are controlled independently, but the final perceived loudness is the product of the two. When the TV volume is too low, the user needs to perform four cumbersome steps: exiting the set-top box signal source, switching control modes, increasing the TV volume, and switching back to the set-top box. Second, it has a status blind spot. The one-way communication characteristic of infrared means that the remote control cannot know the current volume status of the set-top box, making it difficult to implement intelligent strategies such as threshold judgment. Third, it is development-dependent. If a Bluetooth / Starflash solution is used, the set-top box needs to have status reporting capabilities, which is incompatible with existing infrared set-top boxes. Summary of the Invention

[0003] This invention provides a method and system for coordinated volume control of a television and set-top box based on the number of key value transmissions by a remote control, in order to solve the problems mentioned in the background art above:

[0004] This invention proposes a method for coordinated volume control of a television and a set-top box based on the number of key value transmissions using a remote control, characterized in that the method includes:

[0005] S1. Initialize the remote control, set up the "Volume +" key value sending count recording and difference accumulation value calculation module, record the "Volume +" key value sending count and calculate the difference accumulation value; the "Volume -" key value recording is only associated with TV volume adjustment and does not participate in the difference accumulation;

[0006] S2. Based on the current "Volume+" key value, send the cumulative difference value data to simulate and judge the set-top box volume status; if the threshold is not reached, generate a synchronous adjustment command; if the threshold is reached or exceeded, generate a command to adjust only the TV; "Volume-" key operation directly generates a command to adjust only the TV.

[0007] S3. Control the infrared key code transmission according to the instruction, and synchronously adjust the instruction to send the set-top box "volume +" key code in batches, and only adjust the TV instruction to send the corresponding key code; record the transmission timestamp to generate data;

[0008] S4. By using volume adjustment timestamp data and combining it with the initial volume settings of the TV and set-top box, the volume coordination effect is verified; the actual changes in the volume of the TV and set-top box at different time points are analyzed to verify the effectiveness of the coordination control method; at the same time, based on the verification results, the preset threshold of the cumulative difference value is dynamically adjusted to generate optimized cumulative difference value threshold data.

[0009] S5. Based on the optimized cumulative difference threshold data, update the volume coordination control strategy in the remote control; operate according to the new strategy thereafter; at the same time, provide feedback on the optimization strategy and its effect, and generate coordination control optimization feedback data.

[0010] This invention proposes a remote control-based volume coordination control system for televisions and set-top boxes based on the number of key value transmissions, comprising:

[0011] One or more processors;

[0012] Memory, used to store one or more programs;

[0013] Wherein, when the one or more programs are executed by the one or more processors, the one or more processors are made to implement the method described in any one of the above.

[0014] The beneficial effects of this invention are as follows: First, this method simulates the set-top box volume status through cumulative differential values, achieving one-click collaborative adjustment. Users do not need to manually switch control modes; they only need to press the "volume + / -" button once to complete the operation, compressing the original cumbersome four-step process into one step, improving operational efficiency by 75%. Second, considering the unidirectional transmission characteristics of infrared, this method does not require set-top box feedback. It determines whether to send set-top box key codes based on the cumulative differential value on the remote control, solving the status blind spot problem and ensuring compatibility with existing infrared set-top boxes, thus reducing development costs. Third, this method sets a threshold for the cumulative differential value (e.g., 100). When the threshold is reached, only the TV volume is adjusted, avoiding distortion caused by excessively high set-top box volume, thus balancing loudness requirements and sound quality protection. Finally, the strategy of always adjusting only the TV volume with the "volume-" button avoids subsequent superposition failures caused by excessively low set-top box volume, ensuring loudness continuity.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] One embodiment of the present invention, such as Figure 1 and Figure 2 and Figure 3 As shown, a method for coordinated volume control of a television and a set-top box based on the number of key value transmissions by a remote control is disclosed. The method includes:

[0020] S1. Initialize the remote control settings, establish a "Volume+" key value transmission count recording module and a difference accumulation value calculation module; when the user presses the "Volume+" key, record the number of times the key value is transmitted, and calculate the difference with the previous record according to preset rules. Accumulate the difference to the difference accumulation value calculation module to generate the current "Volume+" key value transmission difference accumulation value data; at the same time, set the "Volume-" key value transmission record as an independent path only associated with the TV volume adjustment, and do not participate in the difference accumulation calculation;

[0021] S2. Based on the current "Volume+" key value, send the cumulative difference value data to simulate and judge the set-top box volume status; when the cumulative difference value does not reach the preset threshold (e.g., 100), determine that the set-top box volume needs to be adjusted synchronously, and generate a set-top box volume synchronous adjustment command; when the cumulative difference value reaches or exceeds the preset threshold, determine that only the TV volume needs to be adjusted to protect the sound quality, and generate a command to adjust only the TV volume; at the same time, for the "Volume-" key operation, directly generate a command to adjust only the TV volume, without triggering the set-top box volume adjustment;

[0022] S3. Based on the set-top box volume adjustment command or the command to adjust the TV volume only, perform infrared key code transmission control; for the set-top box volume adjustment command, send the set-top box "volume+" key code in batches to simulate the process of gradually increasing the set-top box volume; for the command to adjust the TV volume only, send only the TV "volume+" or "volume-" key code to achieve independent adjustment of the TV volume; at the same time, record the timestamp of each key code transmission to generate volume adjustment timestamp data;

[0023] S4. By using volume adjustment timestamp data and combining it with the initial volume settings of the TV and set-top box, the volume coordination effect is verified; the actual changes in the volume of the TV and set-top box at different time points are analyzed to verify the effectiveness of the coordination control method; at the same time, based on the verification results, the preset threshold of the cumulative difference value is dynamically adjusted to generate optimized cumulative difference value threshold data.

[0024] S5. Based on the optimized cumulative difference threshold data, update the volume coordination control strategy in the remote control; during subsequent use, record the number of times the "volume+" key value is sent, calculate the cumulative difference, and generate volume adjustment commands according to the new strategy; at the same time, feed back the optimized control strategy and volume adjustment effect to the remote control manufacturer or related service platform to provide data support for subsequent product iterations and generate volume coordination control optimization feedback data.

[0025] The working principle and effects of the above technical solution are as follows:

[0026] Through automatic scene recognition and batch key value sending mechanisms, volume adjustment can be achieved with a single click without manually switching TV / set-top box control modes. This reduces the tedium of multi-step operations, avoids the time wasted by repeatedly switching devices, and improves the efficiency of volume adjustment. By distinguishing between synchronous and discrete audio output scenarios, synchronous scenarios link both devices, while discrete scenarios control only the set-top box. This avoids misunderstandings caused by a lack of feedback during adjustments, reducing user confusion and enhancing the smoothness of the user experience. By setting an 80%-90% set-top box volume threshold and dynamic optimization strategies, sound quality distortion caused by excessive volume is avoided, reducing ineffective adjustments and sound quality degradation, and improving the balance between loudness requirements and sound quality protection. By adapting to mainstream Bluetooth / starlight / infrared connection methods, infrared scenarios do not require additional development for the set-top box, reducing development costs for device adaptation, avoiding compatibility issues with existing devices, and enhancing the universality of the technical solution. Through volume adjustment effect feedback and dynamic threshold optimization, a "use-verification-iteration" closed loop is formed, reducing inadequate adaptation caused by rigid control strategies, avoiding the limitations of fixed thresholds, and improving the accuracy and flexibility of collaborative control.

[0027] In one embodiment of the present invention, S1 includes:

[0028] S11. Initialize the hardware function modules of the universal remote control, build a module for recording the number of times the "volume+" key value is sent and a module for calculating the cumulative difference value, configure the data interaction link between modules, and generate a module initialization completion signal.

[0029] S12. Preset the "Volume-" key value sending rules, clarify that it is an independent control path that is only associated with the TV volume adjustment, configure path isolation parameters, and generate "Volume-" key control path configuration data;

[0030] S13. Real-time monitoring of user key press operations. When the "volume+" key trigger signal is detected, the number of key value transmissions is captured and stored through the count recording module, and single "volume+" key value transmission record data is generated.

[0031] S14. Call the difference accumulation value calculation module to calculate the single-transmission difference based on the preset algorithm (current transmission count - previous transmission count), and add this difference to the accumulation value to generate the current "volume +" key value transmission difference accumulation value data. The difference definition and initial value are as follows:

[0032] The difference is defined as the difference between the current number of times the "volume+" key value is sent and the number of times the "volume+" key value was sent last time, that is: difference = current number of times sent - previous number of times sent.

[0033] During remote control initialization, the "Volume+" key value transmission count recording module and the difference accumulation value calculation module are reset. At this time, the initial value of the "Volume+" key transmission count is set to 0, and the initial value of the difference accumulation value is also set to 0.

[0034] The working principle and effects of the above technical solution are as follows:

[0035] By building a dedicated recording and difference calculation module and configuring a data interaction link, the stability of data transmission between modules was improved, reducing data loss or delays and providing a reliable foundation for subsequent volume coordination judgment. By pre-setting an independent control path for the "Volume-" key and configuring isolation parameters, the logic confusion between it and the "Volume+" key difference calculation was avoided, reducing the probability of incorrect control command generation and enhancing the accuracy of key control. By real-time monitoring of the "Volume+" key trigger signal and capturing and storing the number of transmissions, the integrity of key value transmission data was ensured, statistical errors were reduced, and the accuracy of cumulative difference calculation was improved. By calculating single differences using a pre-set algorithm and accumulating them, effective difference data was quickly generated, avoiding data loss during subsequent threshold judgment, reducing response delays in coordinated control, and enhancing the timeliness of volume adjustment decisions.

[0036] In one embodiment of the present invention, S13 includes:

[0037] Start the real-time monitoring function of remote control button operation, activate the signal capture sensor, establish a button trigger signal monitoring link, and generate a monitoring start-up ready signal;

[0038] By monitoring the link to capture the electrical signals triggered by the user's key presses in real time, the signal characteristics (such as key value encoding and trigger duration) are identified and analyzed to generate key signal characteristic data;

[0039] Compare the button signal feature data with the preset "volume +" button standard feature library to determine whether it is triggered by the target button and generate button type recognition results;

[0040] When the recognition result is "volume+" key, the count recording module is invoked to extract the cumulative number of times the current key value is sent and update it, generating key value sending count update data;

[0041] The updated number of times the "volume+" key value is sent is encrypted and stored, and the trigger time node is associated to generate a record of each "volume+" key value sending.

[0042] The working principle and effects of the above technical solution are as follows:

[0043] By activating the monitoring function and establishing a dedicated signal link, the stability of key-triggered signal capture is improved, reducing signal interruptions or missed captures, and providing a continuous and reliable foundation for subsequent key value recording. Signal characteristics are analyzed and compared with a standard feature library to improve the recognition accuracy of the "volume+" key, reduce the probability of misjudging it with other keys, and avoid invalid adjustment operations caused by recognition errors. The number of transmissions is updated in real time after identifying the target key to ensure the timeliness of data recording, reduce the lag in count statistics, and provide real-time and effective data support for difference accumulation calculation. Encrypted storage of recorded data and association with time nodes enhance data security and integrity, prevent data tampering or loss, improve the credibility of key value transmission records, and provide accurate basis for subsequent collaborative control decisions.

[0044] In one embodiment of the present invention, S2 includes:

[0045] S21. Collect the generated cumulative difference data and preset volume threshold parameters (e.g., 100), and integrate them into a threshold judgment input dataset;

[0046] S22. Perform threshold comparison judgment on the input dataset. When the cumulative difference value does not reach the preset threshold, determine that the set-top box volume needs to be increased synchronously and generate a set-top box volume synchronous adjustment instruction.

[0047] S23. When the cumulative difference value reaches or exceeds the preset threshold, it is determined that the set-top box volume has reached a reasonable range. In order to protect the sound quality, only the TV volume needs to be adjusted, and a command to adjust only the TV volume is generated.

[0048] S24. Independently monitor the "Volume-" button trigger signal, and generate independent instructions to adjust only the TV volume without calling the difference accumulation module;

[0049] S25. Standardize the format of the above-mentioned commands and integrate them to generate a unified volume adjustment command set to ensure that the commands can be accurately recognized by the TV and set-top box.

[0050] The working principle and effects of the above technical solution are as follows:

[0051] By integrating cumulative difference data with preset thresholds to generate an input dataset, the comprehensiveness of threshold judgment is improved, and misjudgments caused by missing data are reduced, providing a reliable basis for generating adjustment commands. Adjustment commands are generated differentially according to threshold ranges; when the threshold is not reached, the set-top box is adjusted simultaneously, and when the threshold is reached, only the TV is adjusted. This avoids distortion due to excessive volume, reduces ineffective adjustments, and improves the balance between sound quality protection and adjustment efficiency. To address the issue of the cumulative difference value continuously increasing due to a long press of the "Volume +" button, a preset threshold is set so that when the cumulative difference value reaches or exceeds the threshold, the remote control will only send a volume adjustment command to the TV, instead of sending the "Volume +" button code to the set-top box. This strategy ensures that even if the cumulative value exceeds the threshold due to a long press, the remote control can still adjust the TV volume according to the user's intention, while avoiding excessive increase in the set-top box volume. The "Volume-" button command is handled independently without calling the difference module, avoiding logic interference, reducing command generation delay, enhancing operational consistency, and preventing subsequent loudness superposition failure; various commands are processed in a standardized manner and integrated into a unified set, improving the accuracy of command recognition by the TV and set-top box, reducing adjustment failures caused by command incompatibility, and enhancing the stability of control logic.

[0052] In one embodiment of the present invention, step S21 includes:

[0053] Determine the core data types required for threshold judgment, lock in two key data types: cumulative difference value data and preset volume threshold parameters, and generate a data collection list;

[0054] Call the data interface to extract the current "volume+" key value generated in step S1 and send the difference accumulation value data. Verify the data integrity (no missing or outlier values) and generate valid difference accumulation data that has passed the verification.

[0055] Read the preset volume threshold parameter (e.g., 100) built into the remote control, and perform a second verification of the threshold's rationality in conjunction with the sound quality protection standard to generate valid threshold data that has passed the verification.

[0056] The effective data of cumulative difference and effective data of threshold are structured and integrated using a unified data format (such as JSON format), and the data source and collection timestamp are labeled to generate the input dataset for threshold judgment.

[0057] The working principle and effects of the above technical solution are as follows:

[0058] By identifying core data and generating a collection list, the system improves the targeting of data collection, avoids interference from irrelevant data, reduces the redundant burden of subsequent processing, and allows threshold judgment to focus on key information. It extracts difference data and verifies its integrity, filtering out missing and abnormal data to improve the reliability of accumulated difference data, reduce threshold misjudgments caused by data issues, and lay a solid foundation for the judgment results. It also performs secondary verification of thresholds in conjunction with sound quality standards to ensure that thresholds meet sound quality protection requirements, avoid sound quality distortion or ineffective adjustments caused by unreasonable thresholds, and enhance the scientific nature of threshold settings. Finally, it unifies the format of data integration and annotates metadata, making the data structure clear and traceable, improving the processing efficiency of subsequent threshold comparison and judgment, reducing parsing obstacles caused by format incompatibility, and ensuring a smooth judgment process.

[0059] In one embodiment of the present invention, S3 includes:

[0060] S31. Parse the generated volume adjustment instruction set, extract the corresponding parameters, including instruction type (set-top box synchronous adjustment / TV independent adjustment), key code sending quantity, and generate key code sending configuration parameters.

[0061] S32. In response to the set-top box volume synchronization adjustment command, send the set-top box "volume+" key code in batches according to the configuration parameters to simulate the continuous adjustment process of gradually increasing the set-top box volume and generate a batch sending log of set-top box key codes.

[0062] S33. For commands that only adjust the TV volume, send the corresponding TV key code separately according to the button type ("volume +" / "volume -") to perform independent and precise adjustment of the TV volume, and generate an independent TV key code sending log.

[0063] S34. Timestamp each key code sending action and record the corresponding information, including the sending time, key code type, and receiving device, and generate a volume adjustment sending record with timestamps.

[0064] S35. Verify the integrity of the key code transmission, confirm that there are no omissions or errors in transmission, generate key code transmission verification results, and ensure that the adjustment command is effectively transmitted.

[0065] The working principle and effects of the above technical solution are as follows:

[0066] Parsing the instruction set and extracting key parameters improves the accuracy of key code transmission configuration, avoids parameter omissions or misreadings, reduces the probability of subsequent transmission logic errors, and lays the foundation for precise adjustment. Batch transmission of set-top box key codes simulates continuous adjustment, reducing the user's burden of repetitive button presses, improving volume boost efficiency, and avoiding discontinuous adjustment caused by single transmissions. Individual transmission of TV key codes by key type enhances the independence and accuracy of TV volume adjustment, avoids interference with set-top box adjustments, and reduces adjustment deviations. Timestamps mark transmission information, improving the traceability of adjustment records, facilitating subsequent effect verification and problem troubleshooting, and reducing difficulties in fault location due to lack of records. Verifying the integrity of key code transmission ensures no omissions or errors, improves the reliability of instruction transmission, reduces adjustment failures caused by key code transmission problems, and guarantees the effectiveness of collaborative control.

[0067] In one embodiment of the present invention, S32 includes:

[0068] Filter out the set-top box synchronization adjustment type instruction from the key code sending configuration parameters, lock the target execution instruction, and generate the set-top box batch sending target instruction;

[0069] Extract the key code sending core parameters from the target instruction. The sending core parameters include the number of sending and the sending time interval. Combine the key code receiving response characteristics of the set-top box to optimize the sending timing and generate key code batch sending execution parameters.

[0070] The infrared key code sending module is started according to the execution parameters, and the "volume +" key code of the set-top box is sent in batches in sequence. The timing control simulates the continuous effect of gradually increasing volume and generates key code sending stream data.

[0071] Record the sequence number, sending time, key code value, and receiving device feedback status of each key code transmission in real time, and generate a detailed record of key code batch transmission;

[0072] Integrate the sending details and mark key information, including instruction number, total number of sendings, and execution time, to generate a standardized set-top box keycode batch sending log.

[0073] The working principle and effects of the above technical solution are as follows:

[0074] Precisely select set-top box synchronization adjustment commands, lock onto the target execution object, improve the targeting of command execution, avoid interference from irrelevant commands, and reduce ineffective adjustments caused by missent commands; optimize the transmission timing based on the set-top box's receiving response characteristics, making key code transmission more compatible with device performance, improving key code reception success rate, and reducing transmission stuttering or reception failure; batch send key codes and simulate continuous adjustment through timing control, reducing the user's burden of repeated key presses, improving volume boosting efficiency, and avoiding discontinuous adjustment caused by single transmissions; record key code transmission details and device feedback status in real time, improve the traceability of the adjustment process, facilitate subsequent problem investigation, and reduce the difficulty of fault location due to lack of detailed records; integrate and generate standardized transmission logs, making the data structure clear and unified, improving the convenience of subsequent collaborative effect verification, and reducing analysis obstacles caused by data chaos.

[0075] In one embodiment of the present invention, step S4 includes:

[0076] S41. Collect timestamped transmission records and initial volume setting data of TV and set-top box, and integrate them to build a volume coordination effect verification dataset;

[0077] S42. Based on the validation dataset, analyze the actual volume change curves of the TV and set-top box at different time points, compare them with the preset adjustment target, evaluate the response speed and adjustment accuracy of the collaborative control, and generate a volume collaboration effect analysis report.

[0078] S43. Based on the analysis report, determine whether the current preset threshold is suitable for different volume scenarios (such as low initial volume, high initial volume), evaluate the impact of the threshold on sound quality protection and adjustment efficiency, and generate a threshold rationality assessment suggestion.

[0079] S44. Based on the evaluation recommendations, the preset threshold of the cumulative difference value is optimized and corrected through a dynamic adjustment algorithm to avoid excessively high thresholds leading to redundant adjustment or excessively low thresholds affecting loudness, thereby generating optimized cumulative difference value threshold data.

[0080] The working principle and effects of the above technical solution are as follows:

[0081] By integrating timestamped records and initial volume data to construct a verification dataset, the integrity and correlation of the data are improved, the evaluation bias caused by single data points is reduced, and comprehensive support is provided for effect analysis. Analyzing the volume change curves of dual devices and comparing them with preset targets accurately assesses response speed and adjustment precision, improving the objectivity of the collaborative control effect judgment and reducing misjudgments of control performance. Combining analysis reports to determine threshold scenario adaptability balances sound quality and adjustment efficiency, enhancing the scientific nature of threshold settings and reducing the limitations of fixed thresholds in adapting to different scenarios. Dynamic algorithms are used to optimize and correct thresholds, avoiding excessively high thresholds that lead to adjustment redundancy or excessively low thresholds that affect loudness, improving the rationality of thresholds and reducing user experience issues caused by inappropriate thresholds. A closed loop of data acquisition, analysis, evaluation, and threshold optimization is formed, enhancing the iterative capability of the control strategy, making collaborative adjustment more aligned with actual needs, and reducing the inadequacy of adaptation caused by rigid strategies.

[0082] In one embodiment of the present invention, S42 includes:

[0083] From the volume coordination effect verification dataset, the TV volume data and set-top box volume data corresponding to each time point are filtered, sorted by time series, and a time-series volume subdivision dataset is generated.

[0084] Data visualization algorithms are used to process the time-series volume subdivision dataset, draw volume change trend curves for TVs and set-top boxes, mark key adjustment nodes (such as key code sending time), and generate volume change curve charts for both devices.

[0085] Extract the core evaluation metrics from the curve charts. The response speed metric includes the delay time from key code transmission to volume change, and the adjustment accuracy metric includes the deviation between the actual volume and the preset target. Generate the metric extraction results.

[0086] The extracted indicators are compared with preset adjustment target thresholds (such as delay ≤100ms, deviation ≤5%) to analyze the compliance of collaborative control in different scenarios and generate indicator comparison analysis data.

[0087] By integrating time-series data, change curves, and indicator comparison results, we can identify the advantages in response speed, the shortcomings in adjustment accuracy, and the directions for optimization, and generate a standardized volume coordination effect analysis report.

[0088] The working principle and effects of the above technical solution are as follows:

[0089] Filtering and sorting time-series volume data improves data orderliness and correlation, reduces interference from messy data in the analysis, and provides a systematic basis for subsequent trend judgment. Plotting volume change curves for both devices and marking key nodes makes the adjustment process visually clear, improves the identification of trends, and reduces the difficulty and error of pure data interpretation. Extracting core indicators such as delay time and deviation values ​​allows the evaluation to focus on key dimensions, improving the accuracy of judging the effect of collaborative control and avoiding vague assessments. Comparing indicators with preset thresholds clarifies the achievement status and gaps, improves the objectivity of judgment, and reduces misjudgments caused by subjective assumptions. Integrating multi-dimensional data to generate standardized reports clearly identifies advantages, disadvantages, and optimization directions, improving the targeting of subsequent threshold adjustments and reducing the ineffective costs of blind optimization.

[0090] In one embodiment of the present invention, step S5 includes:

[0091] S51. Receive the generated optimized threshold data, update the volume coordination control strategy parameters inside the remote control, replace the original threshold configuration, and generate the updated complete volume coordination control strategy.

[0092] S52. During subsequent use of the remote control, the updated strategy is used to record the number of times the "volume+" key value is sent, calculate the cumulative difference, and generate volume adjustment commands, generating real-time strategy execution data.

[0093] S53. Continuously collect volume adjustment effect data during strategy execution (such as user key presses, final loudness satisfaction, sound quality feedback, etc.) and generate a strategy execution effect evaluation report.

[0094] S54. Synchronize the updated control strategy and execution effect evaluation report to the remote control manufacturer or related service platform to form product iteration support data and generate volume collaborative control optimization feedback dataset.

[0095] The working principle and effects of the above technical solution are as follows:

[0096] The system receives optimized threshold updates to control strategies, replaces outdated and unreasonable configurations, improves the adaptability of strategies to actual usage scenarios, reduces adjustment deviations caused by fixed thresholds, and makes collaborative control more precise. It executes key-value recording and difference calculations according to the updated strategy specifications, improving the consistency of the execution process, reducing logical loopholes during strategy implementation, and enhancing the stability of control operations. It continuously collects actual effect data such as user keystroke counts and loudness satisfaction, making evaluations more aligned with real-world usage needs, reducing blind optimizations detached from user experience, and increasing the reference value of feedback data. It synchronizes strategies and evaluation reports with the manufacturer, providing accurate data support for hardware upgrades and algorithm optimization, enhancing the targeting of product iterations, and reducing ineffective R&D investment. This forms a closed-loop mechanism of strategy update-execution-feedback-iteration, allowing the control solution to continuously adapt to different scenarios, reducing the experience degradation caused by strategy rigidity, and improving the sustainability of the technical solution.

[0097] In one embodiment of the present invention, S54 includes:

[0098] Clearly define the target objects for data synchronization (remote control manufacturers, related service platforms), sort out the core data that needs to be synchronized (updated control strategies, implementation effect evaluation reports), and generate a data synchronization list;

[0099] According to the data reception specifications of the target object, the data in the synchronization list is standardized in format (e.g., uniformly converted to XML format), and metadata such as data version number and generation time are added to generate a standardized synchronization data package.

[0100] Establish an encrypted transmission link (such as the HTTPS protocol), encrypt standardized synchronization data packets, verify the stability and security of the link, and generate a transmission readiness confirmation signal.

[0101] Initiate the data transmission process, push synchronization data packets to the target object, monitor the transmission progress in real time, receive the reception confirmation information from the other party, and generate a data transmission completion log;

[0102] The data synchronization list, standardized synchronization data packets, transmission completion logs, and reception confirmation information are integrated and structured into product iteration support data, generating a complete volume collaborative control optimization feedback dataset.

[0103] The working principle and effects of the above technical solution are as follows:

[0104] Clearly define the synchronization targets and core data and generate a list to improve the targeting of data synchronization, avoid redundant transmission of irrelevant data, and reduce the burden of data screening for target objects; standardize data according to the receiving specifications and supplement metadata to improve data compatibility and readability, reduce parsing obstacles caused by format incompatibility, and enhance data traceability; establish an encrypted transmission link and verify its security to improve the confidentiality of data transmission, reduce the risk of leakage of core strategies and assessment data, and enhance the reliability of the transmission process; monitor the transmission progress in real time and receive confirmation information to improve the transparency of the transmission status, reduce data packet loss or non-delivery, and ensure the complete transmission of data; integrate multiple types of data to form product iteration support data, improve the accuracy of subsequent R&D optimization, reduce resource waste caused by blind iteration, and enhance the support of feedback data for product upgrades.
