Description

Technical Field

[0001] This invention relates to the field of network operation and maintenance management of satellite communication systems. In response to the problem that it is impossible to quickly locate and eliminate abnormal phenomena such as stuttering in satellite video transmission, a video transmission quality monitoring and evaluation system based on satellite channels is proposed. Background Technology

[0002] In satellite-based video transmission, the current requirements for satellite video technology assurance are not clearly defined, and the video quality characterization indicators are not clear enough. When there are anomalies in satellite video, there is a lack of effective means to assist in the diagnosis, location, and rapid processing of video anomalies, which cannot meet the requirements for real-time monitoring, rapid adjustment, and technical assurance of video quality in satellite video transmission systems. Summary of the Invention

[0003] This invention addresses the problem of the inability to quickly locate and resolve anomalies such as stuttering during video transmission in satellite communication systems. It proposes a video transmission quality monitoring and evaluation system based on satellite channels. By designing an intelligent monitoring, evaluation, and management device and adapting it to intelligent monitoring, evaluation, and management software, the system collects, analyzes, and evaluates the operational performance indicators of satellite radio frequency (RF) equipment. Furthermore, it generates equipment parameter adjustment strategies for video anomalies, enabling dynamic adjustment of the RF equipment parameters.

[0004] To achieve the above objectives, the present invention adopts the following design scheme:

[0005] A video transmission quality monitoring and evaluation system based on satellite channels includes intelligent monitoring, evaluation and management equipment and a satellite communication system. The intelligent monitoring, evaluation and management equipment includes a performance monitoring probe and an intelligent monitoring, evaluation and management system.

[0006] The performance monitoring probe is used to interconnect with satellite radio frequency equipment to obtain real-time operating performance index information of satellite radio frequency equipment in the satellite communication system, report the operating performance index information to the intelligent monitoring and evaluation management system, and distribute the satellite radio frequency equipment parameter adjustment strategy sent by the intelligent monitoring and evaluation management system to the relevant satellite radio frequency equipment in the satellite communication system.

[0007] The intelligent monitoring and evaluation management system is used to persist the operational performance index information of satellite radio frequency equipment reported by the performance monitoring probes and present the operational performance trend of the equipment in real time. When abnormal phenomena occur in the satellite video, alarm prompts are generated, and satellite radio frequency equipment parameter adjustment strategies are generated and sent to the performance monitoring probes.

[0008] Furthermore, the intelligent monitoring and evaluation management system includes an interface adaptation module, a data processing module, a performance analysis and evaluation module, a performance monitoring and presentation module, a knowledge base management module, and a system management and configuration module.

[0009] The interface adaptation module is used to realize the interface adaptation between the intelligent monitoring and evaluation management system and the performance monitoring probe. The interface content includes probe status, satellite radio frequency equipment operation performance index information and satellite radio frequency equipment parameter adjustment strategy. It outputs the satellite radio frequency equipment operation performance index information to the data processing module, outputs the satellite radio frequency equipment parameter adjustment strategy to the corresponding performance monitoring probe, and reports the probe status to the system management module.

[0010] The data processing module is used to process the satellite radio frequency equipment operation performance index information collected by the interface adaptation module through the performance monitoring probe, generate performance data models according to the satellite radio frequency equipment type, and output them to the performance analysis and evaluation module and the performance monitoring and presentation module.

[0011] The performance analysis and evaluation module is used to fuse the performance data model and the video quality alarm threshold model to generate a performance evaluation model, which is then sent to the knowledge base management module. At the same time, it generates an alarm command when the performance data exceeds the threshold and outputs the alarm command to the performance monitoring and presentation module. It is also used to receive parameter adjustment strategies from the knowledge base management module and transmit them to the interface adaptation module.

[0012] The performance monitoring and presentation module is used to present real-time and historical performance data of satellite radio frequency equipment in graphical and list formats, and to generate alarm prompts after receiving video quality alarm commands;

[0013] When the knowledge base management module receives the performance evaluation model sent by the performance analysis and evaluation module, it uses a matching algorithm to match the corresponding parameter adjustment strategy from the knowledge base and outputs the parameter adjustment strategy to the performance analysis and evaluation module.

[0014] The system management and configuration module is used to configure and manage the video quality alarm threshold model, output the video quality alarm threshold model to the performance analysis and evaluation module, manage the status of the performance monitoring probe, and output knowledge base information to the knowledge base management module.

[0015] The advantages of this invention compared to the prior art are:

[0016] The system of this invention analyzes and evaluates the performance data of relevant satellite radio frequency equipment that affects video quality, generates dynamic adjustment strategies for equipment parameters, ensures the smoothness and reliability of video transmission, and improves the comprehensive management and control capabilities and network application capabilities of satellite video.
